FTC has fined multiple companies for labeling rayon as 'bamboo' (2009: fined Sears, Amazon, Leon Max, Macy's — $1.26M total). The viscose process dissolves cellulose in NaOH + CS2, regenerates fiber in acid bath — destroying all original bamboo properties. Final fabric has zero antimicrobial or eco-benefit of bamboo plant. TENCEL/Lyocell (closed-loop NMMO solvent) is the genuinely cleaner alternative. Modal is semi-closed-loop viscose.","synthesis":{"derived_risk_level":"severe","synthesis_confidence":0.88,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1.4,"vulnerability_escalated":false,"escalation_reason":null,"compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-03-27","synthesis_version":"1.0.0"},"hazard_summary":{"sensitive_populations":"viscose factory workers (CS2 neurotoxicity), environment near factories","overall_risk":"low","primary_concerns":["'Bamboo' fabric is almost always rayon/viscose (CS2 processed)","CS2 neurotoxicity and reproductive toxicity for factory workers","FTC enforcement: 'bamboo' labeling of rayon is illegal (fines issued)","Consumer pays eco-premium for product with no bamboo benefits"],"exposure_routes":"Consumer: negligible (finished garment).
