Endpoint summary
Administrative data
Description of key information
For skin irritation/corrosion, no adverse effects were observed in two in-vitro studies.
Adverse effects were observed in an in-vivo acute dermal toxicity study.
For Eye irritation, an adverse effect was observed in the BCOP in-vitro test.
Key value for chemical safety assessment
Skin irritation / corrosion
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Eye irritation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Respiratory irritation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Additional information
Using the weight of evidence approach for skin irritation/corrosion it is concluded, that the substance has skin irritating properties:
1.) The available in-vitro skin irritation/corrosion studies indicate no adverse effects.
2.) For the in-vivo acute dermal toxicity study local effects are observed. These effects are erythema which are fully reversible within 7 days and scaling.
3.) The in-vitro Eye corrosion study shows adverse effects on the eye, the substance is characterised as severe irritating for the eye.
Taking together arguments 2.) and 3.), the substance may be irritant or corrosive to the skin.
The described observation from argument 2.) indicate only irritant properties.
Therefore the irritant/corrosive properties of the substance with regard to the skin can be described as "irritating".
The eye corrosion property of the substance is studied using the BCOP in-vitro test. A valid result is obtained showing corrosive properties. Further testing is not needed.
Justification for selection of skin irritation / corrosion endpoint:
From the available Endpoints non is choosen as the performed in-vitro studies indicate no effects. Justification for the Endpoint conclusion is based on local adverse effects observed in an in-vivo acute dermal toxicity study and adverse effects in an in-vitro eye irritation/corrosion study (see Discussion) .
Justification for selection of eye irritation endpoint:
only one valid in-vitro study available.
Effects on skin irritation/corrosion: irritating
Effects on eye irritation: highly irritating
Justification for classification or non-classification
