  • Patent number: 6461594
    Abstract: Tungsten and molybdenum oxide, and oxides of other metals and bronzes derived from such oxides, constitute a broad class of materials having applications as photochromic sunblock/cosmetics. These materials are well known in the prior art in the context of photochromic optical data storage media and they offer an excellent match with the very properties needed for cosmetic applications. The invention relates to the adaptation of the class of tungsten and molybdenum oxide photochromics to sunblocking/dosimetry, energy storage, and cosmetic coloration. In addition, certain naturally occurring proteins which exhibit the necessary photochromism can also be used alone for the same purpose or with the oxide systems described above.
