Abstract

The concentrate contains an ammonium compound which carries a longer-chain and a medium-chain substituent on the nitrogen atom, and both the other substituents are either hydrogen atoms, methyl, ethyl or .beta.-hydroxyethyl. The medium-chain substituent should have half the carbon atoms of the longer-chain substituent or one or two carbon atoms less than half. Instead of an ammonium compound, a mixture of several ammonium compounds can also be present which on average corresponds to the formula described above. In addition to water, the concentrate can also contain 0 to 10% by weight, relative to the total amount of the ammonium compounds, of one or more compounds which are selected from amongst alkali metal salts, ammonium salts, aliphatic amines, alkyl or alkenyl esters or olefins having 6 to 20 carbon atoms. The concentrates have a low viscosity, which makes them easily pumpable, transportable and meterable. They can be diluted without noticeable increase in viscosity and contain virtually no combustible solvents.
