AMMONIUM C12-15 PARETH SULFATE.

Optional CAS 125301-89-5 / CLEANSING

An ethoxylated anionic surfactant that provides cleansing and foaming action in skincare formulations. This ingredient combines a hydrophobic alkyl chain (C12-15) with a hydrophilic ethoxylated sulfate head to effectively remove oils and impurities from the skin surface.

Summary
