A process for reducing foam in an alkyl polyglycoside-containing cleaning composition by adding a defoaming-effective amount of an alkylpolyglycoside having the general formula (I): R1O(Z)a, wherein R1 is a monovalent organic radical having from 16 to 18 carbon atoms; Z is a glucose residue having 5 or 6 carbon atoms; a is a number having a value from 1 to about 6, to a cleaning composition containing an alkyl polyglycoside having the general formula (II): R2O(Z)a, wherein R2 is a monovalent organic radical having from 8 to 16 carbon atoms; Z is a glucose residue having 5 or 6 carbon atoms; a is a number having a value of from 1 to about 6.
La présente invention concerne un procédé servant à réduire la quantité de mousse dans une composition détersive contenant un polyglycoside d'alkyle, grâce à l'addition d'une quantité efficace, comme antimousse, d'un polyglycoside d'alkyle ayant de formule générale: R¿1?O(Z)¿a? (I), dans laquelle R¿1? est un radical organique monovalent ayant de 16 à 18 atomes de carbone, Z est un résidu de glucose ayant 5 ou 6 atomes de carbone, a est un nombre de 1 à environ 6; cela donne une composition détersive contenant un polyglycoside d'alkyle et ayant la formule générale R¿2?O(Z)¿a? (II), dans laquelle R¿2? est un radical organique monovalent ayant de 8 à 16 atomes de carbone, Z est un résidu de glucose ayant 5 ou 6 atomes de carbone et a est un nombre de 1 à environ 6.
