As the average degree of ethoxylation is included in the starting equation of the Weimer-Cooper's model, it was applied in an attempt to characterize the molecular mass distribution of an ethoxylated fatty alcohol. However, only a qualitative approximation of the distribution was possible with the Weimer-Cooper's constants. Consequently, the constants had to be calculated separately from measured mass distribution data. It was demonstrated that the two models predict the same constants when they are in modified form.
