Superabsorbent polymer (SAP, sodium polyacrylate): absorbs 200-300x its weight in water — generally safe but creates alkaline microenvironment that disrupts skin pH (healthy skin pH 4.5-5.5, urine raises to 6-8). Fragrance: many products contain synthetic fragrance — contact sensitizer on compromised skin. Incontinence-associated dermatitis (IAD): affects 5.6-50% of incontinent elderly — exacerbated by occlusion, alkaline pH, and chemical irritants. Zinc oxide barrier cream: standard prevention for IAD.","synthesis":{"derived_risk_level":"moderate_to_high","synthesis_confidence":0.82,"synthesis_method":"compound_composition","context_used":"human_adult","context_source":"product_users","exposure_modifier":1.4,"vulnerability_escalated":false,"escalation_reason":null,"compounds_resolved":2,"compounds_total":2,"synthesis_date":"2026-03-27","synthesis_version":"1.0.0"},"hazard_summary":{"sensitive_populations":"incontinent elderly with fragile skin, IAD-affected individuals","overall_risk":"low","primary_concerns":["IAD affects 5.6-50% of incontinent elderly (skin breakdown from occlusion)","Fragrance chemicals on compromised skin (contact sensitizer)","Alkaline pH microenvironment from urine disrupts skin barrier","Adhesive tabs cause skin tears on elderly paper-thin skin"],"exposure_routes":"Dermal (continuous occlusive contact with product materials, urine, fragrance)"},"exposure":{"routes":["dermal"],"contact_types":["skin_prolonged"],"users":["adult"],"duration":"continuous","frequency":"daily","scenarios":["24/7 occlusive contact with SAP against fragile elderly skin","Fragrance chemical contact on skin already compromised by IAD","Alkaline pH from urine + SAP environment disrupting skin barrier","Adhesive tape on product causing skin tears in elderly (paper-thin skin)"],"notes":"IAD prevalence: 5.6-50% of incontinent elderly in institutional settings (Beeckman et al. 2015 systematic review).

Fragrance-free products: Prevail, Tranquility, some Depend and Tena lines — check label. pH-buffered products: newer formulations add citric acid to maintain acidic skin pH.
