Hair Straightening Method Involving Reducing Sugars

Abstract

A hair straightening and/or hair relaxing method comprising: applying a hair care composition to hair, wherein the composition comprises a sugar, a buffering agent and a cosmetically acceptable carrier; and wherein, where the composition is heated to a temperature of at least 100° C., the composition comprises from about 6% to about 20% reducing sugar; hair drying; providing a hair straightening appliance at a temperature of from about 100° C. to about 280° C. and mechanically straightening the hair with the appliance.

What is claimed is: 
     
         1 . A composition for straightening hair comprising:
 from about 12% to about 18% reducing sugar, by weight of the formulation, wherein the reducing sugar is selected from the group consisting of: arabinose, ribose, and mixtures thereof;   a buffering agent;   a cosmetically acceptable carrier;   a conditioning agent being the reaction product of: (a) an aminosilane; (b) polysiloxane; and (c) a polyether;   and wherein the composition has a pH of from about pH 6 to about pH 10.   
     
     
         2 . The composition according to  claim 1 , wherein the conditioning agent is selected from the group consisting of epoxyaminosilane copolymers, polysiloxane/polyurea block copolymers, and mixtures thereof. 
     
     
         3 . The composition according to  claim 1 , wherein the reducing sugar is arabinose. 
     
     
         4 . The composition according to  claim 1 , wherein the buffering agent is selected from the group consisting of glycine/sodium hydroxide, sodium carbonate/sodium hydrogen carbonate, sodium tetraborate/sodium hydroxide, sodium bicarbonate/sodium hydroxide, ammonium chloride/ammonia, and mixtures thereof. 
     
     
         5 . The composition according to  claim 1 , wherein the composition has a pH of from about pH 6.5 to about pH 9.75. 
     
     
         6 . The composition according to  claim 1 , wherein the composition has a pH of from about pH 7.0 to about pH 9.5. 
     
     
         7 . The composition according to  claim 1 , wherein the composition has a pH of from about pH 8.0 to about pH 9.0. 
     
     
         8 . The composition according to  claim 1 , wherein the composition is substantially free of a quaternary ammonium compound and/or a surfactant. 
     
     
         9 . The composition according to  claim 1 , wherein the composition is substantially free of: ceramide compound, an alpha-hydroxy acid, a thioglycolate or thiolactate compound, a bisulfate compound, clay, a reducing agent. 
     
     
         10 . A kit for straightening hair comprising: (i) a composition according to  claim 1 ; (ii) a heating device comprising a flat iron. 
     
     
         11 . The kit according to  claim 10 , wherein the composition is a composition for straightening hair comprising:
 from about 12% to about 18% reducing sugar, by weight of the formulation, wherein the reducing sugar is arabinose;   a buffering agent;   a cosmetically acceptable carrier;   a conditioning agent being the reaction product of: (a) an aminosilane; and (b) polysiloxane;   
       and wherein the composition has a pH of from about pH 6 to about pH 10.
