Disclosed are detergent compositions containing polycarboxylate builders and one or more anionic, nonionic, or cationic detersive surfactants, or mixtures thereof, improved by the inclusion of certain polyhydroxy fatty acid amide surfactants. The compositions comprise at least 1 % by weight polycarboxylate builder, and at least 1 % by weight of a polyhydroxy fatty acid amide of formula (I) wherein R1 is H, C1-C4 hydrocarbyl, 2-hydroxy ethyl, 2-hydroxy-propyl, or a mixture thereof; and R2 is a C5-C31 hydrocarbyl; and Z is a polyhydroxyhydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyls directly connected to the chain, or an alkoxylated derivative (preferably ethoxylated or propoxylated) thereof.
L'invention porte sur des compositions détergentes renfermant des adjuvants à base de polycarboxylates, un ou plusieurs surfactifs détersifs anioniques, cationiques ou non ioniques, ou encore leurs mélanges, avec comme amélioration l'inclusion de certains surfactifs à base d'amides d'acides gras polyhydroxylés. Les compositions renferment au moins 1 % en poids de polycarboxylates et au moins 1 % en poids d'un amide d'acide gras polyhydroxylé de formule (I), où R1 est H, un radical hydrocarboné C1-C4, le 2-hydroxyéthyle, le 2-hydroxypropyle ou un mélange de ces groupes, R2 est un radical hydrocarboné C5-C31, Z est un radical hydrocarboné polyhydroxylé, comportant une chaîne hydrocarbonée linéaire avec au moins 3 hydroxyles directement liés à la chaîne, ou un dérivé alcoxylé (préférablement éthoxylé ou propoxylé) de ce radical.
