The Nalco 8506 Plus Safety Data Sheet (SDS), formerly known as a Material Safety Data Sheet (MSDS), is a crucial document for industrial facilities using this cooling water biodetergent. It outlines the chemical’s composition, hazards, and safety protocols necessary for maintaining efficient, foul-free cooling systems while ensuring worker safety. Product Overview and Applications
Nalco 8506 Plus is a high-performance biodetergent specifically designed for open recirculating cooling systems subject to high-stress conditions. Unlike primary biocides, biodetergents like 8506 Plus act by dispersing oils, hydrocarbons, and silt, which prevents the formation of biofilms and helps keep heat exchanger surfaces clean. Key benefits of using Nalco 8506 Plus include:
Heat Transfer Efficiency: Prevents fouling to maintain optimal heat exchange.
Microbiological Control: Enhances the effectiveness of biocides by penetrating slime and silt deposits where microorganisms thrive.
Maintenance Cost Reduction: Prevents microbial-induced corrosion and expensive mechanical cleanings.
Regulatory Compliance: It is NSF Registered under category codes G5 and G7, making it acceptable for use in and around food processing areas provided there is no direct contact with edible products. Chemical Composition
The effectiveness of Nalco 8506 Plus is derived from its surfactant-based formulation. According to the GHS Safety Data Sheet, its primary active ingredients include:
Alcohols, C12-15, ethoxylated (10% – 30% concentration): A surfactant used for its cleaning and dispersing properties.
Sodium Xylenesulfonate (5% – 10% concentration): Acts as a hydrotrope to keep the formula stable and enhance its solvency. Physical and Chemical Properties Appearance: Clear to light yellow liquid. pH (Neat): Approximately 7.2 (Neutral). Relative Density: 1.0675 at 20°C.
Flash Point: >100°C (>212°F), indicating it is not classified as a flammable liquid under standard handling. Viscosity: 147.5 mPa.s at 20°C. Hazard Identification and First Aid
Nalco 8506 Plus is classified as a hazardous substance because it can cause serious eye damage. Route of Exposure Potential Health Effect First Aid Measure Eye Contact Causes serious eye damage and irritation.
Rinse immediately with water for at least 15 minutes. Seek immediate medical attention. Skin Contact
Can cause moderate irritation; prolonged contact may cause dermatitis. Wash off with soap and plenty of water. Ingestion May cause nausea, dizziness, or vomiting. Rinse mouth. Seek medical attention if symptoms occur. Inhalation High concentrations may cause dizziness or stupor. Remove to fresh air. Treat symptomatically. Safe Handling and Materials Compatibility
Because Nalco 8506 Plus is a concentrated chemical, proper storage and equipment selection are vital.
Personal Protective Equipment (PPE): Workers should always wear safety goggles, face shields, and chemical-resistant gloves (rubber or nitrile) when handling the neat product.
Compatible Materials: Storage tanks, pumps, and lines should be constructed from PVC, Polyethylene (PE), Teflon, or Stainless Steel.
Materials to Avoid: Do not use aluminum, brass, or carbon steel in direct contact with the undiluted product, as it may cause degradation or corrosion of these metals. Environmental and Disposal Considerations
While Nalco 8506 Plus is designed to improve water system sustainability by reducing water and energy waste, the concentrated product must be handled carefully. If spilled, it should be contained and disposed of according to local, state, and federal regulations. It may meet the criteria for hazardous waste under the Resource Conservation and Recovery Act (RCRA) depending on its concentration and state.
