Description

Stearyl Aminopropyl Methicone is a high-performance organomodified silicone, specifically a long-chain alkyl amino-functional siloxane. This unique structure provides exceptional conditioning, softening, and substantivity to various substrates, making it a critical ingredient for formulators seeking superior performance. It is particularly valuable in the personal care and cosmetic industries for its ability to deliver luxurious feel and durable benefits. The compound is identified by CAS No. 110720-64-4.

Application

• Hair Care Formulations: As a premium conditioning agent in shampoos, conditioners, and hair masks to impart exceptional softness, manageability, and shine with reduced static.
• Skin Care & Color Cosmetics: Used in creams, lotions, and makeup products to enhance skin feel, provide a smooth, silky afterfeel, and improve pigment dispersion and wear.
• Antiperspirants & Deodorants: Functions as a lubricant and feel modifier, improving the application smoothness and skin compatibility of stick and roll-on formulations.
• Textile & Fiber Treatment: Imparts durable softness, lubricity, and anti-static properties to natural and synthetic fibers during finishing processes.
• Industrial Polishes & Coatings: Acts as a leveling and slip agent, enhancing gloss, scratch resistance, and surface smoothness in various protective coatings.
