Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The density of hydrogenated tallow/nortallow based IQAC was determined to be 1.0652 g/cm³ at 20°C.
Executive summary:

In a study conducted according to OECD guideline 109 the density of hydrogenated tallow/nortallow base IQAC was determined using a gas comparison pycnometer. The measurements were repeated automatically until the results of at least five subsequent runs were within the specified tolerance (deviation of displaced volume < 0,006 cm³). The density was determined to be 1.0652 cm³ at 20°C.
