Additional information
The available study on CAS 84989-41-3 (Melting range, Thiele/Vissers, 2003, Technical Service Work Report, Aquapel 364 analysis,rs) is based on on DSC measurement in duplo equivalent to OECD Guideline 102 (Melting point / Melting Range).
Composition:
Alkyl Ketene Dimer (AKD): 90.1% (measured by FT-IR)
High Molecular Weight fraction: 5.5% (measured by HPLC with RI-detector)
Hydrolyzed AKD (HAKD): 0.9%
Fatty Acid Anhydride (FAA): 2.2%
The melting range might be different for other compositions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
