Gum turpentine oil, consisting of the volatile fraction resulting from the distillation of oleoresin collected by tapping softwoods from pinacea derivatives (genus: pinus). It consists of terpenes, mainly monoterpenes such as alpha-pinene and beta-pinene.

Type of information:

experimental study

Adequacy of study:

key study

Study period:

August 2010

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

comparable to guideline study with acceptable restrictions

Study performed according to international guidelines but not under GLP and with some lack of details (no report number, criteria of validity not indicated).

Reason / purpose for cross-reference:

reference to same study

Reason / purpose for cross-reference:

Qualifier:

according to guideline

Guideline:

OECD Guideline 109 (Density of Liquids and Solids)

Key result

Type:

relative density

Density:

ca. 0.867 g/cm³

Temp.:

20 °C

Remarks on result:

other: relative density at 20 °C in reference with water at 4 °C

The obtained value is the mean result of three determinations at 20 ± 0.5 °C :

Assay No.	Density (kg/m3)	Relative density
1	867.4	0.8674
2	867.3	0.8673
3	867.3	0.8673
Mean ± standard deviation	867.3 ± 0.1	0.8673 ± 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 867 ± 1 kg/m3.

Conclusions:

The relative density at 20°C/4°C of GUM TURPENTINE OIL (CAS 8006-64-2) in reference with water at 4°C is 0.867 ± 0.001.

Executive summary:

The relative density of GUM TURPENTINE OIL has been measured according to OECD Guideline 109 and 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 0.867 ± 0.001.

The result has been considered as reliable with restrictions because the test was performed in compliance with guidelines giving scientifically valid results but not under GLP.

Description of key information

The relative density of GUM TURPENTINE OIL (D20/4) is 0.867 ± 0.001.

Key value for chemical safety assessment

Relative density at 20C:

0.867

Additional information

The relative density of GUM TURPENTINE OIL 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 consistent data from 2 handbooks which are in the same order of magnitude.
