  • Aqueous proteolytic enzyme-containing formulation for the cleaning of hard surfaces
    Patent number: 9725681
    Abstract: 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.

  • METHOD FOR DETERMINING THE CLEANING PERFORMANCE OF FORMULATIONS
    Publication number: 20160195512
    Abstract: A method for determining the cleaning performance of a formulation, wherein 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 analyzed in terms of quantity, the quantitative analysis of the remaining test contaminant including the removal of the remaining test contaminant from the test body.
