Silicone oil is also called polysiloxane or silicone. It and its derivatives are high-quality raw materials for cosmetics, with physiological inertness and good chemical stability, odorless, non-toxic, non-irritating to the skin, and have good skin care functions.
 
It has lubricating properties, anti-ultraviolet radiation, good air permeability, slow release of flavors and fragrances, good anti-static, obvious dust-proof function, high stability, and does not affect the matching with other ingredients.
 
Silicone oil has high hydrophobicity, feels light and pleasant to use, and has good stretchability on hair and skin. The surface of raw materials is hydrophobic treated with silicone oil to improve the waterproof and sweatproof performance of cosmetics. Representative silicone oils include dimethyl silicone oil and methyl phenyl silicone oil.

A while ago, many people talked about the discoloration of silicone oil in cosmetics, thinking that silicone oil can cause skin allergies, and the skin cannot breathe, which is the main culprit of skin acne. In fact, the silicone oil contained in skin care products is not harmful as long as it is within the prescribed standards, but if it is excessive, it will indeed cause the pores to be blocked and the skin will be falsely slippery. Because silicone oil cannot be dissolved in water, if the pores are not deeply cleaned when cleaning the face, it will have a certain negative effect, but in essence, silicone oil will not harm the skin.
