These products are applied to floor and furniture surfaces that represent large-area skin contact environments — particularly for infants and toddlers who spend extensive time on floors. The primary chemical concerns are glycol ether solvents (particularly 2-butoxyethanol / EGBE, a reproductive toxicant), volatile organic compound loads in enclosed indoor spaces during and after application, fragrance sensitization, and residues left in carpet pile after cleaning that contact skin long after application. Professional carpet cleaning with perchloroethylene (PERC) or dry-cleaning solvents represents a distinct high-exposure scenario.","synthesis":{"derived_risk_level":"severe","synthesis_confidence":0.757,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1.02,"vulnerability_escalated":false,"escalation_reason":null,"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]).
