CALIFORNIA 65

California Proposition No. 65 is the "Drinking Water Safety and Toxic Substance Enforcement Act of 1986", which was issued in November 1986. Its purpose is to protect California residents and the state’s drinking water sources so that they do not contain water sources that are known to cause cancer, Birth defects or other substances that are harmful to reproduction and development, and the residents should be informed truthfully when such substances appear in the product. The California List of 65 Controlled Substances was issued by OEHHA and updated quarterly. It was first published in 1987. Products sold to California must comply with California Act 65. 

The list is updated at least once a year, and more than 960 chemical substances are currently included in the substance list.

California 65 controls and evaluates whether specific products contain toxic substances based on similar product court cases. It is not recommended to test more than 960 chemical substances on the list one by one for a product, because it is almost impossible for a product to contain all the chemical substances listed in the list. The types of chemical substances and limit requirements for specific product control need to be based on the latest judgments of similar product cases. For example, if a company loses a lawsuit because a component of a product contains lead, a limit will be announced in the court, then this limit it will be used as the limit for lead content in the components of this type of product.

For different products, different materials, the controlled chemical substances are different, and the limit requirements are also different.

Some of the cases in California's Proposition 65 require the following table.
