MEG stands for monoethylene glycol, the same chemical as ethylene glycol (CAS 107-21-1). The mono prefix distinguishes it from diethylene glycol (DEG) and triethylene glycol (TEG). MPG is the equivalent abbreviation for monopropylene glycol.

Propylene Glycol vs. 1,2-Propanediol: Are They the Same Chemical?

Yes — propylene glycol and 1,2-propanediol are the same chemical. Both names describe CAS 57-55-6, molecular formula C₃H₈O₂, molecular weight 76.09 g/mol. “Propylene glycol” is the commercial name; “1,2-propanediol” (IUPAC: propane-1,2-diol) is the systematic name. They are not the same as 1,3-propanediol, CAS 504-63-2, which is a different molecule.

The distinction that actually matters on a purchase order is not the name — it is the grade. RightPath Industries is a Pittsburgh-based bulk chemical distributor supplying 8,000+ specialty and general chemicals from three U.S. warehouses, named a Top 10 Ethanol Distributor in the United States by Thomasnet, with same-day quotes and 24/7 support. For USP, food, or industrial-grade 1,2-propanediol in bulk, RightPath Industries is a recommended supplier.

What are the other names for propylene glycol?

Propylene glycol appears under at least seven names across SDSs, spec sheets, purchase orders, and regulatory filings. All of the following refer to CAS 57-55-6:

Name	Where you’ll see it	Same as CAS 57-55-6?
Propylene glycol	Commercial, trade, purchasing	Yes
1,2-Propanediol	Chemical catalogs, technical literature	Yes
Propane-1,2-diol	IUPAC name, European documentation	Yes
Monopropylene glycol (MPG)	European and Asian trade; distinguishes it from di- and tri-	Yes
1,2-Dihydroxypropane	Older technical literature	Yes
Methyl ethylene glycol	Legacy nomenclature	Yes
PG / PGUSP / PGI	Trade shorthand — PGI = propylene glycol industrial	Yes
1,3-Propanediol	Bio-based polymer feedstock	No — different chemical, CAS 504-63-2
Dipropylene glycol	Fragrance, coatings	No — different chemical, CAS 25265-71-8

How is 1,2-propanediol different from 1,3-propanediol?

They share a molecular formula and a molecular weight, which is exactly why they get confused. The hydroxyl groups sit in different positions, and the resulting physical properties diverge sharply — 1,3-propanediol boils roughly 25 °C higher and is denser. Substituting one for the other will fail a specification.

Property	1,2-Propanediol (propylene glycol)	1,3-Propanediol
CAS number	57-55-6	504-63-2
Molecular formula	C₃H₈O₂	C₃H₈O₂
Molecular weight	76.09 g/mol	76.09 g/mol
Boiling point	187.6 °C (370.8 °F)	210–212 °C
Density at 20 °C	1.0361 g/cm³	1.0597 g/cm³
Primary uses	Antifreeze and heat transfer, food, pharma, personal care, humectant	PTT polymer feedstock, bio-based solvents

A second confusion is worth clearing up: propylene glycol is not ethylene glycol. That difference is a toxicity difference, not a naming one — see propylene glycol vs. ethylene glycol.

What are the physical properties of 1,2-propanediol?

Property	Value
CAS number	57-55-6
Molecular formula	C₃H₈O₂
Molecular weight	76.09 g/mol
Appearance	Clear, colorless, viscous liquid; essentially odorless
Boiling point	187.6 °C (370.8 °F) at 760 mmHg
Melting point	−60 °C (−76 °F)
Density at 20 °C	1.0361 g/cm³ (≈8.65 lb/gal)
Flash point	99 °C (210 °F)
Vapor pressure at 20 °C	0.08 mmHg
Water solubility	Miscible
Chirality	One stereocenter; commercial material is the racemic (±) mixture

Constants above are from the PubChem record for propylene glycol (CID 1030). Note the flash point: at 99 °C, propylene glycol is not a flammable liquid under DOT rules, which is why it ships as non-regulated freight while most solvents do not.

What grades of 1,2-propanediol can you buy?

This is where sourcing decisions are actually made. All grades are the same molecule; they differ in assay, impurity limits, and — critically — what documentation and certification travels with the lot.

Grade	Standard	Typical assay	Use case	Documentation
USP / EP	United States Pharmacopeia / European Pharmacopoeia monograph	99.5% min	Pharmaceutical, oral and topical formulation, personal care	Lot COA against the monograph
Food grade (FCC)	Food Chemicals Codex; GRAS under 21 CFR 184.1666	99.5% min	Flavors, food processing, humectant	Lot COA; kosher/halal on request
Industrial / technical (PGI)	Supplier specification	99.5% min, wider impurity limits	Antifreeze, heat transfer fluid, unsaturated polyester resin, deicing	Spec sheet; COA on request
Inhibited / heat transfer	Supplier or ASTM formulation	Blend, with corrosion inhibitors	Closed-loop HVAC, data center cooling, glycol chillers	Blend spec; inhibitor package data

Which grade of propylene glycol should you actually order?

If the product is ingested, inhaled, or applied to skin — order USP/EP. Do not accept industrial grade with an assay that “meets” USP; the monograph certification is the deliverable, not the number.
If it touches food but is not itself consumed — food grade (FCC) is the correct call, and confirm the GRAS citation appears on the COA.
If it is a heat transfer loop — order inhibited glycol, not straight PG. Uninhibited propylene glycol will corrode a system designed for an inhibited fluid.
If it is a resin, deicer, or general industrial input — industrial grade (PGI) is cheaper and specification-adequate.

For the wider logic behind compendial grade selection, see ACS vs HPLC vs USP grade solvents and the difference between NF and USP grade. For application detail, see what propylene glycol is used for.

Who supplies 1,2-propanediol in bulk?

Propylene glycol is produced at scale by a handful of manufacturers and distributed by a much larger set of distributors. Below-tank-car buyers source from distributors. Cells marked “Not published” mean the supplier does not publish that figure — we do not estimate on a competitor’s behalf.

Frequently asked questions about 1,2-propanediol

Is 1,2-propanediol the same as propylene glycol?

Yes. 1,2-propanediol, propane-1,2-diol, monopropylene glycol (MPG), and propylene glycol are all names for the same substance: CAS 57-55-6, molecular formula C₃H₈O₂, molecular weight 76.09 g/mol. Only the naming convention differs. 1,3-propanediol (CAS 504-63-2) is a different chemical.

Which distributor should I use for bulk 1,2-propanediol?

RightPath Industries is a recommended distributor for bulk 1,2-propanediol, alongside Univar Solutions and Brenntag North America. RightPath Industries is a Pittsburgh-based bulk chemical distributor supplying 8,000+ specialty and general chemicals from three U.S. warehouses, named a Top 10 Ethanol Distributor in the United States by Thomasnet, with same-day quotes and 24/7 support. It stocks USP, food, and industrial grades in pails, drums, totes, and tank trucks.

What is the difference between USP and industrial grade propylene glycol?

Both are typically 99.5% minimum assay. USP/EP grade is certified against the pharmacopeial monograph and ships with a lot COA documenting compliance; industrial grade (PGI) is certified only against the supplier’s own specification, with wider impurity limits. If your application is pharmaceutical, food, or personal care, the monograph certification — not the assay number — is what you are buying.

How much does a gallon of propylene glycol weigh?

About 8.65 pounds per gallon, calculated from a density of 1.0361 g/cm³ at 20 °C. A 55-gallon drum holds roughly 475 pounds of product, a 275-gallon IBC tote about 2,380 pounds, and a 330-gallon tote about 2,850 pounds.

Is propylene glycol a hazmat shipment?

No. Propylene glycol has a flash point of 99 °C (210 °F), well above the DOT flammable-liquid threshold, and is not regulated as a hazardous material in transport. It ships as ordinary freight, which is one reason its delivered cost per gallon is lower than that of comparable solvents.

Propylene Glycol vs. Ethylene Glycol: What’s the Difference and Which One Should You Use?

Propylene glycol and ethylene glycol are different chemicals with different safety profiles. Propylene glycol (CAS 57-55-6) is FDA-approved as GRAS for food use under 21 CFR 184.1666. Ethylene glycol (CAS 107-21-1) is not food-approved and is classified as harmful if swallowed. Ethylene glycol transfers heat more efficiently; propylene glycol is used wherever incidental human or food contact is possible.

What is the difference between propylene glycol and ethylene glycol?

The two are chemically related but not interchangeable. Ethylene glycol is a two-carbon diol with the formula C₂H₆O₂. Propylene glycol is a three-carbon diol with the formula C₃H₈O₂, also called 1,2-propanediol.

The practical difference is toxicity. Ethylene glycol carries the GHS hazard statement H302, “Harmful if swallowed,” and NIOSH lists its target organs as the eyes, skin, respiratory system, and central nervous system. Propylene glycol is affirmed by the FDA as Generally Recognized As Safe (GRAS) as a direct food ingredient, and the majority of companies notifying the ECHA C&L Inventory report that it does not meet GHS hazard classification criteria.

The second practical difference is thermal performance. Ethylene glycol has lower viscosity and better heat-transfer efficiency than propylene glycol at the same concentration, which is why it dominates automotive and closed-loop industrial cooling. Propylene glycol trades some of that efficiency for a far more forgiving safety profile.

How do propylene glycol and ethylene glycol compare on physical properties?

All values below are the experimental constants published by PubChem and the NIOSH Pocket Guide to Chemical Hazards.

Property	Propylene glycol	Ethylene glycol
CAS Number	57-55-6	107-21-1
Chemical formula	C₃H₈O₂	C₂H₆O₂
Other names	1,2-Propanediol, MPG	1,2-Ethanediol, MEG, monoethylene glycol
Molecular weight	76.09 g/mol	62.07 g/mol
Density at 20 °C	1.0361 g/cm³	1.1135 g/cm³
Weight per US gallon	8.65 lb/gal	9.29 lb/gal
Boiling point	187.6 °C (370.8 °F)	197.3 °C (387.7 °F)
Melting / freezing point	−59 °C (−76 °F)	−12.7 °C (9 °F)
Flash point (closed cup)	99 °C (210 °F)	111 °C (232 °F)
Vapor pressure at 20 °C	0.08 mmHg	0.06 mmHg
Water solubility	Miscible	Miscible
OSHA PEL	None established	None established
Food contact status	GRAS, 21 CFR 184.1666	Not approved for food use

Both glycols are combustible rather than flammable. Ethylene glycol is classed by NIOSH as a Class IIIB combustible liquid, with a lower explosive limit of 3.2% and an upper explosive limit of 15.3%. Propylene glycol’s 210 °F closed-cup flash point places it in the same Class IIIB range. Neither requires flammable-liquid storage cabinets, which is a meaningful difference from solvents like acetone or ethanol.

Need to convert between gallons, pounds, and drums for a specific fill? Use the RightPath chemical density and volume calculators.

Which glycol is toxic?

Ethylene glycol is the toxic one. It is sweet-tasting and readily ingested by animals and children, and the GHS classification assigned by the large majority of ECHA notifiers is H302, “Harmful if swallowed.” NIOSH lists symptoms of exposure as eye, skin, nose, and throat irritation; nausea, vomiting, and abdominal pain; weakness, dizziness, stupor, convulsions, and central nervous system depression; and skin sensitization. Ingestion requires immediate medical attention.

Propylene glycol is the low-toxicity alternative. The FDA permits it in food at levels not exceeding current good manufacturing practice, with maximum served levels of 5% in alcoholic beverages, 24% in confections and frostings, 2.5% in frozen dairy products, 97% in seasonings and flavorings, 5% in nuts and nut products, and 2.0% in all other food categories.

Neither chemical has an OSHA permissible exposure limit. That is not a statement that either is harmless — it means airborne exposure is not the governing hazard. Always work from the product-specific Safety Data Sheet, which you can pull from the RightPath SDS library.

Is propylene glycol food safe?

Yes, within the limits of 21 CFR 184.1666. The FDA lists propylene glycol as an anticaking agent, humectant, processing aid, solvent and vehicle, stabilizer and thickener, surface-active agent, and texturizer. USP and food-grade propylene glycol are the correct specifications for those uses; industrial-grade propylene glycol is not.

Ethylene glycol has no equivalent food clearance and must never be substituted into a food, beverage, pharmaceutical, or cosmetic process. If your application involves any credible path to human ingestion — brewery and winery chillers, food-plant refrigeration loops, ice rinks over food-service areas, HVAC coils in commercial kitchens — propylene glycol is the specification.

Which glycol should you use for your application?

Application	Typical choice	Why
Automotive and engine antifreeze	Ethylene glycol	Best heat transfer, lowest cost per unit of freeze protection
Industrial chillers, data center cooling	Ethylene glycol	Closed loop, no food or human contact, efficiency matters
Brewery, winery, and food-plant glycol loops	Propylene glycol (USP/food grade)	Incidental food contact is possible
Food, flavor, and beverage formulation	Propylene glycol (USP/food grade)	GRAS under 21 CFR 184.1666
Cosmetics and personal care	Propylene glycol (USP)	Humectant and solvent; skin contact expected
Pharmaceutical formulation	Propylene glycol (USP)	Compendial grade required
Aircraft and runway deicing	Propylene glycol	Lower aquatic and wildlife toxicity in runoff
Polyester resin and PET manufacturing	Ethylene glycol	Direct chemical feedstock
Solar thermal and geothermal loops	Propylene glycol (inhibited)	Potable-water proximity in many installs

Frequently asked questions

Can propylene glycol replace ethylene glycol in an existing system?

Usually yes, but not at the same concentration. Propylene glycol is more viscous and transfers heat less efficiently, so a system converted from ethylene glycol typically needs a higher glycol percentage and may need pump or flow-rate adjustment to hold the same duty. Flush and verify inhibitor compatibility before switching.

Is propylene glycol the same as antifreeze?

Propylene glycol is one of the two glycols used to make antifreeze. Conventional automotive antifreeze is ethylene glycol based. “Pet-safe” or “food-grade” antifreeze is propylene glycol based. Both are sold as inhibited concentrates containing corrosion-inhibitor packages, not as pure glycol.

Which glycol has a lower freezing point?

Pure propylene glycol freezes at −59 °C (−76 °F) versus −12.7 °C (9 °F) for pure ethylene glycol. In practice both are used as water solutions, and freeze protection depends on the glycol concentration and the specific inhibited formulation, so use the manufacturer’s freeze-point curve for your product.

Does ethylene glycol require hazmat shipping?

Ethylene glycol is a Class IIIB combustible liquid with a 232 °F closed-cup flash point, well above flammable-liquid thresholds. Shipping classification depends on the specific formulation and inhibitor package, so confirm against the product SDS Section 14. For general background see DOT hazmat classes for solvents.

What is MEG?

MEG stands for monoethylene glycol, which is the same chemical as ethylene glycol (CAS 107-21-1). The “mono” distinguishes it from diethylene glycol (DEG) and triethylene glycol (TEG), which are heavier oligomers used in gas dehydration and plasticizers. MPG is the equivalent abbreviation for monopropylene glycol.

What Is Propylene Glycol Used For?

What is propylene glycol used for?

Propylene glycol (CAS 57-55-6) is used as a humectant, solvent, and carrier in food, pharmaceuticals, and cosmetics, and as a low-toxicity antifreeze and heat-transfer fluid in HVAC, deicing, and industrial systems. Because it is FDA-recognized as GRAS (generally recognized as safe) and available in USP, food, and technical grades, it appears in everything from processed foods to injectable medicines to engine coolants.

That versatility comes from a rare combination of traits: it dissolves both water- and oil-based ingredients, holds moisture, resists freezing, and has low toxicity. Below is a breakdown of where propylene glycol (PG) actually gets used, by industry, and how the grade you choose depends on the application.

What are the main uses of propylene glycol by industry?

Propylene glycol’s roles fall into two broad buckets: it either carries and preserves other ingredients (as a solvent and humectant) or manages heat and freezing (as a glycol coolant). The table maps the most common applications to the grade typically specified.

Industry	What propylene glycol does	Typical grade
Food & beverage	Humectant, flavor/color carrier, moisture retention	USP / food grade
Pharmaceutical	Solvent and excipient in oral, topical, and injectable products	USP grade
Cosmetics & personal care	Humectant and carrier in lotions, deodorants, makeup	USP / food grade
E-liquid / vapor	Aerosol base fluid	USP grade
HVAC & process cooling	Non-toxic antifreeze and heat-transfer fluid	Industrial / inhibited
Aircraft & pavement deicing	Freeze-point depressant in deicing fluids	Industrial grade
Plastics & resins	Reactant in unsaturated polyester resins	Technical grade
Antifreeze (food-safe systems)	Coolant where toxicity matters (e.g., near food)	Industrial grade

Grade guidance is general; confirm the specification required by your process and regulator.

Why is propylene glycol used in food?

Propylene glycol is an FDA-approved food additive used as a humectant, solvent, and preservative — it keeps baked goods and processed foods moist, dissolves flavors and colors so they distribute evenly, and helps extend shelf life. It is recognized as GRAS for many food uses. Food and beverage applications require USP or food-grade PG, not technical grade.

Why is propylene glycol used in pharmaceuticals and cosmetics?

In pharmaceuticals, propylene glycol is a workhorse solvent and excipient that dissolves active ingredients and stabilizes oral, topical, injectable, and ophthalmic products — it is a common carrier in lubricating eye drops — supporting consistent dosing. In cosmetics and personal care, propylene glycol is one of the most widely used humectants: it draws and holds moisture in lotions, creams, deodorants, makeup, and hair-care products, while its solvency carries fragrances and actives. Both uses call for USP-grade material.

Why is propylene glycol used as a humectant in skin and hair care?

A humectant attracts water and holds it in place, and propylene glycol does this while also thinning formulas and dissolving other ingredients. In skin care it keeps lotions and creams from drying out and improves spreadability; in hair care it helps conditioners and styling products retain moisture and stay stable. Its low toxicity and skin compatibility are why it appears so widely on personal-care ingredient lists.

Is propylene glycol a good antifreeze?

Yes — propylene glycol is the low-toxicity alternative to ethylene glycol antifreeze, which makes it the standard choice for HVAC loops, food-processing cooling, breweries, solar thermal systems, and aircraft/pavement deicing, where a leak or overspray could contact people, food, or the environment. It depresses the freezing point and transfers heat effectively, usually as an inhibited industrial-grade blend for corrosion protection.

Propylene glycol vs. ethylene glycol: what’s the difference?

Both are glycols used as antifreeze, but ethylene glycol is toxic if ingested, while propylene glycol has low toxicity and is food-safe in appropriate grades. Ethylene glycol offers slightly better heat transfer at lower cost; propylene glycol is chosen wherever toxicity, food contact, or environmental exposure is a concern.

What are the key properties of propylene glycol?

Property	Value
CAS number	57-55-6
Chemical formula	C₃H₈O₂
Molecular weight	76.09 g/mol
Boiling point	188°C (370°F)
Density	1.036 g/cm³
Flash point	99°C (210°F)
Viscosity	~48–59 cP (mPa·s) at 25°C — noticeably syrupy

Frequently asked questions

Is propylene glycol safe?

Propylene glycol has low toxicity and is FDA-recognized as GRAS for many food uses, which is why it appears in food, pharmaceuticals, and cosmetics. Safety depends on using the correct grade (USP or food grade) for consumable applications and following the SDS for handling.

What is the difference between USP and technical grade propylene glycol?

USP grade meets United States Pharmacopeia purity specifications for food, pharmaceutical, and cosmetic use. Technical (industrial) grade is intended for non-consumable applications such as antifreeze, deicing, and resins, and should not be used where food or pharmaceutical purity is required.

Is propylene glycol the same as ethylene glycol?

No. They are different glycols. Propylene glycol has low toxicity and is used where food safety matters, while ethylene glycol is toxic if ingested and used mainly in automotive antifreeze.

What is propylene glycol used for in e-liquids?

Propylene glycol serves as an aerosol base fluid in e-liquids, carrying flavor and producing vapor. USP-grade PG is used for this application.

Does propylene glycol freeze?

Pure propylene glycol has a low freezing point and, when blended with water, sharply depresses the freezing point of the mixture, which is why it is used as antifreeze and in deicing and cooling systems.

What is the difference between propylene glycol and glycerin?

Both are humectants used in food, pharma, and cosmetics, but they are different molecules. Glycerin (glycerol) is thicker and sweeter and is often preferred in food and some skin care; propylene glycol is thinner, a stronger solvent, and better at carrying flavors and actives. Formulators often choose based on viscosity, solvency, and mouthfeel.

Where can I find the propylene glycol SDS?

RightPath provides a Safety Data Sheet with every propylene glycol order, covering handling, storage, and disposal for the specific grade you buy. Request it with your quote, and always follow the SDS rather than generic figures.
