Embodiment 1 to 5

[0108] The liquid foundation of the present invention is prepared as follows: In a suitable vessel, water, glycerin, disodium edetate and benzyl alcohol are added and mixed using conventional techniques until a clear aqueous phase is obtained. When the aqueous phase is clear, add the methylparaben and mix again until clear. The resulting phases were mixed at high speed (8,000 rpm, standard head) using a Silverson SL2T or similar equipment. In a separate container, add Dimethicone and Dimethicone Copolyol Crosspolymer, Cyclopentasiloxane, Pigment Dispersion, Other Oils, Dispersant, and Paraben ester and grind the mixture using a Silverson SL2T set on high speed until a homogeneous mixture is formed.

[0109] After this step, the aqueous and silicone phases were mixed and milled using a Silverson SL2T set to high speed until the water was fully incorporated and an emulsion formed. The dimethicone crosspolymer and cyclopentasiloxane were then added and the mixture was mixed aga...

Embodiment 6 to 10

[0114] Liquid foundations of the present invention are prepared by adding water, propylene glycol, methylparaben, sodium chloride and polyvinylpyrrolidone in a suitable vessel, heating and mixing using conventional techniques until a clear aqueous phase is obtained. The resulting phase was cooled to room temperature. In a separate container, add the cyclopentasiloxane, pigment dispersion, other oils, dispersants, propylparaben, ferrous titanium dioxide, clear iron oxide, and wax, and mix the mixture while heating. After the wax was evenly dispersed, the mixture was milled using a Silverson SL2T set to high speed and allowed to cool to 55°C as the powdered trihydroxystearin and linear siloxane were added. With both phases at room temperature, mix the aqueous and silicone phases and grind using a Silverson SL2T set to high speed until the water is completely incorporated and an emulsion is formed.

Abstract

Disclosed are processes for reducing the appearance of ashiness or pastiness on skin by applying a cosmetic composition comprising transparent iron oxide particles thereto, iron-containing titanium dioxide particles, and a cosmetically acceptable carrier. These processes are useful to provide coverage of skin imperfections and / or skin tonal variations and / or skin discoloration surrounding the eyes on different types of skin, while, at the same time, retaining a natural skin appearance.

Description

field of invention [0001] According to a first aspect, the present invention relates to a method of reducing the gray appearance of dark skin by applying to the skin a cosmetic composition comprising transparent iron oxide particles, iron-containing titanium dioxide particles and a cosmetically acceptable carrier. According to a second aspect, the present invention is directed to a method of reducing the bluish appearance of light-toned skin by applying to the skin a cosmetic composition comprising transparent iron oxide particles, iron-containing titanium dioxide particles and a cosmetically acceptable carrier. The method according to the present invention can be used to provide concealment of skin imperfections and / or differences in skin tone and / or skin discoloration around the eyes for different types of skin while maintaining a natural skin appearance. Background of the invention [0002] Consumers employ methods of applying cosmetic compositions to the skin to regulate...
