OLETH-35.

Valuable CAS 9004-98-2 / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

OLETH-35 is a polyethylene glycol ether of oleyl alcohol, primarily serving as a versatile emulsifier and surfactant in cosmetic formulations. It plays a critical role in stabilizing oil-in-water mixtures and facilitating effective cleansing.

Emulsifying Surfactant / Cleansing

Science

This ingredient functions by significantly lowering the surface tension of liquids, allowing oil and water to combine into stable emulsions that would otherwise separate. As a surfactant, OLETH-35 aids in solubilizing various compounds and enhances the cleansing action of products by helping to lift and suspend impurities for removal.
