Patent ID: 7332465

Claim:
A composition at least comprising one alkoxylate of the formula I: RO(A) n (B) m H (I) in which R is an alkyl radical of the formula C 5 H 11 CH(C 3 H 7 )CH 2 —, A is propyleneoxy, B is ethyleneoxy, n is an integer or fraction where 0<n<1, m is an integer or fraction where 2<m≦14, with the proviso that for R, isomer mixtures of an alkyl radical of the empirical formula C 5 H 11 CH(C 3 H 7 )CH 2 — comprising 70 to 99% by weight of a radical R1 in which C 5 H 11 has the meaning n-C 5 H 11 and 1 to 30% by weight of a radical R2 in which C 5 H 11 has the meaning C 2 H 5 CH(CH 3 )CH 2 and/or CH 3 CH(CH 3 )CH 2 CH 2 , are excluded, wherein the composition has a lower content of the residual alcohol than the residual alcohol content of the composition theoretically determined from a residual alcohol content of products containing only propylene oxide or only ethylene oxide, and wherein the content of zinc in the composition is greater than 0 and less than or equal to 15 ppm, or the content of cobalt is greater than 0 and less than or equal to 7 ppm, or the content of zinc is greater than 0 and less than or equal to 15 ppm and the content of cobalt is greater than 0 and less than or equal to 7 ppm.
