New research highlights potential dangers from common cleaning chemicals known as quats.
Teddy Amenabar reports for The Washington Post.
In short:
- Scientists have found that quaternary ammonium compounds, or quats, may be toxic to brain cells known as oligodendrocytes. Dysfunction in these cells has been linked to several neurological conditions, including multiple sclerosis.
- These compounds are found in many disinfectants. Lab studies have found links with health issues like asthma and decreased fertility.
- Despite widespread use, the long-term effects of quats on human brain health remain unclear.
Key quote:
"We’re not looking to say that there’s a direct correlation between exposure and human neurodevelopmental issues. We don’t have that data yet. But we have fundamentally shown, very rigorously, that oligodendrocytes have a specific vulnerability to these chemicals.”
— Paul Tesar, director of the Institute for Glial Sciences at Case Western Reserve
Why this matters:
This research suggests that quats, common in disinfectants, could pose risks to brain health, emphasizing the need for cautious use and further study in light of potential neurological effects. You can reduce exposure by avoiding products that contain quats and instead using soap and water or cleaning products that contain safe alternatives.
