Sorbitan sesquioleate (Cat No.: M013431) is a nonionic surfactant and emulsifier derived from sorbitol and oleic acid. It consists of sorbitan (a sorbitol derivative) esterified with approximately 1.5 moles of oleic acid. Commonly used in cosmetics, pharmaceuticals, and personal care products, it stabilizes oil-in-water emulsions and enhances the texture and spreadability of formulations. Its mildness and compatibility with skin make it suitable for lotions, creams, and ointments. Sorbitan sesquioleate also functions as a dispersing agent for pigments and active ingredients.
