PCPC Challenges 2ppm Benzene Limit Cited By Valisure, Class Action Plaintiffs
Executive Summary
In comments to the US FDA, PCPC provides a “highly conservative” risk assessment of benzene impurity in a dry shampoo product, showing that “even a benzene concentration of 15 ppm in a hypothetical aerosol dry shampoo product would have an acceptable level of risk for a lifetime of daily use.” The exercise was undertaken in response to Valisure’s petition for FDA regulatory action on benzene-tainted dry shampoos.
