Applicant's summary and conclusion

Executive summary:

Alkenes, C6-11, hydroformylation products, distn. residues, heavy cracked fraction is a UVCB substance consisting of a number of oxygenated hydrocarbon components, covering a wide range of carbon numbers and structures, each with their own log atmospheric oxidation value. Rate constant and half-lives for relevant components were predicted using the EPISuite Aopwin QSAR. The relevant components were determined based on the best available analytical data and process knowledge (see dossier sections 1.2 Composition and 1.4 Analytical methods).
