The active antimicrobial compounds are predominantly quaternary ammonium compounds (QACs) — benzalkonium chloride (BAC), didecyldimethylammonium chloride (DDAC), and related structures. QACs have emerged as a significant concern: they are respiratory sensitizers, cytotoxic at low concentrations, suspected reproductive toxicants, and are accumulating in indoor environments and human bodies from high-frequency use. COVID-era use patterns dramatically increased QAC exposure across populations.","synthesis":{"derived_risk_level":"high","synthesis_confidence":0.5,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1.173,"vulnerability_escalated":true,"escalation_reason":"Child exposure group","compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
