ABSTRACT:
This invention relates to new and improved chlorinated phenol water soluble wood treating compositions and methods for preservation of wood or products made from wood. In the general practice of this invention, wooden objects are treated with water soluble wood treating and preserving solutions consisting of blends of from 0.1% to about 50% by weight of a chlorophenol selected from a group consisting of pentachlorophenol and tetrachlorophenol and mixtures thereof, from about 1% to about 97% by weight aliphatic alcohols having from 1 to 6 carbon atoms and mixtures thereof, from about 0.2% to about 35% of a fatty acid amine oxide or a mixture of fatty acid amine oxides and other amines, and from about 1% to about 97% by weight water. In addition, these wood treating formulations may contain up to 10% by weight of added ingredients selected from the group of tetrasodium pyrophosphate, copper salts, sodium chromates, sodium gluconate, sodium citrate, sodium N-dihydroxyethylglycinate and/or up to 20% by weight ammonium or sodium lignin sulfonate.
In practice of this invention, these compositions are incorporated into treating systems that adequately penetrate wood and deposit essentially non-leachable chlorophenols in the wooden objects.
