preparation example Construction

[0055] The second aspect of the present invention provides a method for preparing a silicon powder composite gel with oil control, protection and moisturizing effects, comprising the following steps: mixing the above-mentioned preparation raw materials at 70-80°C, and shearing by a high-speed shearing machine , that is.

[0056] Mechanism Explanation: The inventors have found through long-term research that the phenyl silicone oil and polymethylsilsesquioxane in the present invention form a synergistic effect, and the phenyl polytrimethylsiloxane has a light and soft skin feel, high refractive index High rate of oil, slippery but not greasy, can effectively improve the stickiness and brightness of the product; polymethylsilsesquioxane has good smoothness, helps the product maintain a good color, and then improves the moisturizing, refreshing and non-sticky Effect. Dimethicone / Vinyl Dimethicone Crosspolymer forms a synergistic combination with Dimethicone to help improve moist...

Embodiment 1

[0060] Embodiment 1 provides a silicon powder composite gel with oil control, protection and moisturizing effect, including the following preparation raw materials in parts by weight: 20 parts of polydimethylsiloxane, 20 parts of phenyl silicone oil, polydimethylsiloxane / Vinyl polydimethylsiloxane crosspolymer 30 parts, polysilsesquioxane 20 parts, regulator 8 parts, plasticizer 2 parts.

[0061] The polydimethylsiloxane is Dow Corning's PMX200, which has a viscosity of 20 mPa·s at 25°C.

[0062] The phenyl silicone oil is phenyl polytrimethicone.

[0063] The phenyl polytrimethicone is IOTA-255 from Anhui Aiyota Silicone Oil Co., Ltd.

[0064] The polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer is ZP-701 of Guangzhou Zhengpu Chemical Co., Ltd.

[0065] The polysilsesquioxane is polymethylsilsesquioxane.

[0066] The polymethylsilsesquioxane is a spherical fine powder with a particle diameter of 5 μm.

[0067] The polymethylsilsesquioxane is ZPF-509 o...

Embodiment 2

[0076] Example 2 is basically the same as Example 1, the only difference is that it includes the following preparation raw materials in parts by weight: 15 parts of polydimethylsiloxane, 15 parts of phenyl silicone oil, polydimethylsiloxane / vinyl polydimethicone 25 parts of methylsiloxane crosslinked polymer, 15 parts of polysilsesquioxane, 5 parts of regulator, and 1 part of plasticizer.

Abstract

The invention relates to the technical field of organic silicon elastomers, in particular to silicon powder composite gel with oil control, protection and moistening effects and a preparation method of the silicon powder composite gel. The silicon powder composite gel comprises the following preparation raw materials in parts by weight: 15-25 parts of polydimethylsiloxane, 15-25 parts of phenyl silicone oil, 25-35 parts of a polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer, 15-25 parts of polysilsesquioxane, 5-15 parts of a regulator and 1-5 parts of a plastic forming agent. The silicon powder composite gel with the oil control, protection and moistening effects has lasting silky skin touch, is used in systems such as lipsticks, and has good repairing capacity for lip problems such as dry wrinkles, dryness and roughness; and the silicon powder composite gel can significantly enhance lip elasticity, fade wrinkles, relieve skin roughness, improve lip gloss, significantly repair skin barriers, and moisturize the skin.

Description

technical field [0001] The invention relates to the field of composite application of silicon powder, and more specifically, the invention relates to a silicon powder composite gel with oil control, protection and moisturizing effects and a preparation method thereof. Background technique [0002] Silicone elastomers refer to silicon-containing polymers with different network crosslinking structures. According to different states, it can be divided into: silicone elastomer powder, silicone elastomer emulsion, silicone elastomer gel. The mixture of dimethylsiloxane crosslinked polymer and diluent, called silicone elastomer gel, is a mixture of silicone crosslinked polymer with three-dimensional network structure and small molecule solvent. Silicone elastomer gel can give the skin a unique "velvety" skin feel, so it is widely used in the fields of daily cosmetics such as skin care, make-up, and deperspirants. However, the silicone elastomer gels currently available on the ma...
