TRIHYDROXYSTEARIN.

Valuable CAS 139-44-6 / SKIN CONDITIONING, VISCOSITY CONTROLLING

Trihydroxystearin is a triglyceride derived from 12-hydroxystearic acid, recognized for its exceptional performance as a rheology modifier and gelling agent. It is utilized to precisely control the texture and stability of cosmetic emulsions and anhydrous formulations.

Viscosity controlling Emollient Skin-conditioning agent - occlusive

Science

This ingredient functions by forming a reversible, three-dimensional network within the formulation, which effectively increases viscosity and provides shear-thinning properties. On skin, its role is primarily indirect: it stabilizes the product vehicle, ensuring optimal and uniform delivery of active ingredients, while contributing a smooth, elegant sensorial feel due to its emollient properties.
