Endpoint summary
Administrative data
Description of key information
Additional information
Substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, the endpoints are characterized using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (version 7.04). Computer modelling is an accepted method for estimating the Adsorption/ desoprtion and environmental distribution of chemicals.
Adsorption/ desoprtion:
The compositions of both registrants were available, and both were run. For the composition 1, the model predicted a log Koc to be between 2.55 and 10.72, whereas for the composition 2, between 2.16 and 10.72 (see Product Library in PETRORISK report attached to IUCLID Section 13).
EPISUITE v4.11 KOCWIN (2017) estimates of Koc are available. For the composition 1, the model estimated log Koc of representative constituents to range from 2.73 to 11.4 and 2.31 to 7.33 Kow and MCI estimates, respectively, whereas for the composition 2 from 2.37 to 11.4 and 2.37 to 7.34 for Kow and MCI estimates, respectively.
Distribution modelling:
The compositions of both registrants were available, and both were run. For the composition 1, the model predicted the distribution of the substance to be as follows: 83.5% to air, 1.58% to water, 5.08% to soil, and 9.87% to sediment. For the composition 2, the model predicted the distribution of the substance to be as follows: 93.8% to air, 0.92% to water, 1.40% to soil, and 3.87% to sediment (see Distribution modelling results in PETRORISK report attached to IUCLID Section 13)
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.
