A daily perventive method reduces infection risk associated with artificial nails. When applied as a spray or gel soak to the nail and periungal areas, bacterial and fungal counts are significantly reduced. It is a well established medical fact that hand to hand contact is the #1 mode of transmission of infection. Artificial nails act as carriers when applied onto natural fingernails. Attached to the human hand they transmit bacteria one to another on personal contact. The porous composition of artificial nails along with additional gaps and separation created by natural nail growth; provides a template for which skin organisms are trapped and grow. Artificial nails attract water moisture on contact (bandwashing); remaining damp they act as a template which supports growth of organisms. The utility for this product is referenced by national reports of infant morbity linked to nurses wearing artificial nails, Oklahoma (1999). This pH driven nail sanitizing solution combined with a drying agent significantly reduces bacterial and fungal accummulation. As a proactive approach this antiseptic nail sanitizing solution directly challenges growth requirements of many skin microrganisms.
