Application

Ammonium Persulfate is an off-white crystalline powder that serves as a potent oxidizing agent. It is used primarily as a bleaching agent in various industries, playing a crucial role in the production of metals, textiles, photographs, cellophane, and rubber. In the food industry, it is utilized at a concentration of up to 0.075% for bleaching food starch, often in combination with sulfur dioxide at up to 0.05%. Additionally, its application extends to hair care products, where it is used as a bleaching agent, although it may cause irritant dermatitis, contact urticaria, and allergic contact dermatitis, particularly among hairdressers.
