Water resistant, wear resistant, and decorative cosmetic for hair
View Patent ↗The invention refers to a cosmetic product for hairs and decorative cosmetic with particular water resistance and wear (transfer) resistance. The product comprises stabile mixture of a water-emulsifiable, film-forming agent; a rheology modifier; a pigment; a volatile organic solvent; an oil soluble polymeric film-former; a silicon resin; and a filler.
1. A method for making a water-resistant cosmetic gel, comprising:
heating a mixture, comprising a water-emulsifiable, film-forming agent selected from one or more of an acrylate copolymer or acrylic or methacrylic acid or an ester thereof, a water-immiscible aliphatic hydrocarbon solvent, a non-ionic emulsifier and water in a range of 45 to 50 degrees Centiarade to make an emulsion;
mixing the emulsion with a volatile organic solvent to form a mixture having an organic phase and an aqueous phase;
homogenizing the mixture until the organic phase is distributed in the aqueous phase; and cooling the mixture until a homogeneous, water-resistant cosmetic gel is formed.
2. The method for making the cosmetic gel of claim 1 , wherein the mixture with an acrylate comprises 1-45% by weight of the film-forming agent on the basis of an acrylate copolymer or acrylic or methacrylic acid or an ester thereof which agent is emulsifiable with water.
3. The method for making the cosmetic gel of claim 1 , wherein the mixture comprises 0.01-35% by weight of an aliphatic hydrocarbon solvent or a volatile silicone derivate, both of which are not miscible with water and are emulsifiable with water-based ingredients and/or with ingredients on the basis of organic solvents in the presence of an emulsifier.
4. The method for making the cosmetic gel of claim 1 , wherein the mixture comprises 0.1-2% by weight of a non-ionic emulsifier.
5. The method for making the cosmetic gel of claim 1 , wherein the mixture comprises 1-30% by weight of water.
6. The method for making the cosmetic gel of claim 1 , wherein the emulsifier is chosen from the group consisting of alkoxylated alcohols, ethoxylated alcohols, polyglyceryl esters and mixtures thereof.
7. The method for making the cosmetic gel of claim 1 , wherein the acrylate copolymer comprises an ethyl acrylate/methyl methacrylate copolymer.
8. The method for making the cosmetic gel of claim 1 , wherein the film-forming agent is an ethyl acrylate/methyl methacrylate copolymer in which the ratio of ethyl acrylate units to methyl methacrylate units in the polymer is in the range of 7.5-8.5:1.8-2.3.
9. The method for making the cosmetic gel of claim 1 , the gel having an elasticity that is four to five times greater than elasticity of the film-forming agent used to make the gel.
10. A lip coloring agent made by the method of claim 1 .
11. A cream blush made by the method of claim 1 .
12. A cosmetic foundation made by the method of claim 1 .
13. A make-up made by the method of claim 1 .
14. A cream eyeshadow made by the method of claim 1 .
15. A concealer made by the method of claim 1 .
16. A mascara made by the method of claim 1 .
17. An eye cosmetic made by the method of claim 1 .
18. A temporary eyelash hair coloring made by the method of claim 1 .
19. A temporary hair coloring comprising the cosmetic gel of claim 1 .
