Propylene Glycol Versus Ethlyene Glycol

Glycol an organic compound belongs to the alcohol family. One of the simplest members of the class is Ethylene Glycol which is one of the organic compounds being talked about in this blog, along with Propylene Glycol which is another member of this class that isn’t as simple as Ethylene Glycol.

What is Propylene Glycol?

For the simplest terms, Propylene Glycol is a liquid that has no color, no smell, and no taste and belongs in the chemical class of alcohol. Propylene alcohol serves the main purpose of absorbing water. People will commonly mistake Propylene glycol for Ethylene glycol, but the contrast is that Ethylene glycol is toxic. Propylene glycol is an additive product and serves many different purposes in a multitude of industries.

Some of these uses for Propylene Glycol include:

  • Food Industry Coolants
  • Deicing and antifreeze fluids
  • Non-ionic Detergents
  • Plasticizers
  • Hydraulic brake fluids
  • Solvent
  • Extractant
  • Humectant
  • Unsaturated Polyester Resins

What is Ethylene Glycol?

Slightly similar but different, Ethylene glycol is a synthetic liquid that also absorbs water. Ethylene glycol is odorless, colorless, and also in contrast has a sweet taste. As mentioned before, Ethylene glycol is toxic which makes it the biggest difference from Propylene glycol  besides having a taste, unlike the tasteless Propylene glycol. Ethylene glycol serves similar purposes in different industries but lacks some of the other uses and is limited in applications.

Some uses of Ethylene Glycol include:

  • Antifreeze and de-icing solutions
    • Auto
    • Aviation
    • Boating
  • Hydraulic brake fluid
  • Inks (used in)
    • Stamp pads
    • Ballpoint Pens
    • Print Shops


Propylene glycol and Ethylene glycol through their descriptions and definitions have many similarities, but the biggest difference that needs to be discussed is their levels of toxicity and Ethylene glycol being heavily toxic. The ATSDR classifies Ethylene glycol as a CNS depressant, a similar substance would be ethanol, classifying it as a hazardous material. Ethylene glycol if ingested affects kidney function and can affect the acid/base balance in the human body. Propylene glycol is not toxic compared to Ethylene glycol because it’s recognized as safe by the ATSDR for the pharmaceutical and food industries, and rarely results in toxic effects. In circumstances where there was a toxic effect, it was in strange circumstances. Though they both serve important purposes one is safer for human consumption than others.

Video Jet Printers

Video Jet Printers

What are Video Jet Printers?

In the printing world, there are so many emerging technologies ones we’ve used before, and many that are breaking barriers of what we know and can do. Recently, I did some research into VideoJet Printers and learned about who they provide for and what they can do for the printing industry. VideoJet’s industrial printers do a wide variety of regular printing to thermal transfers, and labeling systems. They even have a process where ink that isn’t used can be put back into the printer during the printing process.

Videojet Printers provide many different products. They are an OEM (original equipment manufacturer) and provide printers to lasers, to anything you can think of that prints something onto a product.

Industries Printers are used in are:

  • Food and Beverage
    • Candy
    • Beverages
    • Eggs
    • Fruits & Veggies
    • Meat
  • Pharmaceuticals & Beauty
    • Cosmetics
    • Pharmacy
    • Medical equipment
    • Tobacco
  • Industrial
    • Auto Industry
    • Aerospace
    • Chemicals
    • Construction
    • Electronics

Covering a wide range of industries these printers can cover so many different products and services. While we now know what industries these printers can be used for it’s also important to know what specific products it can be applied to.

Applications of VideoJet Printers:

  • Packaging
  • Lumber
  • Egg Cartons
  • Plastic Parts
  • Glass Bottles
  • Glass Containers
  • Shrink Wrap
  • Film & Foils
  • Aluminum Cans

While there are many more applications to list most are subcategories of the main ones listed above. If you are using printers like these, one of the biggest questions you can ask yourself is what do you clean these products with when you’re done, well that depends on what solvent you use.

Simply put if you use an ethanol based solvent, then you need an ethanol based cleaner to clean it. Whatever you put in you use something of the same family to treat and clean it. According to VideoJet, that is the most effective way to clean their products.

If you or someone you know has a VideoJet Printer that needs cleaner, and you need help matching a cleaner for your product, contact us here or if you already know what you need you can find a list of our cleaning solutions here.
