The MSDS for NALCO 2593 clearly identifies this product as a corrosive, acidic scale inhibitor that demands respect and rigorous handling procedures. While highly effective in controlling scale in industrial cooling systems, its potential to cause severe eye and skin damage, along with moderate aquatic toxicity, requires facilities to implement:
Always consult the actual NALCO 2593 Safety Data Sheet provided by Nalco Water — not an archived or third-party copy — before handling, storing, or disposing of this chemical. Compliance with OSHA’s HazCom Standard (29 CFR 1910.1200) requires that your specific MSDS be accessible, legible, and less than 5 years old.

NALCO® 2593 is a hazardous, isothiazolinone-based microbiocide used primarily as an algaecide, slimicide, and disinfectant in industrial water systems. Due to its corrosive nature and toxicity, Safety Data Sheets (SDS) are strictly required for handling, though they are typically provided by Ecolab directly upon purchase rather than being hosted for general public download. Product Summary and Usage
Primary Function: Controls bacteria, fungi, and algae in industrial wastewater treatment, sewage systems, and cooling water systems (e.g., condensers and air washers).
Industrial Applications: It is certified by NSF International (Category G7) for treating boilers and cooling systems in food processing areas, provided the treated water or steam does not contact edible products. The MSDS for NALCO 2593 clearly identifies this
Chemical Nature: Liquid formulation containing active ingredients like 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one. Key Hazard Identifications
Based on safety data for this and similar Nalco biocides, the following risks are associated with NALCO 2593: Safety Data Sheets - SDS - MSDS - Ecolab
Before analyzing the MSDS, it is essential to understand the product’s role. NALCO 2593 is typically described as a liquid scale inhibitor and deposit control agent. It is formulated with organophosphonates, acrylic copolymers, and inert carriers. Always consult the actual NALCO 2593 Safety Data
Common Applications:
Why the MSDS Matters for This Product:
Although NALCO 2593 is not classified as an extremely hazardous material (e.g., it lacks acutely toxic gases or pyrophorics), it is corrosive to eyes and potentially harmful if ingested. The MSDS provides the nuance needed to handle it safely without over- or under-engineering controls.
