| A resin composition includes a polyol and is used to form flexible foams. The resin composition also includes water and an alkoxylate of an active hydrogen containing species. The alkoxylate of the active hydrogen containing species acts in two separate ways. The alkoxylate acts as a blowing reaction modifier, thus maintaining slow-blow behavior of a foaming process that accompanies a reaction of the polyol with an isocyanate. The alkoxylate also acts as a compatibilizer. As the compatibilizer, the alkoxylate stabilizes the resin composition such that no phase separation occurs between the polyol, the water, and the alkoxylate. Stabilizing the resin composition allows for multiple day storage of the resin composition with no phase separation, thus extending useable shelf life and reducing production costs. Stabilizing the resin composition also allows for formation of flexible foams with consistent physical properties such as flexibility. | ||||||
