Description of key information
Key value for chemical safety assessment
Skin sensitisation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (sensitising)
- Additional information:
- The key study is a local lymph node assay performed with major constituent
limonene which was read across to mandarin oil. The study was performed in
CBA/Ca strain mice according to OECD guideline 429 and in compliance with
GLP.
Mean DPM for 0, 10, 25, 50, 75 or 100% d-limonene were observed to be 2511, 3319, 8554, 9916, 22063 or 16259 dpm, respectively. Stimulation index for 10, 25, 50, 75 or 100% d-limonene were calculated to be 1.3, 3.4, 4.0, 8.8 or 6.5, respectively. The estimated concentration giving rise to a 3 fold increase in lymphocyte proliferation (EC3) was 22% v/v (5500 µg/cm2). No increase in visual levels of irritancy to the ear skin was observed during the study.
Under the test conditions, d-limonene is classified as ‘R43 May cause sensitisation by skin contact’, according to the criteria of Annex VI to the Directive 67/548/EEC and ‘Category 1’ according to the CLP Regulation (EC) N° (1272-2008).
Migrated from Short description of key information:
Read across based on d-limonene content: sensitising
Justification for classification or non-classification
Based on the skin sensitising properties of the major constituent of mandarin oil, d-limonene, mandarin oil has to be labelled as skin sensitiser in accordance with the criteria outlined in Annex VI of 67/548/EEC and Annex I of 1272/2008/EC (CLP/EU-GHS)
