Cosmetic emulsions containing uncoated silicone elastomers and non silicone treated pigments
Disclosed are cosmetic compositions in the form of an emulsion that contain an uncoated silicone elastomer, a solvent for the elastomer, a non-silicone treated pigment and an emulsifier, methods of making the compositions, and methods of applying the compositions to a keratinous substrate or tissue.
1. A cosmetic composition in the form of an emulsion comprising:
i) a non-emulsifying, uncoated silicone elastomer, wherein said non-emulsifying, uncoated silicone elastomer is a dimethicone crosspolymer;
ii) a solvent for said elastomer;
iii) at least one non silicone treated pigment chosen from the group consisting of an amino acid-treated pigment, a perfluoro-treated pigment and a monoalkoxy triacyl titanate-treated pigment; and
iv) an emulsifier,
with the proviso that the cosmetic composition is free of any peptide and free of pigments treated with a silicone compound.
2. The cosmetic composition of claim 1 , wherein said solvent is selected from the group consisting of cyclopentasiloxane, dimethicone, polydimethylsiloxanes, phenyltrimethicone, and trimethyl pentaphenyl trisiloxane.
3. The cosmetic composition of claim 1 , wherein the cosmetic composition comprises about 0.1% to about 15% of said non-emulsifying, uncoated silicone elastomer based on the total weight of said composition.
4. The cosmetic composition of claim 1 , wherein said pigment is an amino acid-treated pigment.
5. The cosmetic composition of claim 4 , wherein said amino acid-treated pigment is an N-acyl-glutamine-treated pigment.
6. The cosmetic composition of claim 4 , wherein said amino acid-treated pigment is a disodium stearoyl glutamate-treated pigment.
7. The cosmetic composition of claim 1 , wherein said at least one pigment is a perfluoro-treated pigment.
8. The cosmetic composition of claim 7 , wherein said perfluoro-treated pigment is a pigment treated with a C9-C15 fluoroalcohol phosphate.
9. The cosmetic composition of claim 1 , wherein said at least one pigment is a monoalkoxy triacyl titanate-treated pigment.
10. The cosmetic composition of claim 9 , wherein said monoalkoxy triacyl titanate-treated pigment is an isopropyl triisostearoyl titanate-treated pigment.
11. The cosmetic composition of claim 1 , which comprises more than one treated pigment, each of which has a different color.
12. The cosmetic composition of claim 1 , wherein said at least one pigment comprises an iron oxide, a dioxide or an iron oxide and a dioxide.
13. The cosmetic composition of claim 12 , wherein said dioxide is titanium dioxide, and said iron oxide is yellow iron oxide, black iron oxide, red iron oxide or a mixture thereof.
14. The cosmetic composition of claim 1 , wherein said emulsifier is a silicone polyether.
15. The cosmetic composition of claim 1 , wherein said emulsifier is a polyalkoxylated silicone elastomer.
16. The cosmetic composition of claim 1 , further comprising water and/or a water-miscible solvent.
17. The cosmetic composition of claim 1 , further comprising a non-volatile oil.
18. The cosmetic composition of claim 1 , further comprising a sunscreen agent.
19. The cosmetic composition of claim 1 , wherein the cosmetic composition is in the form of a foundation.
20. A method of applying make-up to a keratinous substrate, comprising applying to the substrate a cosmetic composition according to claim 1 .
21. The method of claim 20 , wherein the substrate is skin.
22. A cosmetic composition in the form of an emulsion comprising:
i) a non-emulsifying, uncoated silicone elastomer, wherein said non-emulsifying, uncoated silicone elastomer a dimethicone crosspolymer;
ii) a solvent for said elastomer selected from the group consisting of cyclopentasiloxane, dimethicone, polydimethylsiloxanes, phenyltrimethicone, and trimethyl pentaphenyl trisiloxane;
iii) a pigment treated with a C9-C15 fluoroalcohol phosphate, wherein the pigment is an iron oxide pigment, iron dioxide pigment, or an iron oxide and dioxide pigment; and
iv) an emulsifier selected from the group consisting of a polyalkoxylated silicone elastomer and a silicone polyether;
with the proviso that the cosmetic composition is free of any peptide and free of pigments treated with a silicone compound.
23. The cosmetic composition of claim 20 , wherein
ii) the solvent for said elastomer is selected from the group consisting of cyclopentasiloxane and dimethicone;
iii) the at least one non silicone treated pigment is an amino acid treated pigment; and
iv) the emulsifier is selected from the group consisting of a polyalkoxylated silicone elastomer and a silicone polyether.
24. The cosmetic composition of claim 23 , further comprising glycerin.
