E466, also called cellulose gum or sodium carboxymethyl cellulose, is generally halal by its plant-cellulose source. It is not gelatin and does not name an animal protein. The EU specification describes modified cellulose, while US labels commonly use its ingredient name. Check the rest of the product, particularly flavours and fat-derived emulsifiers, before treating the complete food as suitable. [1] [6]
Three names for the ingredient
SANHA lists sodium carboxymethylcellulose E466 as Halaal. This is named halal-authority ingredient guidance, separate from a regulator’s identity assessment. It is not a certificate for every supplier preparation or finished food containing the additive. [6]
E466 identifies sodium carboxymethyl cellulose, often shortened to CMC. “Cellulose gum” is a common food-label name. The underlying cellulose is a plant structural material; chemical modification helps it perform a thickening or stabilising job in food. EFSA’s review describes the material and specifications for this cellulose family. [1]
The word “gum” describes how the ingredient behaves, not an animal species. Likewise, a food becoming thick does not prove it contains gelatin. Starch, pectin, gums and animal gelatin can all affect texture through different materials and processes. Our gelatin guide and pectin guide address those distinct ingredients.
| Label wording | What it names | Practical implication |
|---|---|---|
| E466 / cellulose gum / sodium CMC | A modified cellulose additive | Plant-cellulose origin; check other components |
| Cellulose gel | A different cellulose presentation | Do not automatically rewrite it as E466 |
| Gelatin / gelatine | An animal-derived protein | Species and halal source evidence matter |
| Stabiliser blend | A preparation with multiple possible ingredients | Get the complete list |
A real frozen-dessert declaration
Blue Bunny’s US Vanilla frozen dairy dessert page names both cellulose gel and cellulose gum. Its list also includes mono- and diglycerides, flavours and several other gums. That is a useful reading example: identifying the cellulose gum does not answer the source of every other ingredient. [2]
The manufacturer describes this named product as a frozen dairy dessert. We have not relabelled it as a pure ice cream or assigned a brand-wide halal certificate. A different Blue Bunny variety or imported tub needs its own declaration. The ice-cream and frozen-dessert guide covers the wider recipe checks.
A different application: tortilla wraps
Mission’s US Gluten Free Chickpea Tortilla Wraps record also contains cellulose gum and describes that specific product as vegan-friendly. It shows the ingredient outside a dairy dessert. That statement belongs to the named wraps; it is useful evidence for them, rather than permission to transfer one company claim to another recipe. [3]
| Named variant | Cellulose declaration | Separate evidence needed |
|---|---|---|
| Blue Bunny Vanilla frozen dairy dessert | Cellulose gel and cellulose gum | Other emulsifiers and flavours |
| Mission Chickpea Tortilla Wraps | Cellulose gum; product-specific vegan-friendly statement | Certification where required by your standard |
We reviewed public ingredient records and the cited technical sources on 14 October 2026. We did not handle a retail pack or run a private barcode/app scan. Match the named product and market to your own label before applying this example.
Why the number alone can confuse a scanner
An EU-style label can give a function and code, while a US record may write “cellulose gum”. If you compare two records by looking only for the digits 466, you can miss the same ingredient written by name. Conversely, not every word containing “cellulose” identifies precisely the same additive. Read the full term and keep its context.
The E-number reference translates common codes. It does not turn a short code into supplier-level assurance. If an app result flags a term, compare the detected words with the printed panel before asking about the material. A blurred photograph or incomplete database entry can produce a question that the actual label already answers.
What should still be checked?
On a dessert, flavours, gelatin, colours or fat-based emulsifiers may deserve attention. On a wrap, the open question may concern enzymes or mono- and diglycerides. These are separate materials. A product can have a straightforward E466 finding and an unresolved source elsewhere.
If you buy a stabiliser preparation rather than a retail food, request its complete specification. The front name can describe the main ingredient without listing every carrier or component. For product-level certification, verify which formulation and site the current certificate covers. IFANCA’s guidance treats complex additives and production controls as part of assurance. [4]
How to record a useful result
- Record the full term: E466, cellulose gum or sodium carboxymethyl cellulose.
- Match the product name, flavour and market to the retrieved record.
- Read the whole ingredient list, including compound ingredients.
- Separate resolved cellulose from any unresolved fat or flavour source.
- Verify a printed halal mark with its issuing certifier when needed.
A clear outcome might be: “Cellulose gum identified; source question remains for the mono- and diglycerides.” That is more useful than treating every stabiliser as doubtful or giving every additive the same answer. The Mushbooh explanation shows how to keep uncertainty tied to the missing fact.
Food identity and dietary advice are separate
This page answers the halal source question. A regulatory safety assessment considers different questions, including permitted use and exposure. Neither subject should be substituted for the other. If you need advice about a medical diet, a halal ingredient finding does not provide it.
For ordinary shopping, the key point is simple: E466 is a cellulose-based stabiliser, not an undisclosed name for pork gelatin. You still need the complete packet to decide about the food around it.
Frequently asked questions
Is cellulose gum made from pork?
E466 is based on plant cellulose, not pork protein or fat. Check any additional ingredients in a stabiliser preparation or finished food separately.
Is cellulose gum the same as gelatin?
No. They can affect texture, but cellulose gum is a modified cellulose ingredient and gelatin is an animal-derived protein.
Why does the US label have no E466 code?
A US label can use the ingredient name cellulose gum. The absence of a European code does not imply a different raw material.
Does E466 make the entire dessert halal?
No. A dessert may also contain source-dependent emulsifiers, flavours or gelatin that need their own evidence.
What if the database and tub disagree?
Use the printed tub and ask the manufacturer about that barcode and lot. Product records can lag behind reformulations.
