Abstract

A wood preservative composition comprising a biocide such as a quaternary ammonium compound, e.g., didecyldimethyl ammonium chloride (DDAC), an isothiazolone or an isophthalonitrile, in combination with an antioxidant, which is a flavone or a phenol, is useful as a cost-effective and environmentally safe wood preservative. The invention also provides a method for the use of such composition and compositions so treated.
