Is Shellac (E904) Vegan? The Ingredient Behind Shiny Candy

✗ Not vegan Shellac (E904) is not vegan. It is a resin secreted by the lac insect and scraped off tree branches in India and Thailand, and huge numbers of insects are killed or displaced to collect it. On sweet wrappers it rarely says shellac: look for confectioner's glaze.

What is shellac, and what is E904?

Shellac is a natural resin produced by the lac insect, Kerria lacca. It is a tiny sap-feeding bug that lives on host trees across India, Thailand and neighbouring countries. Females settle on the twigs in their thousands, drink the sap, and secrete a hard reddish resin that hardens into a protective crust over the whole colony.

Farmers cut the encrusted twigs. That raw material is called sticklac, and it is crushed, sieved and repeatedly washed to separate resin from insect bodies and bark, yielding seedlac. Heat pressing or solvent extraction turns that into the amber flakes sold as shellac. In food, the refined resin carries the additive number E904.

It earns its place because no plant wax quite matches it. Shellac dries into a hard, glossy, moisture-blocking film that survives handling, which is why it ends up on sweets, tablets and fruit, and why it doubles as a woodworking finish.

Why shellac is not vegan

The Vegan Society's definition of veganism targets exploitation of animals, and its Vegan Trademark standards spell out what "animal" covers: the entire animal kingdom, meaning all vertebrates and all multicellular invertebrates. Insects are in. That settles it for the mainstream vegan standard, in the same way and for the same reason that honey is not vegan. Shellac is an animal secretion, so it is out.

Scale sharpens it. The figure quoted throughout the trade is around 300,000 lac insects per kilogram of resin.

The part where honest people disagree

Some vegans argue that shellac is closer to a by-product than a slaughter product, and the production detail is genuinely more mixed than most articles admit. Growers use two harvest timings. Cutting the twigs after the nymphs have swarmed lets that generation leave first, while cutting before swarming destroys the insects outright, and both are standard practice depending on the crop. Lac dye, the red colourant, is recovered from the insect bodies themselves.

What is not in dispute: insect bodies are a routine component of raw sticklac, they are washed out during processing, and cutting the branches ends the colony. A minority of individuals weigh that as incidental and keep eating it. Every major vegan certifier does not.

The label names shellac hides behind

This is the practical problem. Manufacturers are allowed a small dictionary of alternative names, and none of them mention an insect. In the United States, "confectioner's glaze" and "resinous glaze" are both legally compliant declarations for the same resin.

What the label says	What it actually means	Vegan?
Shellac	The resin itself, under its own name. Common on fruit signage and in pharma.	No
E904	The EU additive number for shellac.	No
Confectioner's glaze / confectioner's resin	The standard US wording on sweets and coated snacks.	No
Resinous glaze	The same resin again, different wording.	No
Natural glaze / pure food glaze	Vague marketing phrasing that in practice means shellac.	No, unless the maker names a plant wax
Lac resin / lac	Shellac under its raw-material name.	No
Pharmaceutical glaze	Shellac used to coat tablets and capsules.	No
Carnauba wax / E903	Wax from the leaves of a Brazilian palm. The usual plant substitute.	Yes

The word shellac almost never appears on a sweet wrapper. If a label says confectioner's glaze, resinous glaze or simply "natural glaze", treat it as shellac until the manufacturer tells you otherwise.

Glazing agents also sit at the very end of an ingredient list, in the smallest print, past the flavourings. That is where eyes stop reading, which is why shellac makes so many hidden animal ingredient lists.

Where shellac actually turns up

Sweets, coated snacks and gum

Follow the shine. Jelly beans, chocolate lentils, candy corn, chocolate-coated raisins and peanuts, coated coffee beans, some chewing gum, liquorice, marzipan, sprinkles and cake decorations are all classic shellac territory. Formulations vary by brand and by market, so a product that is clear in your country may not be clear in another. Our roundup of accidentally vegan snacks covers the safe bets, and dark chocolate has its own separate traps.

Waxed fruit, and the loophole nobody mentions

Shellac is authorised in the EU as a surface treatment for fruit alongside beeswax (E901), carnauba wax (E903) and microcrystalline wax (E905). Commission Regulation (EU) No 1147/2012 sets the shellac list: citrus fruit, melons, apples, pears, peaches, pineapples, pomegranates, mangoes, avocados and papayas. Bananas sit on the beeswax list rather than the shellac one.

Here is the gap. Additive declarations belong to prepacked food, and fruit sold loose by the piece often carries no ingredient list at all, so the glaze on that apple may never be declared anywhere you can see it. Germany requires a visible "waxed" indication on loose produce, but the rules are not uniform. The coating sits on the skin, so peeling or a hard scrub handles most of it, and a good greengrocer can tell you which lines are treated.

Tablets, capsules and supplements

Shellac is a workhorse coating in pharmacy, used for gloss and for delayed release, and it appears on labels as "shellac" or "pharmaceutical glaze". Supplements use it the same way, and the EU has extended E904's authorisation to cover tablets in foods for special medical purposes.

Excipients are listed in the patient information leaflet rather than on the box. If a prescribed medicine turns out to contain shellac, talk to your pharmacist about an alternative formulation rather than skipping doses.

Nail polish and the "Shellac" manicure

Outside food, lac resin has long been used as a film former in nail lacquer, and some formulations still contain it. Confusingly, the salon Shellac manicure is a trademarked brand of UV-cured gel polish, so the name is marketing rather than an ingredient declaration. Read the list, or ask the salon.

Insect and animal glazing agents at a glance

Shellac travels in company. If you are scanning an ingredient list for E904, these are the neighbours worth checking in the same pass.

E-number	Name	Source	Vegan?
E901	Beeswax (white and yellow)	Honeybee combs	No
E902	Candelilla wax	Candelilla shrub (plant)	Yes
E903	Carnauba wax	Leaves of the carnauba palm (plant)	Yes
E904	Shellac	Resin secreted by the lac insect	No
E905	Microcrystalline wax	Refined petroleum (mineral)	Yes, no animal input
E913	Lanolin	Grease from sheep's wool	No
E120	Carmine / cochineal	Crushed cochineal insects	No

Two deserve a click. E120 carmine is the other big insect additive and haunts the same sweets aisle, while lanolin (E913) matters beyond glazing as the starting material for most vitamin D3 supplements. The complete list of non-vegan E-numbers ranks the rest.

Replacements exist. Carnauba wax is the standard swap, candelilla wax covers similar ground, and zein, a protein glaze made from corn, is being adopted specifically to take shellac's place on confectionery.

Is shellac vegetarian?

Traditionally yes. The insect is not eaten, the resin is a secretion, and by that logic shellac sat in the same bracket as honey and beeswax for decades. That consensus cracked in 2021.

ISO 23662:2021 sets international criteria for foods labelled suitable for vegetarians or vegans, and it excludes shellac from both categories. The UK Vegetarian Society followed: from January 2022 it stopped approving new shellac products under its trademark criteria, and existing licensees had until 31 December 2023 to reformulate or drop the logo.

So the honest position in 2026: plenty of vegetarians still eat shellac without a second thought, but the formal standards no longer call it vegetarian. Either way, the label routine is the one in our guide to reading food labels as a vegan.

Is E904 safe to eat?

The European Food Safety Authority published a re-evaluation of shellac (E904) in 2024, setting an acceptable daily intake of 4 mg per kg of body weight per day for wax-free shellac decoloured by physical means. The panel called that figure temporary for chemically bleached shellac while impurity data is gathered. A few age groups top the ADI at the high end of the exposure estimates, but the overshoot was judged too small to be a safety concern. For anything personal, ask a doctor or a registered dietitian.

Frequently asked questions

Is confectioner's glaze the same as shellac?

Yes. Confectioner's glaze, confectioner's resin, resinous glaze and pharmaceutical glaze are all trade names for shellac, the resin secreted by the lac insect. In the EU it carries the additive number E904. None of them are vegan.

Are insects killed to make shellac?

Yes, in large numbers. The figure quoted throughout the trade is around 300,000 lac insects per kilogram of resin. Some growers cut the twigs after the young have swarmed, so that generation gets away, but others harvest before swarming. Either way, insect bodies are washed out of the raw sticklac and cutting the branches ends the colony.

Is shellac vegetarian?

Under most everyday definitions yes, because the insect itself is not eaten. The formal standards now disagree. ISO 23662:2021 excludes shellac from both vegetarian and vegan foods, and the UK Vegetarian Society stopped approving new shellac products under its trademark, giving existing licensees until 31 December 2023 to reformulate.

Which sweets contain shellac?

Usually anything with a hard shine: jelly beans, chocolate lentils, candy corn, chocolate-coated raisins and peanuts, some chewing gum, sprinkles and cake decorations. Recipes differ by brand and by country, so read the current ingredient list rather than trusting a product you cleared years ago.

Is shellac nail polish vegan?

Not if the bottle actually contains lac resin, which some traditional nail lacquers still use as a film former. The salon Shellac manicure is a trademarked gel-polish brand name rather than a statement about ingredients, so read the ingredient list or ask the salon instead of going by the name.
