    Abstract: The invention relates to a defoamer composition. The invention also relates to a method for reducing or preventing foam in an aqueous composition. The defoamer composition of the invention comprises at least one hydrophobic liquid; and at least one modified polyacrylate polymer. The modified polyacrylate polymer is obtainable by a process comprising 1. polymerizing at least one acrylate monomer selected from substituted or unsubstituted C1-C22 alkyl acrylates, substituted or unsubstituted C4-C22 cycloalkyl acrylates, substituted or unsubstituted C1-C22 acrylamides, esters of acrylic acid with polyalkylether alcohol, or combinations of two or more thereof, to obtain at least one polyacrylate polymer; and 2. modifying the at least one polyacrylate polymer obtained in step (i) by transesterification with at least one alcohol selected from (c1) at least one unsubstituted C8-C36 alcohol, (c2) at least one polyalkylether alcohol, or combinations of two or more thereof.
