Description

Isocetyl Stearate is a high-purity, branched-chain fatty acid ester derived from stearic acid and isocetyl alcohol. This compound serves as an exceptional emollient and lubricant, valued for its non-greasy feel, excellent skin compatibility, and stability in formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking superior texture and performance in their products.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup products, providing a smooth, silky after-feel.
• Pharmaceutical Topicals: Used as a non-irritating base and penetration enhancer in ointments, dermatological creams, and transdermal delivery systems.
• Hair Care Products: Functions as a conditioning agent and gloss enhancer in shampoos, conditioners, and hair styling products, reducing frizz and improving manageability.
• Industrial Lubricants & Release Agents: Serves as a biodegradable lubricant and mold release agent in plastic, rubber, and metalworking processes.
• Textile & Fiber Processing: Employed as a softening agent and spin finish for synthetic fibers and textiles to improve hand feel and processing.
