Additional information

The density of test item was determined following OECD Guideline 109 and according to theIS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer. The mean  density of test item  was determined to be 0.93g/cm³ at 20°C and 973.3 hPa.

On the basis of data modelling database, the density of test chemical was estimated to be 0.945±0.06 g/cm3 at 20°C and 101325 Pa.
