Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Materials and methods

Type of sensitisation studied:
skin
Study type:
other: study with inmates
Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
The test substance was applied under occlusion to same site on the interior of the forearm, for five, alternate-day 48-hr periods.

After a 10-14 day rest period, patches were applied to previously untreated sites, for 48 hrs, under occlusion.

Applicant's summary and conclusion

Conclusions:
Jasmatone (hexyl cyclopentanone) was found to be not sensitising in a maximisation test in human subjects.
Executive summary:

In an in vivo maximisation test, conducted in human subjects (prison inmates), Jasmatone (hexyl cyclopentanone) was found to be non sensitising. There were no reactions that were considered to represent skin sensitisation in the 27 subjects tested.

Only limited study details are available and such a test would not gain ethical approval in most countries if conducted today.
