Objective:

To identify unlabeled potentially harmful chemicals in personal care and cleaning products marketed as 'natural,' 'non-toxic,' and 'fragrance-free.'

Approach:
  • Chemical Testing Methodology: Nontargeted chemical testing was conducted using high-resolution two-dimensional gas chromatography time-of-flight mass spectrometry with machine learning–assisted identification.
Key Findings:
  • 98% of the 113 products tested contained at least 1 unlabeled potentially harmful chemical.
  • 85% contained at least 1 unlabeled chemical with known or suspected health hazards.
  • 58% of products failed contamination criteria.
  • An average of 51 detected chemicals were found per product, compared to 16 ingredients listed on labels.
  • 26% of products contained chemicals contradicting label claims, including products advertised as free of phthalates, parabens, fragrance, silicone, or oxybenzone.
Interpretation:

Label-based classifications did not reliably distinguish products that failed contamination testing.

Limitations:
  • The analysis evaluated chemical hazard rather than clinical risk.
  • It could not definitively establish the sources of individual contaminants.
  • The study did not account for exposure dose, route, or bioavailability.
  • Products were not selected to represent the broader market.
Conclusion:

COVID-19–related supply-chain disruptions may have influenced product composition.
