The short answer
Shellac (E904) is a glaze made from the secretion of the lac insect, used to shine sweets, chocolates, and pills. Scholars differ: some permit it by analogy to honey (a secretion, not the insect's body), while many hold the mainstream view that insect-derived products should be avoided — and most UK halal certifiers won't certify products containing it.
The short version
Shellac — also called confectioner's glaze, resinous glaze, or E904 — is a resin secreted by the female lac insect. It puts the shine on candy-coated sweets, apples, and coated tablets.
The disagreement
- Permitting view: it's a secretion distinct from the insect's body, comparable to honey from bees, so some scholars allow it.
- Cautious / mainstream view: insects (other than locusts) are generally not consumed, so many avoid it. Major UK certifiers (HFA, HMC) typically do not certify products containing E904.
What to check yourself
- Watch for: shellac, confectioner's/resinous glaze, E904, "glazing agent".
- If you follow the cautious view, avoid it; carnauba wax (plant) is a common halal glaze alternative.
