Microcrystalline Wax (E905C): What It Is and Is It Safe?
Microcrystalline wax is a refined petroleum-derived wax of fine crystalline structure used to glaze and coat confectionery, chewing gum, coffee beans and fresh fruit. It consists mainly of saturated mineral hydrocarbons (MOSH), which EFSA reports can accumulate in body tissues, though high-molecular-weight grades are poorly absorbed. The associated aromatic MOAH fraction is the focus of genotoxicity concern and is limited by purity specifications.
