Is Shellac (E904) Vegan?

In the United States, shellac on food packaging most often appears as 'confectioner's glaze,' 'resinous glaze,' 'pure food glaze,' or 'natural glaze,' and none of those terms indicates an insect origin. Careful label readers miss it easily. On pharmaceutical products it may be listed as 'pharmaceutical glaze.' In the European Union, the ingredient is declared either by name or by its additive number, E904.

Fresh produce presents an additional gap. Apples, citrus fruits, and other produce are frequently coated with shellac or wax blends after harvest to reduce moisture loss and add shine, but loose fruit typically carries no ingredient label at the point of sale. Disclosure practices vary by country. In some markets, signage may note post-harvest treatments, while in others no information is provided. Shoppers who want to avoid shellac on produce generally rely on asking retailers, buying unwaxed or organic-certified fruit where coating rules differ, or peeling the fruit.

Several plant-derived glazing agents perform a similar function to shellac in food production. Carnauba wax (E903), obtained from the leaves of the Brazilian carnauba palm, is the most widely used substitute. It appears on many candy and supplement labels. Candelilla wax (E902), derived from a shrub native to Mexico and the southwestern United States, is another established option. Zein is a protein extracted from corn. Some coatings for confectionery and tablets use it.

For pharmaceutical and supplement coatings, cellulose-based films such as hydroxypropyl methylcellulose (HPMC) are common vegan-friendly alternatives and are standard in many vegetarian capsule products. Functionally, these substitutes provide gloss and moisture barriers comparable to shellac, though manufacturers sometimes prefer shellac for its particular hardness and shine. E903 and E902 indicate plant-derived waxes. E904 always indicates shellac.

The most commonly cited food sources of shellac are shiny candies: jelly beans, chocolate-covered nuts and raisins, candy-coated chocolates, and some sprinkles and decorative dragees. A shellac-based glaze frequently provides the glossy finish. That finish keeps the products from sticking together and gives them shelf appeal.

Beyond confectionery, shellac appears in places many consumers do not expect. Waxed supermarket apples and citrus fruits often carry a shellac coating. Coated tablets, both over-the-counter medications and dietary supplements, may use pharmaceutical glaze. Some coffee beans and chocolate-covered coffee beans are glazed. Outside of food, shellac is a traditional wood finish. It also turns up in some nail products and cosmetics, though gel manicures marketed under the 'shellac' name are not necessarily made with the resin. On food labels the term is usually 'confectioner's glaze,' so checking for that phrase, along with E904, is the most reliable way to identify it.

E904 is a glazing agent. Codex Alimentarius defines that class as additives applied to the outside of a food to give it a shiny appearance or a protective coating, and its international numbering system lists the substance as INS 904 under the name bleached shellac. The EU specification describes E904 as purified and bleached lac, the resin secreted by the lac insect.

The European Food Safety Authority published a re-evaluation of E904 in 2024. It set an acceptable daily intake of 4 mg per kilogram of body weight per day for wax-free shellac made by physical decoloring, and it treats that figure as temporary for wax-free shellac bleached with chemicals until new data on organochlorine impurities arrive. The review covers safety alone. Every grade of E904 still comes from the lac insect, so the vegan verdict stays the same.

EU law authorizes shellac for a defined list of foods. When EFSA reviewed the additive in 2024, that list ran to 11 food categories. In eight of them shellac may serve only as a glaze: chocolate products; other confectionery including breath-freshening microsweets; chewing gum; decorations, coatings and non-fruit fillings; small fine bakery wares coated with chocolate; snacks based on potato, cereal, flour or starch; processed nuts; and coffee beans. Food supplements in solid form such as tablets are also on the list.

The last two categories cover fresh produce and eggs. Shellac may coat the skin of citrus fruit, melons, apples, pears, peaches, pineapples, pomegranates, mangoes, avocados and papayas, and it may be used as a glaze on nuts. It is also permitted on the surface of unpeeled boiled eggs. A 2026 amendment added foods for special medical purposes in tablet and coated tablet form.

On packaged food the EU ingredient list names the category first, so shellac appears as glazing agent followed by shellac or E904. Plant waxes can fill the same slot. Codex classes candelilla wax (E902) and carnauba wax (E903) as glazing agents alongside shellac, and EFSA notes that EU law authorizes carnauba wax in that role. E901 in that position means beeswax, an insect product that vegans also avoid.
