Health & Fire Hazard
Acute Toxicology
- LD₅₀ Oral (rat)
- Ethylene glycol 4,700 mg/kg (rat); human lethal dose about 1,400–1,600 mg/kg. ATE for this 42.6 wt% blend about 1,170 mg/kg (from the 500 mg/kg acute-toxicity estimate), the basis for H302.Adjudicated
- LD₅₀ Dermal (rabbit)
- > 10,600 mg/kg (ethylene glycol)Adjudicated
Acute toxicology values from SDS Section 11 or NIOSH RTECS.
Supplier Qualification Packet
One zipped download containing the TDS, SDS, latest lot COA (when available), and a fresh Letter of Continuing Guaranty for Ethylene Glycol 40/60. Every file included is SHA-256 hashed and listed in a manifest your QA team can audit.
Applications
Ready-to-use heat-transfer fluid and antifreeze for closed-loop cooling and heating systems, chillers and process equipment.Adjudicated
Restrictions on Use: Not for food, drug or cosmetic use, and not for potable-water systems. Harmful if swallowed and it tastes sweet: keep away from children and pets, and do not store in food or drink containers.
Storage & Handling
- Recommended Storage
- Keep closed in a cool place away from oxidizers. Protect from freezing below the rated freeze point. Store separately from food and drink.Adjudicated
- Handling Precautions
- Chemical-resistant gloves and splash goggles. Ethylene glycol grades are toxic by ingestion and must be kept away from food, drink and animals; propylene glycol grades are not. Avoid contact with hot surfaces and hot process equipment. Inhibitor packages deplete in service — monitor rather than top up blindly.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Strong oxidizing agents, strong acids and bases, aldehydes, alkali metals.Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
