Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Due to the nature of the product, there is a range of water solubilities. The range for the substance oligomerisation and alkylation reaction products of 2-phenylpropene and phenol (OAPP) (previous name: phenol, methylstyrenated) begins at < 0.5 mg TOC/L and extends to ca. 7 mg TOC/l between 20 and 24 °C, depending on the loading used (5 to 100 mg/L).
Key value for chemical safety assessment
- Water solubility:
- 4 mg/L
- at the temperature of:
- 21 °C
Additional information
A number of reliable (OECD 105) GLP compliant studies were conducted using oligomerisation and alkylation reaction products of 2-phenylpropene and phenol (OAPP). Due to the nature of the product, there is a range of water solubilities. The range begins at 0.5 mg TOC/L and extends to ca. 7 mg TOC/l between 20 and 24 °C, depending on the loading of the substance added to the water. At loadings of 100 mg/L, the water-accommodated fractions amounted to 1.5 to 4 mg C/L, i.e. 1.5 to 4 % of the loading got dissolved. As typical value for OAPP, a water solubility of 4.0 mg/L was established for further use.
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.
