user wants a long article for the keyword "nalco 8514 plus msds". My search plan is divided into two rounds. In Round One, I need to search for the MSDS, technical data, product description, and usage applications. I'll start with the first set of searches. search results show some relevant pages. I'll open result 0, result 1, and result 2 from the first search, as they seem to have product information. I'll also open result 0 from the second search and result 0 from the third search. PDF from autobrillante.com appears to be a safety data sheet (SDS) in Spanish. It contains sections on identification, hazards, and composition. This is a valuable source for the article. I'll also open result 2 from the second search, which is a PDF in Spanish, and result 0 from the third search, which is a page about Russian analogues. I'll also search for more specific technical data. search results for "Nalco 8514" biocide cooling water show a PDF, but it's not the SDS. The search for "8514 plus" nalco water treatment shows a myhealthbox.eu page which might contain product information. I'll open result 0 from that search. I'll also open result 0 from the search "nalco 8514 plus msds request". myhealthbox.eu page seems to be a product leaflet, but it might contain some SDS information. I'll also open the quimicasmorales.com page from result 0 of the search "NALCO 8514" safety data sheet. PDF from quimicasmorales.com is a technical bulletin. It contains useful information about the product's benefits and applications. The PDF from ureaknowhow.com contains a table with composition and properties. I'll now proceed to write the article. The article will be structured with an introduction, sections on chemical product identification, hazard identification, composition/information on ingredients, first aid measures, firefighting measures, accidental release measures, handling and storage, exposure controls/personal protection, physical and chemical properties, stability and reactivity, toxicological information, ecological information, disposal considerations, transport information, regulatory information, and other information. I will cite the sources appropriately. Now I will write the article. following detailed article consolidates all available information from the official Safety Data Sheet (SDS), technical bulletins, and distributor data for NALCO® 8514 PLUS . NALCO® 8514 PLUS: Comprehensive Safety Data Sheet (SDS/MSDS) Guide NALCO® 8514 PLUS is a powerful, non-oxidizing biocide manufactured by Nalco Water, an Ecolab company. It is formulated as a quaternary ammonium compound-based liquid used for microbiological control in various industrial water systems. This detailed guide analyzes its Safety Data Sheet (SDS), also known as Material Safety Data Sheet (MSDS), covering hazard identification, composition, safe handling, first aid, physical properties, and environmental impact based on official documentation. 1. Chemical Product Identification and Manufacturer According to the official Safety Data Sheet, the product is identified as NALCO® 8514 PLUS , a liquid biocide mixture primarily used for cooling water treatment in industrial and professional settings. The product is manufactured by Nalco Ltd, with global and local company information provided in the SDS, including the UK headquarters and local subsidiaries. Nalco Water, now a part of Ecolab, is a leading global supplier of water, energy, and air improvement solutions, serving over 70,000 customers worldwide. 2. Hazard Identification The SDS for NALCO 8514 PLUS classifies the substance as corrosive according to the European CLP Regulation (EC) No 1272/2008. The hazards are serious, requiring strict handling protocols. Classification: Skin Corrosion Category 1B and Serious Eye Damage Category 1. Hazard Statements (H314 & H318): The product causes severe skin burns and eye damage. The signal word on the label is " Danger ". Precautionary Statements: The SDS lists crucial prevention and response measures:
Prevention: Wear protective gloves, clothing, eye, and face protection. Do not breathe mists or vapors. Response in case of ingestion: Rinse mouth. Do NOT induce vomiting. Response in case of skin contact: Remove all contaminated clothing immediately. Rinse skin with water. Response in case of inhalation: Remove person to fresh air. Call a poison center or doctor immediately if breathing difficulties occur. Response in case of eye contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing.
3. Composition and Chemical Information The key active ingredient in NALCO 8514 PLUS is Didecyldimethylammonium chloride (also known as DDAC), a quaternary ammonium compound responsible for its biocidal action. The product also contains isopropanol as a solvent. | Component | CAS Number | Approx. Conc. (W/W) | Classification (CLP) | | :--- | :--- | :--- | :--- | | Didecyldimethylammonium chloride | 7173-51-5 | 10% - < 25% | Acute Tox. 4 (Oral), Skin Corr. 1B, Eye Dam. 1, Aquatic Acute 1, Aquatic Chronic 1 | | Isopropanol (Isopropyl alcohol) | 67-63-0 | 5% - 10% | Flam. Liq. 2, Eye Irrit. 2, STOT SE 3 | Physical State: Liquid. Appearance: Colorless. Odor: Alcoholic. The biocidal activity of NALCO 8514 PLUS is not the result of a single mechanism but a synergistic interaction of its components. Quaternary ammonium compounds act by disrupting the cell membranes of microorganisms, leading to cell lysis and death. 4. First Aid Measures Given the corrosive nature of the product, immediate and proper first aid is critical. The SDS details the following measures:
Inhalation: Remove person to fresh air. If breathing is irregular or has stopped, administer artificial respiration. Get immediate medical attention. Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash contaminated clothing before reuse. Get immediate medical attention. Eye Contact: Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get immediate medical attention. Ingestion: Do not induce vomiting. Rinse mouth with water. Never give anything by mouth to an unconscious person. Get immediate medical attention. nalco 8514 plus msds
Acute Toxicity Estimates:
Oral LD50 (Rat): > 2000 mg/kg for the mixture. For the active component, Didecyldimethylammonium chloride, the oral LD50 in rats is 1150 mg/kg. Dermal LD50 (Rabbit): For Didecyldimethylammonium chloride, the dermal LD50 is 2930 mg/kg, indicating moderate acute toxicity through skin contact.
5. Firefighting Measures The SDS for NALCO 8514 PLUS classifies the product with a flash point of 36°C (closed cup), making it a combustible liquid. user wants a long article for the keyword
Suitable Extinguishing Media: Use alcohol-resistant foam, carbon dioxide (CO2), dry chemical, or water spray. Specific Hazards: During a fire, toxic and corrosive fumes including oxides of carbon and nitrogen may be generated.
6. Accidental Release Measures In case of a spill or leak, the following personal protective equipment (PPE) is mandatory: full protective clothing, including gloves and goggles or a face shield. Key steps include:
Containment: Prevent the material from entering drains, sewers, or waterways. Cleaning: Absorb spill with inert material (e.g., sand, vermiculate) and collect in a suitable, labeled container for disposal. Environmental Precautions: This product is toxic to aquatic life. It must be prevented from contaminating soil or water bodies. I'll start with the first set of searches

Keep away from heat, sparks, and open flames. Storage: Store in a cool, dry, well-ventilated area away from incompatible materials (strong oxidizers, alkalis). Keep containers tightly closed when not in use. The product has a freezing point of -7 °C (19.4 °F). 8. Exposure Controls and Personal Protection The SDS establishes the following exposure limits for key ingredients:
Isopropanol: TWA (8-hour) of 400 ppm (983 mg/m³) and STEL (15-minute) of 500 ppm (1230 mg/m³). Didecyldimethylammonium Chloride: Occupational exposure limits are typically not established, but worker protection should be prioritized.
