Abstract
Abstract A mixture of zinc or copper salts of primary and/or secondary saturated acyclic carboxylic acids with zinc or copper salts of a tertiary saturated acyclic carboxylic acid has been found to be of value as a preservative for wood or many other similar degradable organic materials. The mixture can be prepared simply by mixing the salts or by reacting zinc or copper or a suitable zinc or copper compound with a mixture of the appropriate acids.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
79 words
A fungicidal composition comprising a mixture of: (a) a zinc salt of isononanoic acid and (b) a zinc salt of a mixture of tertiary saturated acyclic carboxylic acids which acids have the formula ##STR3## wherein R 3 , R 4 and R 5 represent an alkyl group which together contain about 8 carbon atoms, the weight ratio of zinc salt of isononanoic to zinc salt of a said mixture of tertiary saturated acyclic carboxylic acids being 75:25 to 25:75.
