Conclusions:
The relative density of Dermosoft DGMC, reaction mass of 3-(2,3-dihydroxypropoxy)-2-hydroxypropyl decanoate and 1-(2,3-dihydroxypropoxy)-3-hydroxypropan-2-yl decanoate was determined to be 1.109 at 20 °C.
Executive summary:

The relative density of the Dermosoft DGMC, reaction mass of 3-(2,3-dihydroxypropoxy)-2-hydroxypropyl decanoate and 1-(2,3-dihydroxypropoxy)-3-hydroxypropan-2-yl decanoate was determined using a pycnometer at a temperature of 20.0 °C± 0.3 °C following test guidelines (EU method A.3, OECD 109 and EPA OPPTS 830.7300). Measurements of three independent test item samples were performed. The density of the test item was determined to be 1.109 g/cm3 corresponding to a relative density of 1.109.
