About Ethylene Glycol

Buy ethylene glycol (CAS 107-21-1) from Alliance Chemical in inhibited concentrates, premixed coolants, and high-purity options. Ethylene glycol is a heat-transfer fluid and chemical intermediate used in HVAC loops, process cooling, antifreeze, data-center cooling support, and selected electronics workflows.

Products In This Collection

This collection includes 50/50 and 60/40 premixed ethylene glycol formulations, 100% inhibited ethylene glycol, and semiconductor-grade ethylene glycol where available. Inhibited products help control corrosion, scale, and fouling in compatible closed-loop systems.

Common Applications

  • HVAC and process cooling: Inhibited ethylene glycol is used in closed-loop chillers, hydronic systems, and process heat-transfer circuits that need freeze and corrosion protection.
  • Antifreeze and freeze protection: Ethylene glycol depresses freezing point and raises boiling point in compatible systems when concentration and inhibitor chemistry are correct.
  • Data center and electronics cooling: Glycol blends support engineered cooling loops where thermal performance, water quality, and materials compatibility are controlled.
  • Semiconductor and specialty use: High-purity ethylene glycol can support validated electronics and specialty chemical workflows where impurity profile matters.

Grade & Selection Notes

Choose premixed 50/50 or 60/40 when your system specification calls for a ready-to-use blend. Choose 100% inhibited ethylene glycol when dilution will be controlled on site. Choose semiconductor grade only where high-purity specifications are required and approved.

Safety & Handling

Ethylene glycol is harmful if swallowed and must be kept away from food, drink, children, pets, and uncontrolled drains. Use PPE, avoid mist or aerosol exposure, clean spills promptly, and dispose of spent glycol according to local requirements. Review the Safety Data Sheets before use and follow your site-specific handling procedure.

Why Buy From Alliance Chemical

Most in-stock ethylene glycol products ship from Taylor, Texas with SDS support and lot documentation where applicable. Bulk orders can be quoted for facility and process-cooling requirements.

Frequently Asked Questions

Where can I buy ethylene glycol?
Right here. Alliance stocks ethylene glycol from 30% blends to 100% in inhibited, technical, ACS and semiconductor grades, in 1 quart, 1 gallon, 5, 15 and 55 gallon drums and 275 and 330 gallon totes. Ships from Texas in 1 to 2 business days with the SDS on every product page.
Inhibited or uninhibited: which ethylene glycol do I need?
Inhibited for closed-loop heat transfer, chillers and HVAC, where the inhibitor package protects metal. Uninhibited technical grade when you add your own treatment or need the raw glycol. Premixed 30% to 60% blends are ready to pour. ACS and semiconductor grades for labs and fabs.
Can I buy ethylene glycol in bulk?
Yes. 55-gallon drums and 275-gallon and 330-gallon totes ship on a pallet by LTL freight. For multi-drum or recurring supply, use the quote form on any product page and we price it with freight.
Who can buy ethylene glycol?
Anyone. Alliance sells ethylene glycol, 30% to 100% in inhibited, technical, ACS, and semiconductor grades, online to businesses and individuals, quart through tote. It is not a DEA listed chemical and no federal rule restricts who may buy it, so no license, permit, or purchase record is required. It is toxic if swallowed, follow the SDS.
How is ethylene glycol shipped?
Ethylene glycol is not a DOT hazardous material in any size sold: it has no hazard class, and its 5,000 lb reportable quantity is never reached in one package, even a 330-gallon tote. Quarts, gallons, and pails ship as ordinary UPS Ground parcels, drums and totes by LTL freight.
What is ethylene glycol used for?
Ethylene glycol is used in antifreeze, HVAC loops, process cooling, heat-transfer fluids, chemical manufacturing, and selected high-purity applications.
Should I choose premixed or 100% ethylene glycol?
Use premixed products when your system calls for a ready-to-use blend. Use 100% inhibited ethylene glycol when dilution, water quality, and final concentration will be controlled on site.
What does inhibited ethylene glycol mean?
Inhibited ethylene glycol contains additives designed to help control corrosion, scale, and fouling in compatible closed-loop systems.
Is ethylene glycol the same as propylene glycol?
No. Both are glycols used in heat-transfer applications, but they differ in toxicity profile, regulatory suitability, and system requirements.
Can ethylene glycol be used in food-adjacent systems?
Do not use ethylene glycol where incidental food or beverage contact is possible unless the system design and applicable regulations explicitly allow it. Propylene glycol is often evaluated for those applications.
