Ammonium Lauryl Sulfate
The U.S. Food and Drug Administration (FDA) includes sodium lauryl sulfate on its list of multipurpose additives allowed to be directly added to food. Sodium lauryl sulfate and ammonium lauryl sulfate are also approved indirect food additives. For example, both ingredients are permitted to be used as components of coatings.
The safety of sodium lauryl sulfate and ammonium lauryl sulfate has been assessed by the Expert Panel for Cosmetic Ingredient Safety on two separate occasions (1983 and 2002), concluding each time that the data showed these ingredients were safe in formulations designed for brief, discontinuous use, followed by thorough rinsing from the surface of the skin. In products intended for prolonged contact with skin, concentrations should not exceed 1%.
Sodium lauryl sulfate and ammonium lauryl sulfate may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Regulation of the European Union.
Is there any truth to the Internet rumors about sodium lauryl sulfate?
Since 1998, a story has been circulating on the Internet that states that sodium lauryl sulfate can cause cancer. This allegation is unsubstantiated and false. In fact, in a 2002 safety review, the Expert Panel assessed all of the data on sodium lauryl sulfate and concluded that “[n]one of the data suggested any possibility that sodium lauryl sulfate or ammonium lauryl sulfate could be carcinogenic. Despite suggestions to the contrary on the Internet, the carcinogenicity of these ingredients is only a rumor.”
