Currently, silicone oil products commonly used in cosmetics mainly include dimethyl silicone oil, methylphenyl silicone oil, cyclic silicone oil, hydroxyl silicone oil, polyether silicone oil and long-chain alkyl modified silicone oil. The outstanding properties of silicone oil used in cosmetics include waterproofing, lubricity, spreading, film-forming and compatibility. Silicone oil has low surface tension and has a good lubricating effect on the skin. Combined with the appropriate viscosity, the other components of the cosmetics can be easily dispersed and form a delicate and even skin protective film on the skin to prevent dryness and wrinkles. , it can also ensure the normal breathing of the skin and treat dermatitis and eczema. The protective film can also prolong the effect of active ingredients in cosmetics, effectively extending the effect of nutritional creams and medicinal creams. The hydrophobicity of silicone oil prevents cosmetics containing silicone oil from being easily lost due to washing or sweating. Silicone oil has good compatibility with most cosmetic additives. Good compatibility and compatibility provide greater choices for cosmetic formulas and facilitate the development of different types of high-end cosmetics. The detackiness of silicone oil allows it to be combined with petroleum jelly, paraffin, beeswax, lanolin, etc. to obtain non-sticky products.
Volatile silicone oil can give cosmetics quick-drying, smooth and anti-fouling properties; methylphenyl silicone oil has a certain effect of absorbing ultraviolet rays, and phenyl group can enhance the compatibility of silicone oil with other oil compounds; long-chain alkyl modified silicone oil It has good gloss, increases the brightness and luster of cosmetics, and has better compatibility with carbon-based compounds; hydroxyl silicone oil can improve the compatibility and compatibility with other raw materials of cosmetics; polyether silicone oil is suitable for water-based applications Cosmetics have good compatibility with hydrophilic compounds and have a certain emulsifying effect. They can be used as emulsifiers for cream products or lotions.
