Common personal care products widely contain unlabeled toxic chemicals, results from a new peer-reviewed study suggest. The testing of more than 110 items ranging from shampoo to baby lotions found evidence of unlabeled toxic chemicals in about 85%.

Many contained multiple ingredients known to be carcinogens or health hazards, and even 26% of products labeled “eco”, “green” or “natural” contained at least one dangerous compound. The products averaged more than three times as many chemicals than were listed on labels.

It is unclear whether the products are intentionally adulterated, or unintentionally contaminated. Either way, the findings raise further questions about the safety of everyday goods already under scrutiny for their health risks, and the authors say the study highlights the need for stricter oversight, including mandatory testing.
