Description

Sorbitan, Bis(12-Hydroxy-9-Octadecenoate), [R-[R*,R*-(Z,Z)]]- is a specialized sorbitan ester derivative of ricinoleic acid, a naturally occurring hydroxy fatty acid. This compound serves as a versatile non-ionic surfactant and emulsifier, prized for its ability to stabilize complex mixtures and modify surface properties. It is a critical ingredient for formulators in the cosmetics, personal care, pharmaceutical, and specialty chemical industries seeking high-performance, bio-based functional additives.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary or co-emulsifier in creams, lotions, and makeup, providing stable emulsions and a smooth skin feel.
• Pharmaceutical Delivery Systems: Used in the preparation of emulsions, ointments, and as a solubilizing agent for active pharmaceutical ingredients (APIs).
• Industrial Lubricants & Additives: Functions as an emulsifier, corrosion inhibitor, and friction modifier in metalworking fluids and synthetic lubricants.
• Polymer & Resin Additive: Serves as an internal or external lubricant and release agent in plastic and polymer processing.
• Agricultural Adjuvants: Enhances the efficacy of pesticides and herbicides by improving spreading, wetting, and penetration on plant surfaces.
• Food-Grade Emulsifier (subject to grade/purity): Potential use in food applications as an emulsifier (e.g., E494) for bakery products, confectionery, and edible spreads.
• Textile & Leather Processing: Employed as a softening agent, lubricant, and finishing agent in textile and leather treatment processes.
