Natural, safe, non-staining aromatic perfection for clothing, linens, curtains, pillows and more. 100% Lavender Hydrosol. What a hydrosol is and how it’s made? When aromatic plants are distilled, two products are created in the process: The essential oil and the hydrosol. Hydrosols contain the water-soluble constituents of the plant and micro-droplets of essential oils. The properties of the hydrosol are similar to the properties of the essential oil but are much less concentrated. They have a softer, subtler aroma and a gentler action, which is why people love them too! So real hydrosols aren’t distilled water with a few drops of essential oils added and they certainly aren’t water mixed with some synthetic fragrance.
