Proposition 65 is a law in the state of California that requires businesses and manufacturers to provide warnings about chemicals in their products that can cause cancer, birth defects or reproductive harm whether it is a naturally occurring or synthetic chemical. Our products with these labels contain very small amounts of any of these chemicals that are included in California’s annually published Prop 65 chemical list and would need to be ingested in large amounts to cause sickness.     -
