Who Buys This

Maintenance and facilities teams charging closed-loop cooling systems, industrial operators running glycol heat transfer circuits, and automotive and equipment shops that need a ready-to-use antifreeze/coolant blend. Lab and bench users buy the quart sizes for small-scale temperature control work.

Purity / Grade Guide

Laboratory grade, pre-diluted to a 50/50 ethylene glycol/water ratio — the standard balance of freeze protection and heat capacity, so you charge systems without on-site mixing. Review the technical data sheet to confirm it matches your process spec.

Pack Sizes

1 quart and 1 gallon sizes suit lab benches and maintenance top-ups; 5 and 15 gallon packages cover small systems; 55 gallon drums and 275–330 gallon totes serve production-scale cooling and heat transfer loops.

Small Packs: UPS Ground nationwide for pints, quarts, and gallons.

LTL / FTL: ABF, SEFL, Saia, XPO, and partner carriers for pails, drums, totes, and full truckloads.

Support: Email or call for freight options, hazardous-material routing, and lead-time confirmation.

Product Overview

Ethylene Glycol 50/50 is a pre-diluted, Laboratory grade blend of ethylene glycol (CAS 107-21-1) and water, sold ready to use as an antifreeze and coolant base and as a general-purpose heat transfer fluid. The 50/50 ratio is the workhorse concentration for temperature control: enough glycol for freeze protection, enough water for heat capacity. Buyers who order it from us include maintenance teams topping up closed-loop cooling systems, industrial operators running heat transfer circuits, and lab and facilities staff who want a consistent pre-mixed solution instead of blending concentrate on site.

We pack it across a wide range — from 1 quart bottles for bench and lab use up to 55 gallon drums, 275 gallon totes, and 330 gallon totes for production-scale systems. All listed sizes are offered to order.

Why This Concentration

A 50/50 mix is the standard trade-off point between freeze protection and thermal performance. Water carries heat better than glycol; glycol depresses the freezing point and raises the boiling point. At 50/50 you get a balanced fluid that serves most closed-loop cooling, antifreeze, and heat transfer duties without the handling step of diluting concentrate — no on-site water quality question, no mixing error, and a consistent density of 1.07 g/mL at 20 °C from container to container.

Pick the pre-mixed 50/50 when your system spec calls for a standard glycol/water charge and you want repeatability. If your process needs a different glycol ratio for deeper freeze protection, that is a different product spec — confirm your system's requirement against the technical data sheet before ordering.

Chemical Profile

Ethylene glycol is a clear, colorless, syrupy liquid; this product is the 50/50 aqueous solution, an odorless liquid with a density of 1.07 g/mL at 20 °C. Ethylene glycol is fully miscible in water — published solubility is greater than or equal to 100 mg/mL at 63.5 °F — and its vapor pressure is low: 0.06 mmHg at 68 °F, rising to 1 mmHg at 127.4 °F. That low volatility is why glycol loops hold their charge instead of flashing off. The active component is ethylene glycol, formula C2H6O2, molecular weight 62.07, CAS 107-21-1. One point every handler should know: the primary hazard of ethylene glycol is environmental. As a water-miscible liquid it penetrates soil readily and can reach groundwater and nearby streams, so any spill should be contained immediately.

Industrial Applications

These are the established industrial uses buyers order this solution for:

Antifreeze — automotive and equipment cooling. In cooling systems, the glycol fraction lowers the freezing point and raises the boiling point of the coolant charge, protecting blocks, pumps, and radiators through seasonal extremes.
Heat transfer fluid — industrial loops. In closed-loop process cooling and heating circuits, a 50/50 glycol/water charge moves heat between the process and the exchanger while resisting freeze damage during shutdowns.
Hydraulic fluid component. Glycol/water solutions serve in certain hydraulic systems where a water-based, lubricating fluid is specified.
De-icing. Glycol solutions are applied to surfaces to prevent and remove ice formation in winter operations.
Solvent duty. Ethylene glycol acts as a solvent and reaction medium in some chemical manufacturing processes.

In every case, verify fluid compatibility and concentration requirements against your equipment manufacturer's specification and our technical data sheet before charging a system.

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). Treat it accordingly: wear gloves and goggles, ventilate the work area, and never leave open containers where the sweet-tasting liquid could be mistaken for something drinkable.

Store in a cool, dry area out of direct sunlight, in compatible containers — HDPE and stainless steel are standard choices. Keep it away from strong oxidizing agents. Because a release threatens soil and groundwater, stage containers over secondary containment and keep absorbent on hand; limiting spread is the first response to any spill.

Hazmat & Shipping

Canonical transport status is not regulated. Review the current SDS and carrier requirements before shipment.

Documentation

A Safety Data Sheet ships with every order and is available in English, Spanish, French, and Japanese. A technical data sheet is available for spec review before you buy, and a lot-specific Certificate of Analysis is available with your shipment. If your receiving, EHS, or purchasing process needs any of these documents up front, ask and we will send them ahead of the order.
