Concerns span both product types: (1) liquid detergents containing ethoxylated surfactants (SLES, PEG compounds) contaminated with 1,4-dioxane — the same contamination concern as shampoo but with whole-load textile processing; (2) dryer sheets and liquid fabric softeners containing quaternary ammonium compounds and synthetic fragrance that aerosolize through dryer exhaust and remain on fabric against skin; (3) optical brighteners — fluorescent whitening agents that absorb UV and emit visible light — which remain on fabric and have mild estrogenic activity. The dryer exhaust from scented laundry products has been documented to emit VOCs and particulates equivalent to a secondary emission source.","synthesis":{"derived_risk_level":"moderate_to_high","synthesis_confidence":0.715,"synthesis_method":"compound_composition","context_used":"human_infant","context_source":"product_users","exposure_modifier":1.4,"vulnerability_escalated":true,"escalation_reason":"Infant exposure group","compounds_resolved":3,"compounds_total":3,"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]).
