Description

Pentaerythrityl Tetramyristate is a high-purity, synthetic ester derived from pentaerythritol and myristic acid, serving as a versatile and stable emollient and lubricant. Its value lies in its excellent oxidative stability, low volatility, and compatibility with a wide range of cosmetic and industrial formulations. This product is essential for manufacturers in the personal care, pharmaceutical, and specialty lubricant industries seeking high-performance, non-greasy conditioning agents and base fluids.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, lipsticks, and sun care products, providing a smooth, non-greasy feel.
• Pharmaceutical Topicals: Used as an excipient in ointments, creams, and topical drug delivery systems for its stability and skin compatibility.
• Specialty Lubricants & Greases: Functions as a high-performance synthetic base oil or additive in food-grade, textile, and precision instrument lubricants due to its thermal stability.
• Plasticizer & Polymer Additive: Imparts flexibility and lubrication as a secondary plasticizer or processing aid in PVC and other polymer systems.
• Release Agent & Mold Lubricant: Employed in industrial molding and casting processes to facilitate clean part release.
• Metalworking Fluids: Serves as a lubricity component in synthetic and semi-synthetic cutting and grinding fluids.
