Compositions and method for coloring keratin fibers consisting of derivatives of benzo[b]furan-3-one and/or benzo-[b]-thiophen-3-one compounds with special reactive components. These compositions form intensely colored compounds when applied to keratin fibers. The compositions may also be used with substantive dyes and/or oxidation colorants.

Hair dyeing agents containing indigo derivatives

A coloring composition and a method of coloring keratin-containing fibers are provided. The coloring composition contains a mixture of and/or a reaction product of at least one aromatic aldehyde or ketone and at least one CH-active compound. In the method of the present invention, the aromatic aldehyde or ketone and the CH-active compound may be applied to keratin-containing fibers simultaneously or successively.

Agent for coloring keratin containing fibers

Agent for dying keratin fibers

A coloring composition and a method of coloring keratin-containing fibers are provided. The coloring composition contains a mixture of and/or a reaction product of at least one heteroaromatic aldehyde or ketone and at least one aromatic and/or heteroaromatic nitroamine. In the method of the present invention, the heteroaromatic aldehyde or ketone and the nitroamine may be applied to keratin-containing fibers simultaneously or successively.

Dyeing agent for keratinous fibers

Utilization of onium aldehydes and onium ketones for dying fibers containing keratin

A colorant composition for coloring keratin-containing fibers is disclosed having (a) at least one isatin derivative corresponding to the formula I:

Use of 1-substituted isatins to dye fibers containing keratin

In machine dishwashing using low-alkaline detergents, the protection of silver was to be guaranteed. This was achieved by using 3-amino-5-alkyl-1,2,4-triazoles and salts thereof as silver protectors in machine dishwashing detergents. In addition, the dishwashing detergents may contain bleaching agents and builders.

Isatin derivatives for coloring keratin-containing fibers

The invention relates to the use of acylated sugar monoacid amides in cosmetic preparations corresponding to formula I: ##STR1##

Sugar monoacid amides in cosmetic preparations

Isatin-containing formulations for coloring keratin-containing fibers

Novel alkyl aryl ether derivatives corresponding to the formula: ##STR1## in which R.sup.1 is a C.sub.8 -C.sub.20 alkyl group with one or more branches, E is a group --CH.sub.2 --CH.sub.2 -- or --CH.dbd.CH-- and R.sup.2 is a C.sub.1 -C.sub.4 alkyl group, a C.sub.2 -C.sub.4 hydroxyalkyl group, an alkoxyalkyl group containing 1 to 4 C atoms in the alkoxy group and 2 to 4 C atoms in the alkyl group, hydrogen or a salt-forming cation, are highly effective sebosuppressive agents in cosmetic or pharmaceutical preparations for topical application to the hair and to the skin.

Novel sebosuppressive compounds and preparations

Alkyl and alkenyl aryl ether derivatives corresponding to the formula: ##STR1## in which R.sup.1 is a saturated cycloaliphatic C.sub.6 -C.sub.20 alkyl group or a mono- or polyunsaturated, linear, branched or cycloaliphatic C.sub.6 -C.sub.20 alkyl group and R.sup.2 is a C.sub.1 -C.sub.4 hydroxyalkyl group, a C.sub.3 or C.sub.4 hydroxyalkenyl group, a group --COOR.sup.3, --CH.sub.2 --COOR.sup.3, --CH.sub.2 --CH.sub.2 --COOR.sup.3 or --CH.dbd.CH--COOR.sup.3, are suitable as sebosuppressive agents in cosmetic or pharmaceutical preparations for topical application to the hair and to the skin.

Sebosuppressive topical preparations

3-acylamino-1,2,4-triazoles corresponding to the following general formula ##STR1## and 1-acyl-3-amino-1,2,4-triazole corresponding to the general formula ##STR2## in which R is a linear or branched C.sub.1-11 alkyl or phenyl, and mixtures thereof are used as corrosion inhibitors for non-ferrous metals in aqueous systems, oils and oil-containing emulsions.

Acylated 3-amino-1,2,4-triazoles as corrosion inhibitors for non-ferrous

Sebosuppressive compositions comprising a cosmetically- and pharmaceutically-acceptable carrier and an antiseborrheic agent consisting essentially of a 4-alkoxy- or 4-(4-alkylbenzyloxy)-benzoic acid and a purine compound corresponding to the formula: ##STR1## or the purine 1,3,7,9-tetramethyluric acid; or a physiologically-acceptable salt thereof. The antiseborrheic action of the 4-alkoxy- or 4-(4-alkylbenzyloxy)-benzoic acids is potentiated by the purine compounds. Preferred purine compounds are theophylline, theobromine and caffeine.

Sebosuppressive compositions and method for suppressing sebaceous gland

Oxidation hair-dyeing preparations which contain as couplers N-(2-4dihydroxbenzylidene)-amino compounds corresponding to the following formula ##STR1## in which A is a group corresponding to one of the following formulae ##STR2## or salts thereof and the developers normally present in oxidation hair dyes. p-Phenylenediamine and derivatives thereof are particularly suitable as developers. Yellow to olive-brown colors of high fastness are obtained.
