Abstract

A process for protecting keratinous material with the aid of phenoxytrifluoromethanesulfonanilides, some of which are novel, from pests that feed on keratin, said phenoxytrifluoromethanesulfonanilides having the formula ##STR1## wherein R.sub.1 and R.sub.2, each independently of the other, are halogen, haloalkyl, alkyl, nitro, cyano, alkoxy or haloalkoxy, PA1 n is 0 or a value from 1 to 4 and PA1 m is 0 or a value from 1 to 3, with the proviso that if PA1 n or m>1, the substituents R.sub.1 and R.sub.2 may be identical or different, and that at least one substituent selected from the group consisting of halogen, haloalkyl and haloalkoxy is present in the molecule. The preparation of these compounds and the use thereof as active ingredients of compositions providing a mothproof and beetle-resistant finish are also described herein.
