Scientists Discover Potential Harms of Quaternary Ammonium Compounds (QACs) in Disinfectants
Summary
New research is raising concerns that quaternary ammonium compounds, widely used in disinfectants and personal care products, may be linked to fertility problems, developmental defects and other health risks. Scientists say the chemicals are increasingly found in human tissues and blood, even as their use expanded during the pandemic.
Key Points
- Researchers say quaternary ammonium compounds (QACs) are widely used in disinfectants, sanitizers and many household products.
- Animal and lab studies have linked QAC exposure to fertility problems, birth defects, inflammation, respiratory issues and possible brain damage.
- Scientists found QACs in human blood, breast milk, urine and feces, and warn that frequent use may increase exposure risks.
- Experts say many situations only require soap and water, not routine disinfection with QAC-based products.
