1. A two-component hair relaxer system for producing an alkaline hydroxide relaxer for relaxing hair comprising:
- (a) a first component comprising a water-containing cream base containing a water-soluble salt of a relatively strong base selected from the group consisting of quanidine and N-methyl guanidine with an anion capable of being precipitated by an alkaline earth metal ion under highly alkaline conditions, and(b) a second, separate component, which is substantially free of water, and containing an alkaline material which is an alkaline earth metal hydroxide, an alkaline earth metal oxide, or a mixture thereof having an alkaline earth metal ion which forms a precipitate with the anion when the first component and second component are mixed.

Abstract
The present invention relates to a two-component hair relaxer system comprising (a) a first component comprising a cream base containing a water-soluble salt of a relatively strong base with an anion capable of being precipitated by an alkaline earth metal ion under highly alkaline conditions, and (b) a second, separate component, which is substantially free of water, and containing an alkaline material having an alkaline earth metal ion which forms a precipitate with the anion when the first component and second component are mixed.

48. A two-component hair relaxing system for producing an alkaline hydroxide relaxer for relaxing hair comprising:
-
(a) a first component comprising a liquid activator comprising a water-solution of a water-soluble salt of a relatively strong organic nitrogen containing base selected from the group consisting of guanidine and N-methyl guanidine with a carbonate anion and which is susceptible to alkaline hydrolysis and formation of ammonia, wherein the water-solution contains a carbonate/bicarbonate buffer to retard decomposition of the water-soluble salt and formation of ammonia, and (b) a cream base which contains an alkaline material which is an alkaline earth metal hydroxide having an alkaline earth metal ion which forms a precipitate with the carbonate anion, the first component when subsequently mixed with the second component reacting with the alkaline material to produce a hair relaxer composition. - View Dependent Claims (49, 50)
