Hair coloring compositions and methods thereof

Abstract

A hair coloring composition that includes about 5 to 25 wt. % of a first monosaccharide having 2 to 4 carbon atoms, up to about 10 wt. % of a second monosaccharide having 2 to 4 carbon atoms, about 0.1 to 5 wt. % of a surfactant, and about 0.1 to 5 wt. % of a delivery agent, each based on a total weight of the hair coloring composition. A method for coloring hair, that involves applying the hair coloring composition onto the hair, and optionally applying heat to the hair at a dyeing temperature of 30 to 205° C.

         2 . The hair coloring composition of  claim 1 , wherein the first monosaccharide is dihydroxyacetone. 
     
     
         3 . The hair coloring composition of  claim 1 , wherein the second monosaccharide is erythrulose. 
     
     
         4 . The hair coloring composition of  claim 1 , which has about 5 to 10 wt. % of the first monosaccharide and about 0.001 to 1 wt. % of the second monosaccharide, each based on a total weight of the hair coloring composition. 
     
     
         5 . The hair coloring composition of  claim 1 , wherein a weight ratio of the first monosaccharide to the second monosaccharide is 10:1 to 1,000:1. 
     
     
         6 . The hair coloring composition of  claim 1 , wherein the surfactant is at least one nonionic surfactant selected from the group consisting of an alkyl pyranoside and a polyoxyalkylene ether of a fatty alcohol. 
     
     
         7 . The hair coloring composition of  claim 1 , wherein the surfactant is a mixture of decyl glucoside and ceteareth-25. 
     
     
         8 . The hair coloring composition of  claim 1 , wherein the delivery agent is a dianhydrohexitol, a C 1  to C 4  monoalkoxy substituted dianhydrohexitol, or a C 1  to C 4  dialkoxy substituted dianhydrohexitol. 
     
     
         9 . The hair coloring composition of  claim 1 , wherein the delivery agent is dimethyl isosorbide. 
     
     
         10 . The hair coloring composition of  claim 1 , further comprising
 about 60 to 90 wt. % of water, and   about 0.5 to 5 wt. % of an organic solvent, each based on a total weight of the hair coloring composition.   
     
     
         11 . The hair coloring composition of  claim 1 , further comprising at least one of the following additives:
 up to about 3 wt. % of a preservative,   up to about 3 wt. % of an acidulant,   about 1 to 10 wt. % of a conditioning agent, and   up to about 1 wt. % of a fragrance, each based on a total weight of the hair coloring composition.   
     
     
         12 . The hair coloring composition of  claim 1 , which has a pH of about 2 to 5. 
     
     
         13 . The hair coloring composition of  claim 11 , wherein the conditioning agent is present, and is glycerin. 
     
     
         14 . The hair coloring composition of  claim 1 , which is in the form of a foam. 
     
     
         15 . A method for coloring hair, comprising:
 applying the hair coloring composition of  claim 1  onto the hair.   
     
     
         16 . The method of  claim 15 , further comprising applying heat to the hair at a dyeing temperature of 30 to 205° C. 
     
     
         17 . The method of  claim 16 , wherein the dyeing temperature is 30 to 60° C. 
     
     
         18 . The method of  claim 16 , wherein the dyeing temperature is more than 60° C. and up to 205° C. 
     
     
         19 . The method of  claim 15 , wherein the hair coloring composition is in the form of a foam. 
     
     
         20 . The method of  claim 15 , wherein the hair coloring composition is not applied to skin.
