Abstract

PURPOSE: To provide an antifoaming agent which is cheap and water-soluble, by using a prescribed glycolic compound having alkylene oxide addition structure, as the effective constituent of the antifoaming agent.
CONSTITUTION: Alkylene oxide such as ethylene oxide is added to a branched- chain glycol represented by formula I, without a catalyst, or in the presence of a base or an acid catalyst. The product with addition structure is used as the effective constituent of an agent for eliminating bubbles produced in paper-making industry, fermentation industry or the like. In the formula, R1 denotes an alkly group and R2 and R3 denote hydrogen or an alkyl group and are not the same. This results in enabling the simple, easy and economic manufacturing of the antifoaming agent whose effective constituent is water-soluble.
