Description

1,2,3-Propanetriyl Tris[12-(Acetoxy)Octadecanoate] is a high-purity synthetic ester, specifically a triglyceride derivative of 12-acetoxystearic acid. This compound is valued for its role as a versatile intermediate and functional additive, offering unique properties derived from its long-chain, acetylated fatty acid structure. It is primarily sought by manufacturers in the cosmetics, personal care, and specialty chemical industries for formulating advanced emollients, viscosity modifiers, and release agents.

Application

• Cosmetic & Personal Care Formulations: Acts as a high-performance emollient and skin-conditioning agent in creams, lotions, and makeup products.
• Plasticizer & Lubricant Intermediate: Used in the synthesis of specialized plasticizers and lubricants for polymers and industrial applications.
• Release Agent Production: Serves as a key component in formulating mold release agents for the plastics and rubber industries.
• Pharmaceutical Excipient: Employed as a lipid-based carrier or solubilizing agent in topical and transdermal drug delivery systems.
• Specialty Greases & Waxes: Functions as a modifying agent to alter the melting point, texture, and consistency of synthetic greases and waxes.
• Chemical Synthesis: Utilized as a building block or derivatization agent in organic synthesis and research chemistry.
