  • Patent number: 5554197
    Abstract: The present invention relates to methods and systems for hair dying. The system includes at least two reservoirs containing different hair dying components in predetermined concentrations, the containers including outlets having cross-sectional areas which are sized relative to the concentration of the component contained in the reservoir and the amount of that component needed to react with the remaining components. The measuring device calibrated with respect to the concentrations of the hair dye components and the cross-sectional areas of their respective reservoir outlets, permits rapid and accurate dispensing of the hair dye components in the proper quantities. In a preferred arrangement, the measuring device is provided on a blending board so that the components can be blended together immediately upon dispensing.

  • Patent number: 5542953
    Abstract: The composition for the oxidative dyeing of hair contains at least one coupler of the general formula ##STR1## where R is a straight-chain or branched C.sub.1 - to C.sub.4 -alkyl group, X is chlorine or fluorine, and R.sup.1 is a straight-chain or branched C.sub.1 - to C.sub.4 -alkyl group or a straight-chain or branched C.sub.2 - to C.sub.4 -hydroxyalkyl group. The 5-halogen-2,4-bis(alkylamino)-1-alkylbenzenes of the formula (I) are novel. The couplers of the general formula (I) may be obtained through simple chemical reactions, are easily soluble in water and have an outstanding shelf stability, in particular as a constituent of the hair dye composition described here. The dyeing results which can be achieved with the hair dye composition according to the invention are particularly distinguished by the color intensity of the red hues, in addition to the multitude of shades, and by a good purity of color with respect to blue hues.
