<p>A polyol composition for reacting with a polyisocyanate to form a polyurethane resin, comprises: (a) a triglyceride of a C12 to C25 hydroxy-substituted fatty acid or a C12 to C25 hydroxy-substituted fatty acid and glycerol, which can react together to produce a triglyceride; and (b) at least 0.1 mole, per mole of triglyceride (a) or triglyceride capable of being formed from the fatty acid and the glycerol, of an oxide, hydroxide or carbonate of a metal from Group IIA of the periodic table.
