Applicant's summary and conclusion

Conclusions:

The density of the test item Palmitoyl grapevine shoot extract was calculated as 0.9610 ±
0.0002 g/cm3 at 20.0 ± 0.4 °C. This value is the mean of two independent determinations
with the maximum error of a single determination.
Standard deviation was 0.0001 g/cm3, showing very good correlation of the two determinations.
Correspondence of the values is very good. Therefore, the study is considered valid.

Executive summary:

Using the pycnometer method, a density of 0.9610 ± 0.0002 g/cm3 at 20 ± 0.4 °C was measured. This value is the mean of two independent determinations with the maximum error of a single determination. Standard deviation was 0.0001 g/cm3, showing very good correlation of the two determinations.
