What is E472a?
An emulsifier made by combining two other approved additives, acetic acid and mono-/diglycerides, used to keep fats and water blended smoothly in baked goods and desserts.
E472a (acetic and fatty acid esters of glycerol) is an emulsifier made by combining acetic acid with mono- and diglycerides of fatty acids. Regulators consider it thoroughly reviewed and low-risk, since it's broken down in the body into its two starting ingredients, both already independently assessed as safe. Goodnessly rates it Safe.

What is E472a?
E472a is made by chemically combining mono- and diglycerides of fatty acids (E471) with acetic acid (E260, the acid in vinegar) — a process called esterification. The result is an emulsifier, often abbreviated ACETEM, that's particularly good at helping fat and water-based ingredients stay blended without separating. The fatty-acid raw material is usually derived from soybean oil, though it can come from other plant oils or, less commonly, animal fats.
What's it used for?
- Emulsifying fat and water in baked goods, cakes and biscuits
- Improving texture and shelf life in margarine and spreads
- Stabilising fillings and cream-based desserts
- Helping dried products like milk powder and instant mash redissolve smoothly
- Preventing packaged pasta and rice from sticking together
Where you'll find 472a on the shelf
Mostly in baked goods and other products that mix fat with water-based ingredients.
Is E472a safe? What the research says
Because E472a is built from two already-approved ingredients, regulators have generally treated it as low-risk — though the underlying review process is worth understanding.
| Region | Status | What this means |
|---|---|---|
| AU/NZ Australia & New Zealand (FSANZ) | Permitted | Permitted as an emulsifier with no specific quantity restriction in most food categories. |
| EU European Union (EFSA) | Permitted, no ADI | Listed as E472a. EFSA's 2020 re-evaluation concluded no numerical Acceptable Daily Intake was needed, on the basis that it's extensively broken down in the gut into acetic acid and mono-/diglycerides, both normal dietary constituents already assessed as safe on their own. |
| US United States (FDA) | GRAS | Holds Generally Recognized As Safe status for use as an emulsifier. |
EFSA's review noted that one toxicology study had found some tissue changes in test animals, but the panel judged that particular study unreliable and didn't factor it into the overall safety conclusion — worth knowing, even though it didn't change the outcome.
- 2020 EFSA group re-evaluation: E472a was reviewed alongside the related E472b–f family (lactic, citric and tartaric acid esters), all found to carry no safety concern at reported use levels. No further changes have followed since.
This section is checked periodically rather than continuously — if you're reading this well after the date above, it's worth confirming nothing has changed before citing it.
Who this matters to
- Strict vegans and vegetarians — the fatty-acid raw material is usually plant-derived (typically soybean oil), but can occasionally come from animal fat, and this isn't always distinguishable from the label alone
- Anyone avoiding genetically modified ingredients, since soybean oil is a common raw material and is frequently GM-derived
- Otherwise, no population group has a specific safety-based reason to limit E472a
Goodnessly rates E472a Safe. The main open question for most people is sourcing (plant vs animal, GM vs non-GM) rather than toxicological safety, which regulators consider well established.
How to spot it on a label
E472a is usually declared by its full chemical name or E number. Look out for:
- Acetic acid esters of mono- and diglycerides of fatty acids
- ACETEM
- 472a or E472a
- "Emulsifier (472a)" in the ingredients list
Baked goods, margarine and dried convenience products are the most common places to find it.

Frequently asked questions
Is E472a the same as ACETEM?
Yes — 472a (or E472a) is the additive code for acetic acid esters of mono- and diglycerides of fatty acids, commonly abbreviated ACETEM in industry documentation.
What is E472a made from?
It's made by combining mono- and diglycerides of fatty acids (E471) with acetic acid (E260, the acid in vinegar) through a chemical process called esterification. The fatty-acid component is usually derived from soybean oil, though other plant oils or animal fats can also be used.
Is E472a vegan?
Usually, but not always. Most commercial E472a is made from plant oils, typically soybean, but it can occasionally be derived from animal fat. The label alone won't tell you which, so strict vegans may want to check with the manufacturer if it matters to them.
Does Goodnessly rate E472a as safe, caution, or avoid?
Goodnessly rates E472a (Acetic Acid Esters of Glycerol) as Safe. EFSA's 2020 re-evaluation found no need for a formal Acceptable Daily Intake, concluding it's broken down in the body into its two starting ingredients, both already independently reviewed as safe.
Is E472a gluten-free?
Yes. E472a is not derived from gluten-containing grains and is considered gluten-free.
