<p>A concentrated liquid detergent composition which can be liquid at or below ambient temperature comprises (i) at least 40 wt % and less than 92 wt % of a mixture of surfactants, at least 50 wt % of the surfactants present comprising: (a) a polyalkoxy nonionic surfactant conforming to the general formula RVEW 10 wherein R is an aliphatic and/or araliphatic hydrocarbon moiety, V is a linking group, E is a polyethoxy and/or polypropoxy and W is a nonionic end group, the nonionic surfactant for the portion RE having a hydrophile-lipophile balance of at least 14.5 where E is polyethoxy and an equivalent hydrophile-lipophile balance where E is propoxy, and (b) an ionic surfactant having a non-terminal ionic head group with two or more hydrocarbon chains extending from the head group, each chain being no more than 10 carbon atoms in length and the chains having a total length of at least 8 carbon atoms; wherein the ratio of (a) to (b) lies within the range of from 1:9 to 9:1, and (ii) at most 60 wt % and more than 8 wt % water.</p> |
