The density of partially unsaturated TEA-Esterquat was determined to be 1.059 g/cm³ at 20°C.

The relative density (20/4) was determined to be 1.059 using a density of water at 4°C (0.999972 g/cm³).

Conclusions:
The density of partially unsaturated TEA-Esterquat was determined to be 1.059 g/cm³ at 20°C and the relative density (20/4) was determined to be 1.059 using a density of water at 4°C (0.999972 g/cm³).
Executive summary:

The density and the relative density were determined using OECD Guideline 109 and EU-Method A.3 (air comparison pycnometer method). The density of partially unsaturated TEA-Esterquat was determined to be 1.059 g/cm³ at 20°C and the relative density (20/4) was determined to be 1.059 using a density of water at 4°C (0.999972 g/cm³).

Description of key information

density: 1.059 g/cm³ at 20°C (OECD TG 109 / EU method A.3); GLP; RL1

Key value for chemical safety assessment

Relative density at 20C:
1.059
