Abstract

Abstract The invention relates to an odoriferous formulation containing an odoriferous compound of between 3 and 60 carbon atoms and having an acidic hydrogen atom and a quaternized fragrance extender having the formula ##STR1## wherein X - is an anion; m is an integer having a value of from 1 to 4; R is linear alkylene having from 3 to 8 carbon atoms and is optionally substituted with C 1 to C 4 alkyl; R 1 , R 2 and R 3 are each independently selected from the group of alkyl, alkyleneoxyalkyl, alkoxy, alkyleneoxyalkenyl, alkylhydroxy, aryl, aralkenyl, aralkyl, alkaryl, alkyleneamidoalkyl, alkylenecarbamoyalkyl, arylenecarbamoylalkyl and aryleneamidoalkyl radicals, said groups each having up to 30 carbon atoms and at least one of R 1 , R 2 and R 3 is a radical having from 8 to 30 carbon atoms, except that alternatively R 2 and R 3 with the quaternized nitrogen can form a 5 to 14 membered heterocyclic ring having from 1 to 2 heteroatoms selected from the group of oxygen, nitrogen and sulfur, in which case R 1 can be any of the aforementioned groups or can represent a bond in an unsaturated quaternized heterocyclic ring.
