Abstract
The present invention provides a polyol composition that can secure the stability over time even when a large amount of water is blended in the polyol composition; a flexible polyurethane foam that uses the polyol composition, is low in density and is excellent in durability; and a method for producing the same. The above objects are solved by a polyol composition for molding a flexible polyurethane foam, comprising a polyol component; a catalyst; a foam stabilizer; a foaming agent; and a compatibilizing agent, wherein the compatibilizing agent is an anionic surfactant which has a hydrophilic portion having an alkali metal salt, and which has a hydrophobic portion having an aromatic ring or alternatively a hydrophobic portion not having an aromatic ring but containing 8 or more carbon atoms in total.
