Type of method:

pycnometer method

Specific details on test material used for the study:

The commercial product containing the "substance", Quaternary ammonium compounds, di-C12-18-alkyldimethyl, nitrites, CAS Number 71487 -01 -9, EC Number 275 -532 -1, in organic solvents, methanol and isopropanol (ca. 32%) was utlised for this study. Prior to this study being undertaken, these solvents were removed by, firstly, leaving the sample under a stream of nitrogen to remove the majority of the solvent(s) and, secondly, evaporating the remaining residual solvent(s) under vacuum at 60 degress C to constant dried weight of the test item. After solvent removal the substance was identified to be a yellow viscous liquid / wax like solid.

Key result

Type:

relative density

Density:

0.874 g/cm³

Temp.:

25 °C

Conclusions:

The average density for the two results obtained for the Test Item (Quaternary ammonium compounds, di-C12-18-alkyldimethyl, nitrites, CAS Number 71487-01-9), EC Number 275-532-1) was determined to be 0.8743 g/cm3.

Executive summary:

The relative density of the test item (Quaternary ammonium compounds, di-C12-18-alkyldimethyl, nitrites, CAS Number 71487-01-9, EC Number 275-532-1) was investigated in a study conducted in accordance with Innospec SOP TM007 “Relative Density”, Revision: 1.

This study is assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al (1997).

A pycnometer cup was used for the determination of the density of the Test Item. The testing was performed in duplicate with different weights of the test item and the average density for the two results obtained was determined to be 0.8743 g/cm3.
