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 | 5,000 mg/kg | 1 numeric limit, 55 GMP |
|---|---|---|
| Canada | 5,000 mg/kg – 500,000 mg/kg | 11 numeric limit |

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 92 % | no less than 97 % |
| Loss on drying | no more than 7 % | no more than 7 % |
| Sulphated ash | no more than 0.3 % | no more than 0.05 % |
| Lead | no more than 0.3 mg/kg | no more than 2 mg/kg |
| Arsenic | no more than 0.1 mg/kg | — |
| Mercury | no more than 0.2 mg/kg | — |
| Cadmium | no more than 0.1 mg/kg | — |
3 parameters differ 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.

- METHOD OF ASSAY
- Transfer about 125 mg of the sample, accurately weighed, to a 300 mL Erlenmeyer flask, using about 25 mL of water. Add 50.0 mL of 0.5N potassium dichromate and mix. Carefully add 100 mL of sulfuric acid and heat to boiling. Remove from heat, allow to stand at room temperature for 15 min and cool in a water bath. Transfer the contents into a 250 mL volumetric flask, rinse flask with distilled water, add rinsings to the volumetric flask and dilute with water almost to volume. Allow the volumetric flask to reach room temperature (25°); then make up to volume with water and mix. Titrate a 50.0 mL aliquot with 0.1 N ferrous ammonium sulfate using 2 or 3 drops of ortho-phenanthroline TS as the indicator and record the volume required as S in mL. Perform a blank determination and record the volume of 0.1 N ferrous 3 out of 3 ammonium sulfate required as B in mL. Calculate the percentage of cellulose in the sample using the formula: ( 𝐵𝐵 − 𝑆𝑆 ) × 𝑊𝑊 Where: - W is the weight of sample taken, in mg, corrected for loss on drying.

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 460?
- E 460 is Powdered cellulose. Powdered cellulose is milled plant fibre used as an anticaking agent and a source of dietary fibre, notably in shredded cheese and baked goods.
- What is Powdered cellulose used for in food?
- It is listed as a bulking agent — the role Canada and Codex assign it. This page shows every function each regulator records, with the citation for each.
- Where is Powdered cellulose 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 Powdered cellulose vegan?
- Yes. Powdered cellulose is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
