Abstract: 1532506 Emulsion concentrates of waterinsoluble biocides HOECHST AG 29 Jan 1976 [31 Jan 1975] 03511/76 Heading A5E An emulsion concentrate of a water-insoluble organic biocide which is sensitive to hydrolysis in an organic non-polar solvent which is free from hydroxyl groups, contains an anionic emulsifier and optionally an ionic emulsifier, and has as viscosity reducing agent a compound of formula: in which each of R 1 and R 2 is an alkyl group having from 1 to 4 carbon atoms, an alkylcarbonyl group having from 2 to 4 carbon atoms or a carbamoyl group having from 1 to 4 carbon atoms, X is an alkylene group having from 2 to 4 carbon atoms and n is in the range of from 1 to 20. The biocide may be a phosphoric or thiophosphoric acid ester and the solvent may be benzene, toluene, xylene or kerosine. Viscosity reducing agents used are ethylene glycol dimethyl and diethyl ethers; di-, tri- and tetra-ethylene glycol dimethyl ethers; diethylene glycol dibutyl ether; methyl-tetraglycol t-butyl ether; methyl glycolbutyl glycol-, and methyldiglycol-acetates; glycol diacetate; ethyl glycol- and methyldiglycolmethylurethanes; propanediol- and butanedioldiacetates; and butanediol dimethylurethane.
