Description of key information

The acute toxicity of the test item/read across was investigated in an acute toxicity study on rats. The test animals showed no clinical signs (and no mortality) up to the limit dose after oral administration. Hence, the LD50 is above 2000 mg/Kg bw.

The subsequent evaluation on the necessity of a acute test via a second route was done in accordance with Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7a: Endpoint specific guidance, Version 6.0, July 2017, p 374f.

A DermWin calculation shows a dermally absorbed dose of 2.3*10 -9 to 1.6*10 -7 mg/cm2/event. Based on the very low dermally absorbed rate and the absence of systemic effects after acute oral administration, a study on acute dermal toxicity is not required.

Furthermore, based on the lack of systemic toxicity after acute oral adminsitration, it is more than evident that an acute study on inhalation would not show any different outcome. Therefore, and due to animal welfare reasons a study on acute inhalation is not required.
