- Conclusions:
- The melting point of Esterification products of triglycerides C18 unsaturated with triethanolamine, dimethyl sulfate quaternized was determined to be 7±1°C.
- Executive summary:
The melting point of Esterification products of triglycerides C18 unsaturated with triethanolamine, dimethyl sulfate quaternized was determined according to EU method A.1/OECD TG 102 using the crystallizing point method. The test item did not demonstrate a phase change typical of the crystallizing point method but was observed to become significantly viscous over a short period of time and this was considered as the freezing point.
The melting point of the test item was determined to be 7±1°C.
Reference
The graphs of the temperature readings showed no sign of a freezing
point event (phase change). However, the observations recorded during
the test described how the test item became significantly more viscous
over a short time period. As the test item cooled it appeared to become
more viscous, but this was a much slower change than the significant
increase in viscosity that had occurred at 7 ± 1 °C. The procedure of
moving the loop during this test can break up a solidifying substance
giving the feeling of it being more mobile than it would have been
otherwise.
Before the crystallizing point method was used, the preliminary test of
the pour point method had been performed as it had been considered the
more appropriate method. This method utilises the gradual increase in
viscosity of a substance as it cools. However, the test recorded a
sudden stationary point at 7.0 °C when the test item had been relatively
mobile at 10.0 °C.
This observation at 7.0 °C ties in with the observations from the
crystallizing point method.
The definitive test by the pour point was not performed.
