Abstract
The present invention is directed to a method of detoxifying water containing quaternary ammonium compounds to the extent that aquatic life such as fish and macroinvertebrates are protected. The method comprises adding to an aqueous system including a quaternary ammonium compound a sufficient quantity of a de-oiled lecithin. De-oiled lecithin is a mixture of phosphatides with about 2% or less residual oil.
