CI 77499 is a black iron oxide containing iron and oxygen and is used in cosmetics as a colorant. It is naturally available from the mineral magnetite, but for use in cosmetics it is synthetically made to filter out any impurities. In general, iron oxides are long-lasting, once applied they usually do not need to be reapplied. https://cosmetics.specialchem.com/inci-ingredients/ci-77499
