Abstract
Abstract Compositions and method for imparting shampoo resistant body and settability to human hair comprising the application of an aqueous solution containing a precondensate of glyceraldehyde and resorcinol under conditions promoting in situ polymerization. Tendency for yellowing of gray hair is substantially avoided by incorporation in the solution of urea.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
103 words
In a hair treating composition for imparting improved setting properties comprising an aqueous solution containing about 0.5 to 20% by weight of a mixture of glyceraldehyde, resorcinol, and an oligomeric precondensate of glyceraldehyde and resorcinol, said composition being prepared by heating an aqueous mixture containing glyceraldehyde, resorcinol, and an acid selected from the class consisting of boric acid and silicic acid, the molar ratio of glyceraldehyde to resorcinol being about 19:1 to 1:19 and the molar ratio of glyceraldehyde to said acid being about 4:1 to 1:1.5; wherein the improvement comprises including in said composition about 0.1% to 20% by weight of urea.
Claim 2
Dependent Claim
103 words
In a hair treating composition for imparting improved setting properties comprising an aqueous solution containing about 0.5 to 20% by weight of a mixture of glyceraldehyde, resorcinol, and an oligomeric precondensate of glyceraldehyde and resorcinol, said composition being prepared by heating an aqueous mixture containing glyceraldehyde, resorcinol, and an acid selected from the class consisting of boric acid and silicic acid, the molar ratio of glyceraldehyde to resorcinol being about 19:1 to 1:19 and the molar ratio of glyceraldehyde to said acid being about 4:1 to 1:1.5; wherein the improvement comprises including in said composition about 0.1% to 20% by weight of urea.
Claim 3
Dependent Claim
57 words
A hair treating composition as defined in claim 1, containing, in addition, a hydroxycarboxylic acid selected from the group consisting of tartaric, mandelic, salicylic and citric acids, the quantity of said hydroxycarboxylic acid being sufficient to reduce the pH of said composition to a level lower than the pH level imparted by said boric or silicic acid.
Claim 4
Dependent Claim
80 words
A hair treating composition as defined in claim 1, in which the molar ratio of glyceraldehyde to resorcinol is about 1:1, the molar ratio of glyceraldehyde to said acid is about 1:1, the concentration of urea is about 0.5% to 2% by weight, and containing, in addition, a hydroxycarboxylic acid selected from the group consisting of tartaric, mandelic, salicylic and citric acids, the quantity of said hydroxycarboxylic acid being sufficient to reduce the pH of said composition to about 1.6-1.8.
Claim 5
Dependent Claim
110 words
In a method of treating hair to impart improved setting properties, comprising the application of a composition comprising an aqueous solution containing about 0.5 to 20% by weight of a mixture of glyceraldehyde, resorcinol, and an oligomeric precondensate of glyceraldehyde and resorcinol, said composition being prepared by heating an aqueous mixture containing glyceraldehyde, resorcinol, and an acid selected from the class consisting of boric acid and silicic acid, the molar ratio of glyceraldehyde to resorcinol being about 19:1 to 1:19 and the molar ratio of glyceraldehyde to said acid being about 4:1 to 1:1.5, wherein the improvement comprises including in said composition about 0.1% to 20% by weight of urea.
Claim 6
Dependent Claim
110 words
In a method of treating hair to impart improved setting properties, comprising the application of a composition comprising an aqueous solution containing about 0.5 to 20% by weight of a mixture of glyceraldehyde, resorcinol, and an oligomeric precondensate of glyceraldehyde and resorcinol, said composition being prepared by heating an aqueous mixture containing glyceraldehyde, resorcinol, and an acid selected from the class consisting of boric acid and silicic acid, the molar ratio of glyceraldehyde to resorcinol being about 19:1 to 1:19 and the molar ratio of glyceraldehyde to said acid being about 4:1 to 1:1.5, wherein the improvement comprises including in said composition about 0.1% to 20% by weight of urea.
Claim 7
Dependent Claim
59 words
A method as defined in claim 4, in which said composition contains, in addition, a hydroxycarboxylic acid selected from the group consisting of tartaric, mandelic, salicylic, and citric acids, the quantity of said hydroxycarboxylic acid being sufficient to reduce the pH of said composition to a level lower then the pH level imparted by said boric or silicic acid.
Claim 8
Dependent Claim
80 words
A method as defined in claim 4, in which the molar ratio of glyceraldehyde to resorcinol is about 1:1, the molar ratio of glyceraldehyde to said acid is about 1:1, the concentration of urea is about 0.5% to 2%, and in which the composition contains, in addition, a hydroxycarboxylic acid selected from the group consisting of tartaric, mandelic, salicylic, and citric acids, the quantity of said hydroxycarboxylic acid being sufficient to reduce the pH of said composition to about 1.6-1.8.
Claim 9
Dependent Claim
103 words
In a method for the preparation of a hair treating composition for imparting improved setting properties, comprising heating an aqueous solution containing about 0.5 to 20% by weight of a mixture of glyceraldehyde and resorcinol and containing, in addition, an acid selected from the class consisting of boric acid and silicic acid to form an oligomeric precondensate of glyceraldehyde and resorcinol, the molar ratio of glyceraldehyde to resorcinol being about 19:1 to 1:19 and the molar ratio of glyceraldehyde to said acid being about 4:1 to 1:1.5; wherein the improvement comprises adding to said solution about 0.1% to 20% by weight of urea.
