Trihydroxystearin, often used in the cosmetics industry, is an ester derived from glycerin and stearic acid. Being a emollient and thickening agent, it offers important benefits to a wide range of cosmetic products. For instance, in lipsticks and lip balms, Trihydroxystearin provides a smooth application and improves the product’s overall performance by retaining moisture and preventing drying. Additionally, in skincare products, it contributes to a creamy texture and helps maintain skin hydration. Despite its complex name, Trihydroxystearin is a key ingredient that enhances the user experience by providing better texture, application, and hydration benefits in cosmetic products.
