Insufficient Data CAS - / HAIR CONDITIONING

A sophisticated, amphoteric silicone-surfactant hybrid designed to provide targeted conditioning and surface smoothing. It functions as both a skin-softening agent and a specialized emulsifier, delivering a refined, silky texture to aqueous formulations.

Skin conditioning Hair conditioning Emulsifying Surfactant

Science

This ingredient operates via an amphoteric structure that allows it to selectively bond to localized areas, creating a breathable, conditioning film. On the skin, it acts as a lubricant and emollient, reducing friction and enhancing softness, while its surfactant properties help stabilize water-in-oil emulsions.
