Conclusions:
A final value of 0.875 g/cm³ was obtained for the relative density of PPG-2 myristyl ether propionate.
Executive summary:

The relative density of PPG-2 myristyl ether propionate was determined in line with OECD Guideline 109 (Density of Liquids and Solids) without deviation. A hydrostatic balance was used to assist in the procedure so that the relative density of the liquid item could be ascertained in conjunction with the Archimedean principle. The experiment was repeated in quintuple to obtain an overall mean. PPG-2 myristyl ether propionate was concluded to have a relative density of 0.875 g/cm³ at 20 °C.

Description of key information

A relative density of 0.875 g/cm³ at 20 °C was obtained for PPG-2 myristyl ether propionate by use of a hydrostatic balance.

Key value for chemical safety assessment

Relative density at 20C:
0.875

Additional information

A Klimisch score of 1 (reliable without restriction) has been proposed for the relative density endpoint value given that it was derived from a key study performed in line with OECD Guideline 109 (Density of Liquids and Solids) without deviation.
