Description of key information

Volatilisation is dependent on Henry's Constant (HC) which is not applicable to complex substances.

Standard tests for atmospheric oxidation half-lives 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 the PETRORISK model (see library tab in PETRORISK spreadsheet attached to IUCLID section 13).

 

Henry's law constant for icosane has been estimated in the Concawe library, using SPARC v4.2 program. The obtained value is 55.6 atm-m3/mol.

Key value for chemical safety assessment
