Applicant's summary and conclusion

Conclusions:
The validity criterion “difference between duplicate determinations” was met. The test item Palmitoyl grapevine shoot extract showed a melting range, no melting point. As the test item is UVCB product, this is considered as normal. No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.

The determination was performed in duplicate. In both determinations, a melting range was detected.
The melting range was determined as 33.9 °C – 36.0 °C (307.1 to 309.2 K). These values are the means of two independent determinations.
Executive summary:

The determination was performed in duplicate. In both determinations, a melting range was detected.

The melting range was determined as 33.9 °C – 36.0 °C (307.1 to 309.2 K). These values are the means of two independent determinations.
