About
A hydrosol of yellow sweet clover flowers. Gentle and traditional, but naturally contains coumarin — a listed fragrance allergen.
Melilotus Officinalis (yellow sweet clover) Flower Water (CAS 84082-81-5) is the hydrodistillation water from sweet clover flowers. The plant is well-known as a source of coumarin (the scent of newly-mown hay), and the hydrosol retains modest coumarin content plus flavonoids and water-soluble flavor compounds. Coumarin is listed as one of the EU 26 fragrance allergens (labeling required above threshold in cosmetics) and is a mild anticoagulant (oral anticoagulant drugs warfarin/dicoumarol descend from this plant's chemistry). Topical exposure at cosmetic concentrations is not an anticoagulant concern. Allergy potential is the main caveat. Typical use 1-20% in natural-positioning water phases.
