CETRIMONIUM DIMETHICONE PEG-8 OLIVATE/SUCCINATE.

Valuable CAS - / HAIR CONDITIONING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

A sophisticated, multifunctional conditioning agent that merges the silkiness of olive-derived esters with a protective quaternized silicone complex. It is specifically engineered to neutralize the irritation potential of cleansing systems while leaving a weightless, emollient finish on the skin.

Science

This ingredient utilizes its cationic (positively charged) nature to bind substantively to the skin's negatively charged surface. Once attached, it forms a breathable, protective film that mimics natural lipids, effectively locking in moisture and shielding the epidermis from the stripping effects of harsh surfactants.
