ABSTRACT:
This invention relates to a compound, composition or formulation, and/or a method of preparing a compound or formulation, having biocidal properties against certain microbiological or macrobiological organisms, or both, for example, against certain fungi, insects and molluscs, and which is intended particularly though not necessarily solely for use in the preservation of timber.
It is therefore an object of the present invention to provide a biocidal and/or preservative compound, composition or formulation, and/or a method of preparing a biocidal and/or preservative compound, composition or formulation, which will at least provide the public with a useful choice.
Accordingly, in one aspect the invention consists in a method of preparing a compound or formulation having biocidal or preservative properties, or both, said method comprising the steps of:
reacting an organic complexing agent with a borate or boric acid to produce a borate organic complex ion.
Preferably, said method includes the further step of reacting said complex ion with a suitable cationic species.
Preferably said organic complexing agent is an organic alcohol.
Preferably said organic complexing agent is selected from the group consisting of 1,2 diols, 1,3 diols, 1,3,5 triols and polyhydroxy macrolide-type compounds.
More preferably said organic complexing agent is selected from the group consisting of naphthalene diols, phenyl glycols, glycerol ethers, dihydroxy phenyl compounds, dihydroxy anthracene compounds, methylol phenols, methylol naphthols, methylol anthrols, aliphatic 1,2 diols, aliphatic, 1,3 diols, and triol monoesters.
Preferably said cationic species is selected from the group consisting of ions of copper, zinc, hydrogen, barium, sodium, potassium, magnesium, calcium, iron, manganese, cobalt and nickel, and suitable cationic organic species, including alkyl (C
9
-C
16
) dimethyl amines, dialkyl (C
7
-C
14
) methyl amines, alkyl (C
9
-C
16
) dimethyl benzyl ammonium, dialkyl (C

) dimethyl ammonium and substituted triazole compounds e.g. 1-[[2-(2,4-dichlorophenyl)-1,3-dioxolan-2-yl]methyl]-1N-1,2,4-triazole.
In a further aspect the invention consists in a compound, composition, or formulation having biocidal or preservative properties, or both, comprising the product of the method set forth in any of the preceding paragraphs.
In a still further aspect the invention consists in a compound, composition or formulation having biocidal or preservative properties, or both, comprising a borate organic complex ion.
Preferably said compound, composition, or formulation further contains a biocidally active cationic species.
To those skilled in the art to which the invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the scope of the invention as defined in the appended claims. The disclosures and the descriptions herein are purely illustrative and are not intended to be in any sense limiting.
