Description of key information
The substance was not considered to be sensitizing to the skin.
Key value for chemical safety assessment
Skin sensitisation
Link to relevant study records
- Endpoint:
- skin sensitisation: in vivo (non-LLNA)
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- secondary literature
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 406 (Skin Sensitisation)
- GLP compliance:
- not specified
- Type of study:
- guinea pig maximisation test
- Justification for non-LLNA method:
- Currently no LLNA study is available for assessment. The Guinea Pig Maximization Test (GPMT) has been carried out as an animal test to predict human sensitization for over a decade and is recommended by international test guidelines such as OECD.
- Species:
- guinea pig
- Strain:
- not specified
- Sex:
- not specified
- Route:
- intradermal and epicutaneous
- Vehicle:
- unchanged (no vehicle)
- Route:
- intradermal and epicutaneous
- Vehicle:
- unchanged (no vehicle)
- Day(s)/duration:
- 24 h
- Details on study design:
- Induction was by intradermal injection of the test substance, followed after 7 days by an epicutaneous application.
After a 14 day rest period epicutaneous challenge doses were applied for 24 h and the site inspected for signs of irritation at 24 and 48 h after removal of the challenge patch. - Reading:

- 0
- Total no. in group:
- 0
- Interpretation of results:
- GHS criteria not met
Reference
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
No assessable information regarding skin sensitization in animals is available.
In poorly described publications, Ballantyne and Snellings (2007) as well as EPA (1979) found no skin-sensitizing properties (guinea pig maximization test and human patch test).
The test substance was tested to determine its ability to sensitize the skin of normal volunteer subjects using occlusive and semi-occlusive repeated insult patch tests. Three-hundred-ninetyseven (397) subjects completed the study. Under the conditions employed in this study, there was no evidence of sensitization ( TKL Research Inc., 1989)
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
Based on the available information classification for skin sensitisation is not warranted in accordance with EU Classification, Labeling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
