The present invention provides an isocyanate-reactive component containing at least 10 wt.%, based on the weight of the isocyanate-reactive component, of a vegetable oil-based polyol, a nonionic emulsifier containing one of an aliphatic alcohol ethoxylate and an aliphatic phenol ethoxylate having a polymerized ethylene oxide content of at least 25 moles per equivalent of alcohol or phenol and a HLB value greater than 17, one or more non-vegetable oil-based polyols, one or more silicone surfactants, and optionally, water or other blowing agents, catalysts, pigments and fillers, wherein the isocyanate-reactive component is storage stable at temperatures of from -10°C to 60°C for at least three days. The inventive isocyanate-reactive component can be shipped and stored at normal shipping and storage temperatures and still produce acceptable foam on a daily basis whilst helping to satisfy polyurethane foam and elastomer producers "green" requirements.
