[과제] 저가격의 글리콜 에테르 화합물을 원료로서 사용한 경우에도, 충분한 품질 및 정포성을 가지며, 또한, 거품 증강 성능이 우수한 조성물/정포제를 제공하는 것. [해결 수단] 특정 폴리에테르-폴리실록산 블록 공중합체 (A')와 특정 글리콜 에테르 화합물 (B')를 질량비로 (A'):(B')=20~60:80~40(여기서, (A')(B')의 총량을 100으로 한다)의 범위로 함유하는 조성물이며, 또한, (K) 특정 1가 칼륨염을 칼륨 원자 환산으로 3~300 wt.ppm의 범위로 함유하는 조성물 및 그의 제조방법. Provided is a composition or foam stabilizer which has sufficient quality and foam stability even when an inexpensive glycol ether compound is used as a raw material, and that has excellent foam-enhancing performance. The composition contains a specific polyether-polysiloxane block copolymer (A′) and a specific glycol ether compound (B′) at a mass ratio of (A′):(B′)=(20 to 60):(80 to 40) (wherein the total amount of (A′) and (B′) is 100. The composition further contains (K) a specific monovalent potassium salt in the range of 3 to 300 wt. ppm calculated as potassium atoms. A method for manufacturing the composition is also provided.
