What is Prop 65?
Prop 65 applies to any company operating in California, selling products in California, or
manufacturing products that may be sold in or brought into California. It mandates that the
Governor of California maintain and publish a list of chemicals known to cause cancer, birth
defects, and/or other reproductive harm. The list, which is updated annually, includes
hundreds of chemicals found in many everyday items. The purpose of Prop 65 is to inform
the public about exposure to these chemicals.
Prop 65 does not ban the sale of products containing these chemicals but instead requires
warnings on any product, product packaging, or literature with the product. Moreover, a Prop
65 warning does not mean that a product is in violation of any product safety standards or
requirements. In fact, the California government has clarified that a Prop 65 warning "is not
the same as a regulatory decision that a product is 'safe' or 'unsafe.'" Many of these
chemicals have been used in everyday products for years without documented harm. For
more information, go to https://oag.ca.gov/prop65/faqs-view-all.
A Prop 65 warning means that a company has either (1) evaluated the exposure and has
concluded that it exceeds the "no significant risk level"; or (2) has chosen to provide a
warning based on its understanding about the presence of a listed chemical without
attempting to evaluate the exposure.
Does this law apply everywhere?
Prop 65 warnings are required under California law only. These warnings are seen
throughout California in a wide range of settings, including but not limited to restaurants,
grocery stores, hotels, schools, and hospitals, and on a wide variety of products.
Additionally, some online and mail order retailers provide Prop 65 warnings on their
websites or in catalogs.
How do the California warnings compare to federal limits?
Prop 65 standards are often more stringent than federal and international standards. There
are various substances that require a Prop 65 warning at levels that are far lower than
federal action limits. For example, the Prop 65 standard for warnings for lead is 0.5 μg/day,
which is well below the federal and international standards.
