Constituent 1
Study design
- Details on sampling:
- A 10 % suspension of the test substance was prepared. Samples were taken after about 1, 2, 6, 7, 8, 9, 12, 13, 14, 15, 16, 19, 22, 26, 27, 31, 38 days.
Results and discussion
- Details on results:
- After 1 day about 11 % of the test substance were hydrolysed. After 14 days about 25 % and after 38 days only about 11 % of the disulfochloride were left.
The half-life of quinacridonedisulfochloride, 10 % aqueous suspension, is about 7 days.
Applicant's summary and conclusion
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.
