  • Patent number: 7845351
    Abstract: A face mask for reducing the amount of microbes to which a wearer is exposed is provided. The face mask includes a body portion that has an outer layer that has been treated with a germicidal agent in an effective amount. The layer may be a nonwoven fabric like a spunbond, meltblown or coform layer and may be a laminate of such layers. The face mask having such a germicidal treatment can result in a reduction in microbial activity as compared to another face mask, identical but for the germicidal agent.

  • Patent number: 7642395
    Abstract: The present invention provides a topical composition for application to the perianal and/or labial areas of the skin which helps prevent viscoelastic fluids, such as menses and feces, from attaching to the skin and aids in the reducing the viscoelastic properties of the fluid so that the fluid can flow into absorbent articles. The composition contains at least one viscoelastant material and at least one an anti-adherent material. the composition may be applied with a wipe, including mitts and gloves, a solid stick composition, an aerosol dispenser, a pump spray, a trigger spray, a squeeze bottle, as a foam, as a cream, as an ointment, as a salve, as a gel, as a wash or as a lotion. In addition, absorbent articles, such as pads or pants, diapers and the like may also be used as a means to transfer the composition to the skin.
