Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Applicant's summary and conclusion

The test substance has a wide melting range from approx. 56°C to 92°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 melting point range.
