Abstract:
1. A method of protecting wood through enhanced penetration of wood preservatives into the wood comprising: providing a solution containing at least one amine oxide, at least one wood preservative, and a non-borate dual buffering agent, said solution having a pH of about 5 to 12.4, applying said solution to the wood surface, and activating said solution to effect penetration of said wood preservative into said wood, employing said buffering agent in a weight percent of at least 3 percent of said solution weight, effecting by said method interaction of said amine oxide with said non-borate dual buffering agent to create a synergistic effect to effect penetration with said wood preservatives into said wood to a greater depth than would exist without said buffering agent, and selecting said buffering agent from the group consisting of (a) a mixture of a weak acid with its conjugate base and (b) a mixture of a weak base and its conjugate acid and said buffering agent contains no substantial amount of borates, boric acid, or borax, whereby the interaction of the amine oxide with the non-borate dual buffering agent will have a synergistic effect and cause said greater depth of penetration of said wood preservative into said wood.
