Key value for chemical safety assessment
Additional information
No study are available on the reaction mass of 2,4,6 -tris(1 -phenylethyl)phenol and Bis(1 -phenylethyl)phenol for this endpoint.
The two reliable studies available for the two main components (i.e. Tristyrenated phenol and Distyrenated phenol) were selected as key studies.
In the first study (NOACK, 2008) on tristyrenated phenol, all samples were checked negative for colloidal material using the Tyndall effect. For each temperature, two run were performed with different flow rates (i.e. 0.4 mL/min and 0.2 mL/min). The test item concentrations of five consecutive fractions were constant within +/- 30%. The mean values obtained from the two tests with different flow rates have an overall deviation of less than 30%. No temperature dependence of the water solubility was observed.
In the second study (NOACK, 2005) on distyrenated phenol, the aqueous solution of the poorly soluble test item has been prepared by bringing the bidistilled water into contact with slides which were previously coated with the test item. The test solution obtained was incubated at 20 +/- 0.5°C and gentle stirring at 100 rpm until equilibrium. The used Slow-stirring Method introduces only very low amounts of mechanical energy to the system. Therefore the formation of droplets or emulsions is absolutely improbable. For analysis, the peak area of two peaks of different isomers of the test item were summed and used for calculation. Two additional peaks were found in the chromatograms at approx. 2 min., which are supposed to be Mono-styrenated Phenol (impurity of the test item; identification via retention time and spectra). Other significant additional peaks were not found over the study duration, so chemical instability could not be presumed. Equilibrium was reached after approx. 60 hours and the test duration was 137.6 hours. The measured concentrations in the last four samples did not differ for more than 10%.
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).
