Executive summary:

Aluminum Sulfate, Hydrate was evaluated for its acute dermal toxicity potential in New Zealand White rabbits. The study is equivalent to the OECD Guideline 402 (Acute Dermal Toxicity) with deviations. The study wasn’t designed and performed according to Good Laboratory Practice Standards.

For 24 hours 5000 mg/kg bw test substance is applied to the skin of 2 male and 2 female rabbits. This application produced some skin irritation such as erythema and haemorrhaging after treatment. No mortality occurred. All rabbits exhibited normal appearance and behaviour on day 2. The gross necropsy showed no significant gross changes, with the exception of 1 male animal which had pale lungs..

The Single Dose Acute Dermal LD₅₀of Aluminum Sulfate, Hydrate applied to the skin for 24 hours, is greater than 5000 mg/kg bw. Therfore the test material was not classified according to OECD-GHS.
