Because it is a concentrated chemical mixture containing Potassium Hydroxide, the SDS highlights significant safety risks, including severe skin burns and eye damage.
Below is a review of the key safety and technical specifications based on the latest available documentation (updated as of late 2018/early 2019 versions). ⚠️ Hazard Overview & Safety
The product is classified under the Globally Harmonized System (GHS) with the following primary hazards:
Corrosive to Metals: Category 1 (may be corrosive to aluminum, copper, and zinc). Acute Toxicity (Oral): Category 4 (harmful if swallowed). Skin Corrosion: Category 1A (causes severe skin burns).
Serious Eye Damage: Category 1 (causes irreversible eye damage). Required Personal Protective Equipment (PPE) Eyes: Safety goggles and a full-face shield are mandatory.
Skin: Standard chemical-resistant gloves (e.g., Nitrile) and protective clothing.
Respiratory: Use only with adequate ventilation; respirators may be needed if concentrations exceed exposure limits. 🧪 Chemical Composition & Properties
Nalco 77225 is an internal boiler treatment that uses a combination of phosphate residuals and Transport Plus polymer technology. Concentration (%) Potassium Hydroxide 10 – 30% Tetrapotassium Pyrophosphate 10 – 30% Physical Data Appearance: Light yellow liquid with an ammoniacal odor. pH: >13 (highly alkaline). Density: 1.46 – 1.50 g/cm³ at 25°C. Solubility: Completely soluble in water. 🛠️ Operational Applications
Nalco 77225 is primarily used for scale control in boilers operating at pressures up to 40 barg.
Mechanism: Complex phosphates react with calcium and magnesium, while organic polymers transport these minerals through the boiler to prevent adherent deposits.

Nalco 77225 Safety Data Sheet: Updated Safety and Handling Guidelines
Nalco 77225 is a high-performance internal boiler treatment designed to prevent the formation of adherent scale. It achieves this through a sophisticated combination of phosphate residual programs and Transport Plus polymer technology, which ensures the transport of minerals like calcium, magnesium, and iron through the system to be safely removed via blowdown.
Because this product is highly alkaline and corrosive, staying updated with its Safety Data Sheet (SDS) is critical for maintaining workplace safety and regulatory compliance. Core Safety Classifications and Hazards
Under the Globally Harmonized System (GHS), Nalco 77225 carries several severe hazard classifications:
Corrosive to Metals (Category 1): May be corrosive to certain metals, requiring specific storage materials.
Acute Toxicity (Oral, Category 4): Harmful if swallowed; can cause severe digestive tract burns.
Skin Corrosion (Category 1A): Causes severe skin burns and immediate tissue damage.
Serious Eye Damage (Category 1): Risk of irreversible eye damage and permanent vision impairment. Chemical Composition
The effectiveness and the hazards of Nalco 77225 are driven by its primary active ingredients:
Tetrapotassium Pyrophosphate (10 – 30%): A complex phosphate used for scale inhibition.
Potassium Hydroxide (10 – 30%): A strong base responsible for the product's high pH (>13) and corrosive nature. Critical Handling and First Aid Measures
Due to its high alkalinity, immediate action is required in the event of exposure: Exposure Type Immediate Action Required Eye Contact
Rinse immediately with plenty of water, including under the eyelids, for at least 15 minutes. Remove contact lenses if present. Seek medical attention immediately. Skin Contact
Wash off immediately with plenty of water for at least 15 minutes. Use mild soap if available. Discard or thoroughly clean contaminated clothing and shoes. Ingestion
Rinse mouth with water. Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Seek emergency medical care immediately. Inhalation
Remove the person to fresh air. Treat symptomatically and seek medical attention if symptoms like respiratory irritation or coughing occur. Safe Storage and Compatibility
Storing Nalco 77225 correctly is essential to prevent container failure and dangerous reactions.
Temperature Limits: The maximum storage temperature is 65°C (149°F). Storing above this for long periods can lead to the formation of a white precipitate.
Incompatibilities: Keep away from strong acids, which can cause violent exothermic reactions. Materials of Compatibility:
Recommended: Stainless Steel (304 & 316L), HDPE, PVC, Polypropylene, and Viton.
Avoid: Aluminum, Copper, Brass, Zinc, and mild steel, as the product can react with these metals to produce flammable hydrogen gas. Required Personal Protective Equipment (PPE) When handling Nalco 77225, workers must use the following:
Eye/Face Protection: Chemical splash goggles and a face shield.
Skin Protection: Neoprene, Nitrile, or PVC gloves and standard protective clothing (aprons or suits).
Respiratory Protection: Not normally needed under general ventilation, but required if air concentrations exceed occupational exposure limits (Ceiling: 2 mg/m³ for Potassium Hydroxide). How to Obtain the Latest SDS

Primary Function: Scale inhibition and boiler integrity maintenance.
Physical Form: Light yellow liquid with a slight ammoniacal odor.
Key Characteristics: Highly alkaline (pH ~13.5) and fully soluble in water. 2. Updated Hazard Identification (GHS Classification)
According to the latest Global Harmonized System (GHS) standards, Nalco 77225 is classified as a hazardous and corrosive substance. Hazard Category Description Corrosive to Metals Category 1; May be corrosive to metals. Acute Toxicity Category 4; Harmful if swallowed. Skin Corrosion Category 1A/1B; Causes severe skin burns. Serious Eye Damage Category 1; Causes irreversible eye damage. 3. Chemical Composition & Ingredients
The efficacy and hazards of Nalco 77225 stem from its concentrated alkaline components. The primary active ingredients typically include:
Potassium Hydroxide (CAS 1310-58-3): 10% – 30% concentration. This provides the alkalinity necessary for treatment but is the main driver of its corrosive nature.
Tetrapotassium Pyrophosphate (CAS 7320-34-5): 10% – 30% concentration. Acts as a buffering and sequestering agent.
Proprietary Polymers: Specialized "Transport Plus" polymers that keep minerals suspended to prevent scaling. 4. Essential First Aid Measures
In the event of accidental exposure, immediate action is required to minimize tissue damage.
Eye Contact: Immediately rinse with water for at least 15 minutes, holding eyelids open. Seek urgent medical attention from a Poison Center or doctor.
Skin Contact: Remove contaminated clothing instantly and rinse the affected skin with plenty of water or use a safety shower.
Inhalation: Move the individual to fresh air. If breathing is difficult, seek medical help immediately.
Ingestion: Rinse mouth with water. Do NOT induce vomiting. Call a physician or poison control center immediately. 5. Safe Handling and Storage Protocols
Due to its high pH and corrosive properties, Nalco 77225 requires specific storage conditions and materials.
Personal Protective Equipment (PPE): Always wear chemical splash goggles, a full face shield, and chemical-resistant gloves (e.g., Neoprene or Butyl Rubber).
