Description

Sorbitan, Mono-10-Undecenoate is a non-ionic surfactant derived from sorbitol and undecylenic acid, characterized by its unique unsaturated fatty acid chain. This compound matters as a versatile emulsifier and stabilizer, offering enhanced reactivity and functionality in formulations requiring cross-linking or polymerization due to its terminal double bond. Industries such as polymer synthesis, specialty coatings, and advanced personal care need it for creating tailored, high-performance products where chemical modification is key.

Application

• Polymer & Resin Industry: Acts as a reactive surfactant and emulsifier in the production of specialty polymers, including alkyd resins and polyesters, where its unsaturated bond allows for copolymerization.
• Advanced Coatings & Inks: Serves as a dispersing agent and stabilizer in UV-curable coatings, inks, and adhesives, improving film formation and final product properties.
• Personal Care & Cosmetics: Used as an emulsifier in high-end cosmetic formulations, such as creams and lotions, providing stable emulsions with a smooth texture.
• Lubricant & Metalworking Fluids: Functions as an additive and emulsifier in synthetic lubricants and cutting fluids, enhancing lubrication and stability.
• Pharmaceutical Excipients: Employed as a non-ionic surfactant in topical drug delivery systems and emulsion-based pharmaceutical preparations.
• Agricultural Formulations: Utilized as an adjuvant and emulsifier in pesticide and herbicide concentrates to improve sprayability and active ingredient dispersion.

Quality Control

Our Sorbitan, Mono-10-Undecenoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting purity, acid value, hydroxyl value, and iodine value are available upon request to support your quality assurance protocols.

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). Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain product integrity. Keep away from strong oxidizing agents.
