Some time ago, some consumers talked about silicon discoloration, which mainly involved traditional silicone oil shampoos. Probably because of the overwhelming advertisements, many people already believe that the silicone oil in shampoo is harmful. In fact, silicone oil has been serving in the hair care field for nearly 50 years without complaint, but it has suddenly stood on the cusp of the storm in recent years, and it has become a bit of a shame.
     In fact, silicone oil generally refers to linear polysiloxane products that remain liquid at room temperature. It is generally divided into two types: methyl silicone oil and modified silicone oil. The most commonly used silicone oil - methyl silicone oil, also known as ordinary silicone oil, its organic groups are all methyl, methyl silicone oil has good chemical stability, insulation, and good hydrophobicity. The popular explanation is: siloxane Si-O-Si bond constitutes a polymer with a main chain structure. It is customarily called silicone or polysiloxane, which can be a linear, cyclic or cross-linked polymer.
     Silicon-containing raw materials have no conclusive laws and regulations that are harmful to the human body. As long as the raw materials used can be found in the "Catalogue of Names of Cosmetic Raw Materials Used (2015 Edition)", they are all legal and compliant. Of course, the premise of legal compliance is that the amount added is within a certain range. For example, everyone knows that skin care products added with glycerin have a moisturizing effect, but if the content of glycerin is added to a large amount, glycerin will absorb water from the skin instead, which has a counterproductive effect. Therefore, as a consumer, there is no need to panic when choosing skin care products containing silicon raw materials. As long as the selected skin care products have been registered in the domestic non-special or special-purpose cosmetics of the "Food and Drug Administration", they can be found. It is legal and compliant, so you can choose to use it with confidence.
    Silicone oil is relatively common, and the first thing that comes to mind is polydimethylsiloxane, which is a relatively common but very common skin care oil in skin care products. Some big brands are in use, very cost-effective. For example: Annessa Sunscreen Lotion, Lancome New Essence Skin Base, Biore Aqua Sunscreen Moisturizing Gel, Clarins Clear Sunscreen, etc. Silicone oil mainly has the following functions in cosmetics.
