NALCO 8506 Plus is generally classified as a moderate irritant. According to most available SDS versions:
Under the Globally Harmonized System (GHS), the SDS provides standardized hazard classifications. For Nalco 8506 Plus, the typical classifications are as follows:
According to the most recent Nalco 8506 Plus SDS, this product is classified as a Hazardous Chemical.
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.
These details help identify the product and predict behavior. NALCO 8506 Plus is generally classified as a
| Property | Value | | :--- | :--- | | Appearance | Clear to hazy, colorless to pale yellow liquid | | Odor | Mild, characteristic (acidic) | | pH (100%) | < 1.5 (Strongly acidic) | | Specific Gravity | 1.25 – 1.35 (Slightly heavier than water) | | Viscosity | Low (water-like to slightly syrupy) | | Solubility in Water | 100% soluble | | Volatile Organic Compounds (VOC) | 0% (Aqueous solution) | | Vapor Pressure | Same as water |
Product Name: Nalco® 8506 Plus Manufacturer: Nalco Water, an Ecolab Company Common Uses: Oxidizing microbiocide for cooling towers, industrial recirculating water, and pulp/paper mill systems. It controls slime-forming bacteria, Legionella, and biofilms.
Key Chemical Identity: Nalco 8506 Plus typically contains a stabilized solution of Sodium Dichloro-s-triazinetrione or a related chlorine-donor compound. Unlike uns Table stabilized chlorines, this product offers extended residual efficacy. These details help identify the product and predict behavior
Why the MSDS is Mandatory: Without the MSDS, you do not know the specific concentration, the exact stabilizing agents, or the correct personal protective equipment (PPE). A generic chlorine MSDS is insufficient.
Chlorine gas, hydrogen chloride, carbon monoxide.
