Sodium Laurel Sulfate or Sodium Dodecyl (SLS, SLSF)

Industrial Uses:  Harsh Floor Cleaners, Engine Degreasers, Car Wash Detergents, Laundry Detergents

Personal Care Products:  Toothpaste, Shampoos, Body Gels, Bubble Baths, Facial Cleansers, Baby Wipes, Baby Shampoos, Bubble Baths, Liquid Hand Soaps and Body Gels, Sunblock, Cosmetic Products

Purpose:  Inexpensive, Makes Foam, Thickens with Salt, found in 90% of commercial shampoos even many so called “natural products”.  It is very important to read a products ingredients prior to purchase.

SLS Toxicity and Cancer:

A serious health concern with SLS is its tendency to react with other ingredients to form NDEA, a nitrosamine and potent carcinogen.  According to a 1978 FDA report, shampooing the hair with a product contaminated with this nitrosamine can lead to its absorption into the body at levels much higher than eating nitrate-contaminated foods. (Researchers estimate the nitrate absorption from one shampoo is equal to eating a pound of bacon.)  The FDA has recently warned shampoo manufacturers of unacceptable levels of dioxin formation in products containing sodium laurel sulfates SLFS (dioxins are also dangerous carcinogenic compounds).  Only laboratory testing can determine if a shampoo is contaminated with these powerful carcinogenic compounds.  .http://www.seektheanswer.com/dangerous_beauty.htm

Damage to Your Skin:

Researchers have known for years that SLS is a skin irritant.  SLS is used as a laboratory standard for irritating skin and inducing contact dermatitis.  SLS is useful to lab testing “because of its ability to penetrate and impair the skin barrier.”  SLS damages the skin barrier functions, enhances allergic response to other toxins and allergens, damages and alters skin cells, causes substantial roughness to the skin, results in severe modification of skin recombinant structure.

SLS is listed as toxic to skin in many studies.  In patients with seborrhea and eczema, SLS increases irritant reactions and susceptibility.  SLS is indicated in migration of Langerhans cells to regional lymph sites in contact dermatitis, explaining lymph node inflammation in some cases. A systemic response is clearly evident.  Research also found that fair skin is more susceptible to SLS irritations, as is skin with existing eczema even where the eczema is not local to the SLS contact.http://www.seektheanswer.com/dangerous_beauty.htm.

SLS and Eye Damage in Young Children:

“The greatest concern of many scientists is SLS, it has been shown to damage protein formation in eye tissue in young animals, raising serious concerns about the possibility of ocular tissue malformation, blindness in infants and young children.  In animal studies, SLS penetration and uptake is much greater in neonatal and young animal eye tissue, compared to adult animals, showing “penetration into the eye, as well as systemic tissues (brain, heart, liver, etc.)”  SLS also showed long-term retention in tissues, up to 5 days after a single drop”

“Researcher Keith Green, Ph.D., D. Sc., of the Medical College of Georgia, also reports that SLS extends the healing of corneal tissue by a factor of 5, from 2 days (normal) to more than 10 days.  He also has concerns about cataract formation from SLS.  Writing for Research to prevent blindness, Inc., Dr. Green states in part: “ There is immediate concern relating to the penetration of these chemicals into the eye and other tissues.  This is especially important in infants…exposure to SLS results in accumulation in eye tissues, a process that could retard healing and possible have long-term effects.”  He concludes that exposure to SLS causes improper eye development in children and that since SLS is absorbed systemically through the skin, it doesn’t have to enter the eye directly.

SLS and Premature Hair Loss:

SLS is implicated in premature hair loss in men and women, and may be one reason for wide-spread incidence of thinning hair.  Because SLS is such a caustic cleanser, it actually corrodes the hair follicle and impairs its ability to grow hair.  SLES (Sodium Laurel Ether Sulfate) causes dramatic decline in the hair growth cycle, and prolongs the hair loss phase (normally 3 months) by a factor of eight.  Simply removing this ingredient, and its corrosive and irritating effects, begins to restore the natural, healthy function of the follicle.

SLS is also implicated in scalp irritation, eczema, dandruff, and other scalp conditions.  Many shampoos designed to alleviate dandruff, itching, and other scalp disorders may actually be causing the toxicity of SLS-containing formulas to the skin and scalp.  Avoiding contact with this cytotoxic (cell-killing) chemical is all that many people require to completely alleviate scalp disorders.
