Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables

Tests were carried out at temperatures 20 ± 0.2 oC. Clean and dry pycnometer together with stopper and cap was weighed in laboratory scale to the nearest 0.0001 g. Next, the pycnometer was filled with Standard Water of purity 3, thermostated to test temperature (20 oC). After measuring the temperature using a thermometer, the pycnometer was dried, cooled and weighted. To determine the weight of MCPA-2EH, the pycnometer was emptied of water, dried, filled with MCPA-2EH, thermostated and was weighed after drying and cooling. According to the applied norm if the difference of results is less than 0.03 g/ml then two trials are enough.

Applicant's summary and conclusion

Conclusions:
To trials at 20 oC were done, giving results:
1.0671 g/ml
1.0672 g/ml
Executive summary:
Density of MCPA-2EH at 20 oC, as the mean of two trials, rounded to tree decimal places is 1.067 g/ml.
