Description of key information
Key information on biodegradation
Ready biodegradability: not persistent (OECD 301 D, performed with submission substance L9TM, 63% biodegradation in 60 days)
Key value for transportation and distribution
The derived log Koc (HPLC method) was > 5.67 (OECD 121, performed with analogue substance: 1,2,4-benzenetricarboxylic acid, mixed decyl and octyl triesters, C8C10TM, CAS no. 90218-76-1).
Key information on bioaccumulation
Bioaccumulation is expected to be low (log Kow >10, performed with the submission substance, see section 4.7)
Additional information
Environmental fate and pathways
With regard to biodegradation, one reliable study is available on ready biodegradation of the submission substance according to OECD 301 D (AkzoNobel, 2016, RL1). The study was performed in compliance with GLP using river water as the inoculum. As the submission substance did not meet the criteria for ready biodegradability, the test period was extended and an enhanced testing performed. In the enhanced biodegradation testing, the submission substance was degraded up to 63% at day 60 (see section 5.2.1). Accordingly, the submission substance will not persist in the environment.
The behaviour of submission substance concerning transportation and distribution in the environment was deduced from an adsorption / desorption study according to OECD 121 (LAUS, 2009, RL2, analogue substance: 1,2,4-benzenetricarboxylic acid, mixed decyl and octyl triesters, C8C10TM, CAS no. 90218-76-1). The result of the test led to an indicative log Koc (i.e., log Koc > 5.67), because the test substance had a log Koc above the reference substances. The log Koc of the test substance was determined as > 5.67 (analogue substance: C8C10TM). In conclusion, the submission substance is considered of having a high potential for adsorption to soil or sediment.
With regard to bioaccumulation, no experimental study is available. The experimentally determined log Kow of the submission substance of 10.8 was taken as indication that high potential for bioaccumulation can be ruled out: a log Kow >10 is taken as an evidence of limited bioaccumulation (in reference to Guidance on Information Requirements and CSA, R.11). Therefore, bioaccumulation is expected to be low.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
