Hydrosols are water-based byproducts of the steam distillation of essential Oils. Hydrosols contain minute amounts of certain essential oil components, mainly monoterpene alcohols. This component is the gentlest of all the components found in essential oils and cats are able to excrete them, therefore there is no build up of toxins in their bodies.

Hydrosols also contain the water-soluble portions of the plant - something which essential oils, being lipophilic, do not contain, this gives hydrosols a unique range of action. They are extraordinary gentle substances. Their very subtle fragrances make them tolerable and well accepted by cats and their highly diluted nature makes using and dosing hydrosols safe and simple.
