A composition for lanthionizing keratin fibers comprising at least one multivalent metal hydroxide and at least one cation exchange composition. The invention is also drawn to a method for lanthionizing keratin fibers to achieve relaxation of the keratinous fibers.
Composition for washing and/or conditioning keratinous matter, containing a silicone and an amphoteric polymer derived from diallyldialkylammonium and from an anionic monomer. Composition for washing and/or conditioning keratinous matter, characterised in that it contains, in an aqueous medium, a surface-active agent possessing detergent properties, at least one silicone which is insoluble in the medium and at least one copolymer derived from diallyldialkylammonium and from an anionic monomer.
The present invention relates to a no-mix hair relaxer formulation and methods of its use. The relaxer includes a synergistic combination of sodium hydroxide and lithium hydroxide and has a pH of between about 12.7 and about 13.2. These no-mix hair relaxers provide excellent hair straightening performance, in 30 minutes or less, with reduced irritation.
An improved highly alkaline hair straightening emulsion and a two component system for preparing the emulsion are provided. The emulsion employs a combination of strong nitrogenous organic base and alkali metal hydroxide in the presence of an alkaline earth metal cation. Neither the amount of the alkali metal hydroxide nor the amount of organic base present in the emulsion is sufficient by itself to effectively permanently straighten naturally curly hair. Alkaline earth metal hydroxides are characteristically ineffective as permanent hair straighteners. However, surprisingly, the combination is effective for achieving permanent straightening of hair within a treatment time of not more than about 30 minutes. In use, the emulsion also substantially avoids scalp skin irritation. Also, hair discoloration and hair breakage are minimized.
The present invention provides a composition for lanthionizing keratin fibers comprising at least one multivalent metal hydroxide and at least one complexing agent effective for dissociating said at least one multivalent metal hydroxide in sufficient quantity to effect lanthionization of said keratin fibers. In one embodiment, the complex that is formed between the complexing agent and a metal ion from the multivalent metal hydroxide is soluble in water. The invention is also drawn to a method for lanthionizing keratin fibers to achieve relaxation of the keratinous fibers.
