Description

2-Hydroxy-1,2,3-Propanetricarboxylic Acid Dihydrogen 1-[2-Hydroxy-3-(Octadecyloxy)Propyl] Ester is a specialized ester derivative of citric acid, designed to combine the chelating and buffering properties of the parent acid with the hydrophobic character of a long-chain alkyl group. This unique amphiphilic structure makes it a valuable functional additive for modifying surface properties and enhancing compatibility in complex formulations. It is primarily sought by manufacturers in the polymer, personal care, and specialty chemical industries for its role as a stabilizer, emulsifier, or compatibilizer.

Application

• Polymer Additive: Acts as a processing aid, internal lubricant, or anti-static agent in plastics and synthetic resins.
• Personal Care Formulations: Used as an emulsifier or stabilizer in creams, lotions, and other cosmetic products requiring oil-in-water systems.
• Industrial Lubricants & Greases: Functions as a corrosion inhibitor and thickening agent in specialty lubricant formulations.
• Coatings & Inks: Serves as a dispersing agent or flow modifier to improve pigment wetting and film formation.
• Metal Working Fluids: Utilized as a component in synthetic coolants and drawing compounds for its emulsifying and chelating properties.
• Adhesives & Sealants: Enhances adhesion and modifies rheology in various adhesive systems.
