EC number: 939-707-2
CAS number: -
Experimental value of relative density at 20.9°C: 1.411 +/-0.05
The determination of the density was performed by stereopycnometer
method according to EU Method A.3, OECD guideline 109 and GLP. No
deviation from the guidelines was observed during the test.
The accuracy of the apparatus was assessed using a reference standard.
The apparatus was considered acceptable for use according to the result
obtained with the reference standard.
The relative density determined for the test substance is close to the
value of an analogue substance. The analogue is "Reaction product of
naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda"
having a relative density at 20°C of 1.525. The same method was
used for the analogue substance and the test substance to determine this
parameter . The slight difference between these two values can be
explained by the process used to obtained the sample. In one case (for
the test item), an aqueous commercial solution was dried to get a sample
without water. In the other case, the analogue substance is marketed
without water on a solid form. It was not necessary to dried a sample to
