FULLY WATER-DILUTABLE MICROEMULSIONS Abstract of the Disclosure The present invention provides a composition suitable for use as a fungicide, slimicide, algicide and/or bactericide in many areas of preservation and agricultural applications. The aforesaid composition comprises (A) one or more active ingredient compounds which are less than 1000 ppm soluble in water at room temperature and having a melting point of less than 100°C; (B) one or more non-polar, water immiscible solvents selected from the group consisting of benzyl alcohol, benzyl acetate, pine oil, phenethyl alcohol, xylenel phenoxyethanol, butyl phthalate, 2,2,4-trimethyl-1,3-peneanediol monoisobutyrate, and alkylbenzene, said solvent being capable of dissolving at least 5 % by weight of (A) at room temperature; (C) a surfactant system comprised of: (C1) one or more sulfated or sulfonated anionic surfactants having about 3- 17% sulfation or sulfonation, selected from the group consisting of sulfated and/or sulfonated castor oil, sulfated and/or sulfonated ethoxylated alkylphenols, sulfated and/or sulfonated ethoxylated fatty alcohols, sulfated and/or sulfonated fatty acids, and sulfated alkanolamides; and (C2) one or more ethoxylated surfactants selected from the group consisting of ethoxylated (C10-C18)alkyl phosphate monoesters and/or diesters and/or triesters, ethoxylated (C10-C-18)alkaryl phosphate monoesters and/or diesters, ethoxylated alkanols, and ethoxylated castor oil; and (D) 0 to 99% by weight water; the weight ratio of (C1) to (C2) being about 10/90 to 90/10; the weight ratio of said (A) to (B) being about 95/5 to about 1/99; and the weight ratio of said (A) to (C) being about 1/99 to about 86/14; said composition being thermodynamically stable and clear, opalescent, or only slightly cloudy at all levels of water dilution up to 99.9%.
