Description

Docosyl Dihydrogen Citrate is a high-purity, long-chain fatty acid derivative of citric acid. This specialized chemical is valued for its unique combination of a hydrophilic citrate head and a long hydrophobic docosyl (C22) tail, making it an effective emulsifier, dispersant, and intermediate. It is essential for formulators and manufacturers in the personal care, cosmetics, and specialty chemical industries seeking to create stable, high-performance products. Its structure also lends itself to applications in polymer modification and as a surface-active agent.

Application

• Cosmetic & Personal Care Formulations: Acts as a non-ionic emulsifier and skin-conditioning agent in creams, lotions, and ointments.
• Pharmaceutical Excipient: Used as a solubilizer, emulsifier, or controlled-release matrix component in topical drug delivery systems.
• Polymer Additive: Serves as a plasticizer, lubricant, or compatibilizer in specialty polymer and resin production.
• Industrial Dispersant: Effective for stabilizing pigments, fillers, and nanoparticles in various coating and composite systems.
• Food-Grade Emulsifier (Potential): With appropriate purification, can be explored for use in food-grade emulsification applications.
• Lubricant & Grease Additive: Imparts anti-wear and friction-modifying properties in synthetic lubricant formulations.
• Chemical Intermediate: Used in the synthesis of more complex esters, surfactants, and specialty organic compounds.
