Frequently Asked Questions

Is E422 glycerine vegan?
E422 can be plant- or animal-derived. If the packaging states 'vegetable glycerine', 'plant-derived glycerol', or displays a certified vegan symbol, it is 100% vegan. Unspecified 'glycerine' in non-certified products may come from animal tallow.
What is vegetable glycerine made from?
Vegetable glycerine is produced by hydrolyzing plant-based triglycerides, typically extracted from palm, coconut, soybean, or canola oils under high pressure and temperature.
Is glycerine in toothpaste vegan?
Most mainstream toothpaste brands use glycerine to maintain moisture. Look for brands explicitly stating 'plant-based vegetable glycerine' or carrying cruelty-free vegan credentials.
