UK FSA front of pack threshold

Three separate readings, kept apart on purpose. This is not a score, and none of it says this product is harmful.

This label lists 2 emulsifiers, 2 thickeners and gelling agents, 1 antioxidant, 1 colour, 1 flour treatment agent and 1 preservative.

E466 Carboxymethyl cellulose
Thickener and stabiliser
Low limited evidence

What it is. A modified plant fibre used to thicken and stabilise.

Why it is used. Common in ice cream, low fat products, gluten free bakery and sauces.

What the evidence says. Falls in the same emulsifier and gut research bucket as polysorbate 80, with early human work hinting at effects on the microbiome. Interesting, not conclusive.

Regulatory status UK Permitted EU Permitted US Permitted

Permitted with limits.

Assessed against EFSA. Full entry for E466

E471 Mono- and diglycerides of fatty acids
Emulsifier
Low limited evidence

What it is. Fat derived emulsifiers, closely related to ordinary dietary fats.

Why it is used. One of the most used additives in food: bread, margarine, ice cream, cakes and sauces.

What the evidence says. The body handles these much as it handles other fats, and EFSA's re-evaluation raised no safety concern at the levels used. They sit in the same broad emulsifier and gut microbiome research question as the others, which remains unsettled.

Regulatory status UK Permitted EU Permitted US Permitted

Permitted without a numerical limit. The fat source is not always stated, which matters for some diets rather than for safety.

Assessed against EFSA. Full entry for E471

E300 Ascorbic acid (vitamin C)
Antioxidant
No real concern strong evidence

What it is. Vitamin C, added to protect colour and flavour and sometimes to fortify.

Why it is used. Stops browning in juices and cut fruit, protects fats, and boosts vitamin content.

What the evidence says. Beneficial and harmless at the levels used. Included here as a reminder that an E number is just a code, and plenty of them are ordinary nutrients.

Regulatory status UK Permitted EU Permitted US Permitted

Permitted freely, no concern.

Assessed against EFSA, JECFA. Full entry for E300

E415 Xanthan gum
Thickener and stabiliser
No real concern strong evidence

What it is. A fibre made by fermenting sugars with a bacterium, which thickens liquids at very low doses.

Why it is used. Thickens sauces and dressings and gives structure to gluten free baking.

What the evidence says. Passes through largely undigested and is treated as safe by regulators, with no numerical intake limit. Very large amounts act as fibre does, which is a digestive effect rather than a safety one.

Regulatory status UK Permitted EU Permitted US Permitted

Permitted freely.

Names and jobs come from the register of additives permitted in Great Britain, which we have not finished transcribing: a code shown without a name is a gap in our coverage, not a finding that it is unapproved. Naming one is not grading it either. Full detail appears only where we have an assessment against a named authority, so all of this describes our coverage rather than these additives. Most are common and low concern.

As printed on the pack, in the producer's own order: ingredients are listed by weight, so what comes first is most of what is in it. E numbers link to their assessment where we have one.
