Valisure Alerts US FDA To Benzene In Dry Shampoos, Says Any Detected Level Could Be ‘Unacceptable’

Valisure found 70% of 148 tested dry shampoo batches contained ‘quantifiable’ benzene. The US FDA advises a strict 2ppm limit when benzene’s use is unavoidable to produce a drug product with a “significant therapeutic advance.” In dry shampoos, “any significant detection of benzene could be deemed unacceptable,” Valisure suggests in its 31 October citizen petition to the agency.
