Additional information
In a GLP compliant study performed to the standardised guidelines OECD 121 and EU Method C.19, the adsorption coefficient of the test material was determined using the HPLC screening method. Under the conditions of the study, the adsorption coefficient (Koc) of the test material was determined to be > 4.27 x 10^5 (Log Koc > 5.63). This value indicates that the test material is immobile.
Since the study was conducted with the read across substance, hydrocarbon waxes (petroleum), oxidised, it has been assigned a reliability score of 2 in line with the criteria of Klimisch (1997). Read across from this substance is justified on the basis of its similar physical and chemical properties to those of the registered substance. Furthermore, it has a very similar chemical structure; the registered substance is an esterified form of the read across substance.
[LogKoc: 5.63]
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.
