This hydrosol is distilled fresh and has no preservatives added.  The expected shelf life is around 12 months if stored in a cool, dark area.    Please note that a COA is not offered with the product as our volumes do not make this viable.  A laboratory analysis, if required, would need to be arranged by the purchaser.
