Abstract
A wood preservative composition for treating wood to impart biocide and antimicrobial characteristics to wood contains a mixture of one or more cleaning members containing quaternary salts, an aromatic quaternary salt, a copper sulfate, a glycol ether and a chelator, mixed with water. The preferred active members are tetradecyltrimethylammonium bromide, tetrasodium ethylenediaminetetraacetic acid, benzethonium hydrochloride, copper sulfate pentahydrate and 2-butoxyethanol. The chelator is tetrasodium salt ethylenediamine of tetraacetic acid (EDTA).
