Results and discussion

Density

Type:

relative density

Density:

1.053

Temp.:

20 °C

Remarks on result:

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

Any other information on results incl. tables

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

Assay No.	Density (kg/m3)	Relative density
1	1053	1.053
2	1053	1.053
3	1053	1.053
Mean ± standard deviation	1053 ± 1.0	1.053 ± 0.001

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 1053 ± 1 kg/m3.

Applicant's summary and conclusion

Conclusions:

The relative density at 20°C/4°C of α-ETHYL-p-METHOXYBENZYL ALCOHOL is 1.053 ± 0.001.

Executive summary:

The relative density of α-ETHYL-p-METHOXYBENZYL ALCOHOL 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 1.053 ± 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, criteria of validity of the results not given).
