TRIHYDROXYSTEARIN

Description

Trihydroxystearin, also known as trihydroxystearin, is a multifunctional cosmetic ingredient derived from hydrogenated castor oil. This white, waxy solid is primarily used as an emollient, thickening agent, and texture enhancer in various skincare and cosmetic formulations. Its molecular structure consists of a glycerol backbone attached to three hydroxystearic acid chains, providing unique properties that benefit product stability and skin feel.

In skincare formulations, trihydroxystearin acts as an effective emollient, helping to soften and smooth the skin's surface. It forms a protective barrier that reduces transepidermal water loss, thereby improving skin hydration. As a thickening agent, it contributes to the desired viscosity and texture of creams, lotions, and other cosmetic products. Trihydroxystearin also exhibits excellent stability across a wide pH range and is compatible with most cosmetic ingredients.

This versatile compound is particularly valuable in anhydrous formulations, such as lipsticks and solid balms, where it helps to stabilize oils and improve product structure. Its low comedogenicity makes it suitable for use in facial products, including those designed for acne-prone skin. Trihydroxystearin is generally considered safe for topical use and is approved by regulatory bodies worldwide.
