A process for reducing foam in an alkyl polyglycoside-containing cleaning composition by adding a defoaming-effective amount of an alkoxylated alcohol having the general formula (I): R1(EO)x(PO)y-OH, wherein R1 is derived from a linear or branched alkyl chain having from about 8 to about 14 carbon atoms; x is a number having a value of from 1 to about 10; y is a number having a value of from 1 to about 10, to a composition containing an alkyl polyglycoside having the general formula (II): R3O(R4O)b(Z)a, wherein R3 is a monovalent organic radical having from about 6 to about 30 carbon atoms; R4 is divalent alkylene radical having from 2 to 4 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; b is a number having a value from 0 to about 12; a is a number having a value from 1 to about 6. |
