| titleOfInvention | a spherical porous silica and silicone elastomer hybrid powder and the method |
| abstract | TECHNICAL FIELD The present invention relates to a powder used for a cosmetic material, and more specifically, to a porous spherical silica and a silicone elastomer hybrid powder for cosmetics, which are particularly used for color cosmetics, and a process for producing the same. The present invention relates to a method for producing a polyvinylidene fluoride resin composition, which comprises vinyl-terminated polydimethylsiloxane polymers, methylhydrogensiloxane polymer, Cyclopentasiloxane or Dimethicone, And a platinum catalyst (Pt-Catalyst) to prepare a silicone elastomer reaction liquid (step 1) (Step 2) of immersing the porous spherical silica in the reaction solution and uniformly kneading the same to allow the reaction liquid to be homogeneously supported on the pores of the silica, (3) a step of inducing a chemical reaction by heat-treating the silicon mixed reaction solution supported on the porous spherical silica, The present invention provides a method for producing porous spherical silica and silicone elastomer hybrid powder. In addition, in the present invention, the above-mentioned step 1 may be carried out by mixing 10 to 80 parts by weight of a methylhydrogensiloxane polymer, 10 to 200 parts by weight of cyclopentasiloxane, And 1 to 10 parts by weight of a catalyst (Pt-Catalyst) are mixed to prepare a silicone elastomer reaction liquid. The porous spherical silica and the silicone elastomer hybrid powder are produced by the method. In the present invention, in the above step 1, 100 parts by weight of vinyl-terminated polydimethylsiloxane polymers, 40 to 80 parts by weight of methylhydrogensiloxane polymer, 100 to 200 parts by weight of dimethicone, And 1 to 10 parts by weight of a platinum catalyst (Pt-Catalyst) are mixed to prepare a silicone elastomer reaction liquid. The present invention also provides a porous spherical silica and a silicone elastomer hybrid powder produced by the above method. |
