application of powder treatment agents in cosmetics-cosmetic silicone oil manufacturer

in order to further improve the properties of the powder, high molecular weight dpms (dimethylpolysiloxane) is currently used to treat the surface of the powder. the powder has excellent hydrophobicity and high durability, has good make-up finish, and has good adhesion to the skin. , has a moderate stickiness and good usability. a new powder treatment method has been successfully developed in recent years. the new method is to contact cyclic methyl hydrogenated polysiloxane with the powder at a temperature below 100°c under normal pressure. due to the catalytic activity characteristics of the powder surface, a polymerization reaction can occur to form a network polymer. as a result, an ultra-thin film is formed on the powder surface. this film can introduce functional groups through addition reactions. if the introduced functional group is an alkyl group, a hydrophobic powder will be generated; if it is a hydroxyl group and a polyoxyethylene group, a hydrophilic powder will be generated.
