Cera Microcristallina
Microcrystalline wax is FDA-permitted for direct food use under 21 CFR 172.886 (specific purity specifications) and as a chewing-gum base ingredient. EFSA evaluated microcrystalline waxes (E905) and concluded they are safe at typical use levels.
What it is
Cera microcristallina (microcrystalline wax) — a refined high-molecular-weight petroleum wax composed of saturated branched and cyclic hydrocarbons.
Food coating / chewing gum base / cosmetic structuring agent.
Why it's flagged
- aromatic hydrocarbon impurities if poorly refined (regulatory specs limit these)
What regulators actually say
