Type:
relative density
Density:
843.2 kg/m³
Temp.:
20 °C
Remarks on result:
other: final result (mean value of two independent determinations) - relative density at 20 °C in reference with water at 4 °C

Results of two determinations are reported in the following table:

 
     Measurement           Determination
 2
  Temperature (°C)  20.0 20.0 
   Mass of the empty pycnometer (g)  31.4813 31.4813
   Mass of the pycnometer filled with ultrapure water (g)  81.5246 81.5246 
  Mass of the pycnometer filled with the test item (g)  73.7490 73.7404
  Density of the test item (kg/m3)  843.3 843.1 
  Mean Density (kg/m3)     843.2

The two determinations are within the validity criteria of the method: (less than 1% of difference).

No additional determination was performed.

Conclusions:
The relative density at 20°C of REACTION MASS OF BETA-PHELLANDRENE AND D-LIMONENE AND L-LIMONENE is 0.843.
Executive summary:

A study was performed to determine the density of the test item REACTION MASS OF BETA-PHELLANDRENE AND D-LIMONENE AND L-LIMONENE. The method followed was designed to be compliant with the OECD Guideline for Testing of Chemicals No.109, ''Density of Liquids and Solids'' and the Method A.3 of Commission Regulation No. 440/2008, ''Relative Density''. .

In this method, the density is determined at a specific temperature using a pycnometer.

Density is calculated from the difference in weight between the full and the empty pycnometer and its volume. The pycnometer volume is determined by carrying out the experiment at the selected temperature with the quantity of ultrapure water required to fill the pycnometer.

The following results were obtained:

 
 Trial  Density (kg/m3) at 20.0 +/-0.1°C
 1 843.3
 2  843.1
 Mean  843.2

These values respect validity criteria (less than 1% of difference). Moreover, the bath used to maintain the pycnometer at 20°C did not vary by more than 0.1°C.

The density of the test item was determined to be 843.2 kg/m3 at 20.0 +/-0.1°C (mean value of two independant determinations).

The relative density of the test item was determined to be D204 = 0.843

Description of key information

The relative density of Reaction mass of beta-phellandrene and d-limonene and l-limonene was determined to be 0.843.

Key value for chemical safety assessment

Relative density at 20C:
0.843

Additional information

The relative density of dipentene multi at 20°C was determined in a study performed according to OECD Guideline 109 and EU method A3 by pycnometer method. Therefore, a reliability of 1 is assigned and the result of this key study is proposed as the end point value.
