Dimethyl silicone oil

　　Core Application Areas

　　1. Cosmetics and Personal Care

　　Skin Feel Modifiers: Low viscosity silicone oils (e.g., 10-100 cSt) are added to face creams, lotions, shampoos, and other products to form breathable films, reduce stickiness, and impart a smooth touch to skin/hair (e.g., the smoothing ingredients in "silicone shampoos").

　　Moisturizing and Protection: High viscosity silicone oils (e.g., 1000-10000 cSt) are used in lipsticks and sunscreens to block moisture evaporation while resisting external contaminants (chemical inertness).

　　Makeup Base: Used as a dispersant for foundations and eyeshadows to improve spreadability and sweat resistance (hydrophobic properties).

　　2. Pharmaceuticals and Medical

　　Antifoaming Agents: Administered orally or used in endoscopy (e.g., gastroscopy, colonoscopy); utilizes low surface tension to rupture bubble films, eliminating foam in the gastrointestinal tract to clearly display lesions (pharmacopeia-grade silicone oil complies with USP/NF standards).

　　Medical Excipients: Used as a base for ointments and creams (e.g., burn ointments), providing lubrication, isolation (preventing wound adhesion), and sustained drug release.

　　Medical Devices: Used as a lubricant for catheters and syringes to reduce mucosal damage; used as a coating for intraocular lenses and contact lenses to improve biocompatibility.

　　3. Mechanical and Industrial

　　High-Temperature Lubricants: Used for bearing lubrication in automobiles and motors (stable operation from -40℃ to 200℃), especially suitable for high-temperature equipment (e.g., ovens, boilers).

　　Release Agents: Used as release agents during the molding of rubber, plastic, and concrete products; due to non-stick properties, they are reusable and do not contaminate the product surface.

　　Sealants: Mixed with curing agents to form silicone rubber, used for waterproof sealing of electronic components and pipes (aging resistant, adapts to alternating cold and heat).

　　4. Textiles and Leather

　　Softening Finishes: Soaking or spraying fabrics (cotton, synthetic fibers) to form a film, reducing fiber friction, making fabrics smoother and wrinkle-resistant (e.g., "non-iron" shirt treatment).

　　Leather Finishing: Improves the gloss and abrasion resistance of leather while maintaining breathability (silicone oil molecular gaps allow gas permeability).

　　5. Food Industry

　　Food-Grade Antifoaming Agents: Eliminate foam in sugar production, brewing, and soy product processing (complies with GB 2760 standard, addition amount ≤0.05%), without affecting food flavor (odorless, non-toxic);

　　Food Mold Release: Used for chocolate and candy molds to prevent sticking and facilitate easy cleaning.
