Abstract
There are provided compositions for the preservation of wood and related cellulosic and lignocellulosic materials. The wood preservative compositions of the present invention contain an organic preservative agent and an organic acid, and can be solubilized in an organic phase essentially free of volatile organic compounds (VOC). The organic acids may serve various purposes in the compositions of the present invention: (1) increased preservative solubility in the organic phase, (2) improved distribution gradient of the active preservative in treated wood, or (3) reduction of preservative leaching.
