Color cosmetic with high coverage and naturalness
View Patent ↗Described herein is a cosmetic composition comprising a mixture of metal oxide pigments having different shapes and sizes which provides high coverage and a natural look upon application.
1. A cosmetic composition comprising: (i) a first pigment component comprising metal oxide particles bonded to an alumina platelet by an alkyl silane; (ii) a second pigment component comprising metal oxide particles whose surface is modified with a surface treatment comprising isopropyl titanium triisostearate and a silane compound having a hydrophobic portion comprising dimethicone; and (iii) a crosslinked silicone elastomer gelling agent.
2. The cosmetic composition of claim 1 , wherein the weight ratio of said first pigment to said second pigment, is from about 1:5 to about 5:1.
3. The cosmetic composition of claim 1 , wherein said first pigment component comprises titanium dioxide particles.
4. The cosmetic composition of claim 3 , wherein the shape of said titanium dioxide particles is spherical.
5. The cosmetic composition of claim 1 , further comprising a light diffuser.
6. The cosmetic composition of claim 1 , further comprising particles of boron nitride.
7. The cosmetic composition of claim 1 , wherein the crosslinked silicone elastomer gelling agent comprises a cyclic epoxide crosslinker.
8. The cosmetic composition of claim 1 , wherein the crosslinked elastomer silicone gelling agent has the structure:
where R is a C 1 -C 20 hydrocarbon radical, x is from 2 to 4, m is from 1 to about 100, and n and o are from 0 to 100, with at least one of n or o being greater than zero.
9. The cosmetic composition of claim 1 , further comprising one or more additional iron oxide pigments.
10. A cosmetic foundation comprising the cosmetic composition of claim 1 , further comprising one or more of nylon powder, calcium carbamate, silica, bismuth oxychloride, and zinc oxide.
11. The cosmetic composition of claim 1 , wherein said composition does not comprise a film-former.
12. The cosmetic composition of claim 1 , wherein said first and second pigment components together comprise from about 5% to about 25% by weight of the composition.
13. The cosmetic composition of claim 1 , wherein the weight ratio of said first pigment to said second pigment, is from about 1:2 to about 2:1.
