Applicant's summary and conclusion

Conclusions:
Toxicity to reproduction to male and female Rattus norvegicus by the oral route by 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one gave an estimated LOEL as 129.0195 mg/kg bw/day from QSAR in two generation prediction. This value suggests that this chemical is unlikely to exhibit reproductive toxicity to Rattus norvegicus
Executive summary:

Toxicity to reproduction to male and female Rattus norvegicus by the oral route by 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one gave an estimated LOEL as 129.0195 mg/kg bw/day from QSAR in two generation prediction. This value suggests that this chemical is unlikely to exhibit reproductive toxicity to Rattus norvegicus
