: Mists or vapors are highly irritating to mucous membranes and the upper respiratory tract. 3. First Aid Measures
Primarily manufactured by Ecolab / Nalco Water , NALCO 77352 is engineered for micro-organism control in industrial water systems, helping maintain heat transfer efficiency and prevent microbial corrosion. Because it is a powerful non-oxidizing biocide, strict adherence to its Safety Data Sheet (SDS) is mandatory for regulatory compliance, workplace safety, and environmental protection. Chemical Composition and Active Ingredients
According to the technical and safety profiles available on Scribd's Nalco 77352 Documentation , the formula relies on a powerful mixture of . The primary active constituents include:
Very toxic to aquatic life with long-lasting effects. Do not discharge directly into natural waterways. 3. Physical and Chemical Properties nalco 77352 sds
The core hazard profile of the product stems from the following active chemical percentages listed in Section 3 of the SDS:
The SDS provides the following first aid recommendations:
NALCO 77352 is typically used in —specifically for cooling towers, boilers, or influent water systems. It is designed to prevent scale, corrosion, and fouling. Because it is a proprietary formulation, the exact chemical ingredients are often listed as “trade secret” on the SDS, but the hazards are fully disclosed. : Mists or vapors are highly irritating to
Here is a breakdown of what that SDS contains, why it matters, and how to get the official document immediately.
: Harmful if swallowed or drawn into lungs as an aerosol mist. It can burn the linings of the mouth, esophagus, and gastrointestinal tract. Critical First Aid Measures Exposure Route Immediate Workplace Actions Required Eye Contact
Unlike common oxidizing alternatives like chlorine or bromine, NALCO 77352 does not break down rapidly at elevated pH scales. This makes it an ideal pick for modern alkaline water chemistry configurations. Furthermore, its stabilization system does not rely on copper chemistry, meaning operations can introduce it into multi-metal networks without accelerating galvanic degradation. Chemical Composition and Active Ingredients Because it is a powerful non-oxidizing biocide, strict
This technical overview covers the critical safety parameters, chemical composition, hazard identifications, and operational precautions outlined in the official Ecolab SDS Database . 1. Product Identification and Chemical Composition
It wasn't just an irritant. According to the SDS, NALCO 77352 contained a modified amine blend that, while stable in neutral pH, could undergo rapid exothermic decomposition if mixed with even trace amounts of oxidizing agents. The decomposition released a colorless, odorless gas—nitrogen dioxide’s precursor—which was both toxic and explosive at certain concentrations.
