To Skin Antiseptic Products
|Antiseptic - a substance that prevents or arrests the growth or
action of microorganisms
either by inhibiting their activity or destroying them. Used especially
applied to living tissue. FDA(974)
The representation that a drug is an antiseptic should be considered to be a representation that it is a germicide or a bacteriostatic antiseptic drug requiring prolonged contact. FDASEC. 201. 
Two classes: the first will kill microorganisms (germicide) and the second class will inhibit their activity (bacteriostatic antiseptic) without necessarily killing them (a bandage or surgical dressing, an ointment or powder).
Washing with soap and water is the most effective way to decrease the number of microorganisms on the surface of the skin by physically removing them. Use of an antiseptic is not a substitute for washing but the second step of skin preparation used for surgical procedures and suggested for skin preparation for tattoo and piercing though T&P are not open-infection-prone wounds.
