Safer Consumer Products

We are working toward safer California households, workplaces, and products.

Authoritative Lists

The Candidate Chemicals identified in the Safer Consumer Products Regulations (California Code of Regulations, Title 22, Division 4.5, Chapter 55, Section 69502.2) were developed using 23 authoritative lists. The authoritative lists fall into two categories: lists based on hazard traits (15 lists), and lists based on potential exposure concerns (8 lists).

If you would like to view all the Candidate Chemicals associated with a specific authoritative list, please visit the CalSAFER Candidate Chemicals search page. Once on this webpage, use the “Advanced Search” filters to select the authoritative list of interest and then click “Update Results.” It is also possible to conduct a similar search including more than one authoritative list, as well as “Search Chemicals Unique to this Authoritative List”, using the Advanced Search filters. 

Please refer to CalSAFER for the current informational list.

Hazard Trait-Based Lists

Proposition 65 (Prop 65)

Chemicals known to cause cancer and/or reproductive toxicity that are listed under Health and Safety Code section 25249.8 of the California Safe Drinking Water and Toxic Enforcement Act of 1986 (22 CCR 69502.2(a)(1)(A)).

California’s Office of Environmental Health Hazard Assessment (OEHHA) publishes and updates the Prop 65 list. Officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, Prop 65 protects the state’s drinking water sources from being contaminated with chemicals known to cause cancer, birth defects, or other reproductive harm, and requires businesses to inform Californians about exposures to such chemicals.
