Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Additional information
In two ready biodegradation studies, the test substance did not meet the criteria of readily biodegradabe. In an OECD 301D test, the test substance showed a biodegradability of 40% BOD of the COD after 28 days, consistent with a description of primary, inherently biodegradable. In an OECD 301F test,cumulative oxygen demand in duplicate Test Mixtures containing the test substance did not exceed that in unamended Inoculum Blanks; thus indicating that no biodegradation of IPHA had occurred over the duration of this test. However, since cumulative oxygen consumption in the Test Mixtures was less than that in Inoculum Blanks, the results suggest that the test substance was at least partially inhibitory to the sludge inoculum under the conditions of the test.
In an OECD 306 Biodegradation in Seawater test, the test substance reached 19% degradation after 28 days based on oxygen consumption.
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.
