Nalco 73385 is a specialized broad-spectrum, non-oxidizing biocide primarily used in industrial water systems to manage biological contamination. As a product of Nalco Water, an Ecolab company, its formulation and safety protocols are detailed in its Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS), which serves as a critical regulatory document for workplace safety and environmental protection. Product Overview and Application
Nalco 73385 is engineered for use in recirculating cooling towers and closed-loop systems. Its primary function is the control of:
Slime-forming bacteria, which can cause fouling and reduce heat transfer efficiency.
Sulfate-reducing bacteria, which are often responsible for microbiologically influenced corrosion (MIC) in metal piping.
The product is particularly valued for its persistency and efficacy at elevated pH levels, making it highly effective in closed water loops where other biocides might lose potency. Physical and Chemical Properties
According to typical product data sheets, Nalco 73385 possesses the following characteristics: Physical Form: Liquid, appearing colorless to yellow. Odor: Pungent or sweet. nalco 73385 msds
pH (Neat): Approximately 3.7 to 13.0 (varying by specific regional formulation or concentration). Density: Approximately 1.13 kg/L to 1.20 kg/L. Solubility: Complete in water. Flammability: Non-flammable and non-combustible. Safety and Hazard Identification

While specific data varies by concentration, typical safety profiles for similar Nalco non-oxidizing biocides include: Safety Data Sheets - SDS - MSDS - Ecolab
In the world of industrial water treatment, few chemicals are as specialized—and as potentially hazardous—as concentrated corrosion inhibitors. Nalco 73385 is one such product: a high-performance molybdate-based corrosion inhibitor used primarily in closed cooling water systems, chilled water loops, and engine jacket water systems. While the product is essential for preventing costly metal degradation, its chemical potency demands rigorous safety protocols.
For any facility using Nalco 73385, the MSDS (Material Safety Data Sheet)—now officially known as the SDS (Safety Data Sheet) under GHS—is not just a regulatory formality; it is the operational bible for safe handling. This article provides a deep dive into the Nalco 73385 MSDS, breaking down every critical section, from hazard identification to accidental release measures. Immediately flush eyes with plenty of water for
Note: Always refer to the most current SDS issued by Ecolab/Nalco Water. Product formulations can change, and regional regulations (OSHA, REACH, TSCA) may require different data. This article is for educational purposes based on standard historical data for Nalco 73385.
Do not land-apply, incinerate without scrubbers, or pour down the drain.
Recommended disposal: Contact a licensed hazardous waste transporter. Nalco 73385 may qualify as RCRA hazardous waste code D002 (Corrosive - pH <2 or >12.5) . Some states also list molybdenum as a toxic metal.
Dilution is not disposal – diluting to lower pH does not remove molybdenum from the waste stream.
Empty containers: Triple rinse with water, and treat the rinse water as hazardous waste. Crush or recycle steel drums only after removing all labels and verifying no residue remains.
