Product Overview
Ethylene Glycol 60/40 is a technical grade blend of ethylene glycol (C2H6O2, CAS 107-21-1) and water at a 60/40 ratio. It is a clear, colorless, odorless, syrupy liquid sold ready to use as an antifreeze, industrial cooling fluid, and heat transfer medium. Because the glycol is already blended with water, it goes into a jacketed vessel, closed cooling loop, or engine cooling system without on-site dilution.
This page serves the buyers who actually order it: maintenance leads keeping process chillers and heat transfer loops running, fleet and equipment shops charging cooling systems, and plant operators who need drum or tote quantities of a working-strength glycol fluid rather than concentrate.
Why This Concentration
A 60/40 ethylene glycol/water blend sits on the glycol-rich side of the common coolant range. More glycol in the blend means deeper freeze protection than a leaner mix, at the cost of higher viscosity and lower specific heat than plain water — the standard trade-off in any glycol heat transfer system. Buyers pick 60/40 when their system needs strong low-temperature protection and they want the blend ratio controlled at the point of packaging instead of mixed at the plant.
Choosing pre-blended fluid also removes a failure mode we see often in the field: dilution drift. When operators cut concentrate with untreated tap water at the machine, blend ratios wander from fill to fill. A packaged 60/40 arrives at the same ratio in the quart as in the 330 gallon tote.
The Technical grade descriptor signals an industrial-process product. It is the designation buyers request for cooling loops, antifreeze service, and general plant use where a laboratory or pharmacopeia designation is not part of the purchase specification.
Chemical Profile
Ethylene Glycol 60/40 is a clear, colorless, syrupy liquid with no odor — a spill or leak will not announce itself by smell, so rely on inspection rather than your nose. The 60/40 blend has a density of 1.08 g/mL at 20 °C, noticeably heavier than water; a full 55 gallon drum reflects that extra mass, and rigging should account for it. Ethylene glycol is highly water-miscible, with solubility of 100 mg/mL or greater at 63.5 °F, which is why it blends into cooling water in any proportion. Vapor pressure is low — 0.06 mmHg at 68 °F, rising to 1 mmHg at 127.4 °F — so it evaporates slowly and stays where you put it. The glycol component is ethylene glycol, formula C2H6O2, molecular weight 62.07, CAS 107-21-1.
Industrial Applications
-
Antifreeze. In automotive and equipment cooling systems, ethylene glycol lowers the freezing point of the coolant so blocks, radiators, and lines survive winter shutdowns and cold starts.
-
Heat transfer fluid. In closed industrial loops — chillers, jacketed reactors, HVAC circuits — the glycol/water blend carries heat between the process and the exchanger while resisting freezing at the cold end of the loop.
-
De-icing. Glycol fluids are applied to surfaces in aviation and winter operations to prevent ice formation.
-
Process solvent. Chemical manufacturers use ethylene glycol as a solvent medium in synthesis and formulation work where a water-miscible, low-volatility liquid is needed.
Handling & Storage
This product carries the signal word Warning, with hazard statements H302, harmful if swallowed, and H373, may cause damage to organs (kidneys) through prolonged or repeated exposure (per the product's GHS classification). Ingestion is the hazard that matters most in practice: never transfer glycol into unmarked drink-style containers, and keep transfer stations away from break areas. Wear gloves and goggles when handling, and ventilate enclosed transfer areas.
Store in a cool, dry area out of direct sunlight, in compatible containers such as HDPE or stainless steel, and away from strong oxidizing agents. The liquid is stable in normal warehouse storage. Treat spills as an environmental event, not just a slip hazard: ethylene glycol penetrates soil readily and can reach groundwater and nearby streams, so contain and recover a release immediately rather than washing it to a drain.
Hazmat & Shipping
Ethylene Glycol 60/40 is not classified as a hazardous material for transport — it carries no UN number, hazard class, or packing group assignment (per 49 CFR 172.101). It ships as standard freight from our warehouse in Taylor, Texas. That transport classification describes the regulated status of the material itself; confirm service details and any receiving requirements with your carrier and site as you normally would.
Documentation
A Safety Data Sheet accompanies every order, available in English, Spanish, French, and Japanese. A Technical Data Sheet is available for engineering and procurement review, and a lot-specific Certificate of Analysis is available on request, so your records can tie the fluid in your loop back to the lot that filled it.
Why Buy from Alliance Chemical
We package Ethylene Glycol 60/40 across the full industrial range — quarts and single gallons for bench work and top-offs, 5 and 15 gallon carboys and drums for standing maintenance stock, 55 gallon drums for production loops, and 275 and 330 gallon totes for bulk charging — all offered to order from one supplier, with SDS, TDS, and COA documentation behind every lot. Alliance Chemical has operated since 1998 and has served more than 50,000 customers from our Taylor, Texas warehouse. Shipping and handling guidance on this page is reviewed by Andre Taki, DOT Hazmat Specialist.
