APPLICANTS HAVE DISCOVERED THAT AMINE OXIDES ENHANCE THE UNIFORM DISTRIBUTION AND PENETRATION OF WOOD PRESERVATIVES INTO WOOD SUBSTRATES, MINIMIZE LEACHING OF THE WOOD PRESERVATIVES, AND IMPROVE THE WEATHERABILITY OF THE WOOD SUBSTRATE. THE PRESENT INVENTION PROVIDES A METHOD FOR ENHANCING THE UNIFORM DISTRIBUTION AND PENETRATION OF AT LEAST ONE WOOD PRESERVATIVE INTO A WOOD SUBSTRATE BY APPLYING A PRESERVATIVE COMPOSITION TO THE WOOD SUBSTRATE. THE PRESERVATIVE COMPOSITION COMPRISES A WOOD DISTRIBUTION AND PENETRATION ENHANCING AGENT, WHICH INCLUDES AN AMINE OXIDE, AND THE WOOD PRESERVATIVES. ANOTHER EMBODIMENT OF THE PRESENT INVENTION IS A METHOD FOR ENHANCING THE UNIFORM DISTRIBUTION AND PENETRATION OF ONE OR MORE WOOD PRESERVATIVES BY APPLYING THE WOOD PRESERVATIVES TO THE WOOD SUBSTRATE AND THEN APPLYING THE AFOREMENTIONED WOOD DISTRIBUTION AND PENETRATION ENHANCING AGENT TO THE WOOD SUBSTRATE. ALTERNATIVELY, THE WOOD DISTRIBUTION AND PENETRATION ENHANCING AGENT MAY BE APPLIED PRIOR TO APPLICATION OF THE WOOD PRESERVATIVES OR BOTH MAY BE APPLIED CONCURRENTLY. YET ANOTHER EMBODIMENT IS A PRESERVATIVE COMPOSITION COMPRISING A WOOD DISTRIBUTION AND PENETRATION ENHANCING AGENT AND AT LEAST ONE WOOD PRESERVATIVE. PREFERABLY, THE COMPOSITION COMPRISES A UNIFORM DISTRIBUTION AND PENETRATION ENHANCING EFFECTIVE AMOUNT OF THE WOOD DISTRIBUTION AND PENETRATION ENHANCING AGENT AND A WOOD PRESERVING EFFECTIVE AMOUNT OF THE WOOD PRESERVATIVE.
