[Spanish disinfectants for the 21st century].
There are two chemical disinfectants patents from Spain that permit to obtain advantageous products on other disinfectants: Nduopropenide (two iodures of quaternary ammonium) and "Peroxidine" (hydrogen peroxide that active to lactic acid and a surfactant mixture). The first product is used as an antiseptic or disinfectant, but the second, only act as disinfectant. DISINFECTION: It is studied (by germ-carrier methods), the microbicide effect on different microorganisms (Gram positive cocci, Gram negative bacilli, fungus, Mycobacteria and B subtilis spores), comparing these two products with different disinfectants as 2% glutaraldehyde, 1/8 phenate-glutaraldehyde, peracetic acid compounds, 11% oxygen peroxide and 2% sodium hypoclorite. It is obtained that 1/4 Peroxidine in 5 minutes or 1/6 Peroxidine in 10 minutes, are the most effective disinfectant on all microorganisms used (includes the most resistant) since it produces destruction of 4 log-10 of spores and 5 log-10 of Mycobacteria. Moreover, it can destroy, completely, the inoculum of commercial spores, routinely used for sterilization process evaluation, in 20 minutes, when 2% glutaraldehyd needs 3-10 hours. ANTISEPSIE: It is studied the "hygienization" and surgical handwashing with Nduopropenide solution, in comparison with classical washing methods (neutral soap in routinely handwashing and 5% chlorhexidine or 10% iodine-povidone in surgical washing): 1) Nduopropenide and alcohol solution is more effective that routinely handwashing. 2) This product is more effective and persistent, after surgical washing that chlorhexidine or iodine-povidone. Moreover, it does not must be applied with brush. 3) The mixture Nduopropenide and chlorhexidine makes a synergy, then it can be used in hand or skin washing, on heath personnel or patient people, being advantageous on the other products.
