Independent lab finds 'troubling' levels of cancer-causing chemical in more types of dry shampoo products, report alleges

Key Facts

CNN — High levels of benzene, a cancer-causing chemical, have been detected in more brands and batches of dry shampoo products, according to a new report from Valisure, an independent laboratory.
Then on Monday, Valisure sent a citizen petition to the US Food and Drug Administration in which the lab described that among 148 batches from 34 different brands of dry shampoo products, 70% of samples tested showed “quantifiable” levels of benzene.
The petition urges the FDA to “expeditiously request recalls” on the affected batches of products containing benzene and better define limits for benzene contamination in other products.
In summary, three lots of dry shampoo products from one brand contained spray with more than 100 ppm of benzene, according to the petition, and some samples tested by Valisure showed more than 10 times the FDA drug limit.
