摘要:
An aqueous formulation includes a) one or more proteolytic enzymes, b) one or more anionic surfactants, c) one or more non-ionic surfactants, d) one or more corrosion inhibitors, e) one or more multivalent aliphatic alcohols, f) one or more complexing agents, and g) one or more of para-hydroxybenzoic acid and esters thereof. The pH value of the formulation is in the range of from 9. to 12.5. The formulation is used in the mechanical cleaning of hard surfaces, in particular of medical instruments, and is preferably silicate free.
摘要:
The invention relates to a textile fabric impregnated with an alcoholic preparation. The effect thereof regarding the ratio between delivery and uptake is exploited to impregnate nonwovens having a high uptake capacity moderately only while nonetheless making possible a high quantitative delivery of volatile actives to the surfaces to be disinfected.
摘要:
The invention relates to a method for determining the cleaning performance of a formulation. In the method a) the formulation is provided, b) a test body is brought into contact with the formulation, the test body being contaminated with a protein-containing test contaminant, c) the contaminated test body is left in contact with the formulation in order to clean the contaminated test body, d) the cleaned test body is rinsed, e) if necessary the rinsed test body is dried, f) if necessary the test contaminant remaining on the test body is evaluated in terms of quality and g) the test contaminant remaining on the test body is analysed in terms of quantity, the quantitative analysis of the remaining test contaminant including the removal of the remaining test contaminant from the test body. By means of the method the evaluation of the cleaning performance of formulations for the machine cleaning of hard surfaces, in particular medical devices, is made easier, in particular with regard to protein-containing contaminants.
