| titleOfInvention | SUITABLE GEL TECHNOLOGY FOR USE IN COSMETIC COMPOSITIONS |
| abstract | A gel system comprising a fractal network of nanoparticles and macroscopic particles is disclosed. The gel system is capable of forming an effective optical angel to attenuate lines and wrinkles as a result of differences in the size domain between fractal particles and macroscopic particles. Cosmetic compositions comprising such gels and methods for use are also disclosed. Claim 2: The cosmetic composition of claim 1, wherein the nanoparticles are inorganic nanoparticles having a particle size ranging from about 50 to 900 nanometers and a refractive index ranging from about 1.38 to about 2. Claim 3: cosmetic composition of claim 2 wherein the inorganic nanoparticles are silica, alumina, titania, zirconia, zinc oxide, doped tin oxide with indium, ceria, or mixtures thereof and where the macroscopic particles are selected from the group consisting of elastomers of sylicon; silicone crospolymers; hydrocarbon elastomers; natural and synthetic gums; polymer spheres or compatible combinations thereof. Claim 4: The composition of claim 3 wherein the polymer spheres are selected from the group consisting of fluoropolymers, polyacrylates, nylon, polyesters, cellulose capsules, polyurethanes, polyacrylic esters, polyethers, polyamides, polyurethanes polyurethanes and mixtures thereof. Claim 14: The cosmetic composition of claim 3 wherein the gel is an aqueous dispersion of the first nanoparticles and the second nanoparticles having a determined pH, and the first and second nanoparticles have zeta potentials of charges opposite to said pH. Claim 16: The cosmetic composition of claim 3 wherein the cosmetic composition is substantially anhydrous and the gel further comprises a non-aqueous solvent. Claim 21: A substantially anhydrous cosmetic composition comprising a gel comprising (a) a fractal network of nanoparticles; (b) translucent macroscopic particles and (c) a non-aqueous solvent, and the refractive index of the nanoparticles does not match the refractive index of the macroscopic particles. Claim 32: A method for optically attenuating the appearance of imperfections in the skin selected from the group consisting of wrinkles, expression lines and pores comprising the step of applying on the skin an amount of an effective skin care composition or makeup to optically attenuate the appearance of said imperfection in the skin, and the composition comprises a gel system comprising (a) a fractal network of nanoparticles; and (b) translucent macroscopic particles. |
