Is it vegan? Additives & E-numbers E422
Is glycerin vegan?
Quick answer: It depends. Glycerin (E422) can be made from plant oils, animal fat or petrochemicals; “vegetable glycerin” is vegan, but plain “glycerin” may not be.
Also called: glycerine, glycerol, E422, vegetable glycerin
The details
Glycerol is a sweet, syrupy liquid used as a humectant (to keep foods moist), a solvent for flavourings and a sweetener. It is a by-product of soap and biodiesel making and can come from vegetable oils, animal fats such as tallow, or synthesis.
The Vegetarian Resource Group notes that commercial glycerin is commonly animal-based or a blend, and that even kosher glycerin can be animal-based. In cosmetics, glycerin is very common and is usually plant-derived, but only the brand can confirm it.
