Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Adsorption / desorption
Administrative data
- Endpoint:
- adsorption / desorption: screening
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the physicochemical properties of the substance indicate that it can be expected to have a low potential for adsorption
- Justification for type of information:
- Determination of the partition coefficient in n-octanol/ Water (Log POW) of MIRAMER S512 (Reaction mass of tris(2-hydroxyethyl)isocyanurate triacrylate (THEICTA) and tris(2-hydroxyethyl)isocyanurate diacrylate (THEICDA)) was performed according to OECD TG 117 with High Performance Liquid Chromatography with UV detection. MIRAMER S512 is a multi-constituent substance. Log Pow for the major components of MIRAMER S512 was experimentally determined to be 1.767 for THEICTA and 1.121 for THEICDA and Log Pow between 0.301 and 2.742. for the minor component.
Calculating the Log Kow from the QSAR expression Log Koc= 0.81 * Log Kow +0.1 and applying the Log Kow values for THEICTA and THEICDA results in Log Koc values of 1.55 and 1.02. These values are < 4.5 indicating a low potential for adsorption
