Abstract:
Disclosed herein is a composition for the dyeing of keratin fibers, for example, human keratin fibers such as the hair, comprising at least one 3-amino pyrazolo-[1,5-a]-pyridine derivative or one of its addition salts and a method employing this derivative. The composition of the present disclosure makes it possible to obtain coloration in various shades that is powerful, chromatic, and aesthetic, with low selectivity and with good resistance to various aggressive factors to which the hair may be subjected, such as shampoos, the light, sweat and permanent shaping.
Abstract:
Disclosed herein are 2,6-disubstituted para-phenylenediamine compounds chosen from compounds of formula (I) and the salts and solvates thereof: Also disclosed herein are the corresponding intermediate compounds. Further disclosed herein is a composition for the oxidation dyeing of keratin fibers, for example, human keratin fibers such as the hair, comprising at least one para-phenylenediamine compound. Still further disclosed herein are oxidation dyeing processes comprising applying the composition to keratin fibers.
Abstract:
The present application relates to a novel family of double para-phenylenediamines joined by a linkage comprising a saturated cyclic radical and use thereof for the dyeing of keratin fibers. These novel para-phenylenediamines can be used as an oxidation base for the dyeing of keratin fibers. Methods of making and using, and a dyeing kit are also disclosed.
Abstract:
The present disclosure relates to novel N-alkylhydroxylated secondary para-phenylenediamine compounds, to a composition for dyeing keratin fibers, for instance human keratin fibers such as the hair, comprising, in a medium that is suitable for dyeing, at least one ortho- and/or meta-substituted N-alkylhydroxylated secondary para-phenylenediamine, to a process for dyeing keratin fibers comprising applying this composition, and also a dyeing “kit.”
Abstract:
The present disclosure relates to novel N-alkylamino secondary para-phenylenediamines; a composition for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising, in a medium suitable for dyeing, at least one such N-alkylamino secondary para-phenylenediamine; a process for dyeing keratin fibers comprising applying this composition; and the uses of this composition in the form of a dyeing “kit”.
Abstract:
