Endpoint summary
Administrative data
Description of key information
Adsorption / desorption
Hydrocarbons, C11-C14 n-alkanes, isoalkanes <2% aromatics is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, this endpoint is characterized using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of these substances with the PETRORISK model 7.04 (see Product Library in PETRORISK spreadsheet attached to Section 13 of the dossier). Calculated log Koc for constituents of this substance range between 3.44 and 6.35.
Volatilisation
Volatilisation is dependent on Henry's Constant (HC) which is not applicable to complex substances. However, HC values for representative structures are included in the PETRORISK spreadsheet attached to IUCLID Section 13. The HC for Hydrocarbons, C11-C14 n-alkanes, isoalkanes, <2% aromatics ranges from 0.02 to 12.42 atm-m3/mol
Distribution modelling
The distribution of Hydrocarbons, C11-14 n-alkanes, isoalkanes, <2% aromatics in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model, version 5.2/5.3. Computer modelLing is an accepted method for estimating the environmental distribution of chemicals. Distribution modelling results are included in the 'Multimedia distribution modelling results' tab in the PETRORISK spreadsheet attached to IUCLID section 13.
Based on the regional scale exposure assessment, the multimedia distribution of Hydrocarbons, C11-C14, n-alkanes, isoalkanes, <2% aromatics is 29% to air, 2.6% to water, 9.1% to soil and 60% to sediment.
Additional information
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.
