"Methylisothiazolinone is used to control slime-forming bacteria, fungi, algae in pulp/paper mills, cooling water systems, oil field operations, industrial process waters, and air washer systems and is incorporated into fuels, coatings, adhesives, metal working fluids,emulsions, paints, and various other specialty industrial products as a preservative. It is also used to control the growth of mold, mildew, and sap-stain on wood products. Formulations include concentrated liquids and soluble concentrated solids. In studies using laboratory animals, methylisothiazolinone has been shown to be of moderate acute toxicity by the oral and inhalation routes. It is highly acutely toxic when applied to the skin or eye and is considered corrosive. " EPA
