Is E570 (Stearic acid / Fatty acids) Halal?

Our assessment

Doubtful — depends on source

E570 (Stearic acid / fatty acids) is a fatty acid that can be animal- or plant-derived — so it is treated as doubtful (mushbooh) unless the source is known.

Also known asStearic acidFatty acidsOctadecanoic acid

What is E570?

Stearic acid is a fatty acid used as an emulsifier, anti-caking agent and glazing agent in foods, and widely in supplements, tablets and cosmetics. It can be obtained from vegetable oils or from animal fats.

Obtained by splitting fats and oils into their fatty acids. The feedstock can be vegetable (e.g. palm) or animal (tallow) — the label rarely says which.

Why is it doubtful (mushbooh)?

Stearic acid is doubtful because it can be plant- or animal-derived, and the source is usually unstated. Plant-derived stearic acid is halal; animal-fat stearic acid is only permissible if from a halal animal. Verify before assuming — much commercial stearic acid is palm-derived, but this should be confirmed.

How to verify a product in Singapore

  1. Ingredient-level guidance is not halal certification — check the complete product, not just this ingredient.
  2. Look for recognised halal certification, and check the finished product on the official MUIS HalalSG register.
  3. When the source or processing aids are unclear, contact the manufacturer.

In Singapore, verify the finished product on the MUIS HalalSG register or contact the manufacturer, since the fat source is usually not printed on the label.
