Chemical structure of Sodium percarbonate, from PubChem compound 159762
Structure from PubChem CID 159762 (National Library of Medicine, public domain). A depiction of one compound: where a listing covers a family, or a substance has no single structure, this page shows none.

Sodium percarbonate releases hydrogen peroxide in water. JECFA specifies it as a component of the lactoperoxidase system used to preserve raw milk where refrigeration is not available, not as an additive to a finished food.

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.

United States—1 no quantity stated

No regulator sets a figure for Sodium percarbonate. That is not an absence of control: where the listing says quantum satis or good manufacturing practice, the quantity is limited to what the effect requires.

What it is made from

Made by reacting sodium carbonate with hydrogen peroxide. It is a powerful oxidant and is handled accordingly.

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.

FUNCTIONAL USES
Antimicrobial synergist (Component of lactoperoxidase/thiocyanate/peroxide antimicrobial raw milk preservation system)
METHOD OF ASSAY
Using a measuring cylinder, carefully add 100 ml of sulphuric acid solution (3.6 N) to a 600-ml beaker. Weigh accurately about 4 g of sample on to a tared watchglass. Let the weight of sample be W g. Place the watchglass in the beaker, cover the beaker with a clockglass and swirl to dissolve the sample. Transfer the solution to a 500 ml volumetric flask. Rinse the clockglass and the wall of the beaker with demineralised water and add all the washings to the volumetric flask. Dilute to volume with demineralised water and mix well. Immediately titrate a portion of this solution as follows: Add 100 ml of sulphuric acid solution (3.6 N) to a 600 ml conical flask and add potassium permanganate solution (0.1 N) dropwise to the appearance of a faint permanent pink colour. Using a safety pipette, add 25.0 ml of sample solution and mix well. Titrate with potassium permanganate solution (0.1 N) to the reappearance of the faint permanent pink colour. Let the titration obtained be A ml. Calculate the available oxygen content of the sample (as O 2 ) by the formula: where N = the normality of the potassium permanganate solution

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 Sodium percarbonate?
Sodium percarbonate releases hydrogen peroxide in water. JECFA specifies it as a component of the lactoperoxidase system used to preserve raw milk where refrigeration is not available, not as an additive to a finished food.
What is Sodium percarbonate used for in food?
It is listed as a preservative and an oxidising or reducing agent — the role the US assigns it. This page shows every function each regulator records, with the citation for each.
Is Sodium percarbonate banned in Europe?
No. Sodium percarbonate 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 Sodium percarbonate permitted?
Of the seven regulators this site reads, the US permits it. Each permission is for named foods at named levels, not a blanket one; the table on this page gives them with citations.
Is Sodium percarbonate vegan?
Yes. Sodium percarbonate is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
