Doubtful — depends on source
E904 (Shellac) is a resin secreted by the lac insect and used as a glaze; scholars differ on insect secretions, so it is treated as doubtful (mushbooh).
Shellac is a resin secreted by the female lac insect on trees, refined into flakes and dissolved to make a food glaze. It gives a shiny coating to sweets, chocolates and coated tablets, and is used to wax some fruits.
The lac resin is scraped from tree branches, purified and processed into shellac. As a food glaze it is usually dissolved in ethanol and applied as a thin coating (the solvent evaporates).
Shellac is treated as doubtful because scholars differ on insect secretions: some permit it by analogy with honey (a product secreted by an insect, not the insect's body), while others avoid it because it is insect-derived and may carry insect fragments. A further point to check is that food-grade shellac is typically applied using an ethanol carrier; opinions differ on residual solvent. Given the disagreement, the cautious approach is to verify or avoid.

It is a resin secreted by the lac insect, refined into a glaze. It is a secretion rather than the insect's body, which is why scholars differ on it.
