This substance may be derived from animals.

When glycerin is derived from animals it is most commonly sourced from tallow. Tallow usually refers to fat sourced from beef and mutton but could it can also include fat from pigs and lards.

No matter how it is sourced, vegan or non-vegan, this ingredient is often named the same. To know if the product is free from animal biological parts, look for “vegetarian” or “vegan” stamps on the product or in the product description. In some cases you may even have to ask the manufacturer to know how the ingredient is sourced.

How is it used?

Glycerin can be found in all kinds of products and applications, and there are numerous derivatives containing this substance.

The nonprofit organization People for the Ethical Treatment of Animals (PETA) have found this substance in “cosmetics, foods, mouthwashes, chewing gum, toothpastes, soaps, ointments, medicines, lubricants, transmission and brake fluid, and plastics.”

It functions for example as a solvent, hygroscopic (can absorb or adsorb water from surrounding area), filler, humectant (holds and retains moisture) and lubricant in the different kind of products.

After water, glycerol is reportedly the most common ingredient found in cosmetics, according to the FDA’s Voluntary Cosmetic Reporting Program.
