The detail

Stearic acid sits at the root of a family of doubtful additives: its salts and esters become magnesium stearate (E572), sodium stearate, and the stearate emulsifiers E481/E482. HalalExpo's checker records plant-derived stearic acid as the halal industry standard, porcine as haram, and unspecified as requiring source documentation. MuslimConsumerGroup states the same condition. IFANCA lists stearic acid among doubtful ingredients in candy and gum.
