Ammonium Laureth Sulfate

What Is It?

Ethoxylated Alcohol salts are ingredients used primarily in cleansing products, including bubble baths, bath soaps and shampoos.  Examples include 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 Myreth Sulfate, Sodium Oleth Sulfate, Sodium Trideceth Sulfate and Zinc Coceth Sulfate.

Why is it used in cosmetics and personal care products?

Most of the ingredients function as surfactants and are used as cleansing agents. They clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away. Others – specifically, Magnesium Coceth Sulfate, Sodium Coceth Sulfate, Sodium Myreth Sulfate, Sodium Trideceth Sulfate and Zinc Coceth Sulfate – also exhibit emulsifying properties. Sodium Laneth Sulfate is reported to additionally act as a skin conditioning agent.

Safety Information:

In 2010, the Cosmetic Ingredient Review (CIR) Expert Panel evaluated the scientific data for these ingredients and the closely related sodium laureth sulfate and ammonium laureth sulfate and concluded that all of these ingredients were safe for use in cosmetics and personal care products in the present practices of use and concentration, when formulated to be non-irritating.

More safety Information:

Trace amounts of a manufacturing by-product called 1,4-dioxane may be found in these ingredients .  The compound 1,4-dioxane is not used as an ingredient in cosmetic or personal care products.  It is a manufacturing by-product that may be present in extremely small amounts in some cosmetic and personal care product ingredients. These ingredients include certain cleansing materials (i.e., detergents), foaming agents, emulsifiers and solvents that are included on this page.The U.S. Food and Drug Administration (FDA) states on its website that, “The 1,4-dioxane levels we have seen in our monitoring of cosmetics do not present a hazard to consumers.”These cleansing ingredients may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Directive of the European Union. Ingredients of animal origin must comply with European Union animal by-products regulations.
