The pourability of a substantially non-aqueous liquid deter- gent upon storage at low temperatures may be ascertained by incorporating into it a liquid nonionic surfactant blend essentially consisting of: (a) a narrow range linear chain alkyl ethoxylated alcohol containing an average of from about 5 to 7 ethylene oxide groups per molecule; and (b) an ethoxylated alcohol containing an average of from about 2 to 3 ethylene oxide groups per molecule, the weight ratio between (a) and (b) being in the range of from 9:1 to 1:9, whereby the average chain length ranges from 9 to 14 carbon atoms and the melting point of said blend is lower than 5 °C, preferably lower than 0 °C. This type of non-aqueous liquid detergent is particularly suitable for use in industrial washing machines.
