Nalco 2593 Msds May 2026

The MSDS cites both product and component data:

Target organs: Eyes, skin, respiratory tract, and gastrointestinal tract (if ingested).

| Property | Value | |----------|-------| | Appearance | Clear to hazy liquid | | Color | Colorless to pale yellow | | Odor threshold | Not available | | pH (100%) | 2.0 - 4.0 | | Melting point | ~ -5°C (fluid down to freezing) | | Boiling point | ~ 100°C (water component) | | Flash point | > 200°F (non-flammable) | | Specific gravity | 1.15 – 1.25 (water = 1) | | Viscosity | Low (similar to water) | | VOC content | 0% (water-based) |

According to the MSDS, NALCO 2593 is an aqueous solution of organic phosphonates and polymers. It is primarily designed to:

Appearance: Clear to hazy, colorless to pale yellow liquid
Odor: Mild, characteristic of organic chemicals
pH (as supplied): Typically 2.0 – 4.0 (acidic)
Solubility: Fully miscible in water nalco 2593 msds

The product identifier on the MSDS may also list synonyms such as “Scale Inhibitor 2593” or “Cooling Water Additive 2593.”

NALCO 2593 is a specialized industrial chemical formulation widely used in water treatment programs, particularly for scale and deposit control in boiler systems and cooling towers. While the product itself is engineered for efficiency, understanding its Material Safety Data Sheet (MSDS)—now more commonly referred to as the Safety Data Sheet (SDS) under GHS (Globally Harmonized System)—is not just a regulatory requirement; it is a critical component of workplace safety and risk management.

If you are searching for the NALCO 2593 MSDS, you likely need detailed information on chemical composition, first-aid measures, firefighting guidelines, accidental release protocols, and toxicological data. This article serves as an educational deep-dive into what you will find on that document and why each section matters for your operations.

Important Note: This guide provides a general interpretation of typical data found on an MSDS/SDS for phosphonate/polymer-based scale inhibitors. The actual, legally binding NALCO 2593 MSDS must be obtained directly from NALCO Water (an Ecolab company) or your authorized distributor. Always refer to the latest version for specific batch-related data. The MSDS cites both product and component data:

Do not rely on third-party summary websites for actual compliance. To get the official, legally current NALCO 2593 MSDS:

Pro tip: Check the “Revision Date” on the SDS. If it’s older than 3 years, request a new copy. Regulations (e.g., OSHA, EU CLP) evolve.

The MSDS for NALCO 2593 lists the active ingredients as proprietary but typically includes:

| Component | CAS Number | Concentration (% by weight) | |------------|------------|-----------------------------| | Phosphonic acid derivative | Proprietary (e.g., 2809-21-4 for etidronic acid) | 10 – 30% | | Acrylic copolymer | Proprietary (e.g., 9003-04-7) | 5 – 15% | | Water | 7732-18-5 | Balance | | Property | Value | |----------|-------| | Appearance

No hazardous impurities at levels requiring disclosure (≥0.1% for carcinogens, ≥1% for other hazards) are typically listed.

| Exposure Limit | Value | |----------------|-------| | NALCO 2593 (as a mixture) | No specific OSHA PEL or ACGIH TLV. | | Component (phosphonate) | Manufacturer recommends 10 mg/m³ (total dust) – but for liquid, use engineering controls. |

Engineering controls: Local exhaust ventilation (LEV) or closed systems.
