Abstract

Compositions for coloring skin are described. The compositions comprise beads that comprise petrolatum and optionally a colorant and the beads have a diameter from about 90 to about 625 microns. When applied topically, the compositions unexpectedly yield long lasting color.

First claim

What is claimed:

1. A composition for topical application, the composition comprising:
(a) a bead consisting of
(i) a hydrophobic composition, wherein 75 to 100% by weight of the hydrophobic composition is petrolatum; and
ii) colorant, wherein the colorant is selected from the group consisting of titanium dioxide, zinc oxide, iron oxide, organic lake, dye, chromium oxide, lycopene or mixtures thereof;
(b) a cosmetically acceptable carrier comprising at least 0.8% by weight of C 16 to C 20 fatty acid and salts thereof;
wherein:
the bead has a diameter from 90 to 625 microns, an h+c/a ratio that is from 0.02 to 0.5; the C 16 to C 20 fatty acid has a mixture of C 16 :C 20 fatty acid at weight ratio of about 60:40 to about 40:60;
the composition for topical application is a water-in-oil emulsion comprising from about 1 to about 99% by weight water; and
the colorant makes up from 0.01 to 0.15% by weight of the total weight of the composition for topical application.

2. The composition according to claim 1 wherein the bead has a diameter from 175 to 325 microns.

3. The composition according to claim 1 wherein the hydrophobic composition consists of petrolatum and one or more of sorbitol, glycerin, siliconized beeswax, siliconized shea butter, siliconized candelilla, siliconized carnauba, sunflower oil, safflower oil, or soybean oil.

4. The composition according to claim 1 wherein the bead has a melting point from 40° to 50° C.

5. The composition according to claim 1 wherein the colorant is selected from the group consisting of titanium dioxide, iron oxide, and zinc oxide.

6. The composition according to claim 2 wherein the h+c/a ratio is from 0.03 to 0.3.

7. The composition according to claim 1 wherein the colorant is iron oxide red.

8. The composition according to claim 1 wherein the colorant is a particle or agglomerate having a diameter from 100 to 1200 nm.

9. The composition according to claim 1 wherein the colorant is present and makes up from 0.01 to 0.06% of the composition.

10. The composition according to claim 1 wherein the hydrophobic composition makes up from 1 to 4% by weight of the composition.

11. The composition according to claim 1 wherein the composition further comprises sunscreen, niacinamide, 4-ethyl resorcinol, 4-hexyl resorcinol 4-phenylethyl recorsinol, petroselinic acid conjugated linoleic acid, tocophenyl acetate, tocopheryl palmitate, tocopheryl linoleate or retinol palmitate.

12. The composition according to claim 1 wherein the composition is a vanishing cream and water makes up from about 35% to about 80% by weight of the composition.

13. A method for coloring skin, the method comprising the step of contacting skin with the composition for topical application of claim 1 .

14. The composition according to claim 1 wherein the bead has a diameter from about 150 to about 450 microns, the composition comprising niacinamide and having a pH from about 4 to about 8, and further wherein the hydrophobic composition comprising petrolatum makes up from about 1 to about 3.5% by weight of the composition for coloring skin.

15. The composition according to claim 1 wherein the bead has a diameter from about 175 to about 325 microns and the composition comprises a resorcinol, sunscreen or retinol palmitate, and phenoxyethanol.
