    摘要： There are provided wax solutions self-dispersible in waterborne wood preservatives containing hexavalent chromium to form stable emulsions. There is also provided a method of preserving wood wherein wood is impregnated with said emulsions. The solutions comprise a hydrocarbon solvent having dissolved therein from 5 to 25 percent by weight of a hydrophobic wax and at least 4 percent by weight of a non-ionic surface active agent having an HLB value between 7 and 11, the surface active agent being a condensate of a long chain fatty alcohol or an alkyl phenol with ethylene oxide.
