Executive summary:

Leadscope Model Applier v3.0.0-30 was used to predict the acute oral toxicity of (1,2,4,6)-2,2,7-trimethyl-3-oxatricyclo[4.1.1.02,4]octane.

The query structure was predicted as GHS category III in Leadscope using Acute Rat Oral Model v2 model.

Based on these results, the test substance is considered as Toxic if swallowed according to Regulation (EC) No. 1272/2008 and UN GHS criteria.

Additional information

leadscope Model Applier v3.0.0-30 was used to predict the acute oral toxicity of (1,2,4,6)-2,2,7-trimethyl-3-oxatricyclo[4.1.1.02,4]octane.

The query structure was predicted as GHS category III in Leadscope using Acute Rat Oral Model v2 model. Therefore the test substance is considered as Toxic if swallowed according to the Regulation (EC) No. 1272/2008.

 

 

Justification for classification or non-classification

Harmonized classification:

The substance has no harmonized classification according to the Regulation (EC) No. 1272/2008.

Self classification:

Acute toxicity (Oral):

Based on the Leadscope prediction, the test substance is classified into Category III (Toxic if swallowed, H301) according to the Regulation (EC) No. 1272/2008 and to the GHS criteria.
