Additional information

In accordance with REACH Chapter R.7A Endpoint Specific Guidance, specifically R.7.1.17.1 Information Requirements on Dissociation Constant, if the substance cannot dissociate due to a lack of relevant functional groups, the dissociation constant is irrelevant. Di-isodecyl phthalate does not contain functional groups subject to dissociation, consequently a study is not justified.
