Additional information

The density of 2,4,7,9-Tetramethyl-5-decyne-4,7-diol, ethoxylated (1.3) is reported to be 0.94 g/cm³ at 25°C.

The density of the source substance 2,4,7,9-Tetramethyl-5-decyne-4,7-diol, ethoxylated (3.8) is reported to be 0.98 g/cm³. The minor difference in composition obviously has no relevant influence on density.
