It contains trace water-soluble fragrant compounds (mainly linalool and its derivatives) but at concentrations far below the essential oil.

Lavender hydrosol (flower water) is the aqueous distillate co-produced with lavender essential oil, containing water-soluble aromatics and trace amounts of linalool and linalyl acetateSignificantly gentler than lavender essential oil — at typical hydrosol concentrations, the fragrant compounds are too dilute to cause sensitization in most individuals, while still delivering mild soothing and antimicrobial benefitCalming skin-conditioning character with very light fragrance; used as a functional water replacement in sensitive-skin and soothing formulas
Contains trace linalool — EU fragrance allergen monitoring applies; most hydrosols are well below the 0.01% threshold but individuals with confirmed linalool sensitivity should be awareDistinct from Lavandula Angustifolia Oil: the hydrosol is far safer for sensitive skin than the undiluted essential oil
