A hardener and anticaking agent that can come from plants or animal fat
E570 (fatty acids, most often stearic acid) is doubtful (mushbooh). Stearic acid is found in animal and vegetable fats alike. Commercially it can be obtained from either, and the finished additive is the same white waxy substance. The label does not tell you which fat it came from.
The reference entry on stearic acid says it is generally more concentrated in animal fat, though cocoa butter and shea butter are plant exceptions. A British kosher guide also lists stearic acid among the additives that need rabbinical approval because it is "found in all animal fats and vegetable oils".
E570 covers fatty acids as a food additive, and stearic acid (a saturated fatty acid with 18 carbon atoms) is the most common member. In food it acts as a hardener, a glazing and anticaking aid and a processing agent. The reference entry on stearic acid lists uses in baked goods, frozen dairy products, gelatins, puddings, hard candy and non-alcoholic beverages. It also acts as a hardener in candies, typically combined with sugar or corn syrup. Outside food it is widely used in candles, soaps and cosmetics.
The reference notes that the European Food Safety Authority re-evaluated fatty acids as a food additive in 2017; we mention this only to show that E570 is regularly reviewed for safety. It is a safety review, not a halal ruling.
The reference says that stearic acid is obtained commercially by saponifying fats and oils with hot water (around 100 °C) and then distilling the resulting mixture. The commercial product is often a mixture of stearic and palmitic acids, though purified forms exist. Oleic acid from palm and soy oils can also be hydrogenated to produce it. Hydrogenation of plant oils means a plant route to the same chemical is easy, which is why many vegan-certified products contain stearic acid.
It also says stearic acid occurs in both animal and vegetable fats, and is generally more concentrated in animal fat, reaching up to 33 per cent in beef liver while vegetable fats typically contain less than 5 per cent. Cocoa butter (about 34 per cent) and shea butter (28 to 45 per cent as a triglyceride) are the main plant exceptions. The takeaway is that the same name covers products from very different sources.
Because of the double source. Plant stearic acid, from palm, soy, cocoa butter or shea, raises no halal concern. Animal stearic acid, from beef tallow or lard, raises the question of which animal and whether it was slaughtered in the halal way. Pork fat would make it forbidden.
As with other fat derivatives, some scholars point to chemical transformation (istihalah) and argue that stearic acid is a different substance from the fat it was made from. Others disagree, or require that the starting material be halal. We do not pick a side. If you follow a particular scholar, follow their view; if you are cautious, choose a product with a halal or vegan mark.
| Product | Comment |
|---|---|
| Hard candy and sweets | Hardener; check label for other animal ingredients such as gelatine |
| Baked goods and puddings | Texture and release |
| Chewing gum | Gum base ingredient; check for halal mark |
| Tablets and supplements | Magnesium stearate and stearic acid are common tablet lubricants |
In tablets, you may see "magnesium stearate", which is the magnesium salt of stearic acid. The same source question applies.
Salts of fatty acids (E470a, E470b) and mono- and diglycerides (E471) are made from the same kinds of fatty acids. When a label lists several of these, they all share the plant-or-animal question and a single piece of information, such as a halal mark or a vegan mark, answers it for all of them at once.
Plant-derived E570 is vegan. Animal-derived E570 is not. The British kosher guide treats stearic acid as needing rabbinical approval because of its possible animal source. A kosher mark is not the same as halal certification.
A short, polite email usually gets a useful reply. You can copy and adapt this:
Keep the reply. If the answer is vague, treat the product as doubtful and choose a certified alternative.
Islamic teaching on doubtful matters is the basis for how we label these ingredients. A well-known hadith, recorded in the collections of al-Bukhari and Muslim, says that the halal is clear and the haram is clear, and between them are doubtful matters that many people do not know about. Scholars generally draw two practical points from it. First, you are encouraged to avoid what you have real reason to doubt, as far as you reasonably can. Second, this is not a call to be anxious about every additive: where there is no real reason to doubt, most scholars do not ask you to investigate beyond what is reasonable.
That is why our "doubtful" label means check if you can, not assume it is forbidden. A halal logo, a clear source on the label, or a short email to the maker will usually settle the matter. If you follow a particular madhab or scholar, their guidance comes first.

It is doubtful. Stearic acid occurs in both animal and vegetable fats, and the label does not say which one was used.
No. It can also be made from plant oils, for example by hydrogenating oleic acid from palm and soy oils, and it occurs in cocoa butter and shea butter.
It is the magnesium salt of stearic acid, so the same source question applies. Look for a halal or vegan mark on the product.
Only if it is plant derived. A vegan mark is the best guide.
Cocoa butter naturally contains stearic acid, but that is part of the chocolate itself and not the additive. Check the label for an added E570.
