Used for poison ivy, insect bites, and minor skin irritation. Generally safe for intact skin. Main safety concern is phenol-containing formulations applied to large areas of broken/damaged skin — phenol is readily absorbed through compromised skin and is systemically toxic (CNS depression, cardiac arrhythmias). Zinc oxide is protective and non-toxic topically.","synthesis":{"derived_risk_level":"moderate","synthesis_confidence":0.82,"synthesis_method":"compound_composition","context_used":"human_adult","context_source":"product_users","exposure_modifier":1,"vulnerability_escalated":true,"escalation_reason":"Child exposure group","compounds_resolved":2,"compounds_total":2,"synthesis_date":"2026-03-27","synthesis_version":"1.0.0"},"hazard_summary":{"sensitive_populations":"child, infant","overall_risk":"low","primary_concerns":["Phenol toxicity if applied extensively to broken skin","Ingestion risk for children (pink liquid attractive)"],"exposure_routes":"dermal (primary), ingestion (children)"},"exposure":{"routes":["dermal"],"contact_types":["skin_direct"],"users":["adult","child"],"duration":"acute","frequency":"as_needed","scenarios":["Application to intact skin (poison ivy, bites) — safe","Application to extensive broken/blistered skin — phenol absorption risk","Child ingestion of pink liquid"],"notes":"Phenol absorption through intact skin is minimal.
