Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
In the acute oral toxicity study, a single dose of 5000 mg/kg bw Mandarin oil was given orally to 10 male Wistar rats. Animals were observed 3-4 hours post dosing and once daily thereafter for 14 days for mortality, toxicity and pharmacological effects. No deaths occurred, resulting in a LD50 > 5000 mg/kg bw.
In the acute dermal toxicity study, a single 24-hour application of 5000 mg/kg bw Mandarin oil was applied to the clipped abdominal skin of 7 rabbits weighing 2.0-3.0 kg. The animals were wrapped with a gauze patch and plastic, secured with tape. Following exposure, the binders were removed and daily observations made for mortality, toxicity and pharmacological effects for a period of 14 days. No animals died during the course of the study, resulting is a LD50 > 5000 mg/kg bw.
Justification for classification or non-classification
Based on the key information for both oral and dermal acute toxicity, the substance Mandarin oil does not need to be classified as acute toxic according to the EU classification criteria outlined in 1272/2008/EC and 67/548/EEC.
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.
