Prop 65

What is Prop 65?

California Proposition 65 (Prop 65) is a consumer “right-to-know law”. Unless exempted, businesses may not expose individuals to a listed chemical without first giving a “clear and reasonable warning” (a Prop 65 warning), nor discharge a listed chemical into sources of drinking water. 

The Act lists more than 800 chemicals “known to the state to cause cancer, birth defects or other reproductive toxicity”. This list is updated at least annually. Prop 65 affects all consumer products sold or distributed in California, including textiles, footwear, hard goods, DIY products, toys, juvenile products, stationery, electrical/electronic items and more.
