Sodium Lauryl/Laureth sulfate

According to Wikipedia, Sodium lauryl sulfate is a detergent and surfactant found in many personal care products like soaps, shampoos, toothpaste. It is an inexpensive and very effective foaming agent. It removes oils from the skin, and can cause skin and eye irritation. Toxicology research by the US OSHA, NTP, and IARC supports the conclusions of the Cosmetic, Toiletry, and Fragrance Association and the American Cancer Society that SLES is not a carcinogen. It also represents a potentially effective topical microbicide, which can also inhibit and possibly prevent infection by various enveloped ad non-enveloped viruses such as Herpes simples viruses, HIV. SLS is not carcinogenic when either applied directly to skin or consumed. It has been shown to irritate the skin of the face with prolonged and constant exposure (more than an hour) in young adults.

In my opinion, and according to my research, I believe that SLS is not a carcinogen. It may be a skin irritant if you are exposed to this chemical to your skin for a prolonged time. Food and drug administration will not allow this chemical to be included in our daily hygiene products if it could harm us. After this research, I learned that this chemical is used for detergents also. Obviously, you do not want to use the same strength of a substance on your hair or skin as you would on the floor. Typically, they will not put too much SLS in our shampoos, soaps, or toothpaste. For sure, this was diluted in water. I believe that this is not harmful. Just a piece of advice, when using shampoos, soaps, or anything you apply in your skin, always dilute it to water. Nothing is harmful in a little amount. Too much will do, too much will kill you. :) We are surrounded by a lot of chemicals, environmentally or inside our system.
