Description

14-Methylpentadecyl Octadecanoate is a high-purity synthetic ester, specifically the branched-chain isohexadecyl ester of stearic acid. This compound is valued for its excellent emollient properties, oxidative stability, and compatibility with a wide range of cosmetic and industrial formulations. It is primarily sought by manufacturers in the personal care, lubricant, and specialty chemical industries seeking a non-greasy, skin-friendly ester with superior thermal and hydrolytic stability.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, sunscreens, and lipsticks, providing a smooth, non-oily feel.
• Lubricant & Metalworking Fluids: Serves as a synthetic base oil or additive, offering good lubricity, high viscosity index, and low volatility for demanding industrial applications.
• Plasticizer & Polymer Additive: Used to improve the flexibility and processability of various polymers and resins without compromising stability.
• Textile & Fiber Processing: Functions as a softening agent and lubricant for synthetic fibers and yarns during manufacturing.
• Release Agent & Mold Lubricant: Applied in rubber, plastic, and composite molding processes to ensure clean part release from molds.
• Specialty Greases & Waxes: Incorporated into formulations to modify consistency, melting point, and water repellency.
