California Proposition 65

April 1, 2021 | Written by GreenSoft Technology, Inc.

Two Chemicals Added to California Proposition 65 Substances List

CA Prop 65 Now Includes Molybdenum and Indium Tin Oxide

prop-65California’s Office of Environmental Health Hazard Assessment (OEHHA) has updated the list of substances regulated under the state’s Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).

Effective March 19, 2021, the following two substances have been added to the list of chemicals known to the State of California to cause cancer:

  • Molybdenum Trioxide (CAS No. 1313-27-5)
  • Indium Tin Oxide (CAS No. 50926-11-9)

Molybdenum trioxide is used to manufacture molybdenum metal, which serves as an additive to steel and corrosion-resistant alloys.

Indium Tin Oxide (ITO) is an optoelectronic material that is widely used across multiple industries, including but not limited the following common applications:

  • Aircraft windshield defrosting films
  • Antireflection coatings
  • Architectural windows
  • Bragg reflectors for VCSEL lasers
  • Electronic ink applications
  • Electrowetting on dielectrics
  • Flat-panel displays
  • Gas sensors
  • Glass doors of supermarket freezers
  • Infrared-reflecting coatings
  • IR reflectors for low-e window panes
  • Liquid crystal displays
  • OLED displays
  • Optical coatings
  • Plasma displays
  • Polymer-based electronics
  • Smart windows
  • Sodium vapor lamp glasses
  • Thin film photovoltaics
  • Thin film strain gauges in gas turbines, jet engines, and rocket engines
  • Touch panels
  • Transparent conductive coatings

OEHHA’s notice about the two substance additions can be found online.

Affected companies are required to inform Californians about exposure to substances on the CA Prop 65 chemicals list, either through their products or at their business locations, before the potential exposure takes place. Penalties for being found in violation of CA Prop 65 can be as high as $2,500 per violation (per exposed person), per day.
