Description

1,2,3-Propanetricarboxylic Acid, 2-Hydroxy-, Tris(1-Methyl-C11-17-Alkyl) Esters is a high-purity synthetic ester derived from citric acid and branched C12-C18 alcohols. This compound matters for its excellent performance as a non-toxic, biodegradable plasticizer and lubricant additive, offering superior compatibility and stability in demanding formulations. It is primarily needed by manufacturers in the plastics, coatings, and specialty lubricants industries seeking sustainable and high-performance additive solutions.

Application

• Primary Plasticizer for PVC, PVA, and other polymers requiring low migration and high permanence.
• Lubricant and Grease Additive providing enhanced viscosity index and thermal stability.
• Co-additive in Metalworking Fluids for improved lubricity and corrosion protection.
• Stabilizer and Coalescing Agent in water-based paints and coatings.
• Plasticizer for Food-Contact Materials and medical-grade polymers (subject to specific grade compliance).
• Additive in Adhesives and Sealants to improve flexibility and low-temperature performance.
• Base Fluid for Synthetic Lubricants in high-performance industrial and automotive applications.
• Intermediate for the synthesis of more complex surfactant and ester molecules.
