| 摘要 |
Particulate agents of this invention typically consist of a hydrophobic, microwave transparent liquid contained in a microwave responsive substrate. Liquid and substrate are selected to be substantially free of attendant moisture. The liquid is readily absorbed into its substrate and retained therein by capillary forces. Aggregates of such particulate agents preheated by microwave energy contain stored dry heat which is transferrable to load objects. The particulate agents may be formulated to provide a desirable fragrance along with the delivery of heat.
