Description of key information

Key calculated data is available for 2,2,3-trimethylbutane. This data is supported by available data from Isoheptane that is being read across to using the category approach explained in the category justification document attached to Section 13 of the dossier.

The partition co-efficient for 2,2,3-trimethylbutane calculated in PETRORISK is 3.59.

The partition co-efficient for isoheptane was estimated to be 3.7 (HSPA Consortium, 2010).
