Why
Roughly 2,500 silkworms die per pound of silk. 'Peace silk' lets the moth emerge first, but the moths are still bred, and many vegans avoid it too.
What to check on the label
- The ingredient list on your own pack — Silk recipes differ by country and change over time
- Milk, whey, casein, lactose, egg, honey, gelatin, carmine (E120) and shellac (E904) in the list
- "May contain milk" is an allergen cross-contamination note, not an ingredient — most vegans still buy it

Questions people ask
Is Silk certified vegan?
Certification is separate from the recipe. Many products with no animal ingredients carry no vegan mark because the maker will not rule out shared production lines. Check the pack for a registered vegan trademark, and treat the ingredient list as the primary evidence.
Does the answer change between countries?
Often, yes. The same brand name can use different fats, emulsifiers, colours or whey depending on the plant that made it, so always read the local label rather than an answer written for another market.
