The family of AE are composed of compounds that differ in chain length with respect
to the number of carbon units and the number of ethylene oxide units. The physicochemical
properties of AE therefore span a broad range. Although very little specific
information is available concerning several of the physicochemical properties of
specific AE homologues, an extensive data set is available for the alcohols (the EO=0
homologues). In many cases it is possible to use the alcohol information to set upper
or lower limits for the specific physicochemical property for the other AE
homologues, and thus evaluate their chemical and physical chemical behaviour.
