What E129 actually is
Allura Red is the workhorse red of the food industry, known as Red 40 in the United States where it is the single most consumed colour additive. It replaced amaranth (Red 2) in the US in the 1970s and gives the red in everything from sports drinks to breakfast cereal.
What it is made from
Synthesised from petrochemical feedstock as an azo dye. Nothing plant or animal derived is involved, which is the main practical difference between it and carmine.
Vegan, vegetarian, and halal status
Allura Red is fully synthetic, so it is suitable for vegan, vegetarian, halal, and kosher diets. Shoppers avoiding carmine for religious or ethical reasons often find Red 40 used as the alternative.
Is E129 safe?
Permitted in the EU, UK, and US. EFSA set an acceptable daily intake of 7 mg per kg of body weight per day. Like tartrazine, it is one of the Southampton Six and any EU or UK product containing it must warn that it may have an adverse effect on activity and attention in children. The United States has taken a different path: California passed legislation restricting several dyes in school food, and the FDA has faced sustained petitions on synthetic colours, so the regulatory position is more active here than for most additives.
- Carries the mandatory EU and UK activity and attention warning
- Subject to active regulatory pressure in the United States, including state-level restrictions

Common questions
- Is Red 40 the same as E129?
- Yes. Red 40 is the US name, E129 is the European code, and Allura Red AC is the chemical name. Same substance.
- Is Red 40 bad for you?
- It is permitted by regulators with a set intake limit, but it is one of the six colours requiring an activity and attention warning in the EU and UK, and it is under active regulatory pressure in the United States.
- Is Red 40 halal and vegan?
- Yes. It is entirely synthetic. Shoppers avoiding carmine on religious grounds frequently end up with Red 40 as the alternative.
- Why do EU and US products look different?
- Because of the warning label. Many EU manufacturers reformulated to natural colours rather than carry the activity and attention statement, while US versions of the same brand often kept the synthetic dye.
- What are natural alternatives to Red 40?
- Beetroot red (E162), anthocyanins (E163) from berries, lycopene (E160d) from tomato, and paprika extract (E160c). Carmine (E120) is also used but is insect-derived.
