Floral waters
A floral water, also called hydrolate, is the aqueous distillate that remains after steam distillation of a raw material of plant origin and the separation of the essential oil. It is mostly water in which a small part of the essential oil remains trapped.
The analytical services offered by the laboratory Pyrenessences Analyses on herbal distillates:
Essential oil content
The essential oil contained in the hydrolate can be extracted to estimate its content (in mg/L).
Chromatographic profile of the essential oil contained
The composition of the extracted essential oil can be determined by gas chromatography according to ISO 11024. Two types of analysis are offered:
Classic analysis
Table with up to 80 identified compounds
Simple analysis
Table showing the major molecules (> 1%) up to 20 compounds.
Specific gravity
Ratio between the density of the sample and that of pure water at a given temperature.
pH
For “potential of hydrogen” – a number that quantifies the acidic or basic character of a solution; it varies from 0 to 14.
Multi-residue analysis of pesticides
The laboratory proposes a multi-residue research of pesticides in hydrolates.
