Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

     1st Calculation  2nd Calculation  
 Pour Density of test Item (g/cm³)  = m / V  0.6063  0.6252  0.6158
 Tap density of test Item (g/cm³)  = m / V1  0.6899  0.6669  0.6784
Conclusions:
The mean pour density and tapped density of test chemical was determined to be 0.6158 g/cm³ and 0.6784 g/cm³ at 20°C and 969.8 hPa.
Executive summary:

The density of test chemical was determined following OECD guideline 109 and according to the method recommended in the International Pharmacopoeia, fourth Edition, 2014. The mean pour density and tapped density of the test chemical was determined to be 0.6158 g/cm³ and 0.6784 g/cm³ at 20°C and 968.8 hPa.

Additional information

The density of test chemical was determined following OECD guideline 109 and according to the method recommended in the International Pharmacopoeia, fourth Edition, 2014. The mean pour density and tapped density of the test chemical was determined to be 0.6158 g/cm³ and 0.6784 g/cm³ at 20°C and 968.8 hPa.

From other experimental study report, the bulk density of test chemical by the mass by volume method was determined to be 0.625 g/cm3 at room temperature of 30 deg C

The bulk density of phenylacetic acid by the mass by volume method is found to be 0.625 g/cm3 at 30 °C. This density value at 20°C is equivalent to 0.416 g/cm3 at 20 deg C. The supporting study show values different from the key study which could be due to the difference in the estimation conditions. However for the purpose of chemical safety assessment, the key study values 0.416 g/cm3 shall be used.
