Zusammenfassung:PURPOSE:To enable to obtain an aqueous mold release agent having performance which is not inferior to a solvent series mold release agent, by making the softening point and the melting viscosity of nonvolatile content fall within a specific range, in an emulsion obtained by emulsifying wax by making use of an emulsifying agent by loading a small quantity of an organic solvent to the wax. CONSTITUTION:The title agent is an emulsion to be obtained by emulsifying a mixture of wax obtained by loading a 5-20wt part organic solvent to the 1,000wt part wax containing more than 70wt part polyethylene wax whose acid value is less than 1 by an emulsifying agent having volatile amine salt or ammonium salt of aliphatic acid having 12-20 pieces of carbon atoms for its indispensable ingredient and aliphatic acid ester of multivalent alcohol for its optional ingredient and is a composite of aqueous mold release agent for molding soft polyurethane foam made of the composite whose softening point of nonvolatile content is 50-100 deg.C and melting point is 20-100CP at the temperature of 120 deg.C. When wax content in the wax other than the polyethylene wax exceeds 30wt%, mold release characteristics are deteriorated.
