Silicates

E553 is the grouping for the silicate anti-caking agents — magnesium silicate (E553a) and talc (E553b) — mineral substances used to keep powdered and granulated foods free-flowing. As mineral compounds with no animal or alcoholic source, the silicates are halal. No recognised halal authority in our corpus publishes a separate ruling on the grouping code, but its constituents are standard minerals. E553 is halal.

On record from Codex Alimentarius — Umbrella code, see E553a, E553b for variant detail.
