In accordance with FDA specifications substances are used as anti-microbial agents are:
1. Alcohols & Glycerine : Most alcohol-based solutions used isoprophanol, ethanol, n-propanol or combinations of two products in concentrations of 65 to 90%. Start time has faster action, not used to remove dirt.It is normally used in hand sanitizer.
2. Chlorhexidine: chlorhexidine gluconate preparations in concentrations of 0.5 to 1.0%. It has a start-up period through action and long residual effect, Six (6) hours. Is inhibited by non ionic surfactants, inorganic and organic anions.
3. Clorhoxylenol : phenolic substance halogen substitute its effectiveness is good but its greatest strength is in its low absorption through the skin. Its concentration should be between 0.3 and 3.75%.
4. Iodine : It is recognized as an excellent antiseptic but can cause irritation of the skin. Iodine solutions are presented as an alternative but requires a concentration of 8% in soaps and 10% in disinfecting solutions.
