Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Adsorption to solid soil phase is expected (log Koc = 3.89 - 4.42, KOCWIN v2.00).
Key value for chemical safety assessment
Additional information
No study investigating the adsorption potential of Fatty acids, C8-10, octyl esters (CAS 91031-98-0) is available. In Article 13 of Regulation (EC) No 1907/2006, it is laid down that information on intrinsic properties of substances may be generated by means other than tests, provided that the conditions set out in Annex XI (of the same Regulation) are met. Furthermore according to Article 25 of the same Regulation testing on vertebrate animals shall be undertaken only as a last resort.
According to Annex XI of Regulation (EC) No 1907/2006 (Q)SAR results can be used if (1) the scientific validity of the (Q)SAR model has been established, (2) the substance falls within the applicability domain of the (Q)SAR model, (3) the results are adequate for the purpose of classification and labeling and/or risk assessment and (4) adequate and reliable documentation of the applied method is provided. For the assessment of Fatty acids, C8-10, octyl esters (Q)SAR results were used for both main components: octyl octynoate and decyl octanoate (KOCWIN Program (v2.00)) . The calculations for the substance main components are based on the molecular conductivity index (MCI). The estimated log Koc values are 3.89 for octyl octynoate and 4.42 for decyl octanoate. Considering the estimated log Koc range for the main substance components an adsorption potential cannot be excluded. The criteria listed in Annex XI of Regulation (EC) No 1907/2006 are considered to be adequately fulfilled and therefore the endpoint(s) sufficiently covered and suitable for risk assessment. Hence, further experimental studies assessing the adsorption potential of Fatty acids, C8-10, octyl esters are not provided.
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.
