Lead/Cadmium in Talc and Other Baby Products


  • Challenge: A consumer products manufacturer received a California Proposition 65 complaint associated with the detection of lead and cadmium in talc and other baby products.  Because the need for a Proposition 65 warning is based on whether the lead or cadmium would pose a risk to the consumer, Cardno ChemRisk was asked to evaluate the potential for exposure to lead and cadmium in the products.
  • Approach: Cardno ChemRisk scientists conducted a risk assessment that evaluated the likelihood that trace amounts of lead and cadmium in talc and zinc oxide ointment in baby products might penetrate the skin and produce an absorbed dose in excess of the California Proposition 65 “safe harbour” concentration.
  • Findings: The products in question did not result in exposures to lead or cadmium in excess of the safe harbour concentrations and therefore did not pose a risk to the product users.
  • Value: The manufacturer successfully demonstrated compliance with the California regulation and also the low risk health risk associated with their products from trace impurities.
