The density and relative density of MDEA-Esterquat were investigated in a study conducted according to OECD Guideline 109 (Density of Liquids and Solids; 1995) and EU Method A.3 (Relative Density; 2008). The density and relative density (D20/4) were determined to be 1.04 g/cm³ and 1.04 (mean of two measurements; at 20°C each), respectively.

Conclusions:
The density and relative density (D20/4) of MDEA-Esterquat C16-18 and C18 unsatd. were determined to be 1.04 g/cm³ and 1.04 (at 20°C each), respectively in a study conducted according to OECD Guideline 109 (Density of Liquids and Solids; 1995) and EU Method A.3 (Relative Density; 2008).
Executive summary:

The density and relative density of MDEA-Esterquat C16-18 and C18 unsatd. were investigated in a study conducted according to OECD Guideline 109 (Density of Liquids and Solids; 1995) and EU Method A.3 (Relative Density; 2008). The density and relative density (D20/4) were determined to be 1.04 g/cm³ and 1.04 (at 20°C each), respectively.
