Description of key information

C14-20 Aliphatics (≤2% aromatic) are hydrocarbon UVCBs. Standard tests for this endpoint are intended for single substances and are not appropriate for these complex substances. 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 this substance with the PETRORISK model (see Product Library in PETRORISK spreadsheet attached to IUCLID Section 13).

 

Koc of icosane has been estimated by calculation in the Concawe Library of Petrorisk, using SPARC v4.2 program (May 2008). The calculated value is 1.84 x 1011 L/kg, using a log Kow of 11.46. This result suggests that icosane is expected to be immobile in soil.
