Closed-loop cooling systems (it contains no copper, making it safe for these environments). Air washers and brewery pasteurizers. turquoise-az.com Key Safety Insights from the MSDS
The effectiveness of NALCO 77352 stems from its active blend of isothiazolinones.
Closed-loop cooling systems (safe for use as it does not contain copper stabilizers).
Corrosive symbol (GHS05)
is a specialized biocidal product manufactured by Ecolab (Nalco), frequently utilized in industrial water treatment applications to control microbial growth. For safety professionals, facility managers, and operators, understanding the NALCO 77352 Safety Data Sheet (SDS) —formerly known as the Material Safety Data Sheet (MSDS)—is critical for compliant handling, storage, and emergency response.
Wear safety glasses with side shields or chemical splash goggles.

Immediately flush eyes with running water for at least 15 minutes, holding eyelids open. Get medical attention immediately.
Understanding NALCO 77352: A Detailed Guide to Safety Data Sheets (SDS) and Handling
The —now standardly referred to as the Safety Data Sheet (SDS) under the Globally Harmonized System (GHS)—is a critical legal and technical document required for industrial facilities utilizing this specific chemical formulation. NALCO 77352 is a highly effective, broad-spectrum, non-oxidizing biocide manufactured by Ecolab / Nalco Water . It is primarily engineered to control microbial growth, biofouling, and microbial corrosion in industrial water systems, including open recirculating cooling towers, closed-loop cooling systems, air washers, and brewery pasteurisers. Closed-loop cooling systems (it contains no copper, making
The product is a biocide containing active components of isothiazolin-3-ones. For detailed chemical compositions, always refer to the specific SDS provided by Ecolab. 3. First Aid Measures If exposure occurs, immediate action is required:
