Alkaline hair conditioning compositions containing cationic guar
First Claim
1. A stable viscous hair relaxer, waving or curling composition having hair conditioning activity comprising a mixture of at least one alkaline earth metal hydroxide that relaxes strands of hair;
- and a hair conditioning amount of at least one cationic guar, said cationic guar being stable in the composition over time, and a cosmetically acceptable vehicle therefor, said composition having a pH of 12 to 14, said cationic guar being a polygalactomannan comprising mannose and galactose having at least one quaternary ammonium compound reacted therewith, said quaternary ammonium compound having the structure;
##STR5## wherein R1, R2, and R3 are alkyl, aryl and substituted alkyl and aryl groups;
R4 is selected from the group consisting of epoxyalkyl and halohydrin, and Z-- is an anion.

Abstract
The invention provides compositions for relaxing and conditioning keratinous fibers, particularly human hair. The compositions of the present invention have a high pH, i.e., a pH greater than 10, preferably, in the range of about 11 to about 14, more preferably about 12 to about 13.5, and include as a conditioning additive a cationic guar. Surprisingly, the cationic guar maintains stability, viscosity and activity over time in the highly alkaline pH of the inventive hair relaxer and conditioning compositions of the present invention. The relaxer compositions of the present invention afford beneficial effects to the user, such as softness and ease of wet combing, and cause less damage to hair following application and use. In addition, the conditioning relaxer compositions of the present invention remain on the hair and provide lasting conditioning and relaxing effects after one or more shampoos.
