Nalco 8506 Plus Msds -

The SDS establishes Occupational Exposure Limits (OELs). Since Nalco 8506 Plus is a mixture, the limits are based on its components.

| Component | OSHA PEL | ACGIH TLV | | :--- | :--- | :--- | | Sulfuric acid | 1 mg/m³ | 0.2 mg/m³ (thoracic) | | Phosphoric acid | 1 mg/m³ | 1 mg/m³ |

Given that Nalco 8506 Plus is a liquid with low vapor pressure, inhalation risk primarily comes from mists created during high-speed mixing, tank filling, or spray applications.

Recommended PPE Ensemble:


NALCO 8506 Plus is generally classified as a moderate irritant. According to most available SDS versions:

Stable under normal storage conditions but decomposes when heated.

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: nalco 8506 plus msds

| 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.


Typically 12–18 months from date of manufacture. Degradation can cause pressure buildup in sealed containers – vent periodically if stored long-term. The SDS establishes Occupational Exposure Limits (OELs)
