  • Patent number: 6013249
    Abstract: A mild wave and hair styling reducing agent-containing composition and method of bodifying, styling, or permanently waving or straightening human hair that provides a strong, long lasting curl, or long lasting straight hair formation, while minimizing hair damage. The composition includes two ionic compounds, one cationic and the other anionic, that complex in solution over a molar ratio of cationic compound to anionic compound in the range of about 1:1.2 to about 1.2:1, preferably in the range of about 1:1.1 to about 1.1:1, to provide synergy in waving efficiency, thereby providing a strongly reconfigured hair configuration (curled or straightened). At least one of the ionic compounds functions as a reducing agent for hair, capable of breaking the disulfide bonds in the hair so that the bonds later can be reformed via oxidation, when the hair is in the desired configuration.
    Type: Grant

  • Patent number: 5728374
    Abstract: A mild permanent wave reducing agent-containing composition and method of permanently waving or straightening human hair that provides a strong, long lasting curl, or long lasting straight hair formation, while minimizing hair damage. The composition includes two ionic compounds, one cationic and the other anionic, that complex in solution over a molar ratio of cationic compound to anionic compound in the range of about 1:1.2 to about 1.2:1, preferably in the range of about 1:1.1 to about 1.1:1, to provide synergy in waving efficiency, thereby providing a strongly reconfigured hair configuration (curled or straightened). At least one of the ionic compounds functions as a reducing agent for hair, capable of breaking the disulfide bonds in the hair so that the bonds later can be reformed via oxidation, when the hair is in the desired configuration. Examples of cationic compounds include thiocholine, choline, cysteineamide, cysteamine, and combinations thereof.

Examples of cationic compounds include thiocholine, choline, cysteineamide, cysteamine, and combinations thereof. Examples of anionic compounds include cysteine, N-acetylcysteine, thioglycolic acid or its salts, and combinations thereof. The preferred ionic compounds are thiocholine and N-acetylcysteine.
