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 these substances with QSAR software (see IUCLID section 13).

 

Log Pow of icosane has been estimated by calculation in Petrorisk using SPARC v4.2. The obtained value is 11.46.

 

Log Pow of isohexadecane is >7 (company data).
