摘要:
The invention relates to a dyeing composition for keratinous fibres containing at least one 4-bis(.beta.-hydroxyethyl)amino-2-nitro-1-(N-substituted amino)benzene compound in which the substitution is C.sub.1 -C.sub.3 alkyl or .beta.-hydroxyethyl; this composition contains as co-solubilization agent at least one dye of formula (II) ##STR1## in which formula: R.sub.2 denotes a C.sub.2 -C.sub.3 hydroxyalkyl group;R.sub.3 denotes a C.sub.2 -C.sub.3 hydroxyalkyl group; with the proviso that, if R.sub.3 =CH.sub.2 CH.sub.2 OH, R.sub.2 is necessarily an .alpha.-hydroxyethyl or hydroxypropyl radical.
摘要:
The invention relates to a dyeing composition for keratinous fibres containing, in a suitable vehicle, at least one nitrated direct dye of the 2-nitro-paraphenylenediamine series, in which the amino group in position 4 is mono- or disubstituted with lower alkyl or hydroxyalkyl radicals and in which the amino group in position 1 is optionally monosubstituted with a lower alkyl or hydroxyalkyl radial, and the aromatic ring can be substituted or unsubstituted on the remaining positions; the invention consists in introducing into such a composition an imidazolidinedione or one of its substitution derivatives, to improve the solubility of the abovementioned nitrated direct dye by a co-solubilization phenomenon. The invention also relates to a process for dyeing keratinous fibres using such compositions.

Use of hydroxyanthraquinones for the coloration of human keratin fibres, and process and composition in which they are used.The composition contains, in a cosmetically acceptable medium, at least one hydroxyanthraquinone of the formula: ##STR1## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 independently of one another denote a hydrogen atom, a hydroxyl group, an alkyl group, an alkyl group substituted, for example, by a hydroxyl, amino or acyl group, an alkoxy group, a nitro group, a halogen group, a group SO.sub.3 H, CHO, CO.sub.2 H or SO.sub.3 Na, or a group --CO.sub.2 R', in which R' denotes alkyl or an alkali metal, with the proviso that: at least two of the groups R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 denote hydroxyl, and that if R.sub.1 and R.sub.2 denote OH, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 denoting hydrogen, then at least one of the two groups R.sub.3 and R.sub.4 is different from hydrogen, or alternatively if R.sub.1 and R.sub.3 denote OH, R.sub.2 and R.sub.4 denoting hydrogen and one or two of the substituents R.sub.5, R.sub.6, R.sub.7 and R.sub.8 denoting hydroxyl, then at least one of the substituents R.sub.5, R.sub.6, R.sub.7 and R.sub.8 is different from hydrogen, alkyl or halogen.
摘要:
The invention discloses the use of hydroxyl derivatives of benzaldehyde for coloring keratin fibres without an oxidizing agent. These derivatives are of the type which correspond to the formula: ##STR1## in which R denotes a linear or branched lower alkyl group which is optionally substituted by one or two OH groups, n is equal to 1, 2 or 3, m is equal to 0, 1 or 2 and the sum n+m is equal to 2 or 3.
摘要:
The invention relates to compositions for hair dyeing which contain, as the oxidative dye-stuff, in a cosmetically acceptable medium, para-phenylenediamine and ortho-aminophenol, or their cosmetically acceptable salts, in a ratio para-phenylenediamine/ortho-aminophenol which is such that, after the addition of an equal volume of hydrogen peroxide of 20 volumes strength and application to the hair for 30 minutes, no Bandrowsky's base can be detected in the oxidizing dyeing composition.The compositions according to the invention make it possible to impart background colorations to the hair without the formation of Bandrowsky's base.
