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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Stability
Phototransformation in air
No data available (not required for REACH)
Hydrolysis
Phenol styrenated epoxidised contains an oxirane ring that is susceptible to hydrolysis under environmental conditions. The elimination half lives of the two mono-styrenated key components are 7 and 15 days, respectively, at 25°C and pH 7.
Phototransformation in water
No data available (not required for REACH)
Phototransformation in soil
No data available (not required for REACH)
Biodegradation
Biodegradation in water: screening tests
Phenol, styrenated, epoxidised is considered to be non-readily biodegradable under standard test conditions. This conclusion is supported by a study according to OECD TG 301C showing under test conditions non-biodegradability of p-cumylphenol [CAS No. 599 -64 -4], a mono-methylstyrenated substance structure-analogous with the mono-styrenated key component.
Bioaccumulation
Bioaccumulation: aquatic / sediment
No data is available on phenol styrenated, epoxidised itself. p-Cumylphenol [CAS No. 599 -64 -4] showed little bioaccumulating potential in fish, when tested in a valid standard equilibration study according to OECD 305. The BCF values ranged from 65 to 190 after 8 weeks of exposure. Furthermore, there was no significant evidence of a bioaccumulation potential of structure-related distyrenated phenol in a fish feeding study (OECD 305 -III). Hence it can be concluded that the epoxidised form of mono- and distyrenated phenol will have less bioaccumulating potential than the precursors.
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.
