Additional information
In accordance with Article 25(3) of the REACH Regulation the robust study summaries submitted 12 years previously, are used for the purpose of the registration.
For the test substance a partition coefficient of above 4.66 at 20 °C was determined in a key study according to EU method A.8 (Huntingdon, ECHA RSS, 2017). In a supporting study a log Pow of 3.38 at 20 °C was shown (EU method A.8) (Safepharm, ECHA RSS, 2017).
