1 results about "Cyclomethicone" patented technology

Cyclomethicone is a volatile methyl siloxane which makes up a class of liquid silicones that possess the characteristics of low viscosity and high volatility as well as being skin emollients and in certain circumstances useful cleaning solvents. Unlike dimethicones, which are linear siloxanes that do not evaporate, cyclomethicones are cyclic: both groups consist of a polymer featuring a monomer backbone of one silicon and two oxygen atoms bonded together, but instead of having a very long "linear" backbone surrounded by a series of methyl groups, cyclomethicones have short backbones that make closed or nearly-closed rings or "cycles" with their methyl groups, giving them many of the same properties of dimethicones but making them much more volatile. They are used in many cosmetic products where eventual complete evaporation of the siloxane carrier fluid is desired. In this way they are useful for products like deodorants and antiperspirants which need to coat the skin but not remain tacky afterward. Most cyclomethicone is manufactured by Dow Corning.

Barium sulfate-containing skin care product capable of blocking ultraviolet radiation

PendingCN114533585ACosmetic preparationsToilet preparationsWave bandCyclomethicone
The invention relates to the technical field of skin care products, and discloses a barium sulfate-containing skin care product capable of blocking ultraviolet radiation. Comprising the following raw materials in parts by weight: 1-5 parts of an antibacterial agent, 3-8 parts of zinc oxide, 2-6 parts of barium sulfate, 5-10 parts of cyclomethicone, 1-5 parts of cetyl-PG hydroxyethyl palmitamide, 2-8 parts of an emulsifier, 5-10 parts of an anti-caking agent and 2-5 parts of aluminum hydroxide. According to the barium sulfate-containing skin care product capable of blocking ultraviolet radiation, the barium sulfate is added, the barium sulfate has certain concealing force and oil and water absorption characteristics and also has a good sunscreen function, the zinc oxide, the aluminum hydroxide and the titanium dioxide are added, and the aluminum hydroxide can form a refraction layer to help skin to reflect UV rays, so that the skin is protected against ultraviolet radiation. Aluminum hydroxide can be used as an ultraviolet light absorber, UVA and UVB are resisted in a reflection mode, the protection wave band of titanium dioxide is about 290-400 nm and belongs to full-wave-band protection, the UVAI wave band is weak in performance, and the overall ultraviolet radiation blocking effect is good.
