Notes:
↵a In the sealed vessel extracts, see Figures 18, 19. These extracts also contained extractables whose identities could not be established, specifically peaks 17, 19, 41, 56, 66, 68.
↵b In the solvent extracts, Soxhlet and Reflux, see Figures 22 and 23.
↵c Although the compounds associated with some peaks could not be identified, it was established that they were erucamide-related. Such peaks included 24, 26, 27, 28, and 36.
↵d Although the compounds associated with some peaks could not be identified, it was established that such peaks were related to Chimassorb 944. Such peaks included 32, 37 and 47.
↵e These identifications are classified as confirmed.
↵f These identifications are classified as confident.
↵g These identifications are classified as tentative.
↵h The oxide is the earlier eluting peak in the IPA/Water chromatogram shown in Figure 19.
