C12-13 PARETH-7 CARBOXYLIC ACID.

Valuable / CLEANSING, SURFACTANT - CLEANSING

A mild anionic surfactant engineered with ethylene oxide groups that provide exceptional gentleness compared to traditional sulfate cleansers. Beyond cleansing, this multifunctional ingredient serves as an effective solubilizer for UV filters and fragrances in water-based formulations.

Science

Functions as an anionic surfactant that reduces water's surface tension to lift oils and impurities from skin. The seven ethylene oxide units create a 'cushioning' effect by enlarging the hydrophilic head group, significantly reducing skin barrier penetration and irritation potential compared to harsh sulfates like SLS.
