Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, specifically to a composite silicone elastomer composition, a base makeup cosmetic, and a method for preparing the same. Background Technology

[0002] Currently, facial cosmetics are broadly categorized into skincare and makeup. Base makeup products, as a crucial part of makeup, aim to brighten skin tone, conceal blemishes, and give the skin a natural, flawless finish. These products typically consist of emollients, thickeners, pigments, film-forming agents, moisturizing ingredients, emulsifiers, preservatives, solvents, and various active ingredients. Additionally, silicone elastomers, or organosilicon elastomers, are polymers with a three-dimensional network structure. The application of silicone elastomers in cosmetics primarily offers benefits such as soft-focus effects, concealing pores and imperfections, and providing a soft touch.

[0003] However, it usually requires very high concentrations to provide a significant soft-focus effect, which results in a thick formula that may affect the skin's normal breathing and metabolic functions, and is also expensive. Summary of the Invention

[0004] To address the problems in the prior art, the first aspect of the present invention provides a composite silicon elastomer composition comprising: silica, polymethylsilsesquioxane, a siloxane crosslinking polymer, and isododecane.

[0005] In one embodiment, the mass ratio of silica, polymethylsilsesquioxane, siloxane crosslinked polymer, and isododecane is (0.5-1.5):(1-2):(0.6-1):(1.5-2). Examples include 0.5:1:0.6:1.5, 0.7:1.8:0.8:2, 0.9:1.3:0.75:1.5, 1:1.5:0.9:2, and 1.5:2:1:2.

[0006] In one embodiment, the siloxane crosslinking polymer includes at least one of polydimethylsiloxane / vinyl polydimethylsiloxane crosslinking polymer and vinyl polydimethylsiloxane / polymethylsilsesquioxane crosslinking polymer.

[0008] The applicant's inventive research has found that when the components of the composite silicone elastomer composition include silica, polymethylsilsesquioxane, siloxane crosslinking polymer, and isododecane, and the siloxane crosslinking polymer includes polydimethylsiloxane / vinyl polydimethylsiloxane crosslinking polymer and vinyl polydimethylsiloxane / polymethylsilsesquioxane crosslinking polymer, their synergistic effect can significantly improve the soft-focus performance of cosmetics, thereby solving the problem in existing color makeup technologies where soft-focus effect, improved skin feel, and reduced cost cannot be achieved simultaneously. In particular, when the mass ratio of silica, polymethylsilsesquioxane, siloxane crosslinking polymer, and isododecane is (0.5-1.5):(1-2):(0.6-1):(1.5-2), and the mass ratio of polydimethylsiloxane / vinyl polydimethylsiloxane crosslinking polymer and vinyl polydimethylsiloxane / polymethylsilsesquioxane crosslinking polymer is (0.3-0.5):(0.3-0.5), adding this composite silicone elastomer composition to base makeup products can effectively improve pore appearance.
