ABSTRACT OF THE INVENTION Tertiary amine catalyst mixtures comprising at least one hydroxyalkyl piperazine, preferably 2-hydroxyethyl piperazine or 1,4-di-(2-hydroxyethyl) piperazine, and at least one other tertiary amine for increasing the processability of hydroxyalkyl piperazine in controlling the water-isocyanate reaction rate to obtain optimum performance in cellular polyurethane foam formulations and/or enhancing the compatibility of hydroxyalkyl piperazine with other foaming ingredients in flexible polyester polyurethane foam formulation; and a process for producing cellular polyurethanes, such as flexible polyester or polyether polyurethane foam and high resilience polyether polyurethane foam, by effecting the reaction of an organic polyol reactant and an organic polyisocyanate reactant in the presence of a blowing agent and said tertiary amine catalyst mixture, the resulting cellular polyurethanes exhibiting very low residual amin? odor.
