What is Prop 65 Warning?

The official name of Proposition 65 is the Safe Drinking Water and Toxic Enforcement Act of 1986. This California law requires warnings to be provided to California consumers when they will be exposed to chemicals identified by California as causing cancer or reproductive toxicity. These warnings aim to help California consumers make informed decisions about the chemicals they may encounter when using products. The Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program and publishes a list of registered chemicals, which now exceeds 850. In August 2016, OEHHA adopted new regulations that took effect on August 30, 2018, modifying the information required in Proposition 65 warnings.

What is Proposition 65?

In 1986, California voters approved the Proposition 65 initiative in response to growing concerns about exposure to toxic chemicals. Officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, this law mandates California to publish a list of chemicals known to cause cancer or reproductive toxicity. Businesses with 10 or more employees must provide warnings when they intentionally cause significant exposure to listed chemicals.

The list currently includes over 900 chemicals. Proposition 65 does not ban or restrict the sale of chemicals on the list. These warnings are designed to help Californians make informed decisions about exposure to these chemicals when using products or visiting places.

OEHHA is responsible for administering the Proposition 65 program.
