Abstract (en)
[origin: EP1813441A1] The cosmetic article comprises component formed using magnesium material. The inorganic protective layer is chemically bonded to the component. The protective layer containing metal chosen from groups of III, IV, V, VI, Ib, IVb, Vb, VIb, VIIb and VIIIb and their oxide, ceramic, nitride, carbide, silicide and/or boride. The component is a sharpener (1), a ruler or a cosmetic container. The protective layer further contains metal chosen from aluminum, tin, vanadium, chromium, molybdenum, zirconium, hafnium, titanium, iron, tungsten, platinum, copper, silver and gold and their oxide, ceramic, nitride, carbide, silicide and/or boride. The protective layer has at least one layer containing metal nitride, metal carbide, metal silicide and/or metal boride. The metal nitride layer is a nitrided metal layer chosen from nitrided chromium layer, nitrided iron layer, nitrided molybdenum layer and nitrided tungsten layer. The metal boride layer is a boron compound deposited on the magnesium material. The protective layer containing metal oxide is a mixed metal oxide which contains colored mixed oxide. The colored mixed oxide consists of titanium oxide, vanadium oxide, zirconium oxide, niobium oxide and/or tantalum oxide.
