Description of key information
The sensitising potential of the test item with respect to humans was evaluated in a repeated insult patch test. The test material was applied under occlusion twice a week for 4 weeks for a series of effective contact periods of two days' duration. On the second Monday following the removal of the last series of applications, the test material was applied to the same contact site as a challenge. The contact sites were examined for visible changes which, if present, were graded and recorded. Sites were re-examined twenty-four and fortyeight hours later for delayed reactions. No visible skin changes signifying reaction to injury were observed in any of the 200 subjects at any of the readings. Hence, based on the findings of the study, the test item was not considered to be a primary irritant, fatiguing agent, or sensitizer under the tested conditions.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
