Abstract: The invention relates generally to the cleaning and disinfection of hard surfaces. The surfaces are cleaned and disinfected with a cleaning textile and a water-based preparation containing disinfectants and additive. More particularly, the invention relates to a water-based concentrate, to a water-based preparation made up therefrom and to a process for reducing the loss of active substance from disinfectant solutions using the concentrate.

Abstract: The invention relates to a powdered disinfectant containing a peroxide, an acylating agent and nonionic surfactants and to the use of this disinfectant for disinfecting surfaces and instruments, particularly in the medical field.

Abstract: The invention relates to the use of agents, which contain at least one disinfection system based on selected organic peracids and combinations of peracids, in automatically functioning systems, in which fragile medical appliances, in particular, endoscopes, are cleaned and disinfected. According to the invention, the appliances are brought into contact with an aqueous disinfection agent solution after they have been treated and/or at the same time they are being treated with an aqueous cleaning solution. The invention also relates to cleaning and disinfection agents and methods which are all suited for carrying out this purpose.

Abstract: A thickened, ready-for-use disinfectant for medical or dental suction apparatus, said disinfectant including a special active substance of amine compounds with a viscosity between 100 and 2000 mPa.s, preferably between 350 and 1000 mPa.s.

Abstract: A process is provided for disinfecting articles at temperatures below 5° C. with an aqueous alcoholic salt solution. The process provides a fast reduction of microorganisms at low temperatures with a wide degree of efficacy.

Abstract: A process useful for disinfecting medical instruments is presented involving reacting a hydrogen peroxide donor with an N-acyl compound in an aqueous medium having a pH of 9 to 11 to form an acylated hydrogen peroxide preparation, reducing the pH of the acylated hydrogen peroxide preparation to pH 7 to 9; and contacting the acylated hydrogen peroxide preparation with a medical instrument. The process provides good antimicrobial activity with little corrosion. The process is effective against mycobacteria.

Abstract: The invention relates to agents which combat the hepatitus A virus, containing only minimal amounts of chlorine-containing and/or chlorine cleaving active ingredients, or none of said substances. The inventions also relates to the use of these agents and to a method for their production.

Abstract: In order to disinfect objects at low temperatures, which can lie well below 0 ° C., said objects are treated with a hydroalcoholic solution containing an active microbicidal chlorhexidine compound. The Method enables quick reduction of germs even at low temperatures and displays a wide-ranging degree of efficacy.

Abstract: A disinfecting process is disclosed by means of aqueous peroxide compositions prepared by first reacting hydrogen peroxide or a hydrogen peroxide supplier with an N-acyl compound in an alkaline medium, then in a second step by adjusting the pH value of this alkaline solution in a range from 7 to 9.
