Description of key information
Additional information
The substance is considered readily biodegradable since 93% degraded in 28 days by meeting the criteria of the 10 day window. The toxicity control showed that the test item SymMollient S can be identified as non toxic in a ready biodegradability test. The calculated logPow is approx. 11.7 (mean value of both components).
According ECHA guidance on information requirements and chemical safety assessment - chapter R.11: PBT assessment, May 2008), “at logPow values between 4 and 5, log BCF increases linearly with logPow. This linear relationship is the basis for the B screening criterion of logPow > 4.5. However, at very high logPow (>6), a decreasing relationship between the two parameters is observed. Apart from experimental errors in the determination of BCF values for these very hydrophobic chemicals, reduced uptake due to the increasing molecular size may play a role as well. Moreover, the experimental determination of logPow for very hydrophobic chemicals is normally also very uncertain due to experimental difficulties (...) The aquatic BCF of a substance is probably lower than 2000 L/kg if the calculated logPow is higher than 10.”Thus, it can be assumed that the BCF of SymMollient S is lower than 2000 L/kg. In addition, the theoretical BMF (biomagnification factor) is 1 for organic substances with a logPow >9. For further information please refer to the CSR - PBT, vPvB assessment.
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.
