Additional information

The boiling point of the test substance was estimated using a constituents approach.

This final extract is a natural complex substance. It is a mixture of several components, and two of them represent about 98.5% of the UVCB.

The value of the boiling point of this hydroglycerinated extract of calendula is between 100°C and 290°C.
