A process for the use of .omega.-Aminocarboxylic acid amides of the formula ##STR1## wherein R is an aliphatic hydrocarbon residue having 10 to 14 carbon atoms, R.sub.1 and R.sub.2 are selected from the group consisting of hydrogen, methyl, --CH.sub.2 --CH.sub.2 OH, --CH.sub.2 --CHOH--CH.sub.3 and --CH.sub.2 --CHOH--CH.sub.2 OH, and m and n are integers from 1 to 10, to prevent the growth of microorganisms including compositions of phosphonate sequestering agents and .omega.-aminocarboxylic acid amides for use in industrial water treatment.

Antimicrobial use of .omega.-aminocarboxylic acid amides

An aqueous hair dye preparation comprising an oxidation dyestuff combination of a coupling component and a developer component consisting of a tetraaminopyrimidine derivative or a water-soluble acid addition salt thereof, as well as a process for dyeing hair by utilizing this oxidation dyestuff combination.

Oxidation hair dyes based upon tetraaminopyrimidine developers

Anti-inflammatory cyclic 2-furfural-acetals of the formula ##SPC1## In which X is hydrogen, a lower alkyl preferably having 1 to 4 carbon atoms, or nitro, Z is an alkylene of the formula

Anti-inflammatory composition and method containing cyclic

A process for producing an addition product of an epoxy compound with a reaction product of .epsilon.-caprolactam and an N-alkylalkylene diamine, as well as the addition product produced by the process. The process of using these addition products is to prevent the growth of microorganisms in industrial water, by incorporating into said industrial water an antimicrobially effective amount of said addition product, and optionally incorporating into said industrial water a sequestering agent comprising a water-soluble phosphonic acid which forms a complex with a divalent metal, a water-soluble salt of the acid and the mixtures thereof, with the weight ratio of sequestering agent to addition product being 1:10 to 10:1.

Adducts of epoxy compounds and products of reaction of

A hair dye preparation contains diamino-nitrobenzene compounds as a direct hair dye or contains diamino-nitrobenzene compounds as coupling components in combination with developing components for oxidation dyestuffs. A process for dyeing human hair comprises applying one of these preparations to the hair.
