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.
