Patent ID: 8252719

Claim:
A microemulsifiable concentrate (MEC) of a hydrophobic agrochemical, said concentrate comprising in % by weight: (a) at least one hydrophobic agrochemical in an amount of about 0.1 to about 25% of the MEC; (b) a solvent system comprising: (i) a first solvent which is selected from the group consisting of C 6 -C 13 alkyl C 1-4 alkanoates in an amount of about 10 to about 35% of the MEC; and (ii) a second solvent which is selected from the group consisting of polydric alcohols, condensates of polyhydric alcohols, and mixtures thereof in an amount of about 10 to about 45% of the MEC; and (c) at least one surfactant in an amount of about 1 to about 40% of the MEC, wherein the at least one surfactant includes at least one of (c)(i) at least one cationic surfactant selected from the group consisting of polyC 2-4 alkoxylated fatty amines and (c)(ii) at least one nonionic surfactant selected from the group consisting of mono C2-6alkyl ether of a polyC2-4alkylene oxide block copolymer having at least a first polyalkylene oxide block region and a second polyalkylene oxide block region in which the polyalkylene oxide in said first region is different than the polyalkylene oxide in said second region, a condensation product of castor oil and a polyC2-4alkylene oxide, a mono- or di-ester of a C12-24fatty acid.
