Description of key information

Based on the partition coefficient values reported in the literature which ranges from 0.84 to 1.03, Catechol has a low potential for bioaccumulation.

Key value for chemical safety assessment

Additional information

As no reliable data is available on the bioaccumulation potential of catechol, the assessment has to be performed based on data on n-octanol/water partition coefficient. Among the available results, one experimental study, divided in two publications (Garst & Wilson 1984, Garst 1984), was selected as a key study and give coefficient partition values ranging from 0.88 to 0.95. Other experimental and calculated results were selected as supporting studies, giving values comprised between 0.84 and 1.03. An average of all the Klimisch 2 data was calculated to obtain the key value of 0.93 used for chemical safety assessment.

Based on all the above mentioned data, catechol has a low potential for bioaccumulation.
