2132092 9416669 PCTABS00033 A method of impregnating tissues with an aromatic product comprises packing the tissues in a substantially sealed container together with a quantity of a volatile liquid form of the aromatic product, the volatile liquid being contained on an absorbent base which is separated from the tissues by means of a film which prevents the flow of liquid from the base to the tissues but permits the evaporation of the volatile liquid to liberate the aromatic products for absorption by the tissues. Preferably, the base is located in an envelope formed of the film whereby the film and base together form a sachet. In the case where the container is a cylinder and the tissues take the form of an open-centred roll the sachet is preferably located within the open centre of the roll.
