A method of making cellular polyurethane material comprises reacting an organic polyisocyanate with an essentially hydroxyl terminated polyester and/or polyether polyol in the presence of 10 % - 100 % by weight (based on the polyol) of an alkanolamine salt of polymerized fatty acids (monomer 0-80 wt.%; dimer 10-100 wt.%; trimer 0-75 wt.%) and an inert (preferably halogen-free), stable, vaporizable blowing agent. Also a cellular polyurethane material is claimed and the use of the alkanolamine salt as a multifunctional additive in the manufacture of cellular polyurethane material.
