3-Hydroxy-2,2-bis(hydroxymethyl)propyl octadecanoate

Description:

3-Hydroxy-2,2-bis(hydroxymethyl)propyl octadecanoate, commonly known as glyceryl stearate, is an ester derived from glycerol and stearic acid. This compound is characterized by its emollient and emulsifying properties, making it widely used in cosmetic and pharmaceutical formulations. It appears as a white to pale yellow waxy solid or semi-solid at room temperature and is soluble in oils but only slightly soluble in water. The presence of hydroxyl groups contributes to its ability to form stable emulsions, enhancing the texture and stability of creams and lotions. Additionally, glyceryl stearate is known for its skin-conditioning effects, providing a smooth and soft feel upon application. It is generally regarded as safe for use in personal care products, although individuals with sensitive skin should perform a patch test. Its applications extend beyond cosmetics to food and industrial products, where it serves as a thickening agent and stabilizer. Overall, glyceryl stearate is valued for its multifunctional role in enhancing product performance and user experience.
