Any other information on results incl. tables

Results were not reported in detail. The LD50 was >20 ml/kg. (>16,800 mg/kg using the density of 0.84 g/cm3 reported in chapter 2.3). No further 

details available.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The LD50 of >20 ml/kg is reported in a relaible study conducted according to appropriate protocol. The study is a read across from 1-icosanol (CAS 629-96-9).
Executive summary:

In an acute dermal toxicity study, the test material (icosan-1 -ol) was applied onto rabbit skin and kept in contact to the skin for 4 hours under occlusive dressing. There is lack of detail on the materials and methods used, as well as results, however the study reports an LD50 value of > 20 ml/kg (>16,800 mg/kg using the density of 0.84 g/cm3 reported in chapter 2.3). The study meets generally accepted scientific principles, acceptable for assessment. Study considered valid although result reporting is limited. The study is a read across from icosan-1-ol (CAS 629-96-9).
