Mushbooh. Halal if vegetable-sourced stearic acid, haram if animal-derived

Why this verdict

E470b is magnesium salts of fatty acids (magnesium stearate), used as an emulsifier and anti-caking agent in supplements and powdered foods. SANHA classifies E470b as Mushbooh because the fatty-acid source must be verified. IFANCA and MUI classify it as Mushbooh: halal if vegetable-sourced, haram if animal tallow. The source is rarely disclosed on labels. Without that information the additive defaults to doubtful unless the product carries halal certification.
