Applicant's summary and conclusion

Conclusions:
The relative density of test substance was determined to be 0.95 (corresponds to D4(20)) at 23°C. The test substance (source substance) bis(hydrogenated tallow C16-C18-alkyl)hydroxylamine is a structurally very similar substance to target substance hydroxylamines, di-C16-18 (even numbered) alkyl. It can be reasonably assumed that target substance has the similar relative density.
