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 | 500 mg/kg – 10,000 mg/kg | 14 numeric limit, 3 quantum satis |
|---|---|---|
| Great Britain | 500 mg/kg – 10,000 mg/kg | 13 numeric limit, 3 quantum satis |
| Codex Alimentarius | 50 mg/kg – 20,000 mg/kg | 53 numeric limit |
What it is made from
Made by esterifying sorbitol with palmitic acid, which may come from palm oil or from animal fat.
- Vegan status depends on the source
- Vegetarian status depends on the source
- May raise a halal question
- May raise a kosher question
This is not an omission. What this additive is made from is not fixed — depending on the manufacturer it may be plant, animal or microbial in origin, nobody is required to say which, and the same product can change source between production runs. Ask the manufacturer if it matters to you; a label cannot answer it.

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 95 % | stated in prose |
| Lead | no more than 2 mg/kg | — |
| Arsenic | no more than 3 mg/kg | — |
| Mercury | no more than 1 mg/kg | — |
| Cadmium | no more than 1 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.

Hazard reference values
EFSA and JECFA have both assessed Sorbitan monopalmitate and their conclusions are not two comparable figures — EFSA records 10 mg/kg bw/day, JECFA temporary: 0–25 mg/kg bw/day (as total polyoxyethylene (20) sorbitan esters). 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.
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 2017
The ANS Panel found no genotoxicity concern for the sorbitan esters (E 491–E 495) and derived a single group ADI of 10 mg/kg bw/day expressed as sorbitan (equivalent to 26 mg sorbitan monostearate/kg bw/day), replacing two separate SCF group ADIs. Exposure did not exceed this ADI in any population group.
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 495?
- E 495 is Sorbitan monopalmitate. Sorbitan monopalmitate is an emulsifier used in cake mixes, icings and confectionery.
- What is Sorbitan monopalmitate used for in food?
- It is listed as an emulsifier — the role Codex assigns it. This page shows every function each regulator records, with the citation for each.
- Where is Sorbitan monopalmitate permitted?
- Of the seven regulators this site reads, the EU, Great Britain 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 Sorbitan monopalmitate vegan?
- It depends on the source, and a label will not tell you. Sorbitan monopalmitate can be made from plant or animal material, manufacturers are not obliged to say which, and the same product can change between production runs. Anyone who needs to know has to ask the manufacturer.
