Abstract

The present invention relates to compositions at least comprising one alkoxylate of the formula RO(A)n(B)mH, to processes for the preparation of such compositions, in particular in the presence of double-metal cyanide compounds as catalyst, and their use as emulsifier, foam regulator or as wetting agents for hard surfaces. Moreover, the present invention also relates to the use of such compositions in detergents and surfactant formulations.
