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.

How JECFA defines it
The international specification for identity and purity, prepared by the Joint FAO/WHO Expert Committee on Food Additives and published by FAO. It is a different document from any above, written by a different body and revised on its own cycle; it is advisory, and a country adopts it or does not.

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 Isopropyl alcohol?
- Isopropyl alcohol is an extraction solvent and processing aid, used to obtain spice oleoresins, hops extract and lemon oil.
- What is Isopropyl alcohol used for in food?
- It is listed as a solvent — the role Canada and the US assign it. This page shows every function each regulator records, with the citation for each.
- Is Isopropyl alcohol banned in Europe?
- No. Isopropyl alcohol does not appear on the EU's list of authorised food additives, which is not the same as being banned: the EU permits an additive only where it has authorised it, and usually the reason for an absence is that no one applied. The EU has made no finding against this substance. It does mean it may not be used as a food additive in the EU today.
- Where is Isopropyl alcohol permitted?
- Of the seven regulators this site reads, Australia and New Zealand, Canada, Japan, South Korea and the US 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 Isopropyl alcohol vegan?
- Yes. Isopropyl alcohol is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
