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.
浓缩物包含一种氨基化合物,该氨基化合物在氮原子上携带长链和中链取代基,而另外两个取代基要么是氢原子,甲基,乙基或β-羟乙基。中链取代基应具有长链取代基的一半碳原子或比一半少一到两个碳原子。除了水之外,浓缩物还可以包含相对于氨基化合物的总量,选自碱金属盐,铵盐,脂肪胺,具有6到20个碳原子的烷基或烯基酯或烯烃的一种或多种化合物,重量为0到10%。混合了几种氨基化合物的浓缩物也可以存在,其平均符合上述公式。浓缩物具有低粘度,使它们易于泵送,运输和计量。它们可以稀释而不会明显增加粘度,并且几乎不含易燃溶剂。
