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.
| European Union | — | 46 several limits, 22 no quantity stated |
|---|---|---|
| Great Britain | — | 66 quantum satis |
| South Korea | — | 1 no quantity stated |
| United States | — | 1 no quantity stated |
| Codex Alimentarius | — | 1 GMP |
No regulator sets a figure for Ethyl cellulose. That is not an absence of control: where the listing says quantum satis or good manufacturing practice, the quantity is limited to what the effect requires.
GRAS notices to the FDA
A GRAS notice is a company’s conclusion that a substance is generally recognised as safe for the use it describes. FDA’s letter responds to that conclusion, for that notifier and that use. It is not a listing in 21 CFR, and it is not counted as a US permission above. The substance and use are as FDA’s inventory words them; this site matched the notice to this page by exact name.
GRN No. 470 · Ethyl cellulose · Dow Wolff Cellulosics
Intended use: For uses including viscosity modification, thickening, film-forming, stabilization, acting as a filler, and for thermal gelation in grain products, vegetables, fruits, milk and milk products, legumes, nuts and seeds, fats and oils, sugars and sweets, and beverages at levels ranging from 0.0075 to 5%
FDA’s response (2013-12-16): FDA has no questions
What it is made from
Made by treating purified cellulose with ethylating agents. Unlike most modified celluloses it is not water-soluble, which is what makes it useful as a barrier film.

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 |
|---|---|---|
| Assay | no less than 44 % | no less than 44 % |
| Loss on drying | no more than 3 % | no more than 3 % |
| Sulphated ash | no more than 0.4 % | no more than 0.4 % |
| Lead | no more than 0.5 mg/kg | no more than 2 mg/kg |
| Arsenic | no more than 0.5 mg/kg | — |
| Mercury | no more than 0.5 mg/kg | — |
| Cadmium | no more than 0.5 mg/kg | — |
One parameter differs between the two documents. A difference is not a disagreement about safety: the two are revised on their own cycles, and an assay or a drying loss can be measured against a different preparation of the substance, which is why only the contaminant ceilings are marked. Within the EU the EU's figure is the one that binds.
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.

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 2018
The ANS Panel concluded, using read-across between the celluloses, that there was no genotoxic or carcinogenic concern for unmodified and modified celluloses (E 460–E 469), that no numerical ADI is needed, and that there would be no safety concern at the reported uses and use levels.
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 462?
- E 462 is Ethyl cellulose. Ethylcellulose is a film former and binder used in coatings and to encapsulate flavours, and as a structuring agent in some confectionery.
- What is Ethyl cellulose used for in food?
- It is listed as a thickener and a stabiliser — the role Codex and the US assign it. This page shows every function each regulator records, with the citation for each.
- Where is Ethyl cellulose permitted?
- Of the seven regulators this site reads, the EU, Great Britain, South Korea, the US 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 Ethyl cellulose vegan?
- Yes. Ethyl cellulose is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
