摘要:
The invention relates to dyeing compositions for direct dyeing of keratinic fibres, containing, in a cosmetically acceptable medium:(a) at least one yellow or green-yellow dye corresponding to the formula (I): ##STR1## in which X=Cl, Br, F, and R.sub.1 and R.sub.2 denote, independently of each other, hydrogen, alkyl, hydroxyalkyl, or alkylaminoalkyl in which the aminoalkyl group may be mono- or disubstituted provided that R.sub.1 and R.sub.2 do not simultaneously denote a hydrogen atom, and(b) at least one blue or violet dye corresponding to the formula: ##STR2## in which R.sub.3 denotes a hydrogen atom or an alkyl, monohydroxyalkyl, polyhydroxyalkyl or alkoxyalkyl radical and R.sub.4 and R.sub.5 have separately the same meanings as R.sub.3 but cannot denote a hydrogen atom.
摘要:
Use for dyeing keratinous fibres, and especially human hair, on a compound corresponding to the formula: ##STR1## in which X denotes a bromine or chlorine atom.
摘要:
The invention provides a composition and process for directly dyeing keratinic fibres. The combination of 1-N-methylamino-2-nitro-4-N'-methyl-N'-(2' ,3'-dihydroxypropyl)amino benzene with certain 2-nitroparaphenylenediamine direct nitro dyes produces a dye composition in which the dyes can be more concentrated (without crystallizing out) and hence produce darker shades.
摘要:
Dyeing compositions are disclosed which comprise at least one oxidation dyestuff precursor in combination with at least one direct dyestuff, in an aqueous vehicle, the direct dyestuff being a nitro derivative of the benzene series having the formula: ##STR1## in which R.sub.1 denotes the methyl group, R.sub.2 and R.sub.4 denote hydrogen and R.sub.3 denotes the .beta.-hydroxyethoxy group, or alternatively R.sub.1, R.sub.3 and R.sub.4 denote hydrogen and R.sub.2 denotes the methyl or hydroxyl group, or alternatively R.sub.1 and R.sub.2 denote hydrogen, R.sub.3 denotes the methyl group and R.sub.4 denotes the hydroxyl, (.beta.-hydroxyethyl)-amino or (.beta.-N,N-diethylaminoethyl)-amino group, or R.sub.1, R.sub.2 and R.sub.3 denote hydrogen and R.sub.4 denotes the N,N-bis-(.beta.-hydroxyethyl)-amino group.
摘要:
The invention provides new chlorine-substituted nitro-para-phenylenediamines of the formula: ##STR1## in which R.sub.1 and R.sub.2, which are identical or different, denote hydrogen, a lower alkyl group or a monohydroxylated or polyhydroxylated alkyl group and n is an integer from 2 to 4, and the cosmetically acceptable salts of these compounds. These compounds can be used for hair dyeing.
摘要:
The present disclosure relates to an agent for dyeing and/or bleaching keratin fibers, comprising: composition (A) comprising at least one basifying agent, and anhydrous composition (B) comprising hydrogen peroxide and/or at least one hydrogen peroxide precursor, wherein composition (A) and/or composition (B) comprise at least one fatty substance not containing any carboxylic acid functional groups, such that the total amount of the at least one fatty substance not containing any carboxylic acid functional groups is present in the mixture of composition (A) and composition (B) in an amount greater than 20% by weight. The disclosure also relates to a process for treating human keratin fibers using this dyeing and/or bleaching agent, and a multi-compartment kit comprising this dyeing and/or bleaching agent in at least two parts.
摘要:
