Description

Sorbitan, Dihexadecanoate is a non-ionic surfactant and emulsifier derived from sorbitol and palmitic acid. This compound is valued for its ability to stabilize emulsions and modify surface tension in complex formulations. It serves as a critical functional ingredient for manufacturers in the personal care, food, and pharmaceutical industries seeking reliable and consistent performance.

Application

• Primary emulsifier and co-emulsifier in cosmetic and personal care creams, lotions, and ointments.
• Food-grade emulsifier and stabilizer in baked goods, confectionery, and whipped toppings.
• Key component in industrial lubricants and textile processing aids.
• Used in pharmaceutical formulations as a non-toxic surfactant for topical preparations.
• Acts as a dispersing agent in agricultural chemicals and pesticide formulations.
• Intermediate in the synthesis of more complex polysorbate surfactants.

Quality Control

Our Sorbitan, Dihexadecanoate is produced under a strict quality management system. Each batch is tested to ensure it meets specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and saponification value are available upon request. We can support compliance with relevant standards including FCC for food-grade 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 hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent caking or hydrolysis. For long-term storage, consider using an inert atmosphere to minimize oxidation.
