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.
Claims18
A composition for topical application, the composition comprising:
- (a) a bead comprising
- (i) a hydrophobic composition comprising petrolatum;
- and
- (ii) optionally colorant;
- (b) a cosmetically acceptable carrier comprising at least 8% by weight of C16 to C20 fatty acid, the fatty acid being at least 32% by weight C18 fatty acid and including any salts thereof
- wherein the bead has a diameter from about 90 to about 625 microns and further wherein the h+c/a ratio is at least 0.02.
3 more elements
A method for making a composition for coloring skin, the method comprising, in no particular order, the steps of:
- (a) heating with or without colorant hydrophobic composition comprising petrolatum to a temperature from about 40° C. to about 65° C. to produce a heated hydrophobic composition;
- (b) heating cosmetically acceptable carrier comprising at least 8% by weight of C16 to C20 fatty acid, the fatty acid being at least 32% by weight C18 fatty acid and the cosmetically acceptable carrier being heated to a temperature from about 25° to about 48° C.;
- and
- (c) combining the heated hydrophobic composition and heated carrier to produce a carrier with a heated hydrophobic composition and mixing the carrier with heated hydrophobic composition until beads comprising hydrophobic composition comprising petrolatum and optionally colorant having a diameter from 90 to 625 microns are produced with the proviso that the temperature of the heated hydrophobic composition does exceed the temperature of the carrier.
