News / sodium lauryl sulfate
A common ingredient in personal care products is raising health questions for researchers in the United States, Germany, Switzerland, and Japan--namely sodium lauryl sulfate, also known as sodium dodecyl sulfate (SDS), sodium laureth sulfate (SLES), and sodium laurel sulfate (SLS).
Present in numerous commercial shampoos, sodium lauryl sulfate is a detergent researchers have known for years as a skin irritant. It also has a tendency to react with other ingredients to form NDELA, a potent carcinogen, that when used in shampoo can lead to its absorption into the body.
SLS damages skin barrier function, enhancing allergic response to other toxins and allergens. It also damages and alters skin cells, increasing irritant reactions in all skin types, but particularly those with seborrhea, eczema and fair skin. It may be responsible for the widespread incidence of thinning hair and hair loss in men and women. Caustic SLS corrodes the hair follicle, causing significant decline in hair growth.
