Comments

"Ammonium persulfate, used to 'boost' peroxide hair bleaches, causes contact urticaria and anaphylactoid reactions." [Marks, p. 177] Both ammonium persulfate and benzoyl peroxide are used to bleach flour. [Marks, p. 324] Used as a reducer and retarder in the development of photographs; [Kanerva, p. 1637] It may induce either Type I reactions (urticaria, anaphylaxis, and asthma) or Type IV reactions (allergic contact dermatitis). [Kanerva, p. 1513] A skin, eye, and respiratory tract irritant; A skin sensitizer; May cause urticaria and asthma; [ICSC] Frequent skin rashes are reported in workers exposed to persulfates (S2O8). Rats inhaling 4-20 mg/m3 of ammonium persulfate 23.5 hours/day for 7 days show signs of lung inflammation and loss of body weight. The TLV is proposed to reduce irritation of skin, throat, and respiratory tract. [ACGIH] Danger of sensitization of skin and airways; [MAK]
