- One step hair coloring compositions using salts
-
A hair coloring composition comprising the following two compositions which are mixed just prior to application to the hair: (a) a composition comprising a water-soluble peroxygen oxidizing agent; and (b) a composition comprising one or more oxidative hair coloring agents selected from the group consisting of an aromatic diamine, an amino phenol, a naphthol, a polyhydric phenol, a catechol and mixtures thereof; wherein the composition comprising one or more oxidative hair coloring agents further comprises al least one water soluble carbonate releasing salts; and optionally a water soluble ammonium salt, is described.

- Process for the two-stage oxidation dyeing of keratin fibers with a manganese complex or salt and a 4-substituted 1-naphthol, and dyeing kit
-
A process for the two-stage oxidation dyeing of keratin fibers by applying to the keratin fibers: in a first stage, at least one composition A containing at least one manganese salt and/or a manganese complex, in a second stage, at least one composition B having a pH of greater than or equal to 6, and resulting from the extemporaneous mixing of at least one composition B1 containing at least one 4-substituted 1-naphthol and at least one composition B2 containing at least one oxidizing agent, and corresponding multi-compartment dyeing kit.

- Dimeric Naphthoquinones, IV1). - Synthesis of Biramentaceone, Mamegakinone and Rotundiquinone
-
Mamegakinone (8a), biramentaceone (12a), 3,3'-bijuglone (8b), 2,2-bijuglone (12b) and their methyl ethers were prepared by oxidative coupling of substituted 4-methoxy-1-naphthols; indigoids like 24 are intermediates.Cooxidation of the isomeric dimethoxy-1
