ABSTRACT:
A method for preserving wood which comprises contacting the wood with a complex of a cationic monomeric or polymeric biocide and an anionic monomeric or polymeric biocide. Insoluble complexes may solubilized in water in the form of an emulsion or microemulsion by adding a nonionic and/or amphoteric surfactant and/or aqueous cosolvent to the complex. Suitable cationic biocides are those that contain functionalities such as amidine, guanidine, biguanide, quaternary, phosphonium, sulfonium and gemini quaternary functionalities. Suitable anionic biocides include: phenolics; saturated, unsaturated or substituted carboxylates; organomercaptide; tetrathiocarbonates; cyanodithioimidocarbamates; dithiodialkylcarbamates; anionic oxides of transition metals; aminocarboxylic acids; aminoorganophosphonic acids; monoalkyl phosphates; dialkylphosphates; and substituted or unsubstituted 2-hydroxy-2,4,6-cycloheptatrianone.
