Top 10 Reasons to Avoid Sodium Lauryl Sulfate

Here are our top ten reasons you should not use anything containing SLS.

1. It is a known skin irritant. When cosmetic companies need to test the healing properties of a lotion, they need toirritate the skin first. What do they use to do this? SLS, of course. If you have dandruff, dermatitis, canker sores, or other irritated tissues or skin, it could be due to SLS.

2. It pollutes our groundwater.  It is toxic to fish and other aquatic animals and has the potential for bioaccumulation (meaning it accumulates in the bodies of the fish.)  It also is undetected in many municipal water filters, getting into the tap water that you drink.

3. It is actually a pesticide and herbicide.  It is commonly used to kill plants and insects. Makers of SLS recently petitioned to have SLS listed as an approved pesticide for organic farming.  The application was denied because of its polluting properties and environmental damage.

4. It emits toxic fumes when heated. Toxic Sodium Oxides and Sulfur Oxides are released when SLS is heated.  Makes a hot shower with an SLS shampoo seem not quite as nice…

5.  It has corrosive properties.  According to the American College of Toxicitythis includes corrosion of the fats and protiens that make up skin and muscle.  SLS can be found in garage floor cleanrs, engine degreasers, and car wash soaps.

6.  Long-term permeation of the body’s tissues.
 A study from the University of Georgia Medicine showed that SLS had the power to permeate the eyes, brain, heart, and liver.

7.  It’s an eye irritant.  It was shown to cause cataracts in adults, and is proven to inhibit the proper formation of eyes in small children.

8.  Nitrate and other solvent contamination.  Toxic solvents, including carcinogenic nitrates are used in the manufacturing of SLS, traces of which can remain in the product.

9.  Manufacturing process is highly polluting, emitting cancer-causing volatile organic compounds, sulfur compounds, and air particulates.

10.  It helps other chemicals get into your body.  
SLS is a penetration enhancer, meaning that its molecules are so small they’re able to cross the membranes of your body’s cells.  Once cells are compromised, they become more vulnerable to other toxic chemicals that may be with the SLS.

Does it cause cancer?
SLS is not a recognized carcinogen itself, but there is some truth behind those internet rumors.  When SLS is mixed with triethanolamine (or T.E.A) carcinogenic substances called nitrosames can form and be released.

Cocamidopropyl betaine.


Cocamidopropyl betaine (CAPB) is an amphoteric synthetic detergent that has been increasingly used in cosmetics and personal hygiene products (eg, shampoos, contact lens solutions, toothpaste detergents, makeup removers, bath gels, skin care products, cleansers, liquid soaps, antiseptics, and gynecologic and anal hygiene products) because it induces relatively mild skin irritation. Delayed T-cell-mediated type IV hypersensitivity reactions to CAPB have been reported, and contact sensitization prevalence is estimated at between 3.0 and 7.2%. The increasing rates of sensitization led to CAPB’s being named Allergen of the Year in 2004. Related impurities rendered during the manufacturing process (such as amidoamine and dimethylaminopropylamine) are thought to play a role in sensitization.

1. Shampoos may contain carcinogens.

One of them is Cocamide DEA. The State of California added it to the list of chemicals known to the State to cause cancer in June 2012. Cocamide DEA is what makes shampoo produce rich foam, which is appealing to a lot of people.

By the way, Cocamide DEA is produced from coconut oil. But there are a few chemical reactions and toxic chemicals involved in the process, which makes the final product resemble coconut oil in no way, shape or form. So next time you hear that the ingredient is made from coconut oil, do not make the assumptions of safety quickly.

The good news is that under the pressure of a lawsuit, 26 companies are stopping using Cocamide DEA. The bad news is that sometimes ingredients are not properly disclosed or substituted with something as toxic but less notorious.

What is Glycol Distearate?

A close relative to glycol stearate and glycol stearate SE, glycol distearate is a white to cream-colored waxy solid used to condition skin, to increase the thickness of certain cosmetic products (like creams and lotions), and to reduce the clear or transparent appearance of cosmetics, such as in make-up concealers. Glycol distearate in particular is often used as a “pearlizing” agent in body washes, to give the formula that pearlescent look that seems so inviting.

What most people don’t like about this ingredient is that it’s made from ethylene glycol, which is used to make antifreeze, de-icing solutions for cars and planes, hydraulic brake fluids, lacquers, resins, wood stains, synthetic waxes, and the like. Though small amounts aren’t likely to harm your health, it’s still doesn’t seem like putting a chemical like this (mixed with animal or vegetable fat) will benefit your skin, does it?



DMDM hydantoin is an antimicrobial formaldehyde releaser preservative. People exposed to such formaldehyde-releasing ingredients may develop a formaldehyde allergy or an allergy to the ingredient itself and its decomposition products. In the U.S., approximately 20% of cosmetics and personal care products contain a formaldehyde-releaser and the frequency of contact allergy to these ingredients is much higher among Americans compared to studies in Europe.

About METHYLCHLOROISOTHIAZOLINONE: Methylchloroisothiazolinone is a widely-used preservative; has been associated with allergic reactions.

Butylphenyl Methylpropional is a synthetic fragrance compound that is used in cosmetics. It is also known as p-tert-butyl-alpha-methylhydrocinnamic aldehyde, a colorless liquid with a strong floral scent.

“it didn’t really work very well for me. I gave it a three star because I must admit that the shampoo has a very cleansing effect, and the first time I used it with the conditioner I was completely wowed by the soft, fluffy, silkiness of my hair afterwards. But my hair was very short and damaged by the time I got around to purchasing this product and the formula is so strong that it really dried out my hair—it felt sort of like horse hair, quite literally. I was not using a second moisturizing conditioning treatment though, and its possible that if I had I would have enjoyed better results. It did not seem to make very hair grow very fast” by AClare
