Description

Isostearyl Acetate is a high-purity, synthetic ester derived from isostearyl alcohol and acetic acid, valued for its exceptional emolliency, low viscosity, and excellent skin feel. This versatile chemical serves as a non-greasy, fast-spreading emollient and solvent, offering superior stability and compatibility in demanding formulations. It is primarily sought after by manufacturers in the personal care, cosmetics, and pharmaceutical industries for creating premium skin creams, lotions, sunscreens, and color cosmetics.

Application

• Personal Care & Cosmetics: A key emollient in facial creams, body lotions, and anti-aging serums for its silky, non-oily skin feel.
• Sunscreen & SPF Formulations: Acts as a solvent and spreading agent for organic UV filters, enhancing product aesthetics and application.
• Color Cosmetics: Used in lipsticks, foundations, and mascaras to improve pigment dispersion, texture, and wear comfort.
• Hair Care Products: Incorporated into conditioners and hair serums as a lubricant and glossing agent that reduces frizz without heaviness.
• Pharmaceutical Topicals: Serves as a carrier or emollient base in ointments, creams, and medicated lotions.
• Industrial Lubricants & Release Agents: Functions as a synthetic lubricant base or mold release agent in specialized manufacturing processes.
