Is carmine vegan?

Carmine is made from cochineal insects. Cochineal extract is the broader preparation, carmine is the refined form, and both come from the same source.

So the answer is straightforwardly no, and the useful part of this page is everything after that.

Where you will and will not see the word

On US food labels it must be named. Under 21 CFR 73.100, products containing cochineal extract or carmine have to declare it by its common name in the ingredient list. Colour additives can often be grouped under a collective term; this one cannot. That rule exists because of documented allergic reactions, and it happens to help anyone avoiding animal ingredients as a side effect.

On cosmetics it is usually a number. Look for CI 75470. A colour index number looks like every other colour index number on a label, which is why people who read ingredient lists carefully still miss it in lipstick and blusher.

That asymmetry is the whole practical problem: food labelling helps you here and cosmetic labelling does not.

The names to know

Carmine. Cochineal extract. Carminic acid. Natural Red 4. E120. CI 75470. Crimson Lake.

Every alternative name we index is listed on the names page, which is quicker than remembering them.

“Natural colour” tells you nothing

A product can say “natural colour” on the front and use carmine, because carmine is about as natural as a colour gets. It comes from a living thing. That is a small, useful demonstration that the reassuring words on the front of a package are not the ones doing any work, which is the argument in what “natural” and “clean” legally mean.

A red product marketed as vegan will typically use beetroot, lycopene or a synthetic red instead, and will usually say so, because for that audience it is a selling point.

The wider picture, including why a certification mark is worth more than an ingredient list for this particular question, is on the page for people avoiding animal ingredients.
