Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
adverse effect observed (sensitising)
Additional information:

Based on an available publication (Klecak, 1985) in which Cassia oil was found to be sensitising in human (4% HMT/RIPT) and guinea pigs (OET) Cassia oil is considered to be a potential skin sensitiser. Additionally, the constituent Cinnamic aldehyde - trans (CAS 14371-10-9), present at a typical concentration of 77%, is currently classified as H317 (Skin Sens. 1). Based on this information Cassia oil is considered to be classified as H317 (Skin Sens. 1) as well and therefore further testing is deemed not required. 

Justification for classification or non-classification

Based on the available data on skin sensitising properties the substance needs to be classified for Skin Sensitisation (Skin Sens. 1/ H317) in accordance with the criteria outlined in Annex I of the CLP Regulation (1272/2008/EC).
