<p>Disclosed is an antisapstain composition comprising a haloalkynyl compound, an azole and an unsaturated carboxylic acid, alkali metal salt or alkaline earth metal salt thereof. A specific example of a haloalkynyl compound is 3-iodo-2-propynyl butyl carbamate (IPBC). Specific examples of an unsaturated carboxylic acid are sorbic acid, sodium sorbate, potassium sorbate, myristoleic acid, palmitoleic acid, oleic acid, elaidic acid, linoleic acid, alinolenic acid, arachidonic acid, eicosapentaenoic acid, euric acid, docosahexanoic acid, fumaric acid, maleic acid and maleic anhydride. Specific examples of the azole include substituted imidazoles and 1,2,4-triazoles. The antisapstain compositions are useful for treating wood and other cellulosic materials and protecting substrates against moulds, staining and other defacing organisms.</p> |
