While the exact formulation is proprietary, the SDS is legally required to list hazardous ingredients above certain thresholds. For Nalco 8506 Plus, the typical components include:
| Chemical Name | CAS Number | Typical Weight % | Hazard Notes | | :--- | :--- | :--- | :--- | | Phosphonic acid (e.g., ATMP or HEDP) | 2809-21-4 | 20 – 40% | Corrosive; chelating agent. | | Acrylic copolymer | Proprietary | 10 – 20% | Low hazard, but enhances dispersancy. | | Inorganic acid (e.g., Sulfuric or Phosphoric) | 7664-93-9 or 7664-38-2 | 1 – 5% | Increases corrosivity; adjusts pH. | | Water | 7732-18-5 | Balance | Non-hazardous vehicle. |
Critical insight: The combination of phosphonic acid and a mineral acid creates a low-pH solution (typically <2.0). This is why the material is dangerous to living tissue and reactive with bases.
In the event of exposure, the following standard first aid measures generally apply to industrial biocides, though the official SDS must be consulted for specific neutralizing agents:
The Nalco 8506 Plus MSDS is not a document to be stored in a dusty binder in the maintenance shed. It is a living operational manual. For any facility using this effective corrosion inhibitor, the following actions are non-negotiable:
By respecting the chemistry outlined in the Safety Data Sheet, you can safely leverage the performance benefits of Nalco 8506 Plus—protecting both your cooling water system and, more importantly, your workforce.
Always download the most recent SDS from the Ecolab / Nalco Water website or request it from your supplier, as formulations and regulatory classifications can change. nalco 8506 plus msds
