The present invention provides a storage stable isocyanate-reactive component useful in the production of polyurethane foams and elastomers. Fatty alcohol ethoxylates having a ≧ 10 wt% vegetable oil-based polyol based on the weight of the isocyanate-reactive component, a polymerized ethylene oxide content of ≧ 25 moles per equivalent of alcohol or phenol, and an HLB value of> 17 And a nonionic emulsifier containing one of aliphatic phenol ethoxylates, a non-vegetable oil-based polyol, and a silicone surfactant, and is storage stable at a temperature of -10 ° C to 60 ° C for at least 3 days Providing an isocyanate-reactive component; The isocyanate-reactive components of the present invention can be transported and stored at normal shipping and storage temperatures and are routinely acceptable to help meet the “more environmentally friendly” requirements of polyurethane foam and elastomer producers The right foam.
