CIR Safety Review: The CIR Expert Panel previously reviewed the safety of Ammonium Laureth Sulfate, Sodium Laureth Sulfate and Sodium Myreth Sulfate and determined that the information on these ingredients also supported the safety of Ammonium Capryleth Sulfate, Ammonium Pareth-25 Sulfate, Ammonium Myreth Sulfate, Magnesium Coceth Sulfate, Magnesium Laureth Sulfate, Magnesium Myreth Sulfate, Magnesium Oleth Sulfate, Sodium Coceth Sulfate, Sodium C10-15 Pareth Sulfate, Sodium C12-13 Pareth Sulfate, Sodium C12-15 Pareth Sulfate, Sodium Deceth Sulfate, Sodium Laneth Sulfate, Sodium Oleth Sulfate, Sodium Trideceth Sulfate and Zinc Coceth Sulfate. The CIR Expert Panel noted that irritation may occur for some people who use personal care products containing these ingredients. The irritant effects were similar to those produced by other detergents, and the severity of the irritation appeared to increase directly with concentration. Sodium and Ammonium Laureth Sulfate did not result in adverse effects in a number of safety studies including acute, subchronic and chronic oral exposure, reproductive and developmental toxicity, carcinogenicity and photosensitization studies.

The CIR Expert Panel concluded that Ammonium Capryleth Sulfate, Ammonium Pareth-25 Sulfate, Ammonium Laureth Sulfate, Ammonium Myreth Sulfate, Magnesium Coceth Sulfate, Magnesium Laureth Sulfate, Magnesium Myreth Sulfate, Magnesium Oleth Sulfate, Sodium Coceth Sulfate, Sodium C10-15 Pareth Sulfate, Sodium C12-13 Pareth Sulfate, Sodium C12-15 Pareth Sulfate, Sodium Deceth Sulfate, Sodium Laneth Sulfate, Sodium Laureth Sulfate, Sodium Myreth Sulfate, Sodium Oleth Sulfate, Sodium Trideceth Sulfate and Zinc Coceth Sulfate were safe for use in cosmetics and personal care products in the present practices of use and concentration when formulated to be non-irritating.

Trace amounts of 1,4-dioxane, a by-product of ethoxylation may be found in these salts of sulfated ethoxylated fatty alcohols. The potential presence of 1,4-dioxane is well known and can be controlled through purification steps to minimize it from the ingredients before blending into cosmetic formulations.

Alkyl ether sulfates are esters and therefore, are subject to hydrolysis, especially at extreme pH values. These ingredients are more water soluble than the corresponding alkyl sulfates. They function as surfactants acting as cleansing and emulsifying agents.
