Cosmetic composition having increased skin contact and makeup persistence and method of manufacturing same
Disclosed are a cosmetic composition having increased skin contact and makeup persistence and a method of manufacturing the same. The method includes: forming a powder continuous phase by rapidly mixing a powder and a film-forming agent; and obtaining a cosmetic composition in which a surface of the powder is compounded with the film-forming agent by heating the powder continuous phase for a predetermined time. In an embodiment, the cosmetic composition is manufactured by the method. In an embodiment, the cosmetic composition includes 5 wt % to 30 wt % of a powder, 0.1 wt % to 10 wt % of a film-forming agent, 10 wt % to 30 wt % of a silicone oil, and 0.1 wt % to 10 wt % of a spherical powder.
1. A method of manufacturing a cosmetic composition having increased skin contact and makeup persistence, comprising:
forming a powder continuous phase by mixing a powder and a film-forming agent; and
obtaining a cosmetic composition in which a surface of the powder is compounded with the film-forming agent by heating the powder continuous phase for a predetermined time,
wherein the forming the powder continuous phase comprises:
forming a first powder continuous phase activated with a weakly acidic region by placing 90 wt % to 99.5 wt % of the powder in a reactor, followed by addition with a powder activation solvent with stirring at 300 rpm to 700 rpm; and
forming a second powder continuous phase by adding the first powder continuous phase with 0.5 wt % to 10 wt % of the film-forming agent with stirring at 200 rpm to 400 rpm.
2. The method of claim 1 , further comprising homogenizing the cosmetic composition through pulverization and filtration.
3. The method of claim 1 , wherein the obtaining the cosmetic composition comprises performing heating at a reaction temperature of 60° C. to 120° C. for 0.5 hr to 24 hr.
4. The method of claim 2 , wherein the homogenizing comprises performing pulverization using a pulverizer of 3HP or more and filtration with 20 to 100 mesh.
5. The method of claim 1 , wherein the powder is at least one selected from the group consisting of talc, kaolin, mica, sericite, nylon-12, methyl methacrylate crosspolymer, polymethyl methacrylate, boron nitride, alumina, titanium dioxide, zinc oxide, iron oxide, silica, pearl, organic dye, lake pigment, organic pigment and mixtures thereof.
6. The method of claim 1 , wherein the film-forming agent is at least one selected from the group consisting of acrylate/dimethicone copolymer, acrylate/stearyl acrylate/dimethicone methacrylate copolymer, acrylate/ethylhexyl acrylate/dimethicone methacrylate copolymer, trimethylsiloxysilicate/dimethiconol crosspolymer, and mixtures thereof.
