Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The acute dermal LD50 of 1,3-BDDMA is reported to be >3000 mg/kg bw in rabbit.

Based on the low systemic toxicity after acute oral administration and the calculated low dermal absorption potential (Heylings 2013, see chapter Toxicokinetics), no classification according UN-GHS is warranted.
Executive summary:

The acute dermal LD50 of 1,3-BDDMA is reported to be >3000 mg/kg bw in rabbit.

Based on the low systemic toxicity after acute oral administration and the calculated low dermal absorption potential (Heylings 2013, see chapter Toxicokinetics), no classification according UN-GHS is warranted.
