Abstract

L'invention vise à améliorer le pouvoir lavant et rinçant, la fluidité et la pompabilité, ainsi que la stabilité au stockage et la résistance aux basses températures de détergents et de nettoyants et des intermédiaires utilisés pour les fabriquer. C'est possible du fait de la mise à disposition de mélanges tensioactifs qui contiennent dans des rapports en poids de 4:1 à 10:1 un alkyloligoalcoxylat à chaîne courte de la formule R1-(OC3H6)n-(OC2H4)p-OH, dans laquelle R1 désigne un reste alkyle ayant 6 à 10 atomes de C, n vaut un nombre compris entre 0,5 et 3 et p vaut un nombre compris entre 4 et 10, et un alkyloligoalcoxylat à chaîne longue de la formule R2-(OC2H4)q-OH, dans laquelle R2 désigne un reste alkyle ayant entre 12 et 22 atomes de C et q vaut un nombre compris entre 4 et 10.
