Description

Sorbitan, Didocosanoate is a high-purity, non-ionic surfactant derived from sorbitol and behenic acid. This specialized ester is valued for its excellent emulsifying, stabilizing, and conditioning properties in demanding formulations. It serves as a critical functional ingredient for manufacturers in the personal care, cosmetics, and specialty chemical industries seeking reliable performance and ingredient integrity.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and stabilizer in high-end creams, lotions, and sunscreens, providing a smooth texture and enhanced skin feel.
• Hair Care Formulations: Used as a conditioning agent and emollient in shampoos, conditioners, and hair styling products to improve manageability and reduce static.
• Pharmaceutical Auxiliary: Serves as a non-ionic surfactant in topical ointments, creams, and controlled-release drug delivery systems.
• Industrial Lubricants & Additives: Functions as an emulsifier and anti-static agent in synthetic lubricants, metalworking fluids, and textile processing aids.
• Food-Grade Applications (where specified): Can be utilized as an emulsifier in certain food additive blends, subject to specific purity grade and regulatory compliance.
• Paints & Coatings: Employed as a dispersing agent and flow improver in water-based and solvent-based coating systems.
