Abstract
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.
Claims25
A water-resistant cosmetic gel, comprising:
- a stable 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;
- a cosmetic wax;
- a rheology modifier;
- a pigment phase, comprising mineral pigments, organic pigments, pearl pigments, surface-coated pigments and mixtures thereof;
- a volatile organic solvent;
- an oil soluble polymeric film-former;
- a silicon resin;
- and
- a filler.
A cosmetic gel comprising a stable mixture comprising ethyl acrylate and methyl methacrylate in a concentration of about 24.5% by weight of the gel and isododecane in a concentration of about 50% by weight of the gel.
A method for imparting elasticity and softness to a cosmetic, comprising:
- providing a film-forming agent comprising an acrylate copolymer or acrylate derivative and a non-ionic emulsifier to form a mixture;
- heating the mixture to a temperature of 45 to 50 degrees Centigrade to form an emulsion;
- mixing the emulsion with a volatile aliphatic hydrocarbon solvent or a volatile silicone derivate and homogenizing to form a two-phase liquid system;
- cooling the two-phase liquid system with rapid mixing to form a homogeneous gel;
- and
- mixing the gel with a cosmetic formulation to soften and increase elasticity of the cosmetic formulation.
