How much is permitted
A listing usually limits the quantity as well as the food. Only one of the forms that takes is a figure: quantum satis and good manufacturing practice permit the amount the technological effect requires and no more, which is a limit rather than the absence of one. Figures below are the range across every food category this page is listed in, and categories differ between regulators — see how much is permitted.

The two specifications, compared
The European Union sets identity and purity by regulation; JECFA publishes its own through FAO, advisory until a country adopts it. Both documents are below in full. These are the parameters each puts a number on.
| Parameter | European Union | JECFA |
|---|---|---|
| Loss on drying | no more than 6 % | no more than 6 % |
| Lead | no more than 2 mg/kg | no more than 2 mg/kg |
The two documents state the same figures for every parameter compared here.
How the EU defines it
The legal specification an additive must meet to be sold as this E number in the EU — what it is, how it may be made, and the purity it must reach. From Commission Regulation (EU) No 231/2012.
E 904 Shellac
Shellac is the purified and bleached lac, the resinous secretion of the insect Laccifer (Tachardia) lacca Kerr (Fam. Coccidae). The wax is removed by filtration.

INS 904 Shellac, bleached
Shellac is a polyester resin obtained from lac, the resinous secretion of the insect Laccifer ( Tachardia ) lacca Kerr (Fam. Coccidae ). Bleached shellac is obtained by dissolving the lac in aqueous sodium carbonate, followed by bleaching with sodium hypochlorite, precipitation of the bleached lac with dilute sulfuric acid solution, and drying; wax-free bleached shellac is prepared by further treatment whereby the wax is removed by filtration.
Synonyms: INS No. 904
Assay, identification and purity criteria
Description and assay
- Specification history
- Prepared at the 55th JECFA (2000) and published in FNP 52 Add 8 (2000), superseding specifications prepared at the 51st JECFA (1998) and published in FNP 52 Add 6 (1998). An ADI "Acceptable, present uses (as a coating, glazing, and surface-finishing agent externally applied to food) not of toxicological concern" was established at the 39th JECFA (1992).
- C.A.S. number
- 9000-59-3
- DESCRIPTION
- Bleached shellac: off-white to tan, amorphous granular resin; wax-free bleached shellac: light yellow, amorphous, granular resin
- FUNCTIONAL USES
- Coating agent, glazing agent, surface finishing agent
Identification
- Colour reaction
- To 50 mg of the sample add a few drops of a solution of 1 g ammonium molybdate in 3 ml of sulfuric acid. A green colour is produced, changing to lilac when the solution is neutralized with 6 N ammonium hydroxide.
- Solubility (Vol. 4)
- Insoluble in water; freely (though very slowly) soluble in ethanol; slightly soluble in acetone and ether
- Acid value
- Between 60 and 89 See description under TESTS
- Test: Acid value
- Dissolve about 1 g of finely ground sample, accurately weighed, in 50 ml of alcohol previously neutralized to phenolphthalein with sodium hydroxide, and titrate with 0.1 N potassium hydroxide. Determine the end point using phenolphthalein TS or a potentiometer. If phenolphthalein is used, titrate until the pink colour persists for at least 30 sec. Calculate the acid value by the formula 56.1V x N/W, in which V is the exact volume, in ml, N is the exact normality of the sodium hydroxide solution, and W is the weight, in g, of sample taken, calculated on the dry basis.
Purity criteria
- Loss on drying (Vol. 4)
- Not more than 6% (40 o , 4 h, then room temperature over silica gel, 15 h)
- Rosin
- Dissolve 2 g of the sample in 10 ml of dehydrated ethanol, and add slowly, with shaking, 50 ml of solvent hexane. Transfer to a separator, wash with two 50-ml portions of water, and discard the washings. Filter the solvent layer, evaporate it to dryness, and to the residue add 2 ml of a mixture of 1 volume of liquefied phenol and 2 volumes of methylene chloride. Stir and transfer a portion of the mixture to a cavity of a colour-reaction plate. Fill an adjacent cavity with a mixture of 1 volume of bromine and four volumes of methylene chloride, and cover both cavities with an inverted watch glass. No purple or deep indigo blue colour is produced in or above the liquid containing the sample residue.
- Wax
- Bleached shellac: not more than 5.5%; wax-free bleached shellac, not more than 0.2% See description under TESTS
- Lead (Vol. 4)
- Not more than 2 mg/kg Determine using an atomic absorption technique appropriate to the specified level. The selection of sample size and method of sample preparation may be based on the principles of the method described in Volume 4, “Instrumental Methods”.
- Test: Wax
- Transfer about 10 g of finely ground sample, accurately weighed, and 2.5 g of sodium carbonate to a 200-ml tall-form beaker. Add 150 ml of hot water, immerse the beaker in a boiling water bath, and stir until the sample is dissolved. Cover the beaker with a watch glass, heat for 3 h without agitation, and cool in a cold water bath. When the wax has floated to the surface, filter the mixture through medium-speed quantitative ashless filter paper, transferring the wax to the paper, and wash the filter with water. Pour 5 to 10 ml of ethanol onto the filter to accelerate drying. Wrap the paper loosely in a large piece of filter paper, bind with a piece of fine wire, and dry with the aid of gentle heat. Extract with chloroform in a suitable continuous extraction apparatus for 2 h, using a previously dried and accurately weighed flask to receive the extracted wax and solvent. Evaporate the solvent, dry the wax at 105 o to constant weight, and calculate the percentage of wax.

The EU re-evaluation programme
Every additive authorised in the EU before 20 January 2009 was put back through EFSA by Commission Regulation (EU) No 257/2010, and this one is named in it. What the Regulation required is below; whether the opinion has since been published is not something this site records.
- To be evaluated by 31 December 2018. Named in Annex II, Part II, point 4 as “Shellac”, among the additives given priority within its class.
Hazard reference values
EFSA and JECFA have both assessed Shellac, bleached and their conclusions are not two comparable figures — EFSA records 4 mg/kg bw/day, JECFA not specified. An acceptable daily intake is a reference value set by a committee, not a threshold above which harm begins. “Not specified”, “not limited” and “not allocated” are conclusions, not missing data, and they are shown in the words each body used rather than reduced to a number. See where the two committees differ.
| Type | Value | Population | Assessed by | Opinion |
|---|---|---|---|---|
| ADI | not specified | — | JECFA | 1992 |
| ADI | 4 mg/kg bw/day | consumers | EFSA | not identified in the dataset |
Evidence and how bodies read it
What assessing bodies concluded
Each conclusion is paraphrased in the body's own framing, from the published opinion linked beneath it. Where bodies differ, both stand; this site does not adjudicate between them or add a view of its own.
EFSA 2024
The FAF Panel derived an ADI of 4 mg/kg bw/day for wax-free shellac (E 904) produced by physical decolouring, temporary for chemically bleached shellac pending data on organochlorine impurities, and not applicable to wax-containing shellac. It considered the small exceedance of the ADI in some age groups not to indicate a safety concern, and recommended separate specifications for each manufacturing process.
Common questions
Assembled from what is above, in the words the questions are usually asked in. Each answer is the same statement the relevant section makes, with the same citations behind it.
- What is E 904?
- E 904 is Shellac, bleached. Shellac is the glaze on many sweets, chocolate coatings and coated fruit, and the coating on many tablets. It is a resin secreted by the lac insect and is not vegan; whether it is vegetarian is contested, because insects are killed during harvesting.
- What is Shellac, bleached used for in food?
- It is listed as a glazing agent — the role Canada, Codex and the US assign it. This page shows every function each regulator records, with the citation for each.
- Where is Shellac, bleached permitted?
- Of the seven regulators this site reads, Australia and New Zealand, Canada, the EU, Great Britain, South Korea and the Codex standard permit it. Each permission is for named foods at named levels, not a blanket one; the table on this page gives them with citations.
- Is Shellac, bleached vegan?
- No. Shellac, bleached is animal-derived, and is not vegetarian either. This page says what it is made from.
