Results and discussion

Effect levels
Sex:
not specified
Dose descriptor:
LD50
Effect level:
> 5 000 mg/kg bw
Based on:
test mat.
Remarks on result:
other: No deaths in a group of ten rats dosed at 5 g/kg
Mortality:
No deaths occurred in a group of ten rabbits administered a dose of 5g ethylhexyl palmitate/kg bw.
Clinical signs:
other: No clinical signs were recorded for any of the treated rabbits.
Gross pathology:
Necropsy revealed several macropscopic changes including :

brown anogenital exudate - 2 rabbits
Intestines, red areas - 3 rabbits; yellow areas - 1 rabbit; bloated - 1 rabbit
Liver, dark - 6 rabbits, mottled appearance - 1 rabbit; white nodules - 1 rabbit.
Dark areas on lungs - 2 rabbits
Other findings:
Nine of the ten rabbits developed slight or moderate erythema and 9/10 also had slight oedema formation.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
No deaths occurred in a group of ten rabbits dosed topically at 5g/kg with ethylhexyl palmitate. On basis of read across toa similar material, no acute dermal toxicity is anticipated for fatty acids, C12-2- and C12-20 unsaturated, 2-ethylhexyl esters and no classification for acute dermal hazard is required according to the CLP Regulation.
Executive summary:

No deaths occurred in a group of ten rabbits dosed topically at 5g/kg with ethylhexyl palmitate. On basis of read across toa similar material, no acute dermal toxicity is anticipated for fatty acids, C12-2- and C12-20 unsaturated, 2-ethylhexyl esters and no classification for acute dermal hazard is required according to the CLP Regulation.
