ABSTRACT:
The tendency to opacify of a polyol composition comprising one or more zinc fatty acid salts such as zinc stearate, added to form a mold release agent when the polyol is converted to a molded polyurethane article, is retarded by the presence of a small but effective amount of one or more fatty alkyl diethoxylate (e.g. diethanolamine) compounds.
