Description of key information
As Naphtol-AS Pigments are highly insoluble in water, potential for biodegradation was assumed to be low. Thus instead of testing ready biodegradability which certainly would have led to negative results, inherent biodegradability was assessed in the Modified MITI Test (II) according to OECD 302 C. This test was performed on Pigment Red 210, the pigment of the read across approach with the highest solubility in water (34 µg/L). The reliable test (without restrictions, reliability category 1) was performed compliant to GLP and fulfills validity criteria of the guideline. Biodegradation rate of the functional control aniline demonstrated the activity of the test system. No biodegradation was observed in this test (mean biodegradation rate: 0% within 28 days).
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.
