The invention relates to the use of a composition comprising at least one compound of the general formula (I) (see formula I) where R1 are identical or different, straight-chain or branched, aliphatic or aromatic, optionally halo-genated, optionally unsaturated hydrocarbon radicals having 1 to 8 carbon atoms, k = 0 to 10, R2 is a group of the formula A-B-D-Q, where A is an oxygen atom, a CH2 group or a CH=CH group, B is a CH2 group or a divalent radical selected from linear or branched, saturated, mono- or polyunsaturated alkyloxy, aryloxy, alkylaryloxy or arylalkyloxy groups having 2 to 20 carbon atoms or a group of the formula -CH2-O-(CH2)4-O-, D is a group of the general formula (II) -(C2H4O)n(C3H6O)o(C12H24O)p(C8H8O)q(C4H8O)r- (II) where n, o, p, q and r are mutually independent integers from 0 to 50, where the sum of the indices n + o + p + q + r is greater than or equal to 3 and the general formula II represents a statistical oligomer or a block oligomer, and Q is a radical selected from hydrogen, linear or branched, saturated, mono- or polyunsaturated alkyl, aryl, alkylaryl or arylalkyl groups having 1 to 20 carbon atoms, optionally containing one or more heteroatoms, optionally containing one or more carbonyl groups, optionally modified with an ionic organic group,in the production of polyester polyurethane foams, and to a process for producing such compositions.
