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.
