EC number: 227-813-5
CAS number: 5989-27-5
The obtained value is the mean result of
three determinations at 20 ± 0.5 °C :
Mean ± standard deviation
844.1 ± 0.1
0.8441 ± 0.0001
Relative density = density (kg/m3) / 999.975
(kg/m3) (density of water at 4°C).
The average density at 20°C ± 0.5 °C of the
test item is 844 ± 1 kg/m3.
The relative density of D-LIMONENE has been
measured according to OECD Guideline 109 and to EU Method A.3.
Using an oscillating densimeter, the
relative density of the test item at 20°C in reference with water at 4°C
(D20/4) was determined as 0.844 ± 0.001.
The result has been considered as reliable
with restrictions because the test was performed in complinace with
edicted guidelines giving scientifically valid results but some details
are lacking in the report (no GLP, no report number, criteria of
validity of the results not given).
A study was conducted to determine the
density of (+)-limonene using Anton Paar (DMA58) densimeter.
The density of (+)-limonene was measured to
be 0.83731 g/cm3 at 298.15 K.
The relative density of d-limonene was
reported in the Merck Index 2006 as 0.8402 at 21 °C against water at 4
The reliability of this result has been
considered as 2 (reliable with restrictions) because ‘The Merck Index’
is cited as a reference book containing peer reviewed data in the REACH
Guidance Document R.7a.
The relative density of dl-limonene was
reported in the Merck Index 2006 as 0.8402 at 20.85 °C against water at
The relative density of l-limonene was
reported in The Merck Index 2006 as 0.8407 at 20.5 °C against water at 4
The relative density of D-LIMONENE at 20 °C (D20/4) is 0.844 ± 0.001.
The relative density of D-LIMONENE at 20°C
in reference with water at 4°C was determined in a study performed
according to OECD guideline 109 and EU method A3 using an oscillating
densimeter. The value was considered with a reliability of 2 (reliable
with restrictions) because the result is scientifically acceptable but
not obtained under GLP and some details were lacking in the report.
However the relative density is valid as key value and supported by
several studies measuring density or relative density of d-, l- or
dl-limonene at different temperatures.
