Phenalkoxyalky- and phenoxyalkyl-substituted oxiranecarboxylic acids of the formula ##STR1## wherein R.sup.1 denotes a hydrogen atom (--H), a halogen atom, a lower alkyl group, a lower alkoxy group, a nitro group or a trifluoromethyl group, R.sup.2 has one of the meanings of R.sup.1, R.sup.3 denotes a hydrogen atom (--H) or a lower alkyl group, Y denotes --O--(CH.sub.2).sub.m --, m denotes O or an integer from 1 to 4, and n denotes an integer from 2 to 8, with the proviso that the sum of m and n is an integer from 2 to 8, and the salts of the acids are new compounds. They display a hypoglycaemic action in warm-blooded animals. Processes for the preparation of the new compounds and of the intermediate products required for their preparation are described.
