Description

Oleyl Isooctadecanoate is a high-purity, synthetic ester derived from oleyl alcohol and isooctadecanoic acid. This specialized chemical serves as a premium emollient and lubricant, prized for its excellent oxidative stability and skin-compatibility. It is a critical ingredient for formulators in the personal care, cosmetics, and high-performance lubricant industries seeking superior texture, spreadability, and long-term product integrity.

Application

• Personal Care & Cosmetics: Acts as a non-greasy, fast-absorbing emollient in creams, lotions, sunscreens, and makeup products to enhance skin feel and moisture retention.
• Hair Care Formulations: Used in conditioners, serums, and hair oils to impart shine, reduce frizz, and improve combability without heavy residue.
• Pharmaceutical Topicals: Serves as a base or carrier in ointments, gels, and transdermal delivery systems due to its skin-friendly and stable properties.
• Industrial & Metalworking Fluids: Functions as a synthetic lubricant and corrosion inhibitor in specialty oils and greases requiring high thermal stability.
• Plastic & Polymer Additive: Employed as an internal or external lubricant and plasticizer in polymer processing to improve flow and surface finish.
• Textile & Fiber Treatment: Applied as a softening and anti-static agent on synthetic and natural fibers to enhance handle and processing.
