Abstract: The invention provides compositions and methods containing novel bis-(2,4-diaminophenoxy)benzene coupling compounds, and cosmetically acceptable salts thereof, for use with conventional primary intermediate dye compounds and oxidizing agents for the oxidative coloring of human hair. The compositions of the invention may also contain other components typically used in oxidative hair dye preparations to impart intense and lasting coloration to hair.

Abstract: The oxidation hair dye composition is based on a combination of coupler substance and developer substance, and includes, as developer substance, at least one 2,5-diaminobenzonitrile compound of the formula (I), ##STR1## in which R.sup.1 and R.sup.2, independently of each other, are selected from the group consisting of H, alkyl groups having 1 to 6 carbon atoms, hydroxyalkyl groups having 2 to 4 carbon atoms and dihydroxyalkyl groups having 3 to 4 carbon atoms, with the proviso that both of the R.sup.1 and R.sup.2 groups are not both hydrogen at the same time, or a physiologically compatible water-soluble salt thereof. The invention also includes new 2,5-diaminobenzonitrile compounds of formula I.

Abstract: An oxidation dyeing composition for keratinous fibres, in particular human keratinous fibres such as hair, of the type comprising a medium suitable for dyeing, the medium containing at least one first para-phenylenediamine oxidation dye precursor containing a primary, secondary or tertiary amine function; at least one first meta-phenylenediamine coupling agent; and either at least one second para-aminophenol oxidation dye precursor or at least one second meta-aminophenol coupling agent; or the acid addition salts thereof. The use of this composition for dyeing keratinous fibres, in particular human keratinous fibres such as hair.

Abstract: The invention pertains to granules which incorporate citric acid monohydrate as an exotherm control agent within a peracid containing core. The granules have improved dissolution rates of the peracid in a dishwashing cycle. Compositions containing the granules are also described.

Abstract: A system for mixing and dispensing oxygen sensitive hair dye consists of concentrates in a sealed air-tight system using preferably 3--8 dye concentrates in collapsible bags having an oxygen barrier. The dye concentrates, along with oxygen activating liquids, are sufficient to produce an infinite number of hair dye formulations, thereby avoiding buying and stocking many bottles of specific color dyes. For formulating the dye mixtures, exact charges, i.e., volumes measured to within 1 ml, are raised from the bags and discharged. Each bag is removably connected, in an air-tight seal, to a separate precision lift pump whose piston lift excursion may be selectively set to determine the volume of the dye charge.

Abstract: The invention provides compositions and methods for the oxidative coloring of human hair. The compositions of the invention contain as a primary dye intermediate a 1-(4-aminophenyl) pyrrolidine, or a cosmetically acceptable salt thereof. The compositions may also contain at least one other primary intermediate and conventional coupling compounds, in addition to an oxidizing agent and other components typically used in oxidative hair dye preparations. Preferred dye intermediates in the compositions of the invention include 1-(4-aminophenyl) pyrrolidine and 1-(4-amino-3-methylphenyl) pyrrolidine, or cosmetically acceptable salts thereof, which produce intense neutral colors when used in admixture with a suitable coupling agents, such as 3-aminophenol, in conventional hair dye base formulations.
