Methylcellulose is a thickener with an unusual property: it gels when heated and melts when cooled, the reverse of gelatin. That behaviour is what holds many plant-based burgers together during cooking.

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.
| Australia and New Zealand | — | 54 GMP |
|---|---|---|
| Canada | — | 3 GMP |
| European Union | — | 46 several limits, 2 quantum satis, 22 no quantity stated |
| Great Britain | — | 68 quantum satis |
| Japan | — | 1 no quantity stated |
| South Korea | — | 1 no quantity stated |
| United States | — | 1 no quantity stated |
| Codex Alimentarius | — | 18 GMP |
No regulator sets a figure for Methyl 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.
What it is made from
Made by treating purified cellulose with methylating agents. The cellulose comes from wood pulp or cotton; no animal material is involved.

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 25 % | no less than 25 % |
| Loss on drying | no more than 10 % | no more than 10 % |
| Sulphated ash | no more than 1.5 % | no more than 1.5 % |
| Lead | no more than 0.1 mg/kg | no more than 2 mg/kg |
| Arsenic | no more than 0.1 mg/kg | — |
| Mercury | no more than 0.1 mg/kg | — |
| Cadmium | no more than 0.1 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 461?
- E 461 is Methyl cellulose. Methylcellulose is a thickener with an unusual property: it gels when heated and melts when cooled, the reverse of gelatin. That behaviour is what holds many plant-based burgers together during cooking.
- What is Methyl cellulose used for in food?
- It is listed as an emulsifier, a thickener and a stabiliser — the role Canada, Codex and the US assign it. This page shows every function each regulator records, with the citation for each.
- Where is Methyl cellulose permitted?
- Of the seven regulators this site reads, Australia and New Zealand, Canada, the EU, Great Britain, Japan, 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 Methyl cellulose vegan?
- Yes. Methyl cellulose is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
