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.

What a label must say

Words a food containing Acesulfame potassium is obliged to carry, quoted from the instrument that imposes them. A required statement is a fact about the regulation, not a finding about the substance — every rule below applies where the additive is authorised.

Every rule collected at what a label must say.

What it is made from

Synthesised from acetoacetic acid and sulfamic acid derivatives through a ring-closing reaction, then isolated as the potassium salt. It is not metabolised for energy and is excreted unchanged. No animal material is involved.

  • Vegan
  • Vegetarian

Proceed as directed under the method for Chromatography (High Performance Liquid Chromatography, FNP 5) using the following conditions and using 4-hydroxybenzoic acid ethyl ester as the reference substance: Column: 25 cm x 4.6 mm stainless steel Stationary phase: Reversed phase (C18 silica gel, 3 - 5 μm) Elution: Isocratic Mobile phase: Acetonitrile/0.01 mol/l tetrabutyl ammonium hydrogen sulfate (TBAHS) in water; 40/60 v/v Flow: About 1 ml/min Detector type: UV or Diode array, 227 nm Sample size: 20 μl of a 10 g/l solution of the sample in deionized water The chromatographic system must be capable of separating acesulfame K and 4-hydroxybenzoic acid ethyl ester with a resolution of 2. If peaks other than that due to acesulfame K appear within three times the elution time of acesulfame K, carry out a second run using 20 μl of a 0.2 mg/l solution of the sample. The sum of the areas of all peaks eluted in the first run within 3 times the elution time of acesulfame K elution time, except for the acesulfame K peak, does not exceed the peak area of acesulfame K in the second run.

Hazard reference values

The two committees set different figures. EFSA's acceptable daily intake is 9 mg/kg bw/day (2016); JECFA's is 15 mg/kg bw/day (1990). An acceptable daily intake is a reference value set by a committee, not a threshold above which harm begins. The lower figure is not a finding that the other body was wrong: the two work to different terms of reference, on their own timetables, and sometimes from different data. This site states both and chooses between them nowhere. See where the two committees differ.

Values set by assessing bodies. A body that has not set a value is not listed here.

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.

  1. EFSA 2025

    The FAF Panel found no genotoxicity concern for acesulfame K (E 950) or its degradation products, and set an ADI of 15 mg/kg bw/day, replacing the SCF's ADI of 9 mg/kg bw/day. Exposure was generally below the ADI; it identified a potential genotoxicity concern for the impurity 5-chloro-acesulfame and recommended a maximum limit or further data.

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 950?
E 950 is Acesulfame potassium. Acesulfame potassium is an intense sweetener roughly two hundred times as sweet as sugar, usually blended with other sweeteners to mask its aftertaste. It is used in soft drinks, confectionery, dairy products and tabletop sweeteners.
What is Acesulfame potassium used for in food?
It is listed as a sweetener — the role Canada, Codex, the EU and the US assign it. This page shows every function each regulator records, with the citation for each.
Where is Acesulfame potassium 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 Acesulfame potassium vegan?
Yes. Acesulfame potassium is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
