Description

Sorbitan, Di-9,12-Octadecadienoate, (All-Z)- is a non-ionic surfactant derived from sorbitol and linoleic acid, characterized by its (All-Z) configuration of the fatty acid chains. This compound is valued for its excellent emulsifying, dispersing, and solubilizing properties in both oil-in-water and water-in-oil systems. It serves as a critical functional ingredient for formulators in the personal care, cosmetics, pharmaceutical, and food industries, where consistent performance and ingredient compatibility are paramount.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary or co-emulsifier in creams, lotions, and makeup products for stable texture and smooth application.
• Pharmaceutical Excipient: Used in topical ointments, creams, and oral suspensions to improve drug solubility and emulsion stability.
• Food Industry Additive: Functions as an emulsifier in bakery products, margarines, and whipped toppings to ensure uniform texture and shelf-life.
• Industrial Applications: Serves as a dispersing agent in agrochemicals, lubricants, and textile processing aids.
• Paints & Coatings: Utilized to stabilize pigment dispersions and improve the consistency of water-based formulations.
