The present invention relates to a process for producing integral polyurethane foams, in which a) organic polyisocyanates are mixed with b) relatively high molecular weight compounds having at least two reactive hydrogen atoms, c) blowing agents, d) dialkyl cyclohexanedicarboxylates and, if appropriate, e) chain extenders and/or crosslinkers, f) catalysts and g) other auxiliaries and/or additives to form a reaction mixture, the reaction mixture is introduced into a mold and allowed to react to form an integral polyurethane foam. The present invention further relates to integral polyurethane foams comprising dialkyl cyclohexanedicarboxylates, the use of such foams in the interior of road vehicles or as shoe soles and the use of dialkyl cyclohexanedicarboxylates as internal mold release agents in the production of integral polyurethane foams.
