Silicone oil is generally a colorless (or light yellow), odorless, non-toxic, non-volatile liquid. Silicone oil is insoluble in water, methanol, ethylene glycol and 2-ethoxyethanol, miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene, and slightly soluble in acetone, dioxane, ethanol and Butanol. It has a small vapor pressure, high flash point and fire point, and low freezing point. As the number of chain segments n increases, the molecular weight increases and the viscosity also increases. Therefore, silicone oil can have various viscosities, from 0.65 centistokes to millions of centistokes. If you want to prepare low-viscosity silicone oil, you can use acidic clay as a catalyst and telomerize at 180°C, or use sulfuric acid as a catalyst and telomerize at low temperature to produce high-viscosity silicone oil or viscous materials. catalyst.

Water-in-oil (W/O) silicone emulsifiers play a crucial role in the formulation of cosmetics by creating stable emulsions where water droplets are dispersed in an oil phase. This unique structure allows for the delivery of water-soluble ingredients into oil-based products, enhancing their moisturizing and nourishing effects. W/O emulsifiers also contribute to the texture and sensory experience of cosmetics, providing a rich, creamy feel that is often preferred by consumers for its luxurious and hydrating sensation. Additionally, they improve the stability and shelf life of products by preventing phase separation, ensuring consistent performance over time.
