Endpoint conclusion

- Additional information:
In a GLP-guideline study according to OECD 406 the sensitation potential to guinea pig skin of 1-chlorobutane was examined (Buehler Test). 20 female Dunkin Hartley guinea pigs were induced with 50% n-butyl chloride in maize oil MEH 56 (w/w) by epidermal application on days 0, 7 and 14 for 6 hours. 10 guinea pigs served as control. 24 hours after the third induction exposure 6 animals exhibited slight to precisely defined skin irritations and another animal developed moderate edema and erythema. Following a rest period of 14 days the animals were exposed to the challenge dose (50% 1-chlorobutane in maize oil (w/w)). 24, 48 and 72 hours after challenge none of the animals showed changes at the exposed skin areas. Systemic toxic effects could not be detected. The general condition and body weight development of the test animals were not affected.
Migrated from Short description of key information:
-guinea pig (Buehler test): not skin sensitising (93-0264-DGT)
Justification for selection of skin sensitisation endpoint:
One study available.
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
Skin sensitisation:
The data is conclusive but not sufficient for classification according to DSD (67/548/EEC) and CLP (1272/2008/EC).
Respiratory sensitisation:
CLP: Classification is not possible due to data lacking.
