Description

Sorbitan, Mono(12-Hydroxyoctadecanoate) is a non-ionic surfactant derived from sorbitol and 12-hydroxyoctadecanoic acid (12-hydroxystearic acid). This compound is valued for its excellent emulsifying, stabilizing, and solubilizing properties in complex formulations. It serves as a critical functional ingredient for manufacturers in the cosmetics, pharmaceuticals, and specialty chemical industries seeking reliable performance and ingredient compatibility.

Application

• Primary emulsifier and stabilizer in cosmetic creams, lotions, and ointments.
• Key component in pharmaceutical topical formulations for controlled drug release.
• Additive in industrial lubricants and metalworking fluids for improved surface activity.
• Processing aid and internal lubricant in polymer and plastic production.
• Emulsifier for specialty agrochemical formulations like pesticides and herbicides.
• Base material for synthesizing further sorbitan ester derivatives.
• Ingredient in personal care products such as sunscreens and makeup for texture enhancement.
