At present, the silicone oil products commonly used in cosmetics mainly include dimethyl silicone oil, methylphenyl silicone oil, cyclic silicone oil, hydroxy silicone oil, polyether silicone oil and long-chain alkyl modified silicone oil.


The outstanding properties of silicone oil used in cosmetics are mainly waterproof, lubricating, spreading, film-forming and compatibility. Silicone oil has low surface tension and good lubrication for the skin. Combined with suitable viscosity, it makes other components of cosmetics easy to disperse and form a delicate and uniform skin protective film on the skin to prevent dryness and wrinkles, and 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 prolong the effect of nutrient cream and medicated cream. The hydrophobicity of silicone oil prevents cosmetics with silicone oil from being easily lost due to washing or sweating.
