Is dimethyl silicone oil harmful when used in cosmetics?
Many cosmetics on the market contain silicone oil products. Just like the use of alcohol in cosmetics, many people think that using cosmetics containing alcohol is bad for the skin. In fact, alcohol can help dissolve many ingredients that are difficult to dissolve. However, it is not suitable for people with sensitive skin. When people hear that cosmetics contain silicone oil, they will also be very resistant to such cosmetics. Are cosmetics containing silicone oil really harmful?
In addition to being used directly, polydimethylsiloxane can also be formulated into three types, namely solution type, lipid type and emulsion type, for use in order to make methyl silicone oil disperse well, facilitate impregnation and spraying, and improve efficiency. It and its derivatives are high-quality raw materials for cosmetics, have good skin care functions, and belong to synthetic oils among cosmetic raw materials. This product is non-toxic, non-irritating to the skin and mucous membranes, but irritating to the eyes. Generally, it is recognized as safe.
The moisturizing property of polydimethylsiloxane: Polysiloxane is the general term for this kind of substances, also known as silicone or silicone oil, all belonging to this category. In cosmetics, it has lubricating properties, anti-ultraviolet effects, good air permeability, and obvious dust-proof functions. It is also used in cosmetics to replace traditional oil raw materials. This is based on the characteristic that polydimethylsiloxane has good softness. It is usually used in moisturizing products in skin care products, and is also used in some high-end skin care products.
The permeability of polydimethylsiloxane: Polydimethylsiloxane has very good permeability to the skin. The smooth and refreshing feeling when skin care products are applied to the skin is usually due to the addition of this raw material. The raw material itself also has a good effect on increasing the softness of the skin. In hair care and shampoo products, it can deepen the color of hair and help hair maintain its natural luster. Basically, this raw material can be found in shampoos that can make hair smooth.
In cosmetics, polydimethylsiloxane is required to have low viscosity, good volatility and be easy to clean. The maximum usage proportion can reach more than 15%. The conclusion of the Cosmetic Ingredient Review Expert Panel is that dimethylsiloxane and related derivatives are "formulated in safe cosmetics". Dimethyl silicone oil can be used in cosmetics, but special attention should be paid to this proportion.
