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.

Cosmetic Polyvinyl Pyrrolidone PVP K90 is a versatile polymer widely used in the cosmetic industry. It is a synthetic ingredient made by polymerizing N-vinylpyrrolidone monomer, and its excellent properties make it a useful ingredient in a variety of cosmetic products.

As a design to replace D5, SQ-SIL V5 boasts a similar function and structure to cyclopentasiloxane (D5), yet without the application limits. This dimethicone variant, with its moderate volatility, ensures it stays on the skin or hair surface, providing a lubricious and clear appearance that enhances your natural glow.

Brief introduction of common emulsifiers used in cosmetics. Comparing different types with their strength. In the meantime, briefly sharing ShengQing key products including Cetyl PEG/PPG-10/1 Dimethicone（SQ-SE 1090）and Lauryl PEG/PPG-18/18 Dimethicone（SQ-SE 1200）.

Which combination is better in shampoo: Cyclopentasiloxane and Dimethicone, or Dimethicone and Dimethiconol? The roles of the two silicone combinations in shampoo are very distinct, and can be summarized in one sentence: . Cyclopentasiloxane & Dimethicone = "Quick smoothness, then stability" Dimethicone & Dimethiconol = "Long-lasting repair"
