Abstract
The polarity indexes of surface-active ethylene oxide adducts with varying lipophilic parts and varying content of ethylene oxide have been studied. An interesting relationship has been found between the fraction of ether groups and polarity index, which gives a polarity index line for every type of ethylene oxide adduct. It permits the calculation of polarity indexes of all ethylene oxide adducts of known composition with known polarity index of the lipophilic part. It also gives valuable information for evaluating different lipophilic substances as raw materials for ethylene oxide adducts.
