Abstract

PURPOSE: To obtain a new type of self-emulsifying type defoaming agent composed mainly of an organopolysiloxane, having excellent foam-suppressing and breaking capability regardless of the temperature and pH of a liquid to be treated and also of the storage period.
CONSTITUTION: The defoaming agent contains as the main component an oxyalkylene group-containing organopolysiloxane of the formula [where R1 is H or a 1W2C monovalent hydrocarbon, G is oxyalkylene group, Y is -CH2-(CH-R4)- R5-D, or -CH2-(CH-R6)-CO-OR7(R4, R6, and R7 are each H or an alkyl group, R5 is a divalent hydrocarbon, and A is H or OH), (a), (b), and (c) are each 0. 1, 2, or 3(but a+b+c=3), (m) and (n) are each an integer of 1 or above and l is 0 or a positive integer of 20 or below].
