Contact allergens
Persulfates are strong oxidizing agents widely used in the production of metals, textiles, photographs, cellophane, rubber, adhesive papers, foods, soaps, detergents, and hair bleaches. Ammonium persulfate is used as a hair bleaching agent. It may induce irritant dermatitis, (mainly) nonimmunologic contact urticaria, and allergic contact dermatitis and represents a major allergen in hairdressers. People reacting to ammonium persulfate also react to other persulfates such as potassium persulfate.

Safety Profile
Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion. A powerful oxidizer that can react vigorously with reducing agents. Releases oxygen when heated. Mxtures with sodium peroxide are explosives sensitive to friction, heating above 75℃, or contact with CO2 or water. Mixtures with (powdered aluminum + water) or (zinc + ammonia) are explosive. Violent reaction with iron or solutions of ammonia + silver salts. Solution with sulfuric acid is a strong oxidzing cleaning solution. When heated to decomposition it emits toxic fumes of SO,, NH3, and NOx.
