The compound is classified as a . It can cause moderate eye and skin irritation upon direct contact. Its chemical configuration creates a protective barrier over metal boundaries. This stops dissolved oxygen and corrosive ions from degrading closed-loop systems. Primary Applications and Industry Use 1. Closed-Loop Cooling Water Treatment
NALCO 93033 holds under Category Code G7. NSF registration under this category specifies that the product is acceptable for use in industrial water treatment (boilers, cooling systems) where there is no potential contact with edible products in food processing areas. It also confirms adherence to relevant FDA regulations for ingredient use (21 CFR).
Because industrial water chemistries present potential health risks upon direct exposure, personnel must utilize standard Safety Data Sheet (SDS) workplace protocols. While specific formulations are proprietary, standard safety metrics for industrial cooling additives mandate defensive handling: Nalco 93033 Chemical Treatment Overview | PDF - Scribd nalco 93033
provided by Ecolab/Nalco for the specific batch and product before handling. Water treatment chemistry should only be applied by trained professionals who understand the specific metallurgy and operating pressures of the boiler system.
Based on technical data, NALCO 93033 typically presents as a clear, light-yellow liquid. The compound is classified as a
The approval is a "derived authorization," meaning it shares an identical formulation with the product (CAS number 7681-52-9).
Indirectly. By removing scale and biofilm (which harbor bacteria), it supports biocide efficacy. However, you still need a secondary biocide (e.g., chlorine, DBNPA) specifically for Legionella control. This stops dissolved oxygen and corrosive ions from
Always consult your local wastewater treatment authority regarding phosphate discharge limits. You may need to remove phosphates via precipitation (lime) if limits are stringent (<1 mg/L PO₄).
: It is frequently mentioned in maintenance manuals for high-precision machinery, such as
Cooling water corrosion inhibitor and additive.
