A quaternary ammonium salt of the formula: SPC1 EQU1 wherein A is a lower alkylene, a lower alkenylene or a lower alkadienylene; R1 and R2 are each lower alkyl which may be linked together directly or by an oxygen atom to form a saturated heterocyclic group; R3 is a lower alkyl, a halo (lower) alkyl, a lower alkynyl, phenyl (lower) alkyl which may have one or more halogen atoms as substituents on the phenyl ring, a lower alkenyl, a hydroxy (lower) alkyl, a carboxy (lower) alkyl or a lower alkenyloxycarbonyl (lower) alkyl; R4, R5 and R6 are each lower alkyl having 1 to 3 carbon atoms; X is an acid residue; and wherein the cyclohexyl ring may have one double bond, with the proviso that when the cyclohexyl ring has one double bond in the 1,2 position, A may not be EQU2 when X- is iodide, R4, R5 and R6 are all methyl; R1, R2 and R3 are all methyl or all ethyl, or R1 is methyl, R2 is ethyl and R3 is phenylisopropyl or isoamyl with the further proviso that when the double bond in the cyclohexyl ring is in the 2,3 position, A may not be EQU3 when X- is iodide, and R1, R2, R3, R4, R5 and R6 are all methyl.
