Additional information
Visual observations on the test material have been performed as part of a number of key toxicological and ecotoxicological experiments. The test material has most commonly been referred to as a white to off-white solid with a light yellow to pale brown colouration. The physical state is consistently reported as solid with some references describing the test material as a paste and in one case, a solidified oil. One reference to odour described the test material as having a characteristic aromatic odour.
The study investigation the physical properties of the test material was selected as the key study since it gave the most complete sample description. It is also regarded to be based on a representative purity of test material. All studies included for this endpoint were performed in line with good scientific principles and all study reports were GLP compliant and reported to a high standard. As such all studies were assigned a reliability score of 2 and considered suitable for assessment.
The available data is considered to be complete and the description, white to off-white paste at ambient conditions, was carried forward for risk assessment.
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.
