Description and Uses

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, contact urticaria and allergic contact dermatitis and represents a major allergen in hairdressers.

Ammonium Persulfate is a bleaching agent for food starch that is used up to 0.075% and with sulfur dioxide up to 0.05%.
