Description

Sorbitan, Tridocosanoate is a high-purity, non-ionic surfactant and emulsifier derived from sorbitol and behenic acid. This specialized ester is valued for its excellent 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 batch-to-batch consistency.

Application

• Primary emulsifier and stabilizer in high-viscosity creams, lotions, and ointments for personal care.
• Key conditioning agent in hair care products such as conditioners and styling aids to impart softness and manageability.
• W/O (water-in-oil) emulsion stabilizer in cosmetic foundations, sunscreens, and cold creams.
• Lubricant and processing aid in the production of plastics and synthetic fibers.
• Additive and dispersant in specialty coatings, inks, and industrial fluid formulations.
• Base material for the synthesis of further specialty surfactants and esters.

Quality Control

Our Sorbitan, Tridocosanoate is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting key parameters such as assay, acid value, saponification value, and hydroxyl value is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality.
