CA 65 Introduction
Proposition 65, the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted as a ballot initiative in November 1986. The Proposition was intended by its authors to protect California citizens and the State‘s drinking water sources from chemicals known to cause cancer, birth defects or other reproductive harm, and to inform citizens about exposures to such chemicals. so, in theory, all products containing hazardous substances within the scope of its control, including but not limited to Electrical and electronic products, textile products, toys, food contact materials, jewelry products and home decor products.
Proposition 65 requires the state to maintain and update a list of chemicals known to the state to cause cancer or reproductive toxicity. The latest California 65 control list is as below.
