Description

Stearoxy Dimethicone CAS NO 68554-53-0 is a specialized organomodified silicone polymer, engineered by grafting stearoxy groups onto a polydimethylsiloxane (PDMS) backbone. This unique structure provides exceptional emolliency, water repellency, and conditioning properties, making it a versatile functional additive. It is primarily sought after by formulators in the personal care and cosmetic industries to enhance product performance and sensory appeal.

Application

• Skin Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, and sunscreens, providing a smooth, non-greasy feel and improving spreadability.
• Hair Care Products: Used in shampoos, conditioners, and styling products to impart shine, reduce frizz, and enhance combability without buildup.
• Color Cosmetics: Serves as a pigment dispersant and binder in foundations, lipsticks, and mascaras, improving color payoff and long-wear properties.
• Antiperspirants & Deodorants: Functions as a lubricant and provides a dry, silky feel in stick and roll-on formulations.
• Industrial & Textile Coatings: Imparts water repellency and softness to textiles, leather, and paper coatings.
• Release Agents: Used in molding and manufacturing processes where a non-stick, lubricating surface is required.
