Carrier composition for oxidative dyeing of hair and method of dyeing

The creamy bleaching agent suspension is mixed with an oxidizing agent prior to applying it to the hair to form a composition for bleaching or decolorizing hair. This creamy bleaching agent suspension contains less than 2.5% by weight water and a mixture of at least one inorganic persalt, at least one alkaline reacting salt, from 0.5 to 20 percent by weight of a thickening substance, which consists essentially of an acrylic acid polymer and one or more cellulose, alginate and/or polysaccharide polymers, and from 26.5 to 35 percent by weight of at least one oil or wax, and, as needed, one or more cosmetic additive ingredient. From 0.1 to 3 percent by weight of the acrylic acid polymer must be present in the composition.

Composition for bleaching hair

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.
