  • the moisture control material that has been saturated with the scented material comprises a silica gel and/or a clay which has been saturated with the scented additive, preferably a scent imparting material, as earlier described. It has been surprisingly discovered that when silica gel and/or clays, which have been saturated with a scented additive, are placed within a vessel, the relative humidity within that vessel can be regulated because of the capacity of the silica gel or clay to adsorb moisture preferentially to the scented additive that has previously been absorbed by the silica gel.
  • moisture control materials preferably silica gel or clay
  • moisture control materials preferentially desorbs the scented additive, such as the scent imparting materials described herein, while preferentially replacing that scent imparting material with moisture.
