Applicant's summary and conclusion

Conclusions:

In conclusion, no boiling point of fully hydrogenated high erucic acid rapeseed oil was observed up to 400 °C according to the criteria described in the guideline.

Executive summary:

The boiling point of fully hydrogenated high erucic acid rapeseed oil was determined by the capillary method (Siwoloboff) using an electronically controlled heating system according to OECD Guideline 103, EU Method A.2 and EPA OPPTS 830.7220.

In the preliminary test, a sample of the test item in a capillary glass tube was heated from room temperature up to about 400 ºC with a rate of approximately 10 ºC/min. to estimate phase transition (formation of steam bubbles) temperature. The preliminary test was performed in triplicate.

No defined boiling point could be observed in the preliminary test up to 400 °C. The colour changed from colourless to yellowish and light brown.

Because no phase transition was observed in the preliminary test, no main test was performed.

In conclusion, no boiling point of fully hydrogenated high erucic acid rapeseed oil was observed up to 400 °C according to the criteria described in the guideline.
