overview
Silicone oil is a new type of green environmental protection material with many excellent properties, such as outstanding high and low temperature resistance, extremely low glass transition temperature, very low surface tension and surface energy, high hydrophobicity, and very low Solubility parameters and dielectric constants have been widely used in textile finishing agents, leather finishing agents, cosmetics, waterproof materials, coatings and photosensitive materials. Since silicone oil was applied in the 2070s, more than 30% cosmetics in Europe and the United States have added silicone oil with different specifications. However, due to its hydrophobicity, it increases the difficulty of its dispersion in the aqueous phase, which limits its application in some aspects. The emergence of emulsified silicone oil solves this problem. Driven by the wide application of emulsified silicone oil, the formulation research of silicone oil emulsifier is also constantly improving. The emulsifier formulation with convenient, low cost and better emulsion effect has a broader market prospect. Emulsified silicone oil is a milky white viscous liquid. No smell. Insoluble in water but dispersible in water. Insoluble in ethanol, methanol, soluble in aromatic hydrocarbons, aliphatic hydrocarbons and chlorinated hydrocarbons. It is made of polymethylsiloxane and fumed silica mixed and rolled into silicone grease, and then emulsified with polyvinyl alcohol, Tween 80 and deionized water.
