Description of key information
Diammonium persulfate was tested for skin irritation in rabbits in three studies. According to these studies, diammonium persulfate showed no skin irritation to intact skin. However, on abraded skin the test item showed severe skin irritation. Diammonium persulfate was tested for eye irritation in rabbits in two studies. Diammonium persulfate was considered to be slightly irritating to the eye in one study, while in the second study diammonium was not irritating to eyes. Diammonium persulfate was considered as eye and skin irritant based on human case studies. Based on results of a subchronic inhalation toxicity study diammonium persulfate revealed respiratory irritation properties. Additional studies were available for substances of the Persulfate Category, dipotassium persulfate and disodium persulfate.

Diammonium persulfate was tested for eye irritation properties in rabbits according to OECD guideline 405. 0.1 mL of the test item was placed into the conjunctival sac of one eye of the animals. The untreated eye served as control. One hour after application cornea irritation and diffuse areas of opacity was observed in one of the three animals. Conjunctival redness, obvious swelling with partial eversion of lids plus hypersecretion were observed in one animal, one hour after application. 72 hours after application full recovery was observed. The determined irritating index was 10.5. Under the conditions of this study diammonium persulfate was considered to be slightly irritating to eyes. No systemic-toxic effects were observed and the general state of the animals was good throughout the study period.

Additional information
All substances of the Persulfate category share the same anionic persulfate moiety and similar toxicological properties. Diammonium persulfate, dipotassium persulfate and disodium persulfate were tested in animal studies for skin irritation/corrosion and eye irritation and diammonium persulfate was examined for respiratory irritation in a subchronic inhalation toxicity study. Additionally, human data was available for dipotassium persulfate and diammonium persulfate.
Diammonium persulfate was tested for skin irritation in rabbits in three studies. According to these studies, diammonium persulfate showed no skin irritation to intact skin. However, on abraded skin the test item showed severe skin irritation.
Diammonium persulfate was tested for eye irritation in rabbits in a study according to OECD guideline 405. In this study, diammonium persulfate was shown to be slightly irritating. In a second study, diammonium persulfate was tested for eye irritation in rabbits according to guideline EPA OPP 81-4 and revealed no eye irritation effects. However, human case data revealed eye irritant properties.
Indications for respiratory tract irritation were observed in subchronic (13 weeks) whole-body inhalation toxicity study with diammonium persulfate in Sprague-Dawley rats. At respirable dust concentrations of 0, 0.5, 10.3 and 25 mg/m³ irritation of the trachea and bronchi was noted microscopically at concentrations of 25 mg/m³.
For the Persulfate Category worst-case results were considered for safety assessment:
Skin irritation: irritating
Eye irritation: irritating
Respiratory irritation: irritating
Justification for classification or non-classification
The available data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on animal test results and human case study data, substances of the Persulfate Category were classified as eye irritant, cat. 2 H319 (causes serious eye irritation), skin irritant cat. 2 H315 (causes skin irritation) and respiratory tract irritant cat. 3 STOT SE 3 H335 (causes respiratory tract irritation) according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Regulation (EU) No 2020/1182.
