, a widely used cooling water treatment manufactured by Nalco Water (an Ecolab company). Product Overview Nalco 2000

is a liquid chemical blend primarily used as a corrosion inhibitor and scale suppressant in closed cooling systems, particularly for diesel engines. Its red, odorless formulation creates a protective film to prevent cavitation, liner pitting, and mineral scale buildup. Key Chemical Composition

According to Safety Data Sheets (SDS), the product is an aqueous solution containing several hazardous alkaline salts:

Sodium Nitrite (approx. 4–10%): The primary active inhibitor.

Sodium Tetraborate: Used for pH buffering and corrosion control.

Sodium Metasilicate: Provides aluminum protection and alkalinity.

Sodium Mercaptobenzothiazole: Specific yellow-metal (copper/brass) inhibitor. Hazard Identification

The Global Harmonized System (GHS) classifies this product as Harmful and an Irritant. SAFETY DATA SHEET NALCOOL® 2000

This guide summarizes the Safety Data Sheet (SDS) for Nalco 2000 (also known as Nalcool 2000), a corrosion inhibitor and scale suppressant used primarily in closed-loop cooling systems, such as diesel engines. 1. Product Identification & Composition

Nalco 2000 is a dark red, odorless liquid. It is alkaline, with a pH typically between 11.1 and 11.8. Key Active Ingredients:

Sodium Nitrite: Acts as a corrosion inhibitor but is toxic if ingested.

Sodium Tetraborate & Sodium Metasilicate: Provide alkalinity and further corrosion protection.

Sodium Mercaptobenzothiazole: An additional additive for metal protection. 2. Hazard Identification Nalco 2000 is classified as Harmful and an Irritant. SAFETY DATA SHEET NALCOOL® 2000

Section 12: Ecological Information (Environmental Impact)

Toxicity to Fish: LC50 (96-hour) is typically < 1 mg/L (Extremely toxic).
Biodegradability: Glutaraldehyde is biodegradable but takes time. Do not rely on rapid breakdown in the event of a spill.

Section 4: First Aid Measures (What to do in an emergency)

Because Nalco 2000 is corrosive and toxic, first aid must be immediate and aggressive:

Eye Contact: Hold eyelids open and rinse with plenty of water for at least 15 minutes. Seek immediate medical attention. Do not use ointments without medical advice.
Skin Contact: Remove contaminated clothing. Wash skin with soap and water for 15 minutes. If irritation or burning persists, call a doctor. Wash clothing before reuse.
Inhalation: If mist or vapor is inhaled, move person to fresh air. If breathing is difficult, administer oxygen. If breathing stops, give artificial respiration. Seek medical attention.
Ingestion: Do NOT induce vomiting. Rinse mouth. Give water to drink (if conscious). Vomiting may cause aspiration into the lungs, which can be fatal. Transport to a hospital immediately.

1. What “MSDS Nalco 2000” Actually Is

Nalco 2000 is a trade name (Ecolab/Nalco Water) for a liquid, cationic organic coagulant.
Used in clarification, wastewater treatment, and potable water production.
An MSDS (now called SDS – Safety Data Sheet) is a regulatory compliance document, not a research paper.

Environmental and disposal notes

Many water-treatment chemicals are harmful to aquatic organisms; avoid releases to sewage systems and surface waters.
Dispose of waste and contaminated containers per local, regional, and national regulations — consult the SDS for proper disposal codes.

Section 4: First-Aid Measures – Practical Guidance

This is one of the most consulted sections of the msds nalco 2000. Here is the standard advice:

Eye Contact: Immediately rinse eyes with plenty of water for at least 15 minutes, occasionally lifting upper and lower lids. Get medical attention if irritation persists.
Skin Contact: Wash contaminated skin with soap and water. Remove contaminated clothing and launder before reuse. If irritation develops, consult a physician.
Inhalation: If misted (e.g., during high-pressure spraying), move person to fresh air. Seek medical attention if coughing or discomfort continues.
Ingestion: Rinse mouth. Do NOT induce vomiting unless directed by medical personnel. Drink 1-2 glasses of water. Never give anything by mouth to an unconscious person.

Common Compliance Mistakes with Nalco 2000

Based on industrial audits, here are frequent errors:

Using the wrong gloves: Workers often use standard latex gloves, which degrade within minutes of contact with glutaraldehyde. Always use nitrile.
Ignoring the "sensitizer" risk: Even low-level vapors over time can cause occupational asthma. Ventilation is key.
Mixing with other chemicals: Unknowingly mixing Nalco 2000 with sodium hypochlorite (bleach) releases toxic gas.
Outdated MSDS: Nalco occasionally updates formulations. An MSDS older than 3 years may be invalid. Always download the latest from Ecolab’s website.

11. TOXICOLOGICAL INFORMATION (Estimates)

Oral LD50 (rat): >2000 mg/kg (slightly toxic)
Dermal LD50 (rabbit): >5000 mg/kg
Eye Irritation: Corrosive (irreversible damage)
Skin Sensitization: Possible (due to azoles)

Product overview

Nalco 2000 is a commercial/industrial chemical product family used for water treatment and process control (scale/corrosion inhibitors, dispersants, biocides and related chemistries). Exact composition and hazards depend on the specific Nalco 2000 formulation; “Nalco 2000” may be a trade name or part of a product code and requires the manufacturer’s Safety Data Sheet (SDS/MSDS) for precise information. msds nalco 2000
