Here's a breakdown:
* Older Glues: These might have used animal-based ingredients like:
* Gelatin: Made from boiled animal collagen, used in some adhesives and glues.
* Hide glue: Made from animal hides and bones, used in woodworking and furniture making.
* Modern Glues: Most modern glues are made from synthetic polymers, resins, and other chemicals. These are considered vegan and don't contain any animal products.
If you're concerned about animal products in glue, check the label for ingredients. Look for terms like "animal glue" or "hide glue" as these indicate an animal-based product. If the ingredients are listed as "synthetic" or "polymer-based," the glue is likely vegan.
