Is it vegan? Additives & E-numbers E570
Is stearic acid vegan?
Quick answer: It depends. Stearic acid can come from animal fats such as tallow or from plant fats such as palm or shea; the label rarely says which.
Also called: E570, fatty acids, octadecanoic acid, stearate, magnesium stearate
The details
Stearic acid is a saturated fatty acid used in food (listed in the EU and UK under E570 “fatty acids”), chewing gum, supplements (as magnesium stearate), candles, soap and cosmetics.
PETA notes that, when animal-derived, it comes from fat from cows, pigs and sheep; the Vegetarian Resource Group says its source may be either animal or vegetable. Look for products stating a vegetable source or carrying a vegan logo.
