There’s also a push towards using bio-based propylene glycol, derived from natural sources like vegetable oils, instead of the traditional method. This shift aligns with a global move towards more sustainable and natural ingredients.

For those concerned with dietary information beyond veganism, it’s worth noting that propylene glycol is gluten-free. Moreover, products containing it are often stored in tamper-evident containers and under cool conditions, away from direct sunlight, to maintain their premium quality USP.

The European Union and the EU & UK authorities have set guidelines for the acceptable daily intake of propylene glycol, ensuring it’s safe even when consumed in large amounts.

So, get ready to uncover the truth about propylene glycol. Is it a vegan, plant-based compound safe for the heart, and what is its toxicity source?

Is Propylene glycol plant-based?

Propylene glycol is a synthetic organic compound, and while it is not derived from animal sources, it is also not directly derived from plants in the way that one might consider fruits, vegetables, or grains “plant-based.” It is primarily produced through the hydration of propylene oxide, which is a petrochemical.

However, there is a distinction to be made:

  1. Traditional Propylene Glycol: This is derived from petrochemicals. It is not plant-based, derived directly from plants, but not animal-derived.
  2. Bio-based Propylene Glycol: This version is derived from plant sources, specifically from processing vegetable oils or certain types of biomass. So, in this context, one could consider bio-based propylene glycol plant-based.

When propylene glycol is used as a food additive, it serves as a solvent, humectant, and preservative. It’s found in various food products and is generally recognized as safe (GRAS) by many health authorities, including the U.S. Food and Drug Administration.

For individuals specifically looking for plant-based or natural ingredients in their foods, it’s essential to clarify the source of the propylene glycol. If it’s bio-based, then it aligns more closely with a plant-based paradigm. If it’s the traditional form, it’s still vegan (as it’s not animal-derived) but not directly plant-based.
