Description

Pentaerythrityl Tetracaprylate/Caprate is a synthetic ester derived from pentaerythritol and a blend of caprylic and capric fatty acids. This compound serves as a high-performance, non-greasy emollient and solvent with excellent oxidative stability and low volatility. It is primarily needed by formulators in the personal care, cosmetics, and lubricant industries seeking versatile, skin-compatible base fluids and carriers.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and solvent in sunscreens, creams, lotions, and makeup, providing a dry, silky skin feel.
• Lubricants & Functional Fluids: Used as a base stock or additive in synthetic lubricants, metalworking fluids, and compressor oils due to its thermal stability.
• Plasticizer: Imparts flexibility and low-temperature properties to polymers and elastomers in specialty applications.
• Carrier Oil: Serves as an effective, odorless, and colorless vehicle for fragrances, vitamins, and active ingredients.
• Industrial Coatings & Inks: Functions as a low-VOC coalescing agent or plasticizer to enhance film formation and flexibility.
