If you think that detergents are found only on supermarket shelves, then be prepared for a clean, green surprise. It grows on trees and has been cleaning clothes (and people) since the time of the Buddha! In fact, some sources also add the Buddha to its list of satisfied consumers.

Say hello to the Sapindus – a group of around 10 species of trees whose fruits can be used as foaming cleaners or surfactants to use a more technical term. The unique surfactant property of the Sapindus fruit makes it an all purpose cleaner – for skin, hair, laundry, dishes and pretty much anything else that requires cleaning.

The name Sapindus is derived from the Latin words Saponis, meaning soap and Indicus, meaning from India. The part of the Sapindus tree used as a surfactant is the fruit and it is commonly known as soapnut. Since it is a fruit We prefer to call it the soapberry which is more accurate.

The Soapberry tree

India is home to several species of Sapindus. The two most well known of these are the South Indian Sapindus trifoliatus and the Himalayan Sapindus Mukorossi. In India, soapberries have a long recorded history of usage. Ayurvedic texts prescribe it as a gentle cleansing agent in shampoos and body cleansers and also as a treatment in dermatitis, and eczema.

In China the soapberry pericarp is called wu-huan-zi or the non illness fruit. In Japan, the soapberry pericarp is called the enmei-hi or the life prolonging pericarp.

The Soapberry

Fresh soapberry fruits look like grapes or gooseberry fruits and grow in clusters on the trees.

A well cared for soapberry tree can produce 250 kg of soapberry fruits every year, after attaining maturity which takes about ten years.

What makes the soapberry a soap?

The magic ingredient which gives the soapberry its halo is saponin, found in the fleshy outer part of the fruit.

The pericarp of the soapberries (the outer fleshy part of the fruit) contains saponins, which are the plants “immune system”. Saponins are a class of compounds, found in abundance in the plant world, and produce foaming solutions in water which can used for cleaning.

How can I use the soapberry in my home?

The soapberry is an excellent natural cleanser that can be used to substitute most synthetic cleansers in your home.

You can use the soapberry shells , soapberry powder, or extract soapberry liquid by making a concentrated tea with water and use this as a substitute for almost all your cleaning needs.

It can be used in the following ways:

1.    As a mild shampoo substitute

2.    As safe and effective detergent

3.    As a hypoallergenic baby fabric detergent

4.    As a food safe dish wash product

5.    As an excellent antibacterial / anti-fungal floor and surface cleanser

What are other uses of the Soapberry ?

Plants are wonderfully complex systems that are beyond complete human understanding. All along we have only talked about the surfactant property but the soapberry does so much more than just clean.

1. Pesticide removal action: fruits and vegetables

Soapberry powder works wonders on removing surface level pesticides in fruits and vegetables as well. Research done on tomatoes, aubergines, cabbage and grapes, which have a thin membrane and are prone to absorbing a large quantity of pesticides, indicates a 76% reduction in deadly pesticides like Monocrotophos, when these fruits and vegetables are soaked for 20 minutes in a solution of water and soapberry powder.

2.    Pesticide removal action: on cotton

Cotton is one of the most sprayed crops in the world. In India, cotton crop is sprayed with a deadly cocktail of chemicals including Lindane, Heptachlor, and DDT.

A simple test measuring the surface level pesticides on cotton yarn before and after treatment with soapberry, showed nearly a 70% reduction in the surface levels of Lindane.

3. Anti-bacterial and anti-fungal action

Soapberries have strong anti-fungal and anti-bacterial properties. They have been prescribed in small quantities in oral medications in traditional Chinese medicine.

Extracts of Sapindus mukorossi were shown to inhibit the bacterium Helicobacter pylori which causes GERD, peptic ulcers, cancers of the oesophagus and stomach

Preliminary studies on Sapindus mukorossi and Sapindus saponaria show active action against many disease causing fungi like Candida albicans, and bacteria like Pseudomonas Aeruginosa and Staphylococcus Aureus

How do I start using the soapberry?

Fresh soapberry fruits need to be dried well to be used. Once dried, they become a rich dark brown colour, depending on the species and look like this:

Once dried, they need to be de-seeded before they are ready for use.

Soapberries are extremely hygroscopic in nature, meaning that they absorb moisture from the atmosphere, so they need to be stored in a dry place.

1.Use whole soapberries

It  is  really easy to use soapberries for washing. If you’re using a washing machine, you may place 5– 6  shells in an old, clean sock or muslin bag firmly tied on top, so that the soapberries don’t escape. Toss this into the washing machine and let it work through both the wash and rinse cycles, but do remove before you use the dryer.

You can use the soapberries for upto 4 wash cycles, but remember to let them dry before the next wash.  You can use the soapberries until they turn grey in colour (indicating that there are no more saponins left). Best of all, as soapberries are completely natural and biodegradable, they can be composted.

2. Making soapberry powder from dried soapberries

For even better results and greater convenience, soapberry powder can be made by grinding dried, de-seeded soapberries.  They can be ground in a coffee grinder, and should be ground into large sized particles when used as a detergent or a dish wash product. The finer soapberries are ground, the faster they absorb moistures, so grinding them into large sized particles helps you store them for longer.

Soapberry powder can be used as a substitute to detergents and dish wash applications. Keep in mind that they do not dissolve completely like synthetic surfactants, so when using them in a washing machine or a dish washer, put the powder into a sock or muslin bag, to keep the residue from sticking onto laundry or dishes.

The residue after use as a detergent or dish wash makes for great plant food so do remember to compost the residue  after use.

3. Extracting Soapberry liquid

You can also extract soapberry liquid for use as a detergent or a floor cleanser. Soapberry liquid needs to be refrigerated and does not keep for more than a month.

It is prepared by soaking soapberries overnight in cold water or soaking them in hot water for 15 minutes to an hour and squeezing out the saponins mechanically until the berries turn grey in colour.

Let the soapberry liquid cool slightly before filtering out the soapberry residue. The residue can be dried and re-used again to make more floor cleanser (the cleanser made with this residue will be more dilute, so reduce the water the second time around) or to do the laundry. The soapberry powder / residue can be re-used until the residue turns grey, indicating the absence of saponins.

Do I have to work very hard to use the soapberry?

The soapberry is making a strong comeback into popular use especially in countries like USA, Australia, Singapore, India and other places.  A lot of the work done on the soapberry in recent times has been directed to making it readily usable so that you do not have to go through the process of buying the fruit and making a powder or extract.

Our company, Krya Consumer Products has just launched a washing machine ready soapberry detergent powder for the Indian market. Do search for options in your market in case you want a ready to use product and you will be rewarded with a unique experience in tasks like laundry which are getting done on autopilot mode now.

Why are we talking about the soapberry now?

We do many daily tasks like the laundry on autopilot now and understandably so. However several drastic concerns for the environment and human health are lurking behind many of these “autopilot” routines.

For example the synthetic detergent industry is red flagged for pollution by many governments. The red flags arise out of pollution concerns during manufacture and severe harm to water bodies and marine ecosystems by detergent residue post consumer use.

Apart from detergents many personal care products like shampoo, body wash, toothpaste use a synthetic surfactant as a foaming agent. Look for either sodium lauryl sulphate or sodium laureth sulphate (referred shortly as SLS) in the ingredient list the next time you are in the supermarket and you will be surprised by the number of times these two surfactants appear. There are many studies that point to these synthetic surfactants as carcinogens so much so that “SLS free “is an important new category of products.

Moving from autopilot to manual mode can throw up interesting natural alternatives to most of the products we use on ourselves and in the home. Every time you choose a natural alternative like the soapberry, you choose better health for your family and a cleaner planet.

I’m very happy to note that the article on “How to Make and Use Garbage Enzymes” has stirred a lot of discussion and this has been an opportunity to clarify where the science lies.

I had endorsed Garbage Enzymes enthusiastically as I have personally heard gardeners speak of the positively about the results. These are from 1) Ground-Up Initiative at Bottle Tree Park, Singapore 2) Kampung Senang Charity Foundation in the Community Garden at Tampines, Singapore 3) Bandar Harapan Organic Farm in Malaysia and 4) Nanyang Technological University Community Medicinal Herb Garden (which I discovered after writing the article).

The sum and substance of the feedback is that Garbage Enzymes (the term itself may be a misnomer) can be used as a homemade vinegar for non-edible cleaning purposes. The efficacy of Garbage Enzymes as a fertiliser or pesticide or an air purifier is not yet verified by scientific research.  Even less obvious is its ability to lessen greenhouse gases. There are varying views on its contribution to waste management – in the local context, is composting a better way to manage waste, instead of adding molasses? Or can this be considered as one additional way to manage waste that would otherwise go to the incinerator?

There are two detailed responses to this and we thank both the contributors for their time to clarify the science behind Garbage Enzymes.

The first response is from Dr Vinisha Khemani Kanjilal, who is a Singapore based scientist and runs science based educational programs for children at Green Dots

I read your piece on Garbage Enzymes (GE), and note a few things here:

• The process you describe without doubt is a natural fermentation/anaerobic oxidation whose products are alcohol (incomplete/partial fermentation) and acetic acid (complete fermentation). These are enzymatically performed by natural and mixed microbial cultures in the starting preparation (fruit dregs and vegetable trimmings).

• Fermentation has been used for time immemorial/centuries (and even before the science was clarified by Louis Pasteur) to produce wines and vinegars, sakes and arrack and other variants of these all over the world. Some native populations have preferred pure starting materials like rice bran or grapes, some have been clever to figure out anything with naturally combustible carbohydrates can be converted to sugars and be directed towards production of ethanol and/or acetic acid (aka vinegar). See Wikipedia on Fermentation.

• Thus GEs are not a new discovery by Dr. Rosukon Poompanvong or anyone else in recent times for that matter. Pubmed is a publically accessible repository of all original research published in peer reviewed journals – there is no mention of any work when a search is done on her. Also, the FAO link on her lists many of her achievements. However couldn’t find any English language literature on the internet of any credibility to all the GE uses you’ve listed out on the blog. She is perhaps to be credited for heightening the awareness around reuse of kitchen waste (traditionally discarded in Thailand?) towards production of vinegar via a method that can be simply executed by almost anybody.

• To the best of my knowledge neither the enzymes/biological catalysts from microbes (mostly proteins) nor the microbes themselves would survive the change in pH that happens during the course of a complete fermentation and none of the fruit based enzymes that I’m aware of viz: papain from papaya, bromelain from pineapple, etc. would function in the final and extreme acidic environment of approx.2 that would result when acetic acid is produced as in the GE method described.

• Thus the terminology GE is a bad one (even if but as a colloquial name) for the process described to recycle organic waste by fermentation (in no way attributable to EWTT), but just to be cautious in what it mistakenly connotes.

• In the scope of 3R principles even while trying to be vegetarian and all consuming there will be some organic waste generated. Whether that kitchen waste goes into composting or more pure vermiculture methods, to generate vinegar at home as a cleaner and by reproducing the process described or otherwise is immaterial. They are all effective as recycling methods and would have little to no difference in their pros and cons with respect to global warming, save the fact that an incomplete fermentation (as for example when yeast cultures are used to produce ethanol) actually produces a greenhouse gas as a byproduct viz: carbondioxide (CO2).

• In the same vein, directed waste management practices (See Wikipedia link on Anaerobic Digestion) that produce methane (an alternative source of energy and potent greenhouse gas) if not channelized towards use are effectively adding to global warming.

• Would not make any claims to use of vinegar whether produced by the GE process or otherwise as a fertilizer or pesticide at any concentration. There is no evidence for this whatsoever.

• Sometimes soils are more alkaline than required by plants to grow healthily…so diluted vinegar might help set the pH towards a more neutral or favourable setting…also just perhaps aid in soil loosening. This could be seen as largely beneficial but remains to be tested scientifically and would still not qualify GE as a natural fertlilizer.

• Likewise extreme environments would destroy most microbes so acetic acid like any other corrosive acid would kill some bugs on contact and if used carefully might be usable as a pesticide/insecticide. This potential benefit remains to be tested however in dose dependent studies.

In short would agree with John Cussman that the science presented and claims made on GE are  flawed and somewhere effective microbial cultures that would be enzymatically rich (but which I’ve not done any homework on) are being confused with enzymatic byproducts.

Vinegar in Singapore is cheap especially the 1 SGD/- per litre bottles produced from rice bran. Green Dots uses these in numerous experiments. The cheap vinegar will be effective in glass cleaning, toilet bowls, stain removal on floors, etc just like housewives have known the deodorizing properties of sodium bicarbonate for a long time.

Since I recycle my organic kitchen waste into soups, food for my dog, vermiculture, composting in order of priority – have not felt a need to experiment with vinegar production at home – especially not at the cost of purchasing sugar or honey! However do think it makes a fabulously interesting experiment for children to do and learn from and test some hypotheses inhouse.

Kitchen waste recycled vis vermiculture or composting will undoubtedly have a lower carbon footprint than being deployed with sugar (its manufacture has its own carbon footprint) to produce vinegar and anaerobic gases including CO2 by yeast!

Here’s a link to some recent articles (Article 1 and 2) for producing enzymes and methane from organic waste. Pure cultures of specific fungi have also been used in fermentations to produce antibiotics.

Have known of a scientist from the National Chemical Laboratory (NCL) who was tinkering with more scientific composting methods and using lemon peels for effective pH management 20+ years ago. So also Gandhi’s nature cure ashram in Uruli Kanchan  has for last several decades been recycling organic wastes. Such methods that make local and contextual sense have been around for a long time in the world

The second one I received was from Lam Yuen Sean who’s a PhD student, and a volunteer with Ground – Up Initative, an urban gardening intiative by Tay Lai Hock in Singapore.

GE is definitely not well researched at present, so little technical information can be found about it.  More testing or literature reviews would be required to further support my preliminary views, and this account is by no means exhaustive and conclusive.

Ingredients:

The purpose of molasses or brown sugar is to provide “simple” carbon source or energy for the microorganisms to first feed and grow. When growth is sizeable, the microbes may then turn their attention to the additional food source (the waste materials) that is harder to digest due to the complexity in their molecular structures. This process is usually energy consuming for the microorganisms, and the added sugar may provide them the extra energy needed for this. The airtight container is necessary to promote fermentation (minimize oxygen), and biogases will be produced as by-products of the anaerobic breakdown of the sugars (usually hydrogen, CO2, and less likely methane). Thus, releasing the gases produced, especially during the initial stages, is essential.

Duration:

Can’t find the rationale for the stipulated “3 months”, but I guess this is based on past experiences. Definitely, longer durations would be more ideal to ensure a more complete fermentation process, where there will be none (or little) sugars left, and higher concentrations of products could be achieved. Also, the lack of food and the low pH levels would most likely kill/deactivate the microorganisms present (safer for handling).

Components:

Based on the preliminary test using gas chromatography, the major component of a newly prepared GE is acetic acid (in high concentrations), or “vinegar”. Slight ethanol (or “alcohol”) and propionic acid are also found in older GE samples. Do note that the machine used is calibrated to measure the presence and concentration of certain alcohols and fatty acids, and thus, may miss out several other important components (e.g., enzymes, sugars, amino acids, vitamins, etc.) that may also be present in the liquid. The pH measured for freshly prepared GE is ~4.4, and for the older sample is ~3.1, which will vary depending on the materials used.

Enzymes:

With regards to the enzymes present, it is rather difficult to comment, as I do not have the right equipment at hand. One of the comments made is somewhat true, in the sense that microorganisms possess intracellular enzymes within the cells that may not be easily dislodged into the solution. However, there are microorganisms that secrete extracellular enzymes into the external environment to allow the waste to be broken-down outside the cell. Also, the enzymes here may refer to the enzymes present in the waste material itself. For instance, pineapples and papayas are known to contain bromelain and papain enzymes used for tenderizing proteins, respectively. Therefore, the acidic condition and the fermentation process may allow such enzymes to be extracted from the waste materials into the solution.

Functions:

The high acetic acid concentration and low pH could be the main reasons for the many purposes of GE, as vinegar is well known to be used a cleaning agent, odor removal, preventing drain blockages, etc. Ethanol is known to have antiseptic properties, while propionic acid is used in food preservation. These substances may allow GE to act as an anti-microbial agent, insecticide and pesticide. When diluted, it could provide nutrients to plants due to the “growth hormones”, minerals, enzymes and/or other organic compounds extracted directly or converted from the waste materials. The highlight of GE is that it is organic and can be homemade at low costs, as compared to other products that contain synthetic chemicals (may be toxic to human health or environment) and consume high energy in their production.

Yeast:

On the contrary, please be careful of the white, black or brown layer formed on top of the liquid. Well, it could be yeast, as certain yeast prefers oxygen, thus forming a top layer in contact with the air in the container; but not all yeast strains are harmless. Similar to moonshine production, GE making involves the growth of the “unknowns”, so it is best not to have long direct contact/exposure with this layer or used for consumption purposes.

CO2 and methane:

Not much is being researched in terms of the CO2 production, but it is definitely there. Theoretically, aerobic processes would generate more CO2 than anaerobic processes, due to the more complete degradation of the carbon sources. Methane will only be produced in the presence of methanogens (certain kind of bacteria that are mostly found in swampy areas). Since the microorganisms present in GE are likely to be found naturally on the waste itself, airborne from the surrounding air, from the container or tap water added, chances of methane-forming bacteria to be present would be low.

Ozone:

This is surely more controversial. Ground-level ozone is known to be an air pollutant, causing adverse health effects, and should not be confused with the ozone layer in the upper atmosphere protecting us from the radiation. The low level ozone is generally formed from hydrocarbons and nitrogen oxides in the presence of sunlight. So, don’t think we are able to generate ozone through the fermentation of GE (shaded, and not much nitrogen oxides present); but if we do, it will be very scary… Therefore, those who claimed the benefits of ozone and its formation through GE should further substantiate their points.

EM:

Well, EM is a proprietary product used as a microorganism culture stock for various uses (e.g. composting), where the microorganisms present are known and well studied by the company. The use of EM will be useful in ensuring consistency between the different batches of GE, and since it is claimed to be non-pathogenic, GE practitioners should feel more relieved in terms of user health and safety. Not too sure on the cost and availability of EM in this region though.

Solid waste management:

Rather than to be disposed and incinerated, these waste materials can further serve additional purposes through GE, and subsequently be composted into organic fertilizer. This will surely help in preventing or reducing all forms of pollutions from the improper solid waste management and incineration, as well as to “close the waste loop” and promote recycling of waste back into the earth. Fruit and vegetable wastes are generated in huge amounts from both households and commercial/industrial sectors, and large-scale GE production would help to put these wastes into better uses.

Update to this article on 4th March 2011.

Based on the responses by readers and those whose opinions I have sought, I would advise readers to read the original blog entry below in the context of the next post:  ”Responses: How effective are Garbage Enzymes?” where I make the introduction based on feedback:

The sum and substance of the feedback is that Garbage Enzymes (the term itself may be a misnomer) can be used as a homemade vinegar for non-edible cleaning purposes. The efficacy of Garbage Enzymes as a fertiliser or pesticide or an air purifier is not yet verified by scientific research.  Even less obvious is its ability to lessen greenhouse gases. There are varying views on its contribution to waste management – in the local context, is composting a better way to manage waste, instead of adding molasses? Or can this be considered as one additional way to manage waste that would otherwise go to the incinerator?

The original article:

Garbage Enzymes are wonder home-made cleaners which double up as effective natural fertilisers and pesticides. They have the potential to revolutionise our kitchens by converting our kitchen waste into something truly restorative.

Who invented Garbage Enzymes (GE)?

I caught the garbage enzyme (GE) bug more than a year ago, when I learnt the fermenting process at Joyce Lye’s Kampung Senang Charity Foundation at Tampines, Singapore.

The formula was researched and popularised by the founder of the Organic Agriculture Association of Thailand,  Dr. Rosukon Poompanvong who won an FAO award in 2003 for her outstanding contribution to organic farming, through her work in using fermented organic waste as fertilizers, pesticides and livestock feed.

What are Garbage Enzymes?

GE is nothing but a vinegar or alcohol derived from fermenting fresh kitchen waste such as veggie and fruit dregs (peels, cuttings and bits), sugar (brown sugar, jaggery or molasses sugar) and water.

The enzyme is derived after one filters and removes the residue after 3 months. The key ingredient is molasses, which the bacteria and microorganisms present in the waste metabolise into alcohol. This is reduced in its final form to acetic acid or vinegar. Vinegar with its acidic properties is well known as an all-round non-toxic cleaner.

How to make Garbage Enzymes

Supplies needed:

Molasses, Jaggery or Brown Sugar

Fresh vegetable and/or Fruit peels ( dregs, peels and cuttings which are not cooked)

Air-tight plastic container

Measuring cup

Method:

1. In an airtight plastic container, measure and add

1 part molasses+ 3 parts veggie/fruit peels + 10 parts water

Example by weight:  Weight 100g molasses or brown sugar + 300 g of veggie/fruit peel + 1000g of water

Use any multiples thereof, maintaining the same ratio

2. Give the mixture a good shake, and screw on the lid tightly.

The whole process takes less than 5 minutes to make once you’re all set up with the ingredients and container, and the fermentation takes a minimum of 3 months, so it’s best to stagger the enzyme making in batches with labels on the container indicating the date they are made. This will ensure a regular supply later on.

Please note: You’d need to keep the container airtight. However you must open the lid once a week or once every few days to let out the gases, otherwise they may build up to explode in the container.

Here are some pictures of how the GE should look like during fermenting:

3. After 3 months, you can filter the residue to get a clear, dark brown liquid that has a fresh, sour smell like vinegar. (Shown in the picture above)

How to use Garbage Enzymes.

Garbage Enzymes are concentrated vinegars and work better when diluted with water. The required dilution ratios are provided below.

For Organic Gardening or Farming:

Here are guidelines for your garden/farm for use as natural fertilisers, insecticides, pesticides and as a plant growth hormone. For highly degraded soils, spraying continuously for 3 months can help restore soil quality.

Please use diluted solutions as tried and tested above – they work better in homoeopathic quantities and are more effective. Concentrated solutions can burn the plant or make the soil too acidic.

I’ve been using a combination of home-made compost, vermicastings, as well as garbage enzymes, so together they help nourish the soils of my organic garden at home.  However, I do know that at Tampines, Singapore Kampung Senang Charity Foundation exclusively uses GEs for their thriving community garden. They use GE once a week, by spraying the diluted solution (1:1000) on the leaves and the soil. The gardener likes to do this really early in the morning to facilitate better nutrient absorption.

For Household Use. Unlike for gardening, you can be more flexible with the dilution rates. Here are some suggestions:

Dos and Don’ts when making/using Garbage Enzymes

1. Use an airtight plastic container, and not metal or glass ones which can’t expand as gases build up within the container, and may explode.  Even with the plastic container, it’s important to open the lid once a week or once every few days during the first month and stir.
2. Store the container in a dry and cool area away from direct sunlight. Keep the GE at room temperature and don’t store inside a refrigerator.
3. Use any combination of fresh veggie or fruit peels or dregs. I personally prefer a combination of pineapple, papaya and citrus peels. Do not use cooked food, meat or fish, or other non-food items like paper, metal, glass, plastic and so on.
4. Don’t worry about the white, black or brown substance that forms as a layer on top of the enzyme.  The white layer is yeast that is rich in Vitamin B complex and Vitamin C and can actually be used for making bread or roti
5. If you see worms, add an extra ratio sugar and cover air tight. They will disappear by themselves.
6. You may filter out the residue after 3 months using a sieve or even and cotton cloth or T-shirt. If you can wait for 6 months, it’s even better.  There is no expiry date for the GEs once filtered.
7. Reuse the residue, as a fertiliser in the garden by drying and mixing with the soil, or combining it with fresh veggie/fruit dregs as a starter for a new GE batch.
8. Dilute the GE with water for most uses. This increases its effectiveness. Dilution is especially important when using as fertilisers or pesticides for plants, where high concentrations can prove too acidic for them.

Making GEs will keep tons of kitchen waste from landfills and incinerators, including the plastic bags that are needed to bag them. Think of how much CO2 emitting fossil fuels can be avoided that would otherwise be used in making, packaging and transporting toxic cleaners, fertilisers, insecticides and pesticides.

Using GEs improves indoor air quality and promotes organic gardening or farming which will help generations to come, in terms of health and healthy soils.

Hope you’ll join me in fermenting and spreading the Garbage Enzyme revolution!

I bring this up because of an email I received today about the harmful effects of Sodium Lauryl Sulphate (SLS) or its variant, Sodium Laureth Sulphate (SLES), which are ingredients that lead to the “foaming” action in most personal care and home cleaning products. SLS is used as a surfactant in floor cleaners, car washes, carpet cleaners, stain removers, laundry detergents, dishwashing liquids and fabric glues. You might like to know that it’s also added to products such as toothpastes, shampoos, soaps, shaving creams, moisturisers and sun-creams.
 
Just think about it, if SLS can remove the car grease in the engines or stains in your carpets, it could have a similar abrasive and drying effect on your teeth, scalp and skin.

In fact, according to the JOURNAL OF THE AMERICAN COLLEGE OF TOXICOLOGY, “In absorption, metabolism and excretion studies, Sodium Lauryl Sulfate had a degenerative effect on the cell membranes because of its protein denaturing properties. High levels of skin penetration may occur at even low use concentration. Other studies have indicated that Sodium Lauryl Sulfate enters and maintains residual levels in the heart, the liver, the lungs and the brain from skin contact. This poses question of it being a serious potential health threat to its use in shampoos, cleansers, and tooth pastes.”

A good EcoWALK habit would be to read the various labels on everything you buy, and stay away from products which have a long list of chemicals, especially SLS. That’d be good for your skin and gums, and good for the planet, which could do with a lot less than the 100,000 or so synthetic chemicals that are lingering around. 

Some brands which you may find are SLS free are Dr. Bronner’s, Nature’s Gate, some products from Tom’s of Maine.  Of course, these products tend to be pricey. If you’re comfortable using toothpowder, there’s an Ayurvedic brand from Vicco Vajradanti.  However, their toothpaste does contain SLS, despite its claim of being “herbal.” So, watch out for the greenwash.

You could try some simple effective home made alternatives, which are light on your pocket too.

Home made toothpaste:

Here’s a recipe I simplified from www.crazy-mumma.blogspot.com
3 tbs baking soda (bi-carb soda)
1/2 tsp salt
2 tbs glycerine
20-30 drops peppermint extract or essential oil, like tea tree for example.

Mix the bi carb soda and salt thoroughly, then add the glycerine to form a paste. Add the peppermint or other essential oil and combine well. Store in an airtight container.

Home made shampoo:
The plain old baking powder(bicarbonate of soda) is such a handy ingredient!  Instead of shampoo, try a tablespoon baking powder with a cup of warm water to rinse your hair. If you have dandruff, then regular use of apple cedar vinegar is a good cure. Add a tablespoon of apple cedar vinegar to a cup of warm water. Apply in your hair and allow to soak for a few minutes and then rinse off.

As for my great-grandma…the secret to her gleaming white smile was a regular brushing of the teeth with the twig of Neem (Azadirachta indica). Neem is well known to have anti-bacterial properties, its fibres cleanse the teeth, and its juice works as a mouth freshener too. Now, that’s better than SLS, on any EcoWALKing day!
