Remarks:
density
Type of information:
experimental study
Adequacy of study:
supporting study
Study period:
February, 2009
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Although not GLP and insufficient procedural reporting, there is no reason to doubt the results obtained from these straight forward and routinely used test. Furthermore, results are completely in line with general available information.
Qualifier:
according to guideline
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Deviations:
no
GLP compliance:
no
Type of method:
oscillating densitimeter

Type:
density
Density:
ca. 0.987 g/cm³
Temp.:
20 °C
Conclusions:
Under the study conditions, the density of the 50.2% aqueous solution of test substance was found to be 0.987 g/cm3 at 20°C (oscillating densitimeter).
Executive summary:

A study was conducted to determine the density of the 50.2% aqueous solution of the test substance, C12-16 ADBAC (50.2% active in water) according to OECD Guideline 109 (oscillating densitimeter). Under the study conditions, the density of the 50.2% aqueous solution of test substance was found to be 0.987 g/cm3 at 20°C (Mulder, 1996).

Density:
0.929 g/cm³
Temp.:
20 °C
Conclusions:
Under the study conditions, the density of the test substance was 0.929 g/cm3 at 20°C (pycnometer method).
Executive summary:

A study was conducted to determine the density of the test substance, C12-16 ADBAC (purity: 94.4%) according to OECD Guideline 109, in compliance with GLP. The pycnometer method was used in this experiement. Under the study conditions, the density of the test substance was 0.929 g/cm3 at 20 °C (Schulze, 2007).

Description of key information

The density was determined using the oscillating densitometer and pycnometer method according to OECD Guideline 109 (Schulze, 2007 and Mulder, 1996)

Key value for chemical safety assessment

Relative density at 20C:
0.929

Additional information

Pure substance: Relative density (RD) = 0.929 (Schulze, 2012); 50% aqueous solution: RD = 0.99 (Mulder, 1996)
