Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Details on study design:
Pre-Testing: The material was pre-tested on five subjects in order to determine whether sodium lauryl sulfate treatment was required, A patch of this material was applied to normal sites on the volar forearms for 48 hours under occlusion. No subject had any irritation from this material and it was decided to use SLS pre-treatment in the test.
Maximization Test (J.L.D.; Vol 47: No.5; 393-409; 1966): This material was applied under occlusion to the same site on the volar forearms of all subjects for five alternate day 48 hour periods. The patch site was pre-treated for 24 hours with 5% aqueous sodium lauryl sulfate under occlusion. The challenge sites were read on removal of the patch and 24 hours thereafter.

Results and discussion

Results of examinations:
The score of 0 in individual subjects were recorded in the challenge assay.

Applicant's summary and conclusion

Conclusions:
There were no instances of contact-sensitization from this material on the Maximization Test in 25 human volunteers.
Executive summary:

This test was conducted to determine the contact-sensitizing potential of test substance. This study was consisted of pre-test and maximization test. The challenge sites were read on removal of the patch and 24 hours thereafter.The score of 0 from individual subjects was recorded in the challenge assay. There were no instances of contact-sensitization from this material in the Maximization Test. It is unlikely that this material would present a danger of contact-sensitization in normal, intended use.
