摘要：
Disclosed is a method for controlling foam formation in an aqueous system containing at least one biocidal quaternary ammonium and/or phosphonium compound, wherein the at least one quaternary ammonium and/or phosphonium compound is selected from (i) a compound having the formula [QR1R2R3R4]*X- (l), wherein the substituents are as disclosed in the specification (ii) a compound having the formula R19R20R21R22Q+X- (II), wherein the substituents are as disclosed in the description (iii) a polymeric quaternary ammonium or phosphonium biocide and (iv) a mixture of two or more quaternary compounds of any of (i) to (iii), said method comprising the addition of at least one anionic diester surfactant in a molar ratio of anionic surfactant to quaternary ammonium and/or phosphonium compound of 0.001 to 0.09, to said aqueous system. Also disclosed is the method of killing or inhibiting the growth of microorganisms, algae or fungi by applying the formulation above.
