Aquathol K, a formulation of dipotassium endothall, is not mutagenic in fruit flies, mold, or human white blood cells. No information is currently available. Inorganic salts of endothall in aquatic formulations are safe to fish in 100-500 ppm concentrations. Endothall is highly mobile in soil, however rapid degradation limits the extent of leaching. No information is currently available.
All properties are for technical endothall unless otherwise noted.
Technical endothall is a colorless or white crystal which is stable to light, weak acidic media and weak alkaline media.
