SODIUM DIHYDROXYCETYL PHOSPHATE.

Valuable CAS 94277-32-4 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Sodium Dihydroxycetyl Phosphate is a multifunctional ingredient primarily recognized for its role as an emulsifier and surfactant in skincare. It facilitates the harmonious blending of disparate components like oils and water, thereby creating smooth, consistent textures. Beyond its primary function, it also offers moisturizing and skin-soothing benefits for an enhanced sensorial experience.

Summary

emulsifying surfactant moisturizing skin-soothing

Science

Mechanism of Action

This ingredient operates by leveraging its amphiphilic molecular structure, which possesses both lipophilic (oil-attracting) and hydrophilic (water-attracting) segments. This dual affinity enables it to effectively reduce the interfacial tension between incompatible liquids, stabilizing and thickening cosmetic formulations. Furthermore, its presence contributes to enhanced skin hydration and a calming effect, promoting a soft and supple skin feel.
