Prop 65 FAQ

1. What’s Prop 65?
The goal of Prop 65 is to help citizens make informed choices about things that may impact their health. Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm.  These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment. By requiring that this information be provided, Proposition 65 enables Californians to make informed decisions about their exposures to these chemicals. Proposition 65 also prohibits California businesses from knowingly discharging significant amounts of listed chemicals into sources of drinking water. Proposition 65 requires California to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm. This list, which must be updated at least once a year, has grown to include approximately 900 chemicals since it was first published in 1987. Proposition 65 became law in November 1986, when California voters approved it by a 63-37 percent margin.  The official name of Proposition 65 is the Safe Drinking Water and Toxic Enforcement Act of 1986.

2. What changed?
The warning section of the law was rewritten in an effort to make warnings more effective for consumer. This means that products that are exposed to specific chemicals now require clear and concise labeling.

3. Why does it matter?
Prop 65 requires products distributed in California to include specific warnings if they contain chemicals that cause Cancer or Reproductive Harm.

5. What kind of chemicals are prop 65 items tested for?
When the law first passed in 1986, there were only 30 chemicals that were specified under the law. Now, there are more than 900 chemicals specified. The list contains a wide range of naturally occurring and synthetic chemicals that include additives or ingredients in pesticides, common household products, food, drugs, dyes, or solvents. Listed chemicals may also be used in manufacturing and construction, or they may be byproducts of chemical processes, such as motor vehicle exhaust. The chemicals are those known to the State of California to cause cancer, birth defects, or reproductive harm.

7. Who administers Proposition 65? The Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program. OEHHA, which is part of the California Environmental Protection Agency (CalEPA), determines in many cases whether chemicals meet the scientific and legal requirements for placement on the Proposition 65 list, and administers regulations that govern warnings and other aspects of Proposition 65.
