California’s Proposition 65 list, also referred to as the Safe Drinking Water and Toxic Enforcement Act of 1986, is used to allow Californians to make informed decisions about their exposure to hazardous chemicals which may cause health issues such as cancer, reproductive harm, or birth defects.
Effective as of March 19, 2021, the Office of Environmental Health Hazard Assessment (OEHHA) has added two chemicals to California’s Proposition 65 List: Molybdenum Trioxide and Indium Tin Oxide.
| Prop. 65 Chemical Name | CAS No. | Risk | Possible Applications |
| Molybdenum Trioxide | 1313-27-5 | Cancer | – Metal Additives – Pigments – Component of glass, ceramics, and enamels – Flame Retardant for Polyester (PET) and Polyvinyl Chloride (PVC) Plastic Resins Source: https://oehha.ca.gov/media/downloads/crnr/molydenumtrioxide.pdf |
| Indium Tin Oxide | 50926-11-9 | Cancer | – Glass and Plastic Screens – Flat-Panel Display (FPD) – Liquid Crystal Display (LCD) – Solar Panels Source: https://www.ncbi.nlm.nih.gov/books/NBK543202/pdf/Bookshelf_NBK543202.pdf |
The entire list of Prop. 65 substances are updated in Excel, XSV, and Pdf formats, on the California Office of Environmental Health Hazard Assessment (OEHHA) website.
Disclosure of hazardous chemicals is often accomplished using physical and/or online warning labels which are specific to the possible exposure.
Examples include:
– Consumer product exposure
– Environmental exposure
– Occupational exposure
If this sounds applicable to your situation, a risk assessment may be necessary to determine Prop. 65 substances that have to be declared.
