Propylene Glycol USP/FCC is high-purity 1,2-propanediol (C₃H₈O₂, CAS 57-55-6), also called PG or monopropylene glycol. It meets United States Pharmacopeia (USP-NF) and Food Chemicals Codex (FCC) standards, with 99.5% minimum purity and 100% bio-based carbon. Level 7 Chemical supplies it in new plastic 55-gallon drums (474–480 lb net), by the single drum with 2- and 4-drum options, and larger orders quoted on request.
Propylene glycol is a clear, colorless, essentially odorless liquid that mixes completely with water. In foods it is used in confectionery, ice cream and baked and frozen goods, and it is widely used as a food-grade heat transfer fluid and safety antifreeze, a coupling agent, a food-grade lubricant and an ingredient in pharmaceutical and personal care products.

GHS Hazard Information
Not classified as hazardous
Propylene glycol USP is not classified for physical, health or environmental hazards and is not known to be a hazardous chemical under the OSHA Hazard Communication Standard (29 CFR 1910.1200). No hazard pictograms or signal word are required. It is not regulated as a hazardous material for DOT shipping.
The Safety Data Sheet notes it may be harmful if swallowed and enters airways. Good practice still applies — see the SDS for handling, PPE and first-aid details.
Which Propylene Glycol Do You Need?

Frequently Asked Questions
What is propylene glycol USP?
Propylene glycol USP (1,2-propanediol, CAS 57-55-6) is a clear, colorless, essentially odorless liquid that meets USP-NF and FCC standards. It is used in food, beverage, pharmaceutical and personal care products, and as a food-grade heat transfer fluid, antifreeze, coupling agent and lubricant.
Is this propylene glycol food grade?
Yes. This propylene glycol meets USP-NF and FCC (Food Chemicals Codex) standards, and the manufacturer's Certificate of Analysis lists it for excipient and food use. Check with us if you need other certifications.
What is the difference between USP and technical grade propylene glycol?
USP/FCC propylene glycol is made and tested for food, pharmaceutical and personal care use. Technical grade is for industrial uses such as heat transfer fluids, antifreeze and solvents where a food or pharmaceutical grade is not required.
Is the 5 gallon pail USP certified?
No. The 5 gallon pail is repackaged from USP-grade drums, but once repackaged it does not retain its USP / food certification. Buy the 55-gallon drum if you need certified USP/FCC propylene glycol.
Is this propylene glycol bio-based?
Yes. The manufacturer guarantees 100% minimum bio-based carbon content for this propylene glycol. Confirm with C of A when purchasing.
Can I get propylene glycol in a different grade or concentration?
Yes — contact Level 7 Chemical by phone at (855) 927-1777 or request a quote, and we'll let you know which other grades and strengths are available.
Is there a minimum order, and can I buy more than one drum?
There is no minimum order — you can buy a single 55-gallon drum. 2-drum and 4-drum options are also available, and larger orders are quoted on request.
Do you provide an SDS and Certificate of Analysis?
Yes. The Safety Data Sheet and a sample Certificate of Analysis can be downloaded on this page, and lot-specific COAs are available on request.
We quote multi-pallet, full-truckload and recurring orders. Call us or request a quote and we'll get back to you fast.
Prices, product availability and delivery timelines are subject to change without notice due to market conditions and factors beyond the control of Level 7 Chemical and our suppliers. See our Terms of Service.
