Note: The MSDS will state that specific chemical identity is withheld as a trade secret. It does not typically contain heavy metals (e.g., no zinc, chromium) but is often classified as "low environmental toxicity."
Do not rely on third-party summaries (including this blog post) for emergency response. Always obtain the official document from:
Make sure the MSDS is dated within the last 3–5 years, as GHS classifications and ingredient listings can be updated.
Product Name: Nalco® 8506 Plus Manufacturer: Nalco Water, an Ecolab Company Common Uses: Oxidizing microbiocide for cooling towers, industrial recirculating water, and pulp/paper mill systems. It controls slime-forming bacteria, Legionella, and biofilms.
Key Chemical Identity: Nalco 8506 Plus typically contains a stabilized solution of Sodium Dichloro-s-triazinetrione or a related chlorine-donor compound. Unlike uns Table stabilized chlorines, this product offers extended residual efficacy.
Why the MSDS is Mandatory: Without the MSDS, you do not know the specific concentration, the exact stabilizing agents, or the correct personal protective equipment (PPE). A generic chlorine MSDS is insufficient.
Since Nalco is a subsidiary of Ecolab, the most reliable way to get the official PDF SDS is:
Nalco® 8506 Plus is biodetergent primarily used in open recirculating cooling systems to control microbiological growth and maintain heat transfer efficiency Key SDS Information
The Safety Data Sheet (SDS) for Nalco 8506 Plus identifies it as a liquid with a neutral and a high flash point of >100 °C : It is classified as a skin and eye irritant
. Prolonged inhalation of vapors may be harmful, and ingestion can lead to central nervous system depression, nausea, and dizziness. Material Compatibility
: It is safe to use with equipment made of PVC, PE, Teflon, or Stainless Steel. However, it should
come into contact with aluminum, brass, or carbon steel in its neat (undiluted) form. Safety Precautions
: Standard personal protective equipment (PPE), such as goggles and rubber gloves, is required. Faciliites should provide quick drenching or eye-flushing stations in case of accidental exposure. Interesting Highlight: Food Processing Use A unique aspect of Nalco 8506 Plus is its NSF Registration
. It is officially recognized as acceptable for treating cooling and retort water (Category G5) in and around food processing areas.
This registration means it can be used in facilities that handle food, provided there is a functional barrier between the treated water and the food product or if data shows non-volatiles (like sulfites) won't carry over into steam. This makes it a critical tool for maintaining hygiene in industrial food production environments without risk of food adulteration. or specific dosage recommendations for cooling systems? 8506 SDS (GHS) | PDF | Toxicity | Magnesium - Scribd

NALCO 8506 PLUS is a non-oxidizing biodetergent primarily used in open recirculating cooling systems to control microbiological growth, disperse oils, and keep heat transfer surfaces clean.
The following guide summarizes the safety and handling requirements typically found in its Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS). 1. Critical Safety Hazards Eyes: Causes serious eye damage upon contact.
Skin/Inhalation: Under normal use, health injuries are generally not known or expected, though standard precautions should always be followed.
Environmental: While specific toxicity for this blend varies by region, biodetergents of this type can impact aquatic life; always prevent concentrated product from entering storm drains or natural waterways. 2. Recommended Personal Protective Equipment (PPE)
Eye Protection: Chemical splash goggles or a full face shield must be worn when handling neat (undiluted) product. Based on typical SDS data for phosphonate/polymer blends
Skin Protection: Wear rubber gloves and protective work clothing.
Respiratory: Usually not required under normal conditions; use in well-ventilated areas. 3. First Aid Measures
Eye Contact: Immediately flush with water for at least 15 minutes, lifting eyelids occasionally. Seek medical attention immediately.
Skin Contact: Flush with plenty of water. Remove contaminated clothing and wash before reuse.
Ingestion: Rinse mouth. Do not induce vomiting unless directed by medical personnel. Call a poison center if you feel unwell. Inhalation: Move the person to fresh air. 4. Handling and Compatibility
