Laureth-7 is a synthetic ingredient derived from lauryl alcohol, a non-drying fatty alcohol obtained from coconut oil. It functions as an emulsifier and surfactant in skincare formulas, helping to blend different ingredients and cleanse the skin. It has a proven track record of safety in cosmetic use, with a CIR rating of safe for use in cosmetics with some qualifications.

Laureth-7 is available in natural or synthetic form, with both types being effective. The lower the laureth’s numerical value, the lower the viscosity. Laureth-7 is used as an emulsifier and surfactant in many different cosmetics and personal care products, including cream rinses, conditioners, bath oils, creams, lotions, deodorants, and shaving products. Laureth-7 is obtained by the extensive chemical modification of Lauric Acid, a natural fatty acid, and Oxirane. The CIR expert panel has conducted research on two (Laureth-4 and Laureth-23) of the many Laureths and made an inclusive approval of all Laureths, including Laureth-7, for the use in cosmetics. However, small amounts of 1,4-dioxane, a by-product of ethoxylation, may be found in the Laureth ingredients, and the potential presence of it can be controlled through purification steps to remove it before blending Laureth-7 into cosmetic formulations. Sodium lauryl sulfate (SLS) is a surfactant that is used in many cleaning and beauty products. It is safe for use in concentrations of one percent or less on the skin. SLS can cause skin irritation in some people, but it is not a carcinogen. SLS is also used as a food additive, usually as an emulsifier or a thickener.
