Nalco 2593 Msds ✯ | LEGIT |

Before analyzing the MSDS, it is essential to understand the product’s role. NALCO 2593 is typically described as a liquid scale inhibitor and deposit control agent. It is formulated with organophosphonates, acrylic copolymers, and inert carriers.

Common Applications:

Why the MSDS Matters for This Product:
Although NALCO 2593 is not classified as an extremely hazardous material (e.g., it lacks acutely toxic gases or pyrophorics), it is corrosive to eyes and potentially harmful if ingested. The MSDS provides the nuance needed to handle it safely without over- or under-engineering controls.


The MSDS for NALCO 2593 clearly identifies this product as a corrosive, acidic scale inhibitor that demands respect and rigorous handling procedures. While highly effective in controlling scale in industrial cooling systems, its potential to cause severe eye and skin damage, along with moderate aquatic toxicity, requires facilities to implement: nalco 2593 msds

Always consult the actual NALCO 2593 Safety Data Sheet provided by Nalco Water — not an archived or third-party copy — before handling, storing, or disposing of this chemical. Compliance with OSHA’s HazCom Standard (29 CFR 1910.1200) requires that your specific MSDS be accessible, legible, and less than 5 years old.

Nalco 2593 is a liquid microbiocide used in industrial recirculating cooling-water systems to control bacteria, fungi and algae. Active ingredients listed in regulatory records are 5‑chloro‑2‑methyl‑4‑isothiazolin‑3‑one (CMIT) ~1.15% and 2‑methyl‑4‑isothiazolin‑3‑one (MIT) ~0.35%; the rest are inert ingredients. The product is registered as a potent biocide and carries strong hazard warnings.

  • Product Use: Industrial Water Treatment.
  • Chemical Family: Mixed phosphonate/nitrite/borate blend (Typical formulation profile).
  • The MSDS provides strict, time-sensitive first-aid protocols due to the corrosive nature of NALCO 2593.

    | Route of Exposure | Immediate Action | |------------------|------------------| | Inhalation | Remove to fresh air. If breathing is difficult, give oxygen. If stopped, perform artificial respiration. Seek medical attention if irritation persists. | | Skin contact | Remove contaminated clothing immediately. Rinse skin with plenty of water for at least 15–20 minutes. Wash clothing before reuse. Seek medical help for burns. | | Eye contact | Hold eyelids open and rinse cautiously with water for at least 30 minutes. Remove contact lenses if present. Immediate medical evaluation is required. | | Ingestion | Do NOT induce vomiting. Rinse mouth with water. If conscious, drink 1–2 glasses of water to dilute. Never give anything by mouth to an unconscious person. Seek emergency medical attention. |

    Notes to physician: Symptomatic treatment. Corrosive injury may require esophagoscopy if ingestion occurred.
