TRIMETHYLOLPROPANE TRISTEARATE

Description

Trimethylolpropane Tristearate is a versatile synthetic ester widely used in cosmetic and personal care formulations. This white, waxy solid is derived from trimethylolpropane and stearic acid, resulting in a compound with excellent emollient and thickening properties. Its primary function is to enhance the texture and stability of various skincare and makeup products.

In skincare formulations, Trimethylolpropane Tristearate acts as an effective emollient, helping to soften and smooth the skin's surface. It forms a protective barrier that reduces transepidermal water loss, thus contributing to improved skin hydration. The ingredient's thickening properties make it valuable for creating stable emulsions and enhancing the viscosity of creams, lotions, and balms.

Trimethylolpropane Tristearate is particularly beneficial in lip products, such as lipsticks and lip balms, where it imparts a smooth, creamy texture and improves product adherence to the lips. In sun care formulations, it aids in creating water-resistant products by forming a film on the skin's surface.

This ingredient is generally considered safe for topical use and is compatible with a wide range of cosmetic ingredients. Its low comedogenicity makes it suitable for use in products designed for acne-prone skin.
