Abstract:
In a method for controlling the foaming of a waterborne composition or an industrial process by the incorporation of a foam controlling agent, the improvement which comprises adding as the foam controlling agent a compound of the formula:wheren and m are 2 or 3, x is 1 or 2, andRâ€² is a C4 to C22 alkyl group, the compound, when added at 0.1 wt % to a 0.1 wt % aqueous solution of dioctyl sodium sulfosuccinate (DOSS). generating an initial foam height of such aqueous solution that is at least 30% less than the initial foam height of the aqueous DOSS solution without such compound, the compound added to the waterborne composition or industrial process at 0.01 to 10 g/100 mL.
