The incorporation of a poly(siloxane-glycol) surfactant having a cloud point ranging from 25-50°C into a water-based mold release composition comprising an aqueous emulsion or dispersion of at least one release effective substance and desirably at least one emulsifying agent provides for improved surface quality of the foam product. Also disclosed is a method for preparing a polyurethane foam article in a mold by applying to a mold surface a water-based mold release composition which comprises a release effective system which is in a solid (hardened) state at the mold pour temperature and a liquid state at the demold temperature, pouring a polyurethane foam composition into the mold, curing the foam composition and demolding the foam article. The use of such release effective system in the aqueous mold release composition provides for a reduction in surface defects of the polyurethane foam article.
