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

[0113] 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 vessel, add the cyclopentasiloxane, pigment dispersion, other oils, dispersants, propylparaben, ferric 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

Cosmetic composition providing a high coverage of skin while retaining a natural skin appearance comprising iron oxide particles having an average primary particle size of less than or equal to 100 nm, iron-containing titanium dioxide particles having an average primary particle size of at least 105nm and comprising from 1% to 15% iron by weight of the titanium dioxide, and a cosmetically acceptable carrier and its use as a foundation and / or as a composition to correct skin discoloration surrounding the eye.

Description

field of invention [0001] According to a first aspect, the present invention relates to a cosmetic composition comprising transparent iron oxide particles, iron-containing titanium dioxide particles, and a cosmetically acceptable carrier. According to a second aspect, the invention relates to the use of this composition as a foundation. According to a third aspect, the invention relates to the use of the composition for correcting dark circles around the eyes. Cosmetic compositions according to the present invention are useful for concealing skin imperfections while maintaining a natural skin appearance.
