Hydrosol means an aqueous solution, which comes from the Latin word for water hydro, and sol, which is a solution.

Pure dew from the plant itself the effect of mining, based on aromatic therapy or the purpose of skin care, after the condensate byproduct in the process of steam or water distillation plants in the process of distillation, can produce oil-water separation, oil floating on the surface of the aqueous solution, and the aqueous solution is pure dew peony pure dew main ingredients: alcohol alkanes esters, ketones and aromatic hydrocarbons and their derivatives, also contains a small amount of aldehyde pyran alkene and phenol, etc.; Their hair ingredients mainly benzene ethanol and linalool oxide of aldehydes and ketones is its significant antioxidant activity in pure dew in addition to contain traces of oil, also contains a lot of water-soluble substances in plant peony petals characteristics were also more likely to let the skin absorb, without adding any chemical composition such as essence, gentle no stimulation.

Truly pure dew not oil refers to pure dew for production distillation process, by changing the extraction of essential oil in the distillation process of distillation, pressure and temperature in the pressure and temperature increase of oil and water as far as possible under the function of alignment, the vaporization of aromatic components and inhibition of oil-water separation after steam entering the condenser, so enter the oil-water separator oil-water mixture of isolated oil will be very few, this kind of process condensate collected (pure dew) is the best pure dew, general collection ratio of 1:1, that is a kilo of fresh flowers to collect one kilogram of pure dew, and there is no oil slick on pure dew, properties similar to distilled water clear, fragrance is thick depressive.

The pure dew produced by China national industry is the real pure dew without oil. The essence of peony petals is in the pure dew, which is the real best pure dew.
