Abstract
Biocidal preservatives for use especially in preventing rotting and deterioration of wood include quaternary ammonium compounds which preferably have a fatty aliphatic substituent on the quaternary nitrogen atom. Especially preferred are cocoalkyl substituents. Other substituents can include alkoxy groups, arenes, and heterocyclic groups with or without ring substitutions, for example. The quaternary ammonium compound can also contain an amine nitrogen and can be complexed with copper.
