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 | — | 44 no quantity stated |
|---|---|---|
| European Union | 1 mg/kg – 200 mg/kg | 27 numeric limit |
| Great Britain | 1 mg/kg – 200 mg/kg | 23 numeric limit, 2 several limits |

What a label must say
Words a food containing Ponceau 4R (Cochineal red A) 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.
‘name or E number of the colour(s)’: may have an adverse effect on activity and attention in children.
A food containing any of six colours must carry this statement. Regulation (EC) No 1333/2008, Article 24 and Annex V · Assimilated Regulation (EC) No 1333/2008, Annex V
Except: Foods where the colour was used for health or other marking on meat products, or for stamping or decorative colouring on eggshells. Beverages containing more than 1.2 % alcohol by volume.
Every rule collected at what a label must say.
What it is made from
Synthesised from petroleum-derived aromatic intermediates by diazotisation and coupling. Its alternative name, Cochineal Red A, is misleading: it contains nothing derived from cochineal insects and is suitable for a vegan diet.

E 124 Ponceau 4r, cochineal red a
Ponceau 4R consists essentially of trisodium 2-hydroxy-1-(4-sulfonato-1-naphthylazo) naphthalene-6,8-disulfonate and subsidiary colouring matters together with sodium chloride and/or sodium sulphate as the principal uncoloured components. Ponceau 4R is manufactured by coupling diazotized naphthionic acid to G acid (2-naphthol-6,8- disulphonic acid) and converting the coupling product to the trisodium salt. Ponceau 4R is described as the sodium salt. The calcium and the potassium salt are also permitted.

The EU re-evaluation programme
Every additive authorised in the EU before 20 January 2009 was put back through EFSA by Commission Regulation (EU) No 257/2010, and this one is named in it. What the Regulation required is below; whether the opinion has since been published is not something this site records.
- Already re-evaluated when the programme began. Listed in Annex I as “Ponceau 4R, Cochineal Red A”, against the words “Re-evaluation completed on 23 September 2009”, and therefore not re-evaluated again under it.
Hazard reference values
The two committees set different figures. EFSA's acceptable daily intake is 0.7 mg/kg bw/day; JECFA's is 4 mg/kg bw/day (2011). 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.
| Type | Value | Population | Assessed by | Opinion |
|---|---|---|---|---|
| ADI | 4 mg/kg bw/day | — | JECFA | 2011 |
| ADI | 0.7 mg/kg bw/day | consumers | EFSA | not identified in the dataset |
Evidence and how bodies read it
Food additives and hyperactive behaviour in 3-year-old and 8/9-year-old children in the community: a randomised, double-blinded, placebo-controlled trial
- Design
- RCT
- Model
- human
- Dose
- Two mixtures of four synthetic colours plus sodium benzoate, at doses chosen to reflect typical UK intakes, given in a drink; challenge and placebo periods.
- Endpoint
- Global hyperactivity aggregate, combining teacher and parent ratings with a computerised attention test.
- Funding
- UK Food Standards Agency
What it found. Reported a small increase in the composite hyperactivity measure in 3-year-olds and 8/9-year-olds during the additive-challenge periods compared with placebo. The authors described the effects as modest and variable between individuals.
Limitations. The additives were given as mixtures, so the result cannot be attributed to any single colour or to the benzoate. Effect sizes were small relative to the spread between children, adherence differed between age groups, and the trial measured behaviour over short challenge periods rather than long-term outcomes.
How different bodies read the evidence
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 2015
In a refined exposure assessment carried out after the European Commission withdrew or reduced many maximum permitted levels for Ponceau 4R (E 124) from 2013, EFSA found that none of the exposure estimates exceeded the ADI of 0.7 mg/kg bw/day in any population group.
EFSA 2009
The ANS Panel re-evaluated Ponceau 4R (E 124) and, on the basis of kidney effects in a long-term mouse study (NOAEL 70 mg/kg bw/day), lowered the ADI from 4 to 0.7 mg/kg bw/day. It concluded that at maximum levels of use, intake estimates for high-consuming adults and for children aged 1–10 were generally above this ADI.
EFSA 2008
Judged the trial to provide limited evidence of a small effect on activity and attention in some children, but held that the mixtures tested did not allow any effect to be attributed to an individual additive, and that the findings did not warrant changing the acceptable daily intakes.
Action taken: Left intake limits unchanged
European Union (legislature) 2008
Took the same evidence as grounds for a consumer-information measure rather than a change in permitted levels, requiring foods containing these colours to carry the statement that they 'may have an adverse effect on activity and attention in children'.
Action taken: Imposed a mandatory warning statement while leaving the additives authorised
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 124?
- E 124 is Ponceau 4R (Cochineal red A). Ponceau 4R is a synthetic red azo dye used in confectionery, desserts and preserved meats. It is one of the six colours required to carry the activity-and-attention warning in the EU.
- What is Ponceau 4R (Cochineal red A) used for in food?
- It is listed as a colour — the role Codex and the EU assign it. This page shows every function each regulator records, with the citation for each.
- Where is Ponceau 4R (Cochineal red A) permitted?
- Of the seven regulators this site reads, Australia and New Zealand, 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 Ponceau 4R (Cochineal red A) vegan?
- Yes. Ponceau 4R (Cochineal red A) is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
