Overview
- The study, released Tuesday, applied nontargeted chemical analysis to 113 personal care and cleaning items and detected 3,141 chemical signals, with 303 compounds identified with confirmed, probable, or tentative confidence.
- Researchers found 98% of products contained at least one unlabeled chemical and 85% contained at least one unlabeled chemical with known or suspected health hazards, while the average product contained 51 detected chemicals versus 16 ingredients listed on labels.
- One in four products contained chemicals that directly contradicted packaging claims, including items labeled 'phthalate‑free,' '100% natural,' or 'hypoallergenic' that still contained phthalates, synthetic compounds, or known allergens.
- Authors said contaminants can be introduced through raw materials, processing equipment, packaging, supplier changes, or chemical reactions, and they rated more than half the products as 'fail' based on the concentration and hazard of undisclosed chemicals.
- The team plans to publish a full list of tested brands and items and recommends making nontargeted testing of finished, packaged goods a standard part of safety checks; there have been no specific regulatory actions reported in response to the study so far.
