Silicone oil usually refers to organopolysiloxane that is liquid at room temperature, has good film-forming agent, hydrophobicity, air permeability, stable chemical properties, non-toxic, the scientific name in shampoo is "polydimethylsiloxane". alkyl". The viscosity and spreadability of silicone oil has a moisturizing and smoothing effect on the hair. When washing your hair, the silicone oil in the shampoo can be absorbed in the gaps of the cuticles, making the hair feel soft and reducing the friction between the hairs. At the same time, silicone oil can also form a protective layer to keep the moisture content of the hair stable and reduce damage to the hair cuticles.

Many people worry that silicone oil will clog pores, but in fact, the concentration of silicone oil in shampoo products is generally around 1%-4%. Some of the silicone oil added in shampoo is soluble in water and will be washed away by water when shampooing. The amount of silicone oil that is insoluble in water is simply a drop in the bucket compared to the amount of oil secreted by the human scalp in one day.

The choice of shampoo should be based on your hair condition and needs. If you often dye your hair perm or have hair care needs, you can choose a shampoo containing silicone oil; if you have strong oil secretion, etc., choose a silicone-free shampoo, which can give your hair for a fluffy effect.

In addition, there are also silicone oils in cosmetics. From the perspective of molecular structure, the molecular chain of silicone oil contains a variety of different chemical bonds, which endow the silicone oil with different properties. Because of this, silicone oil is widely used in daily chemicals, especially cosmetics. Among them, methyl silicone oil can form a hydrophobic and breathable protective film on the skin surface, and is often used in lubricants and skin care agents. Methyl phenyl silicone oil has stronger cold resistance and improves compatibility with other base materials, and is often used as a film-forming agent for facial masks and a radiation-resistant agent for sunscreens. Other synthetic silicone oils are also used in lipsticks to improve the moisture and breathability of lipsticks; used in shampoos to improve the properties of foam; added in toothpastes to prevent yellow teeth caused by smoking and prevent the occurrence of dental caries.... .
