The most important constituents with regard to skin sensitisation are 1,(+)-citronellal (CAS 2385-77-5), citronellol (CAS 1117-61-9) and geraniol (CAS 106-24-1), present at typical concentrations of 36.27%, 12.74% and 21.56% respectively. These are all classified as skin sensitiser (Skin Sens. 1 / H317).
Applicant's summary and conclusion
- Interpretation of results:
- other: sensitising
- Remarks:
- based on CLP criteria
- Conclusions:
- The most important constituents are classified for skin sensitisation and are present well above the classification threshold of 1% for mixtures, as given in the CLP Regulation (1272/2008/EC). Based on this information, Cymbopogon Winterianus is also considered to be classified for skin sensitisation (Skin Sens. 1 / H317).
- Executive summary:
The classification of constituents of Cymbopogon Winterianus was studied (ECHA website) and used to derive a classification for the UVCB itself using the criteria outlined in Annex I of the CLP Regulation (1272/2008/EC) for eye irritation/serious eye damage.
