I never learned how glue was made as a child, but I always had the notion that it came from animals like horses, which I must have heard somewhere.
Fast forward to now, and I really wanted to know the answer.
So, I looked up how glue is made to find out if it’s vegan.
Good News: Most Glues Are Vegan
It turns out that most glues used to be mainly made of animal products (mainly from horses, but also cows).
Collagen from bones and tendons was boiled to form a protein solution that functioned as glue.
But nowadays, most glues are synthetic.
Unfortunately, there’s no ingredients label on most glues (apparently you’re not supposed to eat it), so you’ll have to contact specific manufacturers for clarification.
What I can tell you is that these brands only sell vegan friendly glues (all synthetic, no animal testing):
- Elmer’s glue
- Gorilla glue
- UHU glue
Most basic glue sticks and hot glue sticks are vegan, but again, contact the manufacturer if you’re not sure.
It’s actually pretty hard to find a glue that contains animal products these days.
They are mainly used for things like:
- Fine woodworking
- Glass art
- Antique work
- Repairing string instruments (e.g. violin, etc.)
The most common type of glue that is still made from animal ingredients is hide glue.
Some other glues contain isinglass, which is derived from animal bladders.
Hopefully all glue will be vegan one day. For now, just check specific brands if you need to buy or use a glue.
