Abstract Branched-chain aliphatic carboxylic acids, or their alkali- or ammonium salts, are used for the protection of wood and other cellulose-based materials against attacks of sapstain and mould fungi. The acids contain 6 to 20 car- bon atoms and are iso-acids or acids which are mono-branch- ed in 2-position. 2-ethyl hexanoic acid, or its salts, is particularly preferred. The acids are particularly suitab- le for short-term protection treatment of wood. The acids can be applied in the form of water solutions or dispersions by means of dipping, coating or brushing.
