Overview

Laureth-4 is a nonionic, ethyoxylated surfactant based on lauryl alcohol.

This surfactant is useful as an emulsifier, where it is employed to create oil-in-water emulsions. An oil-in-water emulsion is a mixture of oil and water in which oil droplets are suspended throughout a continuous water phase. These emulsions tend to be lightweight and refreshing upon application.

Laureth-4 is supplied as a clear liquid and also serves to solubilize oil into water. A solubilizer is a type of ingredient that can disperse and suspend small amounts of oil into water and maintain product clarity. The oils are typically fragrances or other oils added in small amounts.
