Aqueous unbuilt liquid or gel-form detergent compositions are provided comprising, from 15 % to 65 % by weight of a core surfactant mixture, comprising from 5 % to 95 % by weight of the mixture of a water soluble anionic sulphate or sulphonate surfactant salt together and from 5 % to 95 % by weight of the mixture of one or more compounds of formula (I), wherein Z is a polyhydroxy hydrocarbyl moiety having a linear hydrocarbyl chain with at least three hydroxy groups connected directly to the chain, said moiety being derived from glucose and mixtures thereof with maltose, the maltose comprising not more than 33 % of the mixture, R is a C6-C16 hydrocarbyl radical and R1 is a C1-C4 alkyl or C2-C4 hydroxyalkyl group, a 0.12 % solution of the surfactant mixtures of the compositions having an interfacial tension (IFT) of less than 0.2 Pa.cm at 48 °C and a polypropylene cup (PPC) greasy soil removal value of at least 1.4 x that of the anionic surfactant component(s) alone. Preferred optional ingredients include amide, betaine and ethoxylated C9-C11 fatty alcohol suds modifiers. |
