The invention is a process for cleaning and disinfection of heat and corrosion sensitive medical instruments, particularly endoscopes in which the surfaces of the medical instruments are contacted with a detergent and disinfectant solution. The solution has a pH of from 6 to 8 and contains a low foaming nonionic surfactant, a proteolytic enzyme, a complexing agent, and an aldehyde selected from the group consisting of formaldehyde and aliphatic dialdehydes containing 2 to 8 carbon atoms and, optionally, other standard detergent and disinfectant constituents. The cleaning solution is heated to 55.degree. to 65.degree. C. and kept at that temperature for 1 to 15 minutes during contact with the surfaces of a medical instrument. The surfaces are rinsed at least twice with water, the water being heated to 55.degree. to 65.degree. C. at least in the last rinse cycle and the medical instruments are dried with sterilized hot air at a temperature of 40.degree. to 60.degree. C. Water having a hardness of 3.degree. to 8.degree. Gh is used.

Liquid, aqueous disinfectant preparations containing a combination of

Disinfectant compositions

The use of compositions containing bis- or oligo-bis-guanides, alcohols, hydrogen peroxide, carboxylic acids, and water, applied externally, provides for the effective control of eggs of the threadworm Enterobius vermicularis on the skin.

Pharmaceutical compositions effective for treating skin to destroy eggs

Liquid, aqueous disinfectants based on alcohol and hydrogen peroxide which contain one or more C.sub.2 -C.sub.8 alcohols, hydrogen peroxide or a compound which forms peroxide in aqueous phase, one or more carboxylic acids, one or more microbicidally active nitrogen-containing organic compounds, one or more microbicidally active phenolic compounds, and optionally other active substances and/or auxiliaries typically present in disinfectants, and to the use of such disinfectants for disinfection of the skin and mucous membrane.

Disinfectants and their use for disinfecting the skin and mucous membrane

A method for determining the disinfecting effect of a disinfectant, in which the disinfectant is applied to filter paper, polulated with luminescent or luminous bacteria, with a number average pore size of 6 to 8.mu. and the reduction in luminescence or luminous power is compared with that of untreated areas of the filter paper. This method provides a rapid and uncomplicated, qualitative or quantitative determination of the effectiveness of a disinfectant.

A two component disinfecting and cleaning system for contact lenses comprising a first component containing a peroxo compound and an alkyl glucoside and a second component containing an H.sub.2 O.sub.2 -neutralilzing agent and a buffer salt in an amount sufficient to adjust the pH of an aqueous contact lens solution containing the first and second components to about 7.

Disinfecting and cleaning system for contact lenses

A microbially self-decontaminating dermatological cleansing concentrate containing at least one washing-active surfactant and at least one standard cleansing concentrate additive, and having a viscosity of about 500 to 5,000 mPas, improved by incorporating hydrogen peroxide, at least one fatty acid alkanolamide, and at least one water soluble alkali salt or ammonium salt; and a method for its use.
