  • Method for improved stabilization of a tampon
    Patent number: 7886413
    Abstract: A method is provided for stabilizing a tampon. The method includes providing a pledget having a moisture content and including one or more metallic cation salts, compressing the pledget to produce a tampon, and applying microwave radiation to the tampon for a time sufficient to stabilize the tampon. The time to stabilize a tampon can be reduced by at least about 20% compared to the time to stabilize a tampon lacking one or more metallic cation salts.
