This inexpensive detergent is commonly used in cosmetic

> degreasers, car-wash soaps, etc. It is very corrosive and
> readily attacks greasy surfaces.
>
> Sodium lauryl sulfate is used throughout the world for
> clinical testing as a primary skin irritant. Laboratories
> use it to irritate skin on test animals and humans so that
> they may then test healing agents to see how effective they
> are on the irritated skin.

> A study at the University of Georgia Medical College,
> indicated that SLS penetrated into the eyes as well as
> brain, heart, liver, etc., and showed long-term retention

> Is potentially harmful to skin and hair. Cleans by

> Another extremely serious problem is the connection of SLS
> with nitrate contamination. SLS reacts with many types of
> ingredients used in skin products and forms nitrosomines
> (nitrates). Nitrates are potential cancer-causing
> carcinogenics.
>
> Because of the alarming penetrating power of SLS, large
> amounts of these known carcinogens are absorbed through the
> skin into the body. A variation of SLS is SODIUM LAURETH
> SULFATE (Sodium Lauryl Ether Sulfate- SLES). It exhibits
> many of the same characteristics and is a higher-foaming
> variation of SLS.
