Abstract:
An anhydrous miniemulsion concentrate which forms a stable oil in water emulsion upon dilution, comprising, by weight,(a) between about 0.05 and about 25% of at least one active aza compound selected from the group consisting of Amitraz and an aza compound having the formula:R.sub.1 --(X)--R.sub.2wherein one of R.sub.1 and R.sub.2 is alkenylphenyl, aminophenyl or a sulfur- and/or nitrogen-containing heterocyclic radical containing 3 to 5 carbon atoms in a 4 to 6 membered ring and the other of R.sub.1 and R.sub.2 is the same or is selected from the group consisting of amidosulfuron, phenyl, sulfonylphenyl, phenyloxy and phenyloxysulfonyl where said phenyl radicals and said heterocyclic radicals are optionally substituted with lower alkyl, halo, haloalkyl, cyano, C.sub.1 to C.sub.4 alkyl ether, C.sub.1 to C.sub.4 ester, carboxyl, ketone amido and amino and X is: ##STR6##where R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are each individually selected from the group consisting of hydrogen, lower alkyl, cyano, and amino,(b) between about 2 and about 40% of a lipophilic lactam selected from the group consisting of C.sub.8 to C.sub.18 N-alkyl pyrrolidone, C.sub.8 to C.sub.18 alkyl caprolactam and a mixture thereof,(c) between about 2 and about 20% of a moisture scavenging agent selected from the group consisting of a hindered carbopolyimide, a molecular sieve and a mixture thereof, and(d) between about 10 and about 80% of a lipophilic/hydrophilic mixture having an overall HLB of 7 to 20, comprising at least two emulsifiers wherein at least two of said emulsifiers in the mixture are non-ionic.
