What is California Regulation 65 in U.S. SDS?

Posted Date:2023/9/22

California Proposition 65 (also known as the Drinking Water Safety and Toxic Enforcement Act of 1986) was enacted in November 1986 to protect the residents of California and the state's drinking water sources from substances known to cause cancer, birth defects, or other reproductive hazards, and to notify residents when such substances are present.

There are two main requirements:

(a) No person shall intentionally discharge or release a chemical substance known to the State to be carcinogenic or reproductively toxic, resulting in pollution of water or land;

(b) No person shall knowingly and intentionally expose any person to a chemical known to the State to cause cancer or reproductive toxicity without first giving clear and reasonable warning.

The California Proposition 65 list is a list of chemicals in California known to cause cancer or reproductive toxicity. There are more than 950 substances in the list. The list is updated annually.

California uses safe concentrations (exposure levels required for trigger warnings) for many of the listed chemicals. Exposure below these levels does not require a warning. For example, on the list. Jewelry is just one of many products that may contain lead. Manufacturers and importers of jewellery containing lead must warn consumers if the amount of lead they accept in jewellery exceeds the safe concentration level of 0.5 micrograms per day.

How do I determine if a product requires a Proposition 65 warning?

California Proposition 65 applies only to exposure to listed chemicals. It does not prohibit or restrict the use of any given chemical by setting concentration limits for the chemical in the product. The concentration of the listed chemical in a product is only one factor to consider when calculating its exposure level. Exposure levels are compared to safe concentration levels to determine if a warning is needed.

Are products with Proposition 65 warnings safe?

Proposition 65 is intended to inform consumers that they are being exposed to chemicals known to cause cancer and/or reproductive toxicity. Consumers can decide for themselves whether they want to buy or use the product. A Proposition 65 warning does not necessarily indicate that a product violates any product safety standard or requirement.

Since the California Act 65 of the United States relates to health issues in the United States, it is necessary to list whether the product contains relevant harmful substances in part 15 of the SDS, that is, the section of "Regulatory information". Therefore, it also says that if the product contains relevant harmful substances, it does not mean that the product is unsafe.
