Comments

Reports of skin sensitization in employees in tire and rubber industries; Not mutagenic in four strains of Salmonella and not clastogenic in mice bone marrow cells; Emergency treatment: "Paraphenylenediamine"; In sensitized individuals, paraphenylenediamine may cause allergic contact dermatitis following application as a hair dye and asthma following inhalation; Following ingestion, can cause angioneurotic edema, methemoglobinemia, acute tubular necrosis, and hepatotoxicity; An adult died after ingestion of 3 grams of p-phenylenediamine; Another adult who ingested 1800 mg developed angioneurotic edema and acute renal failure; [HSDB] A mild skin and eye irritant; May cause skin sensitization; [ICSC] May cause skin irritation and sensitization; [CAMEO] A mild skin and eye irritant; Likely a skin sensitizer based on animal studies and positive patch test results in volunteers exposed to rubber formulations; [CHEMINFO] See "p-Phenylenediamine."
