Description of key information

The Koc of methylparaben is estimated as 280, using a log Kow of 1.96 and a regression-derived equation.

Key value for chemical safety assessment

Additional information

The partion coefficient of methylparaben was determined to be log Pow = 1.98 (see phys.-chem. section for further details). The substance therefore can be expected to have a low potential for adsorption. According to REGULATION (EC) No 1907/2006 Annex VIII, 9.3.1. (Identification of degradation products) the study does not need to be conducted if based on the physicochemical properties the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient).

However, available information from a literature source is provided.
