The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) intends to list the following chemicals as known to the state to cause cancer under the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65): Molybdenum trioxide (CAS No. 1313-27-5) Indium tin oxide (CAS No. 50926-11-9) Molybdenum trioxide has widespread industrial use. Its major use is as an additive to steel and other corrosion-resistent alloys. It is also used in the production of molybdenum products, as an industrial catalyst, a pigment, a crop nutrient, a component of glass, ceramics and enamels, a flame retardant for polyester and polyvinyl chloride resins, and as a chemical reagent. Indium tin oxide is primarily used as a thin coating on glass or plastics used for touch panels (electrochromic, eletroluminescent, and LCDs), plasma displays, flat panel displays (TV, computer screens, cell phones, etc), field emission displays, heat reflective coatings, solar panels, cathode-ray tubes, energy efficient windows, gas sensors, etc. This action is being proposed pursuant to the “Labor Code” listing mechanism. OEHHA has determined that each of these substances meets the criteria for listing by this mechanism.
