Abstract
A wood preservative effective against blue stain containing a fatty acid of 6-11 carbon atoms, boric acid and an alkali compound in stoichiometric excess of the fatty acid. The resulting composition is readily soluble in water, and the resulting solution can be applied by spraying onto the wood or be used as a bath into which wood is dipped.
