Method Details		Observed Values
		1st Observation	2nd Observation
Guideline	OECD 109
Method	IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision)
Principle of Method	Determination of the mass at a given temperature of a volume of the material contained in a density bottle (pyknometer) and determination of the volume of the latter by determining the mass of the corresponding volume of water at the same temperature. The density is obtained by dividing the mass of material by its volume.

Atmospheric pressure	(hPa)	977.4	981.6
Weight of empty dry pyknometer(X)	g	29.271	30.912
Weight of pyknometer + test item (Y)	g	83.516	85.380
Apparent mass of test item (M1)	(M1 = Y - X) g	54.245	54.468
Weight of pyknometer + water (Z)	g	78.785	80.584
Apparent mass of water (M2)	(M2 = Z - X) g	49.514	49.672
Buoyancy correction (A)	A = (*ρat × M2)	0.057	0.058

Conclusions:

The density of geranyl butyrate (CAS No. 106-29-6)was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer. The mean density of is was determined to be 1.093 g/cm³at 20.2°C and 974.5 hPa. .

Executive summary:

The density of geranyl butyrate (CAS No. 106-29-6)was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer. The mean density of is was determined to be 1.093 g/cm³at 20.2°C and 974.5 hPa.

Additional information

The density of geranyl butyrate (CAS No. 106-29-6)was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer. The mean density of is was determined to be 1.093 g/cm³at 20.2°C and 974.5 hPa.

Other supporting studies from reliable handbook suggests that the density of chemical Geranyl butyrate was determined to be in the range of 0.889 -0.904 g/cm3.

As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of density as 1.093 g/cm3 at 20.2 degree C,thus considered as key study for the chemical safety assessment.
