Two commonly used silicone oils in shampoo formulations

When consumers choose a shampoo formula, the most needed function is to clean their hair. The surfactants in shampoo are mainly used to remove grease and dust from the scalp and hair. Current shampoos can make people's hair shiny and smooth after washing, which is the function of silicone oil. Silicone oil is a very good smoothing agent that can greatly reduce friction resistance, and it can make the hair smooth, including in some current cosmetics, Silicone oil mixed with various silicon containing compounds will be used.

Therefore, the role and status of silicone oil in shampoo is self-evident. In the formulation of shampoo, organic silicone oil and emulsified silicone oil are commonly used types of shampoo formulations. Because organic silicone oil and emulsified silicone oil are excellent materials as lubricants, shampoos that add organic silicone oil or emulsified silicone oil can make your hair particularly bright and smooth after washing. Therefore, the quality and quality of organic silicone oil and emulsified silicone oil will fundamentally affect the quality of shampoo. The emulsified silicone oil produced by Qingdao Xingye Organosilicon New Material Co., Ltd. is not a product purchased by other emulsified silicone oil manufacturers. It has been independently developed for many years, and its quality and reputation are trustworthy. The following is a brief introduction to the properties and characteristics of organic silicone oil and emulsified silicone oil. Shampoo antifreeze

(1) Emulsified silicone oil: Emulsified silicone oil has stable chemical properties, is nonvolatile, is not easy to burn, is non corrosive to metals, and is not easy to gelatinize when exposed to air for a long time. Its property is a white viscous liquid with a viscosity of about (100~350) × 10-6m2/s, relative density 0.98-1.02, almost odorless, insoluble in water (dispersible in water), ethanol, methanol, and soluble in aromatic, aliphatic, and chlorinated hydrocarbons (such as benzene, carbon tetrachloride, etc.).

(2) Organosilicone oil: Organosilicone oil is a kind of polyorganosiloxane with different polymerization degree chain structure. It is prepared by hydrolysis of dimethyldichlorosilane with water to obtain an initial polycondensation ring. The ring is cracked and rectified to obtain a low ring. Then, the ring, sealing agent, and catalyst are placed together to obtain a mixture of various degrees of polymerization. After vacuum distillation, the low boiling matter is removed to produce organosilicon oil. Its properties are colorless (or light yellow), odorless, non-toxic, and nonvolatile liquid. "Organic silicone oil is insoluble in water, methanol, diol, and - ethoxyethanol, and is miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride, or kerosene. It is slightly soluble in acetone, dioxane, ethanol, and alcohol.". It has a low vapor pressure, a high flash and ignition point, and a low freezing point. As the number of chain segments n varies, the molecular weight increases, and the viscosity also increases. This silicone oil can have various viscosities, from 0.65 centistokes to millions of centistokes. If low viscosity silicone oil is to be prepared, acidic clay can be used as a catalyst and polymerized at 180 ℃, or sulfuric acid can be used as a catalyst and polymerized at low temperature. Alkaline catalysts can be used to produce high viscosity silicone oil or viscous substances.
