A new study reveals how a common household chemical, widely used in cleaning products and personal care items, may disrupt biological processes in ways previously underestimated. Researchers found evidence suggesting the substance interferes with key cellular functions, raising concerns about long-term exposure risks even at low levels. The findings challenge existing safety assessments, which often rely on higher-dose testing, and could prompt re-evaluations of regulatory standards. Experts warn that further investigation is needed to clarify potential health impacts on vulnerable populations.
