- Interpretation of results:
- irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: expert judgment

- Executive summary:
In an acute dermal toxicity study, 10 rabbits were administered a single dermal dose of Laurel leaf oil at 5000 mg/kg bw. Animals were then observed for mortality and clinical signs of toxicity for 14 days.
Dermal reactions noted were Slight redness (1/10), moderate redness (9/10), slight edema (0/10) and moderate oedema (8/10) at the site of application.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
