The invention discloses a hydrophilic elastic powder and a preparation method and application thereof. The addition reaction between hydrogen-containing polysiloxane (hydrogen-containing silicone oil) and a divinyl end-capped unsaturated compound is used to form a cross-linked polymer , in the presence of a dispersant, the cross-linked polymer will form a powder and precipitate out of the solvent, and then the silicone elastomer powder will be obtained through the steps of filtration and solvent removal. Silicone elastomer powder has no agglomeration phenomenon, and the powder is uniform. When used in daily care products and cosmetics, it can absorb skin oil, produce a soft focus effect, and also make the skin moist and soft, with better smoothness and powdery texture. |
