摘要： The present invention relates to a defoamer oil compound that contains an organopolysiloxane (A), a fine silica powder (B), and a group (C) that is represented by the organopolysiloxanes of formulas (I) and/or (II) (in the formulas, c, d, and e are each an integer of 0 or more, and at least one of X1 to X3 is the group represented by formula (i)). The component (C) is used as a surface treatment agent for the component (B). The present invention makes it possible to obtain a silicone-based defoamer composition that imparts good initial defoaming properties even in an alkaline foaming liquid, that exhibits very little loss in performance over time, and that has excellent defoaming performance.
