Nalco 73385 Msds -

NALCO 73385 is a broad-spectrum, non-oxidizing biocide designed for use in recirculating cooling towers and closed-loop systems. It is specifically engineered to control slime-forming and sulfate-reducing bacteria. Key Features & Performance Effective Biological Control: Targets bacteria that cause biofilms and under-deposit corrosion in water systems. High pH Stability: Maintains efficacy and persistency even in elevated pH environments, making it suitable for closed water loops. Broad-Spectrum Activity: Controls a wide range of microorganisms, including those resistant to standard oxidizing treatments. Technical & Physical Properties Based on typical Safety Data Sheet (SDS) specifications for this product: Physical Form: Liquid. Appearance: Typically colorless to yellow. Odor: Pungent or mild. Solubility: Completely soluble in water. pH (Neat): Approximately 3.7. Density: ~1.13 kg/L at 20°C. Freezing Point: –21°C (–5.8°F). Safety & Handling Highlights Hazard Classification: As a biocide, it is generally corrosive and can cause serious eye and skin irritation upon contact. Personal Protection: Use of chemical-resistant gloves (such as PVC), goggles, and protective clothing is recommended during handling. Environmental Impact: It is toxic to aquatic life; direct discharge into natural waterways or public water supplies should be avoided. Storage: The product is non-flammable and stable under normal conditions but should be protected from extreme temperatures. Others: NALCO 73385 - HKCT Malaysia

NALCO 73385 MSDS: A Comprehensive Guide to Safety, Handling, and Compliance Introduction In the world of industrial water treatment, NALCO 73385 is a recognized name. As a specialized cooling water additive, it plays a critical role in controlling scale, corrosion, and fouling in large-scale cooling towers, heat exchangers, and closed-loop systems. However, no discussion of its technical application is complete without understanding its associated safety documentation. The NALCO 73385 MSDS (Material Safety Data Sheet), now more commonly referred to as the SDS (Safety Data Sheet) under the Globally Harmonized System (GHS), is the single most important document for anyone who manufactures, transports, stores, or uses this chemical. This article provides an exhaustive breakdown of the NALCO 73385 MSDS. We will cover its 16 standardized sections, hazard identification, first-aid measures, accidental release protocols, and long-term storage requirements.

Disclaimer: This article is for informational purposes only. The specific NALCO 73385 MSDS in your possession should always be the most current version provided by Nalco Water (an Ecolab company). Do not use this guide as a substitute for the actual manufacturer-issued SDS.

Part 1: What is NALCO 73385? (Product and Company Identification) According to Section 1 of the NALCO 73385 MSDS, the product is identified as a liquid water treatment formulation. It is typically a clear to hazy amber liquid with a mild chemical odor. Common Uses: nalco 73385 msds

Scale and corrosion inhibition in recirculating cooling water systems. Deposit control in open recirculating and once-through cooling systems. Stabilization of hardness salts (calcium carbonate, calcium phosphate).

Manufacturer Information:

Supplier: Nalco Water, an Ecolab Company Emergency Telephone Number (North America): 1-800-424-9300 (CHEMTREC) or 1-630-305-1000 (Nalco) High pH Stability: Maintains efficacy and persistency even

It is vital to note that the exact composition is often a proprietary blend, but the MSDS will list hazardous ingredients.

Part 2: Hazard Identification – What Does the MSDS Warn You About? The NALCO 73385 MSDS typically classifies this product as a Class D2B material (toxic, corrosive, or irritant) under older systems, but under GHS, one of the primary hazards is Skin Corrosion/Irritation . GHS Hazard Classifications:

H315: Causes skin irritation. H319: Causes serious eye irritation. H317: May cause an allergic skin reaction (depending on specific organic additives). Appearance: Typically colorless to yellow

Signal Word: WARNING Precautionary Statements from the MSDS:

P280: Wear protective gloves (e.g., nitrile rubber), protective clothing, and eye/face protection (safety goggles or face shield). P302 + P352: IF ON SKIN: Wash with plenty of soap and water. P305 + P351 + P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing.
