<p>The present invention provides laundry detergent compositions comprising one or more water soluble anionic, cationic, ampholytic or zwitterionic detersive surfactants or mixtures thereof and a combination of (a) at least 1 % by weight of the composition of a polyhydroxy fatty acid amide having formula (I), wherein R1 is H, a C1-C4 hydrocarbyl, 2-hydroxy ethyl, 2 hydroxy propyl, or mixtures thereof, R2 is a C¿5?-C31 hydrocarbyl, and Z is a polyhydroxyhydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyl groups directly connected to the chain, or an alkoxylated derivative thereof; and (b) at least 1 % by weight of the composition of a substantially water-insoluble ethoxylated C11-C15 primary aliphatic alcohol containing an average of no more than five ethylene oxide groups per mole and having an ethylene oxide content of less than 50 % by weight. Preferred water soluble surfactants are anionic surfactants and more preferred compositions are free of alkyl benzene sulfonate surfactants.</p> |
