HEALTH CONCERNS
Is this chemical a carcinogen?	No
How can it affect me?	The Occupational Safety and Health Administration (OSHA), the National Toxicology Program (NTP) and the International Agency for Research on Cancer (IARC) have all rated sodium lauryl sulfate as being non-carcinogenic. However, it is considered to be an irritant and known to pose some health risks. Sodium lauryl sulfate may worsen skin problems in individuals with chronic skin hypersensitivity, with some people being affected more than others. Sodium lauryl sulfate has also been shown to irritate the skin of the face with prolonged and constant exposure (more than an hour) in young adults. The Cosmetic, Toiletry, and Fragrance Association (CTFA), now known as the Personal Care Products Counsel, discourages use of sodium lauryl sulfate in products intended for prolonged use, unless in low concentrations. A shampoo containing 15% of sodium lauryl sulfate is tolerable only because it comes in contact with the scalp just for a few minutes and is diluted with water while in use. If you get it in your eyes, it is recommended that you rinse well. The U.S. Food and Drug Administration (FDA) requires that fluoride toothpastes carry a warning label about the dangers of swallowing too much toothpaste and sodium lauryl sulfate is one of the three ingredients (along with sorbitol and fluoride) identified by posing a health risk, such as diarrhea, not cancer. Sodium lauryl sulfate in toothpaste may cause aphthous ulcers, commonly referred to in some countries as canker sores.
Are there controversial issues?	No
