Beschreibung
Zusammenfassung:	The present invention pertains to an antifoam composition which is for a hydraulic composition and contains an anionic surfactant (A) and an antifoaming agent (B), wherein the anionic group of (A) is: an unneutralized compound; or a compound of an amine salt, an ammonium salt, or an alkali metal salt. L'invention concerne une composition d'agent antimousse pour composition hydraulique qui comprend (A) un agent tensio-actif anionique et (B) un agent dans lequel un groupe anionique est un sel d'amine, un sel d'ammonium ou un sel de métal alcalin. 本発明は、（Ａ）アニオン性界面活性剤と、（Ｂ）消泡剤とを含有する水硬性組成物用消泡剤組成物であって、前記（Ａ）が、アニオン基が未中和の化合物、又はアニオン基がアミン塩、アンモニウム塩もしくはアルカリ金属塩の化合物である、水硬性組成物用消泡剤組成物である。
