Description

Propane-1,2,3-Triyl Trilactate is a high-purity triester derived from lactic acid and glycerol, serving as a versatile, biodegradable intermediate and functional additive. Its structure offers excellent solvency and plasticizing properties, making it a valuable component in formulations requiring enhanced compatibility and performance. This compound is essential for manufacturers in the polymer, cosmetic, and specialty chemical industries seeking sustainable and effective raw materials.

Application

• As a biodegradable plasticizer for polymers like cellulose acetate and polyvinyl chloride (PVC) to improve flexibility and processability.
• As a solvent and carrier in cosmetic and personal care formulations, including creams, lotions, and makeup.
• As a chemical intermediate for the synthesis of more complex esters, surfactants, and lubricant additives.
• As a functional additive in coatings and inks to modify viscosity, drying time, and film properties.
• In the production of environmentally friendly lubricants and metalworking fluids.
• As a potential monomer or cross-linking agent in the development of bio-based polymers and resins.
