Methods for reducing aldehyde emissions in polyurethane foams

A method for producing a polyurethane foam comprising forming a reaction mixture that contains an aromatic polyisocyanate, at least one isocyanate- reactive material having an average functionality of at least 2 and an equivalent weight of at least 200 per isocyanate-reactive group, at least one blowing agent, at least one surfactant and at least one catalyst, and curing the reaction mixture in the presence of (i) 0.02 to 0.15 parts by weight per 100 parts by weight of the at least one isocyanate-reactive material of at least one acetoacetate ester or amide selected from the group consisting of trimethylolpropane triacetoacetate ester, trimethylolethane triacetoacetate ester, and

• an amide compound having the structure (ii) 0.05 to 0.25 parts by weight per 100 parts by weight of the at least one isocyanate-reactive material of at least one aminoalcohol and/or alkylhydroxylamine selected from the group consisting of 1,1,1-tris (hydroxymethyl) methylamine and ethanolamine, and (iii) 0.1 to 1.5 parts by weight per 100 parts by weight of the at least one isocyanat-reactive material of a phenolic antioxidant to form the polyurethane foam.
