Abstract:
The present disclosure relates to a composition for dyeing human keratin fibers, comprising at least one cationic direct dye of formula (I), described herein, and at least one cosmetic agent chosen from thickening agents and surfactants. Also disclosed herein is a dyeing process comprising applying a composition of the present disclosure to keratin fibers, in the presence or absence of an oxidizing agent. Further disclosed herein is a multi-compartment device comprising at least one first compartment containing a dye composition of the present disclosure and at least one second compartment containing at least one oxidizing composition.
Abstract:
Disclosed herein is the use, in the coloring of keratinous fibers, such as human keratinous fibers, such as the hair, of a composition comprising at least one compound chosen from the compounds of formula (I) comprising a cyclic group G including a ring H capable of opening, the dyes corresponding to the compounds of formula (I) wherein the ring H is open, and the addition salts thereof: and a method for treating keratinous fibers employing this composition.
Abstract:
Disclosed herein is the use of at least one compound chosen from porphyrin compounds and phthalocyanin compounds for dyeing human keratin materials. Further, disclosed herein is a composition comprising, in a suitable dyeing medium, at least one compound from porphyrin compounds and phthalocyanin compounds as at least one direct dye, and also to a ready-to-use composition comprising this at least one direct dye. Furthermore, disclosed herein is a dyeing process using the composition or the ready-to-use composition, and also to a device for implementing this process. Finally, disclosed herein are phthalocyanin compounds.
Abstract:
The disclosure provides compositions comprising, in a cosmetically acceptable medium, at least one direct dye, processes for treating keratin fibers, such as human keratin fibers, using the compositions, and devices comprising the compositions. Use of the compositions as lightening agents and as coloring agents for the keratin fibers is also provided.
Abstract:
The present disclosure relates to a novel family of dicationic bis-hydrazone compounds that may be used as direct dyes, and to a dye composition for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising, in a suitable dyeing medium, at least one such compound. Also disclosed are dyeing processes implementing this composition and uses thereof.
Abstract:
The present invention relates to a composition for dyeing keratin fibers, in particular human keratin fibers and more particularly the hair, which comprises at least one compound chosen from direct dyes of sulfonamidoxanthene type, in other words sulfonamide derivatives of xanthenes.The invention also relates to a process for dyeing keratin fibers, in particular human keratin fibers and more particularly the hair, using said composition.Finally, the invention relates to a multicompartment device comprising a compartment containing said dye composition.
Abstract:
A subject-matter of the present invention is the use, in the direct dyeing of keratinous fibres, of at least one direct dye and of a specific cationic hydrotropic agent of formula: in which X represents CH or N+R6 with R6 representing a C1-C10 alkyl, R1 represents either a hydrogen or a C1-C10 alkyl, if X represents N+R6, or (CH2)nN+R3R4R5 with R3, R4 and R5, which are identical or different, representing a C1-C10 alkyl and n representing an integer between 0 and 12, if X represents CH; R2 represents a C1-C4 alkyl; p has a value 0 or 1; the electrical neutrality of the compound being provided by a cosmetically acceptable anion or a mixture of cosmetically acceptable anions. The invention likewise relates to a dyeing composition comprising at least one dye and such a cationic hydrotrope and to colouring processes employing this dyeing composition.
Abstract:
A subject-matter of the present patent application is the use, as direct dye in dyeing compositions for keratinous fibres, in particular human keratinous fibres, such as the hair, or for the manufacture of such compositions, of a specific polycationic compound.
Abstract:
A composition for dyeing keratin fibers, such as human keratin fibers, and further such as the hair, comprising at least one dye chosen from heteroylmethane type direct dyes, such as triheteroylmethane direct dyes and leuco precursors of such dyes, as defined herein. A method that uses the composition for dyeing keratin fibers, such as human keratin fibers, and further such as the hair, and a kit or device containing same.
Abstract:
A composition for dyeing keratin fibers, for example, human keratin fibers, such as hair, comprising at least one dye chosen from heteroyldiarylmethane type direct dyes, for example, monoheteroyidiarylmethane direct dyes, and the leuco precursors thereof; and also to methods for dyeing keratin fibers, for example, human keratin fibers, such as hair, using the composition, and multi-compartment devices.
