Description

Octyl Isooctadecanoate is a high-purity, synthetic ester widely recognized for its exceptional emolliency and skin-feel properties. This versatile compound serves as a premium, non-greasy emollient and solvent, offering excellent stability and compatibility in demanding formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and specialty lubricants industries seeking to enhance product performance and sensory appeal.

Application

• Personal Care & Cosmetics: A key emollient in high-end skin creams, lotions, sunscreens, and makeup products for its smooth, dry skin feel and excellent spreadability.
• Hair Care Formulations: Used in conditioners, serums, and styling products to impart shine, reduce frizz, and improve combability without heaviness.
• Color Cosmetics: Acts as a pigment wetting agent and binder in lipsticks, foundations, and eye shadows, enhancing color payoff and wear.
• Pharmaceutical Topicals: Employed as a base or carrier in ointments and medicated creams for its inert nature and skin penetration characteristics.
• Specialty Lubricants: Functions as a synthetic base oil or additive in specialty lubricants requiring high thermal stability and low volatility.
• Plasticizer & Processing Aid: Used as a secondary plasticizer or processing aid in select polymer applications to improve flexibility and mold release.
