Claim:
A fragrance release system comprising: (a) a substantially cylindrical wick having a surface area in contact with ambient air, said wick comprising an inner core comprising a first plant-based fibrous material and an outer sheath comprising a second plant-based fibrous material, said sheath in contact with said core, said first and second plant-based materials being mutually different; (b) at least one diffuser having a surface area in contact with ambient air and comprising a plurality of substantially uniform plates, each of said plates having an end fixed into or onto said wick, said surface area of said diffuser in contact with ambient air being greater than said surface area of said wick in contact with ambient air; (c) a container with an opening configured to position said wick partially there through; and (d) a fragrance preparation stored within said container, said preparation being transported through said wick to said diffuser by capillary action against the direction of gravity when said wick is positioned in said container in contact with said preparation; and wherein the contact angle of said first plant-based fibrous material is less than the contact angle of said second plant-based fibrous material, and wherein the difference in said contact angles is at least 10°.
