Abstract
The invention relates to an emulsifiable microemulsion concentrate containing a phophoric acid ester and/or thiophosphoric acid ester as active ingredient. In addition to 20 to 80% by weight of active ingredient, the composition comprises: 7 to 70% by weight of a nonionic surface active agent, preferably a block copolymer with a molecular weight of 1000 to 10000 formed from polyethylene oxide and polypropylene oxide, an alkylphenol polyglycol ether, ethoxylated fatty alcohol or a mixture of nonionic surface active agents; 2 to 50% by weight of water; if desired, 1 to 50% by weight of a co-surfactant, preferably C.sub.1-8 straight or branched chain and/or cyclic alcohol, C.sub.3-8 straight or branched chain and/or cyclic ketone, esters of C.sub.1-6 fatty acids with C.sub.1-6 alcohols or the mixture thereof; and if desired, 15 to 30% by weight of a water-immiscible organic solvent.
