摘要:
The invention relates to hair-dyeing compositions based on para-phenylenediamine. These compositions contain, as the oxidation dyestuff, para-phenylenediamine and one or more para-phenylenediamines of the formula ##STR1## in which R denotes alkyl or hydroxyalkyl and R' denotes a hydroxyalkyl group, and also their cosmetically acceptable salts, in a molar ratio para-phenylenediamine/compound(s) of the formula (I), expressed in terms of free bases, 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 is detected in the oxidizing dyeing composition.These compositions make it possible to obtain natural background colorations, ranging from black to light chestnut, of very good quality.
摘要:
The invention relates to compositions intended for dyeing keratin fibers which contain, as the only oxidative dyestuffs, oxidative dyestuff precursors of the para type and of the ortho type, at least one said precursor of the para type being an aromatic diamine, or specified formula or a specified bis-condensed precursor and at least one said precursor of the ortho type which is an ortho-aminophenol, ortho-diphenol, ortho-phenylenediamine or a derivative thereof.
摘要:
A compound of the formula A-NR--(CH.sub.2).sub.n --NHR' wherein R and R' are hydrogen, n is a whole number between 2 and 6 inclusive and A is selected from (1) anthraquinonyl per se wherein NR-(CH.sub.2).sub.n --NHR' is in position 2 or (2) anthraquinonyl of the formula ##STR1## wherein R.sub.1 and R.sub.2 are selected from hydrogen and lower alkyl, and the NR--(CH.sub.2).sub.n --NHR' chain is in position 5. The compound is useful as a basic dye in coloring the hair.
摘要:
2,5-diamino-1,4-benzoquinones are used in the production of hair dye compositions and can be prepared by condensing a corresponding 3-amino-4-methoxy phenol derivative on one of a corresponding hydroxy aniline or phenylenediamine derivative, a corresponding benzoquinone imine derivative or a corresponding nitroso derivative.
摘要:
Compositions for dyeing keratin fibres are provided based on a novel para-phenylenediamine oxidative dye which has the formula: ##STR1## in which R represents hydrogen, chlorine or methyl or a salt thereof.
