Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
E96095 exhibiting a low water solubility (<1 µg/L), it has to be considered as a difficult substance to be tested particularly for: (i) achieving exposure concentration and (ii) preparing representative media.
The hydrolysis study was not conducted, the test item being highly insoluble in water.
In a standard screening biodegradation test (CO2 evolution test; OECD testing guideline 301B), the percentage of biodegradation of test material was determined at 9% based on TCO2 after 29 days of exposure. E96095 does not meet the readily biodegradable criterion.
In a sealed vessels carbon dioxyde production test (ISO 14593 and EPA OPPTS 835.3120 guidelines) , the percentage of biodegradation of test material + silicone oil was 37 % based on inorganic carbon analysis after 56 days of exposure. E96095 is considered ultimately biodegradable when enhancing measures (inert carrier) are used to improve its bioavailability and when the incubation period is extended longer than the standard 28-day ready biodegradation screening test.
E96095 is not readily biodegradable but evidence of primary biodegradation is provided.
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.
