The material evolution of baby bottles represents one of the most significant consumer product safety transitions of the 2000s: polycarbonate (PC, BPA-based) was the industry standard until BPA research accumulated, leading to regulatory action and market shift to polypropylene (PP) and glass. Today, PP is the dominant material; glass and silicone are preferred alternatives. Nipples are separate from bottle bodies and typically made from silicone or latex.","synthesis":{"derived_risk_level":"low","synthesis_confidence":0.847,"synthesis_method":"compound_composition","context_used":"human_infant","context_source":"product_users","exposure_modifier":0.977,"vulnerability_escalated":true,"escalation_reason":"CHD tier product","compounds_resolved":6,"compounds_total":6,"synthesis_date":"2026-03-27","synthesis_version":"1.0.0"},"hazard_summary":{"sensitive_populations":"infants, children","overall_risk":"high","primary_concerns":["BPA leaches from PC baby bottles into formula and breast milk — accelerated by heat (warming formula), alkaline cleaning agents, and sterilization."],"exposure_routes":"direct oral ingestion"},"exposure":{"routes":["inhalation","oral"],"contact_types":["oral_direct"],"users":["infant"],"duration":"minutes","frequency":"daily","scenarios":["Incidental mouthing or hand-to-mouth transfer by children"],"notes":"Exposure is direct ingestion — formula or breast milk in contact with the bottle surface.
