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.

INS 143 Fast Green FCF

Consists essentially of disodium 3-[ N -ethyl- N -[4-[[4-[ N - ethyl- N -(3- sulfobenzyl)amino]phenyl](4-hydroxy-2-sulfophenyl)methylene]-2,5-cyclohexadien-1-ylidene]ammoniomethyl]benzenesulfonate and its isomers together with subsidiary colouring matters, as well as sodium chloride and/or sodium sulfate as the principal uncoloured components. It is manufactured by condensing 2-formyl-5-hydroxybenzenesulfonic acid with a mixture of 3-[( N -ethyl- N -phenylamino)methyl]benzenesulfonic acid and its 2- and 4- isomers to form the leuco base precursor. Oxidation of the leuco base precursor with either chromium or manganese containing compounds produces the dye, which is purified and isolated as the disodium salt. May be converted to the corresponding aluminium lake in which case only the requirements in the General Specifications for Aluminium Lakes of Colouring Matters apply.

Evidence and how bodies read it

Studies, and the differing conclusions regulators drew from them, are curated rather than machine-read, and none has been written for this substance yet.

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 INS 143?
INS 143 is FD&C Green No. 3. FD&C Green No. 3, known internationally as Fast Green FCF, is a synthetic blue-green dye.
What is FD&C Green No. 3 used for in food?
It is listed as a colour — the role Canada, Codex and the US assign it. This page shows every function each regulator records, with the citation for each.
Is FD&C Green No. 3 banned in Europe?
No. FD&C Green No. 3 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 FD&C Green No. 3 permitted?
Of the seven regulators this site reads, Australia and New Zealand, Canada, Japan, South Korea, the US 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 FD&C Green No. 3 vegan?
Yes. FD&C Green No. 3 is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
