Does vegetable glycerin go bad?

Vegetable glycerin is a versatile product used in multiple industries, from pharmaceuticals to cosmetics-making. It’s a liquid that can be ingested or applied directly to skin, but does it ever expire and, if so, how long does it last?

What is Vegetable Glycerin?

Vegetable glycerin (sometimes known as glycerol) is a natural product, often derived from plants such as soy or coconut. It’s a colorless and odorless liquid with a thick consistency, and is often used as a substitute for oils and fats in cooking. It’s also used to make hand sanitizer, soaps, lotions, and many other household items.

Does Vegatable Glycerin go Bad?

In general, vegetable glycerin does not go bad and can last for years when stored properly. Keep in mind, however, that it can become contaminated if it comes into contact with other substances, so always strive to keep it sealed and away from moisture and air.

To extend the shelf-life of your vegetable glycerin, here are some tips:

  • Store in a cool, dry place: Ideal temperatures range between 10-21 degrees Celsius (50-70 degrees Fahrenheit). Avoid storing near direct sunlight, moisture, or heat sources to ensure it lasts as long as possible.
  • Keep it tightly sealed: Make sure you store it in an airtight container and seal it tightly after each use. This helps keep out any contaminants and prevents the glycerin from evaporating.
  • Check the label: Check the expiration date on your container (if any) to be sure it hasn’t passed. If it’s been open for longer than a month, it’s best to discard it.

What if Vegatable Glycerin is Contaminated?

If at any point your vegetable glycerin becomes discolored, develops a strange smell, or seems off in any way, it’s likely that it’s become contaminated and should be discarded.


In short, vegetable glycerin is a versatile product often used in cooking, cosmetics, and pharmaceuticals. When stored properly, it can last for years without going bad. However, it’s best to keep an eye on the expiration date and always discard it if it’s contaminated.
