Abstract: A multicomponent product container includes two separate component compartments covered by a common pouring cap, individual pouring openings for the first and second components contained in the compartments, respectively, offset from one another relative to the longitudinal axis of the container and opening in the plane of an outer surface provided in said cap. The pouring openings are each juxtaposed in the pouring direction necessary to dispense the first and second components, by an individual pouring edge, which both rises beyond the outer surface of the cap, and projects beyond the associated pouring opening in the lateral or peripheral direction. Each pouring edge is shaped for providing in the tilted position of the container necessary for pouring via gravity said first and second components from said pouring openings, a sink formed in the region of the associated pouring opening.

Abstract: Novel compounds with structures corresponding to the formula: ##STR1## in which n=0 or 1 and R.sup.1 is hydrogen, a C.sub.1 -C.sub.4 alkyl or hydroxyalkyl group, or an amino group, and salts of such compounds, are superior to previously known couplers for oxidation hair dyes to produce a variety of colors, especially reds, when used with standard developer components. With 2,4,5,6-tetraaminopyrimidine developer for example, these novel compounds produce red to brown hair colors and, with p-tolylenediamine developer, red to blue-violet hair colors.

The process comprises applying to the coloring bath a controllable, asymmetrical and substantially sinusoidal a.c. voltage of substantially constant frequency. The sinusoidal a.c. voltage is obtained from a voltage source supplying a symmetrical sinusoidal a.c. voltage and at least one of the two current paths is divided into two parallel main lines and fed to electrical components whereby the amplitude level of the positive half wave and the amplitude level of the negative half wave and the ratio of the amplitude level of the positive half wave to the amplitude level of the negative half wave of the a.c.

Abstract: In light colored surfactants produced by sulfonation of fatty acid alkyl esters with less than 2 moles of SO.sub.3 per mole of fatty acid alkyl ester and subsequent work-up of the crude sulfonate in aqueous medium to form salts, the content of .alpha.-sulfofatty acid disalts is regulated and reduced by transesterifying the sulfonation product before its treatment with an aqueous medium with at least about 0.5 mole equivalent of an alcohol, based on the SO.sub.3 which is not for .alpha.-sulfonation.

The product collected in the sump of the column is removed, heated and returned to the lower part of the reaction column. Product is removed from the sump. Lower alkanols passing from the reaction column section to the rectifying section are rectified. The reaction column is operated in boiling equilibrium in its lower part and predominantly in an absorption/desorption equilibrium in its upper part.
