Designated food additive: Standards and Specifications for Food Additives, Part III, 2. 가공보조제 (processing aids), 스테아린산 (“Stearic Acid”, the English the Code prints beside it). Main use (주용도) of 스테아린산: 제조용제. Standard for use (사용기준) of 스테아린산: (1) [to be used under the general standard for use in II. 2. 1), the minimum amount that achieves the technical effect, with no limit set for this additive in particular] “II. 2. 1)의 규정에 따라 사용하여야 한다.” The Korean is the standard as published. There is no official English translation of the current Code (the English version on MFDS’s website is the 2020 edition and has no legal effect); the English in square brackets is this site’s description of what each sentence does, not a translation of the foods or the levels. Compositional specifications (Part IV) are not imported, nor are the general standards in Part II, which apply to every additive.

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.

Australia and New Zealand—54 GMP
Canada—4 GMP
South Korea—1 no quantity stated
United States—1 no quantity stated

No regulator sets a figure for Stearic acid. 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

Obtained by splitting fats and oils. Vegetable fats such as palm oil and animal tallow are both used, and the finished acid is chemically identical either way — so the label cannot tell you which it was.

  • Vegan status depends on the source
  • Vegetarian status depends on the source
  • May raise a halal question
  • May raise a kosher question

This is not an omission. What this additive is made from is not fixed — depending on the manufacturer it may be plant, animal or microbial in origin, nobody is required to say which, and the same product can change source between production runs. Ask the manufacturer if it matters to you; a label cannot answer it.

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 Stearic acid?
Stearic acid is a fatty acid used as a lubricant, release agent and flavouring, and as the starting point for a range of other additives.
What is Stearic acid used for in food?
It is listed as a lubricant or release agent — the role Canada and the US assign it. This page shows every function each regulator records, with the citation for each.
Is Stearic acid banned in Europe?
No. Stearic acid 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 Stearic acid permitted?
Of the seven regulators this site reads, Australia and New Zealand, Canada, 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 Stearic acid vegan?
It depends on the source, and a label will not tell you. Stearic acid can be made from plant or animal material, manufacturers are not obliged to say which, and the same product can change between production runs. Anyone who needs to know has to ask the manufacturer.
