For Businesses
Proposition 65 requires the State of California to maintain and update a list of chemicals that can cause cancer, birth defects or other reproductive harm. Businesses with 10 or more employees that expose individuals to listed chemicals through their products or operations generally must provide warnings.
This section of the website provides information to assist businesses with Proposition 65 compliance.

In order to provide information to the public regarding exposures to listed chemicals, OEHHA may request information from businesses pursuant to Title 27, California Code of Regulations, Article 2, section 25205(b). The information provided by a business under Section 25205(b) is not a substitute for a “clear and reasonable” warning required by Health and Safety Code section 25249.6 (“The Act”). At the same time, the failure of a business to provide information requested by OEHHA under Section 25205(b) is not a failure to provide a clear and reasonable warning in violation of the Act.
