The initial focus of California Proposition 65 (Prop. 65) limits certain chemicals in California drinking water, but the scope has expanded to several areas, including environmental exposure, occupational exposure and consumer products.

Consumer products include electronic & electrical equipments, textile, hardgoods, toys & children items etc. Consumers have their rights to know, if hazardous toxic substances could be found in the products. Therefore, manufacturer should clearly state the toxic substances information on the products.

Some of the toxic substances are referred to as “No Significant Risk Level (NSRL)” for carcinogenic chemicals and “Maximum Allowable Dose Level (MADL)” for reproductive toxins. Products must have clear warning labels if the exposure concentrations exceed NSRL and MADL limits.

Limits for Prop. 65 listed chemical substances of consumer products vary by different products. Sometimes, it even does not define clearly for all chemicals and product types. For industrial practice, the limits are always referring to different court case settlements resulting from the challenges on products safety level. Settlement agreements as shown in below table require manufacturer to reformulate their products to significantly reduce toxic chemical levels (See Table 1).
