Transfer resistant cosmetic
View Patent ↗Provided are cosmetic compositions comprising acrylate film forming polymers and an surface-treated colorants which exhibit an improved or synergistic reduction in their propensity to transfer or rub of during wear.
1. A transfer-resistant cosmetic composition comprising: a combination of (i) a silicone acrylate film forming polymer; (ii) a particulate colorant comprising an alumina platelet having a top face and a bottom face and an average thickness of less than 0.5 microns and an average diameter between 1 and 20 microns, having a first colorant comprising a pigment or lake bonded to the top and bottom faces by treatment with triethoxy caprylylsilane; and (iii) a cosmetically acceptable vehicle; wherein the silicone acrylate film forming polymer and the particulate colorant are present in amounts to provide a synergistic enhancement in transfer resistance.
2. The cosmetic composition of claim 1 , wherein said treatment with triethoxy caprylylsilane is from about 0.5 wt % to about 2.0 wt % by weight of the particulate colorant.
3. The cosmetic composition of claim 1 , wherein the silicone acrylate film forming polymer is selected from the group consisting of butyl acrylate/hydroxypropyldimethicone acrylate copolymer, acrylate/dimethicone copolymer, acrylates/ethylhexyl acrylate/dimethicone methacrylate, and a combination thereof.
4. The cosmetic composition of claim 1 , wherein the silicone acrylate film forming polymer comprises butyl acrylate/hydroxypropyldimethicone acrylate copolymer.
5. The cosmetic composition of claim 1 , wherein the silicone acrylate film forming polymer comprises acrylate/dimethicone copolymer.
6. The cosmetic composition of claim 1 , wherein the silicone acrylate film forming polymer comprises acrylates/ethylhexyl acrylate/dimethicone methacrylate.
7. The cosmetic composition according to claim 1 , wherein the composition is in the form of a lipstick or lip gloss.
8. The cosmetic composition according to claim 1 , wherein the composition is in the form of a mascara or hair product.
9. The cosmetic composition according to claim 1 , wherein the alumina platelet has an edge and the first colorant is adhered to the top and bottom surfaces of the alumina platelet by said treatment with triethoxy caprylylsilane; wherein about 5% to about 90% of the surface area of said platelet is coated with said first colorant and wherein the edge of the platelet is substantially free of said first colorant.
10. The composition of claim 9 , wherein the first colorant comprises a pigment.
11. The composition of claim 9 , wherein the first colorant comprises a lake.
12. The composition of claim 9 , wherein the first colorant has a weight percentage of about 15% to about 60% of the total combined weight percentage of the first colorant and the alumina platelet.
13. The composition of claim 9 , wherein the first colorant has a weight percentage of about 15% to about 35% of the total combined weight percentage of the first colorant and the alumina platelet.
14. The composition of claim 9 , wherein the first colorant has a weight percentage of about 35% to about 55% of the total combined weight percentage of the first colorant and the alumina platelet.
15. The cosmetic composition of claim 9 , wherein said cosmetically acceptable vehicle comprises a silicone fluid having a viscosity of less than 1 cSt at 25° C.
16. A lip stick or lip gloss comprising the cosmetic composition of claim 9 .
