Description

Hexyl Methicone CAS NO 1873-90-1 is a specialized organosilicon compound, specifically a linear alkyl-modified silicone fluid. This product is valued for its unique combination of silicone-derived properties with the hydrophobic and emollient characteristics of a hexyl chain. It serves as a high-performance ingredient, offering exceptional spreading, lubricity, and water repellency without a greasy feel. Key industries that utilize this advanced material include personal care, cosmetics, and industrial lubricant formulations.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and spreading agent in sunscreens, lotions, creams, and color cosmetics for a dry, silky skin feel.
• Hair Care Products: Used in conditioners, serums, and styling products to provide shine, reduce frizz, and improve combability without buildup.
• Skin Care Formulations: Enhances the texture and sensory profile of anti-aging serums, moisturizers, and makeup primers.
• Industrial Lubricants & Release Agents: Functions as a non-greasy lubricant and mold release agent in plastics, rubber, and metalworking applications.
• Water-Repellent Coatings: Imparts durable water repellency to textiles, leather, and paper products.
• Plastic and Rubber Additives: Improves surface slip, processability, and acts as an internal lubricant.
