Description

Sorbitan, Tri-9,12-Octadecadienoate, (All-Z)- CAS NO 93894-51-0 is a non-ionic surfactant derived from sorbitol and linoleic acid, characterized by its (All-Z) stereochemistry. This compound is valued for its excellent emulsifying, dispersing, and solubilizing properties in non-aqueous systems. It serves as a critical functional ingredient for formulators in the cosmetics, personal care, and specialty chemical industries seeking stable, high-performance oil-phase components.

Application

• Primary emulsifier and co-emulsifier in cosmetic creams, lotions, and ointments.
• Dispersing agent for pigments and actives in makeup and sun care products.
• Key component in W/O (water-in-oil) emulsion systems for long-lasting skin feel.
• Solubilizer for lipophilic compounds in personal care and topical pharmaceutical preparations.
• Used as a lubricant and processing aid in polymer and resin formulations.
• Intermediate for the synthesis of more complex surfactants and specialty esters.

Quality Control

Our Sorbitan Trilinoleate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, acid value, hydroxyl value, and other critical parameters is provided with every shipment to guarantee consistency and compliance for your applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve stability and prevent rancidity. Keep away from strong oxidizers and heat sources.
