Disclosed are detergent compositions comprising alkyl sulfate and polyhydroxy fatty acid amide of formula (I) wherein R1 is H, C1-C4 hydrocarbyl, 2-hydroxy ethyl, 2-hydroxyl propyl, or mixture thereof, R2 is C5-C31 hydrocarbyl, and Z is a polyhydroxy hydrocarbyl with a linear hydrocarbyl chain having at least three hydroxys directly connected to the chain, or an alkoxylated derivative thereof, in combination with a suds suppressor. In another aspect, the alkyl sulfate and polyhydroxy fatty acid amide are utilized together within selected ratios for improved performance. In another aspect, liquid detergents are provided containing the polyhydroxy fatty acid amide and C14 or higher alkyl sulfates. In yet another aspect, detersive particles of alkyl sulfate and polyhydroxy fatty acid amide are provided. In yet another aspect, specified types of auxiliary surfactants are added to the composition for improved results.
n divulgue des compositions de détergent comportant un sulfate d'alkyle et un amide d'acide gras polyhydroxylique de formule (I), où R1 est un H ou un groupe hydrocarbyle en C1-C4 , 2-hydroxyéthyle, 2-hydroxy-1-propyle ou un mélange de ceux-ci, R2 est un groupe hydrocarbyle en C5-C31 et Z est un groupe hydrocarbyle polyhydroxylique à chaîne linéaire hydrocarbyle comportant au moins trois groupes hydroxyles directement sur la chaîne, ou un dérivé alkoxylé de ce groupe, combiné à un agent antimousse. Selon une autre variante, des particules détersives de sulfate d'alkyle et d'amide d'acide gras polyhydroxylique sont utilisées ensemble selon des rapports choisis pour un meilleur rendement. Selon une autre variante, on présente des détergents liquides contenant de l'amide d'acide gras polyhydroxylique et des sulfates d'alkyle en C14 ou plus longs. Selon une autre variante, on présente des particules détersives de sulfate d'alkyle et d'amide d'acide gras polyhydroxylique. Selon une autre variante, on ajoute à la composition des types particuliers de surfactants auxiliaires pour améliorer les résultats.
