Abstract: The object of the present application is a dye carrier composition containing oxidative and/or non-oxidative dyes as well as (a) 6.1 to 25 weight percent of at least one fatty alcohol with 14 to 20 carbon atoms, (b) 1 to 20 weight percent of at least one fatty acid alkanolamide and (c) 1 to 15 weight percent of at least one fatty alcohol alkoxylate and/or fatty acid alkoxylate, the weight ratio of fatty alcohol (a) to fatty acid alkanolamide (b) being equal to 4:1 to 1:3 and at the same time the weight ratio of fatty alcohol (a) to alkoxylate (c) being equal to 5:1 to 1:2. Another object is the use of the afore-said combination of components (a) to (c) to produce a nacreous luster effect in dye carrier compositions and colorants for keratin fibers.

Abstract: The colorant for dyeing keratin fibers contains oxidation dye precursors and/or direct dyes and a combination of from 2 to 12 percent by weight of at least one long-chain fatty alcohol, from 2 to 12 percent by weight of at least one alkanolamide, from 0.5 to 10 percent by weight of at least one fatty alcohol alkoxylate and from 0.5 to 10 percent by weight of at least one quatemary ammonium compound. The weight ratio of fatty alcohol to alkanolamide is from 0.5:1.5 to 1.5:0.5. A method of making the colorant is described.

Abstract: A new oxidizing agent composition for mixing with oxidation dye pre-cursor compounds, such as developer and coupler substances, to form a ready-to-use dye mixture for dyeing keratin fibers is described. The oxidizing agent composition contains from 0.01 to 25 percent by weight of at least one alkaline earth peroxide, based on the ready-to-use dye mixture, and from 0.01 to 25 percent by weight of at least one inorganic or organic acid, salt of the at least one organic or inorganic acid or mixture of the salt and/or the at least one acid, based on the ready-to-use dye mixture.

Abstract: The new bis-pyrazole aza compounds have the formula (I): ##STR1## wherein R.sub.1, R.sub.1 ', R.sub.2, R.sub.2 ', R.sub.3 and R.sub.3 ' are the same or different, and are each, independently of each other, H, a straight, branched or cyclic alkyl group having 1 to 6 carbon atoms, a straight chain or branched monohydroxyalkyl group or polyhydroxyalkyl group with 1 to 6 carbon atoms, a straight or branched alkoxyalkyl group with 2 to 6 carbon atoms, a straight or branched monoaminoalkyl group or polyaminoalkyl group with 2 to 6 carbon atoms, or an unsubstituted aromatic or heteroaromatic ring, or a substituted aromatic or heteroaromatic ring having one or more halogen, a C.sub.1 - to C.sub.4 -alkyl group, a nitro group, a sulfonic acid group, a carboxylic acid group or a C.sub.1 - to C.sub.4 -alkoxy substituent, or an unsubstituted benzyl group, or a benzyl group substituted with one or more halogen atom, a hydroxy group, a C.sub.1 - to C.sub.4 - alkyl group, a nitro group or a C.sub.1 - to C.sub.
