Literature data (CRC Handbook of Chemistry and Physics 75th Edition):

d (20, w) (density of water at 20 °C) = 0.9982 g/mL

d (4, w) (density of water at 4 °C) = 0.99997 g/mL

d (20, a) (density of air at 20 °C) = 0.0012 g/mL

Conclusions:
The relative density of Solvent Violet 59 compared to the density of water was determined to be 1.374 (mean value) measured at 20 °C.
Executive summary:

The determination of the Physico-Chemical properties was based on the OECD Guidelines for Testing of Chemicals, Section 1 – Physical-Chemical Properties No: 109 “Density of Liquids and Solids“ and to Council Regulations EC No 440/2008, Guideline Part A – Methods for the Determination of Physico-Chemical Properties, A.3. “Relative density”. The relative density was determined by displacement method. The solid sample was weighed into a pycnometer (or vial) and by displacement of a solvent, its equivalent volume is determined to calculate the density. The relative density of Solvent violet 59 was determined by comparing the ratio of density of the test substance to the density of water. The relative density of the test item compared to the density of water was determined to be 1.374 (mean value of 2 determinations) measured at 20 °C.

The bulk density was calculated by dividing the mass of the substance by the volume of the vessel.

Conclusions:
The bulk density of Solvent Violet 59 was 0.39 g/mL measured at ambient temperature.
Executive summary:

According to the German standard method "DIN EN ISO 697 'Determination of apparent Density'" the mass of the empty vessel was determined. The funnel of the filling equipment was completely filled with the substanceand the vessel was placed under the funnel and the closing plate was removed. The substance fell down in the vessel and the overlaying substance was removed by a scraper, so that the vessel was completely filled without overlying. The mass of the filled vessel was determined and the mass of the substance inside the vessel was calculated by subtraction of the mass of the empty vessel. The bulk density was calculated by dividing the mass of the substance by the volume of the vessel. The determination was repeated one time. The volume of the vessel is 499.6 mL. The bulk density of Solvent Violet 59 was 0.39 g/mL measured at ambient temperature.

Description of key information

The relative density of Solvent Violet 59 compared to the density of water was determined to be 1.374 (mean value) measured at 20 °C.

Key value for chemical safety assessment

Relative density at 20C:
1.374

Additional information

The relative density of the test item was determined by comparing the ratio of density of the test substance to the density of water.

In another study the bulk density of Solvent Violet 59 was determined to be 0.390 g/mL measured at ambient temperature.
