Abstract
A composition for lanthionizing keratin fibers comprising at least one hydroxide compound, with the proviso that said at least one hydroxide compound is not sodium hydroxide, lithium hydroxide or potassium hydroxide; and at least one activating agent chosen from cysteine-based compounds; and methods and kits for use thereof.
Claims26
A method for lanthionizing keratin fibers to achieve a desired relaxation comprising:
- (a) storing a first composition,
- (b) storing a second composition separately from said first composition,
- (c) combining said first composition with said second composition, and
- (d) applying said composition to said keratin fibers for a sufficient period of time to achieve a desired relaxation,
- wherein said first composition comprises at least one activating agent chosen from cysteine-based compounds and optionally at least one entity chosen from:
- (1) at least one compound capable of being converted in situ to at least one soluble base;
- and
- (2) at least one hydroxide compound with the proviso that said at least one hydroxide compound is not sodium hydroxide, lithium hydroxide or potassium hydroxide;
- and wherein said second composition comprises at least one entity chosen from:
- (1) at least one compound capable of being converted in situ to at least one soluble base;
- and
- (2) at least one hydroxide compound with the proviso that said at least one hydroxide compound is not sodium hydroxide, lithium hydroxide or potassium hydroxide,
- with the proviso that said at least one compound capable of being converted in situ to at least one soluble base and at least one hydroxide compound are present, together or separately, in at least one composition chosen from said first composition and said second composition.

A method for lanthionizing keratin fibers comprising:
- (a) storing a first composition,
- (b) storing a second composition separately from said first composition,
- (c) storing a third composition separately from said first composition and said second composition,
- (d) combining said first composition with said second composition and said third composition, and
- (e) applying said composition to said keratin fibers for a sufficient period of time to achieve a desired relaxation,
- wherein said first composition comprises at least one activating agent chosen from cysteine-based compounds,
- wherein said second composition is chosen from at least one compound capable of being converted in situ to at least one soluble base, and
- wherein said third composition comprises at least one hydroxide compound, with the proviso that said at least one hydroxide compound is not sodium hydroxide, lithium hydroxide or potassium hydroxide.

A multicompartment kit for lanthionizing keratin fibers to achieve relaxation of said keratin fibers comprising at least three compartments,
- wherein a first compartment comprises at least one hydroxide compound, with the proviso that said at least one hydroxide compound is not sodium hydroxide, lithium hydroxide or potassium hydroxide,
- wherein a second compartment comprises at least one compound capable of being converted in situ to at least one soluble base, and
- wherein a third compartment comprises at least one activating agent chosen from cysteine-based compounds.
A multicompartment kit for lanthionizing keratin fibers to achieve relaxation of said keratin fibers comprising at least two compartments,
- wherein a first compartment comprises at least one activating agent chosen from cysteine-based compounds and optionally at least one entity chosen from:
- (1) at least one compound capable of being converted in situ to at least one soluble base;
- and
- (2) at least one hydroxide compound, with the proviso that said at least one hydroxide compound is not sodium hydroxide, lithium hydroxide or potassium hydroxide;
- and
- wherein a second compartment comprises at least one entity chosen from:
- (1) at least one compound capable of being converted in situ to at least one soluble base;
- and
- (2) at least one hydroxide compound, with the proviso that said at least one hydroxide compound is not sodium hydroxide, lithium hydroxide or potassium hydroxide;
- with the proviso that said multicompartment kit comprises at least one activating agent, at least one compound capable of being converted in situ to at least one soluble base and at least one hydroxide compound.
