Description

Sorbitan, Monoisohexadecanoate CAS NO 97635-38-6 is a non-ionic surfactant derived from sorbitol and isohexadecanoic acid, functioning as a versatile emulsifier and solubilizer. Its primary value lies in its ability to stabilize oil-in-water emulsions and enhance the compatibility of hydrophobic components in complex formulations. This makes it an essential ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking to improve product texture, stability, and performance.

Application

• Primary emulsifier and stabilizer in cosmetic creams, lotions, and sunscreens.
• Key ingredient in pharmaceutical ointments and topical delivery systems for active ingredients.
• Used as a dispersing agent and co-emulsifier in industrial and agrochemical formulations.
• Functions as a solubilizer for fragrances and essential oils in personal care products.
• Employed in the production of food-grade emulsifiers and food additive blends (where specific grade compliance is met).
• Additive in lubricants and metalworking fluids for its surface-active properties.
