1 - 2.5 moles ethoxylated
In a preliminary test, the following aliquots were added to 10 g of
water and stirred slowly for 10 minutes:
Weighed sample, g
While being added to the water, solutions with increasing viscosity were
being formed, resulting in a gel after the addition of 6.85 g of the
With 6.85 g of test item being mixed into 10 g of water, a gel with a
total weight of 16.85 g has been formed. This is equivalent to 41% (w/w)
of test item in solution/gel.
As the water density will significantly increase with addition of the
test item, it can be concluded that water solubility is about 410 g/L,
resulting in a gel. Due to the fact that the formation of the gel is a
continuous process and no discrete point can be identified at which
dissolution in water switches to gelling, the water solubility can be
approximated to > 400 g/L.
> 400 g/L at 20 °C, pH = 10.04
The water solubility of the substance was determined according to EU
Method A.6 and OECD 105 (flask method). Gel formation was observed at
concentrations > 400 g/L.
