Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Study type:
study with volunteers
Principles of method if other than guideline:
An approprite quantity of each concentration (0.33 and 0.66 g/mL) of the test material was applied to a Johnson & Johnson 1.8 cm x 1.8 cm band aid clinical occlusive patch. A patch containing deionized distilled water was used as a control. The patches were applied to the designated test sites on the back of each subject (55 persons; age: 18 - 60 years). After the fourty-eight hour occlusive period, the patches were removed. The test sites were graded shortly after removal of the patches once the skin had equilibrated. Twenty-four hours after the patches were removed, each site was graded again. Because some reactions may appear even later, resuls were read again 48 hours after removal of the patch.
