The water and chelating agents are generally low toxicity, but the concentrated molybdate solution is alkaline (pH between 11.5 and 13.0), which drives the corrosive classification.
| Property | Typical value | |-----------|----------------| | Appearance | Clear to pale yellow liquid | | pH (as supplied) | 2.0 – 4.0 (acidic) | | Specific gravity | 1.10 – 1.20 | | Solubility | Fully miscible in water | | VOC content | 0% |
Reviewer’s note: The low pH is the primary hazard. Always add to water, never water to product, to avoid splashing. nalco 73385 msds
| Area | Minimum PPE | |------|-------------| | Eyes/Face | Chemical splash goggles (not safety glasses) | | Hands | Nitrile or neoprene gloves (tested for chemical resistance) | | Skin | Chemical-resistant apron and closed-toe boots | | Respiratory | None under normal use; if misting, use N95 or half-face respirator with particulate filter |
Nalco 73385 is a high-performance industrial water treatment chemical, typically used as a scale inhibitor, dispersant, or corrosion control agent in cooling towers, boilers, and wastewater systems. Manufactured by Nalco Water (an Ecolab company), this product is essential for maintaining thermal efficiency and asset integrity in heavy industries such as power generation, petrochemicals, and HVAC. The water and chelating agents are generally low
However, with its effectiveness comes chemical risk. The Material Safety Data Sheet (MSDS) — now formally known as the SDS (Safety Data Sheet) under GHS (Globally Harmonized System) — is the legally required document that communicates the hazards, handling protocols, and emergency measures for Nalco 73385. Accessing and understanding the Nalco 73385 MSDS is not just a regulatory checkbox; it is a critical safety practice.
Note: As of June 1, 2015, OSHA aligned its Hazard Communication Standard (HCS 2012) with GHS. While many still search for "MSDS," the official current document is the SDS. This article uses both terms but focuses on the modern SDS format. Note: As of June 1, 2015, OSHA aligned
Reviewer’s note: This is the weakest point in the SDS – product persists in the environment. Use in closed-loop systems or with proper blowdown treatment is strongly recommended.
Before opening a drum or programming a chemical feed pump, every facility must have the latest SDS on file. Here is why the Nalco 73385 SDS is indispensable:

Reviewer’s note: The product is generally considered low acute toxicity to humans, but concentrated forms require PPE. Eye protection is mandatory.
