CAPROYL ETHYL GLUCOSIDE.

Valuable CAS 146599-18-0 / CLEANSING, SURFACTANT - CLEANSING

A sophisticated, plant-derived non-ionic surfactant and hydrotrope engineered to bridge the gap between aqueous and lipophilic phases. It serves as a high-performance solubilizer and antimicrobial booster, ensuring formulas remain stable and biologically protected without compromising skin barrier integrity.

Surfactant Cleansing Agent Solubilizer Preservative Booster Hydrotrope

Science

This short-chain (C6) alkyl glucoside functions by significantly lowering interfacial tension to facilitate stable micellar structures. Beyond its role as a mild cleanser, its unique molecular architecture allows it to increase the permeability of microbial cell walls, thereby synergistically amplifying the efficacy of co-preservatives while effectively dispersing hydrophobic actives like UV filters and fragrances.
