Microbicidal system, and processes to stabilize a microbicidal composition against the formation of precipitate brown and conrolar or inhibit the growth of microorganisms in a locality

摘要

Microbicidal composition, and,Processes for stabilizing a microbicidal composition against the formation of precipitate brown and to control or inhibit the growth of microorganisms in a locality is presented a case In order to stabilize diluted solutions of compounds of 3 - isotiazolona against the formation of precipitate undesirable brown in the presence of low levels of copper.By the addition of 2 to 50% of an organic solvent soluble in water.Preferably, aqueous solutions are substantially free of metal nitrate, nitrite and metal stabilizers of magnesium salts.
