Detailed Description:

Determine the antimicrobial properties of a proposed new product and an already approved product and a placebo (no drug). Study will be conducted using methods dictated by the FDA.

This study uses topical sampling from the abdomen and the groin on intact skin and evaluates the germs left on the skin after treatment with the proposed new product, the currently approved product and the placebo.

  • Know of allergies to vinyl, latex (rubber), alcohols, metals, inks, or tape adhesives, or to common antibacterial agents found in soaps, lotions, or ointments, particularly chlorhexidine gluconate, and/or isopropyl alcohol;
  • A medical diagnosis of a physical condition, such as a current or recent severe illness, asthma, diabetes, hepatitis, an organ transplant, any immunocompromised conditions such as AIDS (or HIV positive), mitral valve prolapse, or a requirement to take antibiotics prior to dental procedures;
  • Pregnancy, plans to become pregnant within the pre-test and test periods of the study, or nursing a child;
  • Any active skin rashes or breaks in the skin of the test sites;
