Cosmetic Composition
Cosmetic composition providing a high coverage of skin while retaining a natural skin appearance comprising iron oxide particles having an average surface area from 30 m 2 /g to 150 m 2 /g, iron-containing titanium dioxide particles having an average surface area from 1 m 2 /g to 30 m 2 /g 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.
1 . A cosmetic composition comprising:
(a) iron oxide particles having an average surface area from about 30 m 2 /g to about 150 m 2 /g;
(b) iron-containing titanium dioxide particles having an average surface area from about 1 m 2 /g to about 30 m 2 /g and comprising from about 1% to about 15% iron by weight of the titanium dioxide; and,
(c) a cosmetically acceptable carrier.
2 . The composition of claim 1 , wherein the iron-containing titanium dioxide particles have an average surface area of from about 1 m 2 /g to about 20 m 2 /g.
3 . The composition of claim 1 , wherein the iron-containing titanium dioxide particles comprise from about 5% to about 10% iron by weight of the titanium dioxide.
4 . The composition of claim 1 , wherein the iron-containing titanium dioxide particles have an average primary particle size of at least about 105 nm.
5 . The composition of claim 4 , wherein the iron-containing titanium dioxide particles have an average primary particle size from about 120 nm to about 500 nm.
6 . The composition of claim 1 , comprising from about 0.05% to about 20% iron-containing titanium oxide particles by weight of the total composition.
7 . The composition of claim, 1 comprising from about 1% to about 15% iron-containing titanium oxide particles by weight of the total composition.
8 . The composition of claim 1 , wherein the iron-containing titanium dioxide particles comprise a coating being substantially free of iron and wherein the iron is distributed throughout the titanium dioxide particles.
9 . The composition of claim 1 , wherein the iron oxide particles have an average surface area from about 50 m 2 /g to about 150 m 2 /g.
10 . The composition of claim 1 , wherein the iron oxide particles have an average primary particle size of less than or equal to about 100 nm.
11 . The composition of claim 1 , comprising from about 0.05% to about 10% iron oxide particles by weight of the total composition.
12 . The composition of claim 1 , wherein the cosmetically acceptable carrier is a water-in-silicone emulsion.
13 . The composition of claim 1 , comprising at least one hydrophobic organic sunscreen active being a cinnamic derivative.
14 . The composition of claim 13 , comprising 2-ethylhexyl-p-methoxycinnamate.
15 . The composition of claim 1 , comprising a cross-linked organopolysiloxane elastomer.
16 . Use of the composition of claim 1 as a cosmetic skin foundation.
17 . Use of the composition of claim 1 to correct skin discoloration surrounding the eye.
