Description

Isohexadecyl Isooctadecanoate is a high-purity, branched-chain ester known for its exceptional stability and emollient properties. This specialty chemical serves as a premium, non-greasy lubricant and skin-conditioning agent, offering superior oxidative and thermal resistance compared to linear esters. It is a critical ingredient for formulators in the personal care, cosmetics, and high-performance lubricant industries seeking to enhance product texture, spreadability, and longevity. Its unique structure provides excellent compatibility with a wide range of oils and waxes.

Application

• Personal Care & Cosmetics: Acts as a high-performance emollient and skin-conditioning agent in creams, lotions, sunscreens, and color cosmetics for a smooth, non-greasy feel.
• Lubricants & Greases: Serves as a synthetic base oil or additive in specialty lubricants, metalworking fluids, and greases requiring high thermal and oxidative stability.
• Plasticizers & Polymers: Used as a secondary plasticizer and processing aid to improve flexibility and workability in polymer formulations.
• Textile & Fiber Treatment: Functions as a softening agent and lubricant for synthetic fibers and yarns during processing.
• Industrial Coatings & Inks: Employed as a leveling and flow agent to improve the application properties and final finish of coatings and printing inks.
• Adhesives & Sealants: Enhances the plasticity and low-temperature performance of adhesive and sealant formulations.
