RESULT | LOG Bio Half-Life (days) | | 0.7764- Details on results:
- The BCFBAF version 3.01 programme of the EPI Suite software (EPISuite 4.10) was used to predict either a log BCF of 0.5 (BCF of 3.16 L/kg) based on a regression estimate or a log BAF of - 0.05 (BAF of 0.893 L/kg) based on the Arnot-Gobas upper trophic model both using the smiles codes of tristirdedecyl 2-hydroxypropane-1,2,3-tricarboxylate and trisdodecyl 2-hydroxypropane-1,2,3-tricarboxylate representing Cosmacol ECI.
Based on the expected kinetic behaviour in the body substantial amounts of Cosmacol ECI will not accumulate in the body, because it will be hydrolysed, absorbed and efficiently metabolised into water soluble metabolites, which is supported by the molecular structure of Cosmcaol ECI and its physico-chemical properties.

Applicant's summary and conclusion
- Conclusions:
- It is concluded that Cosmacol ECI will not accumulate in the body.
- Executive summary:
The BCFBAF version 3.01 programme of the EPI Suite software (v 4.10) was used to predict either a log BCF of 0.5 (BCF of 3.16 L/kg) based on a regression estimate or a log BAF of - 0.05 (BAF of 0.893 L/kg) based on the Arnot-Gobas upper trophic model both using the smiles codes of tristridecyl 2 -hydroxypropane-1,2,3 -tricarboxylate and tridodecyl 2 -hydroxypropane-1,2,3 -tricarboxylate representing Cosmacol ECI . Because the Arnot-Gobas upper trophic model takes also into account metabolism of the substance by the organism it is lower. The QSAR-data are supported by the results of the pharmacokinetics. Cosmacol ECI will be hydrolysed, absorbed and efficiently metabolised into water soluble metabolites, which is supported by the molecular structure of Cosmacol ECI and its physico-chemical properties.
It is concluded that Cosmacol ECI will not accumulate in the body.
