Product Testing and California Prop 65

Product Testing and California Prop 65

The California Safe Drinking Water and Toxic Enforcement Act of 1986, better known as California Prop 65, is a consumer “right-to-know law.”  Prop 65 requires companies wishing to sell products in California to warn consumers if any of the more than 800 chemicals listed in the act are in their products above a safe level. Laboratory testing of products can be required to determine if any of the chemicals are present above Prop 65’s safe harbor levels.  The list of chemicals contains both naturally occurring and synthetic chemicals that are known to cause cancer, birth defects, or other reproductive harm.

Merit is experienced in supporting California Prop 65 projects by providing analytical laboratory testing services on products for lead.  Consumer products tested by Merit span a diverse range, including toys, dinnerware, cups, food, pharmaceuticals, and even vacuum cleaner electrical cords. Merit has developed specific sample preparation procedures consisting of acidic dissolution of lead from the products with acetic acid.  The acid digested samples are then analyzed by ICP-MS. In addition to Prop 65, Merit also performs product testing to support other programs for inorganic and organic toxic chemicals, including Bisphenol A (BPA) and mercury. 

Merit’s team of experienced chemists provide chemistry consulting and testing to support manufacturers by providing problem solving, identification of  unknown constituents as well as contaminants, and verifying chemical content to be consistent with manufacturer’s claims.
