The determination of the relative density of the test item was performed in accordance with the EC directive 92/69, EEC Publication No. L383, December 1992 and Council Regulation EC No. 440/2008, Methods for the determination of physico-chemical properties, A.3 Relative density, as well as the OECD Guideline for Testing of Chemicals, No. 109, Density of Liquids and Solids using an oscillating densitimeter. As the density of the test item was determined at 20.0 °C, the relative density is stated.

 

First, the apparatus was tested by determination of the density of air and water at 20.0 °C. The results for water are given in Table 1. These values are in the accepted range of 0.9982 ± 0.0003 g/cm³.

 

Table 2 shows the individual measurements for the density of 2-ethylhexyl 4-methoxycinnamate. From these, the mean value was calculated, corrected and given in the same table. The tabulated values represent rounded results obtained from calculation using the exact raw data. The relative density of 2-ethylhexyl 4-methoxycinnamate was determined to be  D²⁰₄ = 1.0104.

Table 1       Results of the Calibration Using Air and Water

Test No.	Temperature [°C]	Density of water [g/cm3]
		measured	mean value	theoretical value
1	20.0	0.9982
2	20.0	0.9982	0.9982	0.9982
3	20.0	0.9982

 

The density of air was measured to be 0.0012 g/cm³.

 

 

Table 2       Determination of the Density of the Test Item

Test No.	Temperature [°C]	Density of 2-ethylhexyl 4-methoxycinnamate [g/cm3]
		measured	mean value	corrected for relative density
1	20.0	1.0104	1.0104	1.0104
2	20.0	1.0104

 

 

Calculation of the relative density

 

 = 1.0104 g/cm³ / 0.99997 g/cm³ = 1.0104

Conclusions:

The relative density of 2-ethylhexyl 4-methoxycinnamate was determined to be 1.0104.

Executive summary:

First, the apparatus was tested by determination of the density of air and water at 20.0 °C. The results for water are given in Table 1. These values are in the accepted range of 0.9982 ± 0.0003 g/cm³. 

The relative density of 2-ethylhexyl 4-methoxycinnamate was determined to be D²⁰₄ = 1.0104.
