    • Composition (A) comprising: a) at least one compound of formula (I): (Z)y—(G)x—O—RA  (I); b) at least one compound of formula (II): Z—O—[CH2—CH(R1)—O]n—RB  (II); c) optionally one or more compounds of formula (IV): (G)x—O—RA  (III), and d) optionally one or more compounds of formula (IV) HO—[CH2—CH(R1)—O]n—RB  (IV), wherein the weight ratios of (I) to (II) is 0.1 to 10, (III)/(I) is 0 to 1, and (IV)/(II) is 0 to 1, and in each formula: Z is a —CH(CH3)—O—R2 group, wherein R2 is an aliphatic hydrocarbon radical of 1 to 30 carbons, y is greater than 0 and less than or equal to 3x+1; x is 1 to 5; n is 1 to 30; R1 is a hydrogen or methyl; G is the residue of a saccharide; RA and RB are independently a hydrocarbon radical of 1 to 30 carbons. Composition (A) has application as an antifoam in cleaning compositions.
