Abstract
A microemulsion is prepared containing: a mixture of (1) nitrogenous compounds, (2) from 10-5% by weight of an alkyl or alkenyl phosphoric ester surfactant, the alkyl and alkenyl groups of which contain less than 12 carbon atoms per group and the ester surfactant containing from 1 to 10 alkoxy radicals, (3) from 3 to 20% by weight of at least one cosurfactant, (4) a vegetable oil, an animal oil or a fatty acid and (5) a plasticizer. The microemulsion having a viscosity at 5.degree. C. less than or equal to 200 mPa.multidot.sec and is stable at a temperature of -10.degree. C. to +50.degree. C. Further, the microemulsion is useful as a biodegradation accelerator.
