  • Applications

    2-Monostearin is commonly used as an emulsifier and texturizing agent in foods, helping to stabilize oil-water mixtures and improve product texture. In cosmetics and personal care, it serves as an emollient, thickener, and processing aid, contributing to cream stability and slip. In pharmaceuticals, it is used as an excipient and emulsifier/stabilizer. In industrial manufacturing, it acts as a plasticizer and processing aid for polymers. In coatings and inks, it functions as a surfactant and dispersing/emulsifying agent to improve pigment dispersion and film formation. In cleaning and detergents, it can serve as a nonionic surfactant or co-emulsifier. Applications vary with local regulations and formulation limits.
