Description

Trihexadecyl Citrate is a high-molecular-weight ester derived from citric acid and cetyl alcohol. This compound serves as a versatile, non-toxic intermediate and additive, valued for its excellent lubricity, plasticizing properties, and chemical stability. It is particularly sought after by manufacturers in the cosmetics, plastics, and specialty lubricants industries seeking bio-based and skin-compatible ingredients.

Application

• Primary plasticizer and co-stabilizer in flexible PVC and other polymer formulations.
• Key emollient and skin-conditioning agent in high-end cosmetic and personal care products (e.g., creams, lotions).
• Functional additive in synthetic lubricants and metalworking fluids to enhance film strength and reduce friction.
• Intermediate for the synthesis of more complex esters and surfactants.
• Additive in adhesives and sealants to improve flexibility and processing.
• Component in food-contact polymer applications where non-toxicity is required.
• Used in textile auxiliaries as a softening and lubricating agent for fibers.
