Cleaning and disinfecting agent containing an N-substituted propylene

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

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 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.

Self-decontaminating cleansing preparations

A composition of matter, preferably a liquid cleaning preparation for hard surfaces, comprising from 1 to 30, preferably 2 to 30, parts by weight of:

Aqueous liquid cleaner containing an anionic surfactant and an

Phosphonocarboxylic acids, such as phosphonosuccinic acid and especially 2-phosphonobutane-1,2,4-tricarboxylic acid, and aminopolycarboxylic acids, advantageously tetrasodium trimethylene diamine tetracetate or trisodium nitrilotriacetate, are added to aqueous or aqueous solvent-containing disinfectant solutions based on aldehydes and quaternary ammonium compounds for corrosion inhibition and pH-adjustment to 3.5-4.0, respectively. The corrosion inhibiting effect of the two salts is synergistic.

Disinfectant solutions having improved corrosion properties

Compounds which are the reaction products of a C.sub.12-14 -alkyl N-substituted 1,3-diaminopropane and glutamic acid or its 5-methyl ester, optionally alkoxylated, and optionally their salts, are useful as antimicrobial agents.

N-substituted diaminopropane/glutamic acid reaction products

A detergent composition for hard surfaces containing a fatty acid cyanamide, a secondary (non-cyanamide) surfactant and/or a water-soluble polymer.

Hard surface detergent compositions containing fatty acid cyanamides

Stable, aqueous cleaning agents containing (a) anionic and/or nonionic surfactants, optionally chlorine-stable, (b) an abrasive component and/or (c) an active-chlorine-releasing compound and, optionally, (d) dyes and (e) fragrances, characterized in (f) a further content of amorphous calcium aluminum silicates precipitated in situ; and the process of their preparation wherein the various ingredients are mixed and the amorphous calcium aluminum silicates are formed by precipitation therein.

Stable aqueous cleaning agents and a process for their production

Aqueous-based cleansers for windows, mirrors and reflecting surfaces, free of builder salts and organic solvents consisting essentially of:
