Abstract: It has been found according to the invention that enzymes may be effectively stabilized in high-viscosity cleaning agents even in the absence of conventional enzyme stabilizers by adding polyhydric alcohols

Abstract: It has been discovered according to the present invention that glycerol esters effectively prevent or at least decrease the discoloration of plastic dishes in the context of automatic dishwashing.

Abstract: The intention is to improve storage stability in a liquid washing or cleaning agent which contains a protease and amylase. This is achieved by using a protease which comprises an amino acid sequence which, over the entire length thereof, is at least 70% identical to the amino acid sequence stated in SEQ ID no. 1 and, in the numbering according to SEQ ID no. 1, has the amino acid substitution R99E or R99D in combination with at least two further amino acid substitutions which are selected from the group consisting of S3T, V4I and V199I.

Abstract: Rinse aids and dishwashing agents that contain anionic surfactant(s) having at least one sulfate group or sulfonate group, as well as nonionic surfactant(s), produce very good drying of the dishes cleaned in an automatic dishwashing method. The automatic dishwashing agents additionally contain polycarboxylic acid in combination with methyglycinediacetic acid or glutaminediacetic acid or ethylenediaminedisuccinic acid, or salts thereof.

Abstract: The stabilization of a hydrolytic enzyme in a liquid preparation is to be improved through a component that stabilizes the hydrolytic enzyme. This is accomplished by a method for adapting a hydrolytic enzyme to a component that stabilizes the hydrolytic enzyme, comprising the following method steps: a) providing a hydrolytic enzyme (starting enzyme) and a component that stabilizes the hydrolytic enzyme and that comprises a reversible inhibitor of the hydrolytic enzyme; b) changing the amino acid sequence of the hydrolytic enzyme in at least one position, by substitution, deletion or insertion; c) determining the relative activity of the hydrolytic enzyme from step b) and the relative activity of the starting enzyme in a liquid preparation; d) selecting the hydrolytic enzyme that has a reduced relative activity by comparison with the relative activity of the starting enzyme.

Abstract: In a dishwashing liquid, the cleaning performance, in particular on bleachable stains such as, for example, tea stains, is to be improved. This succeeds using a dishwashing liquid which comprises a hydrogen peroxide source, a bleaching catalyst and a protease that, in native electrophoresis on a polyacrylamide gel, has a migration distance that is longer than the migration distance of the protease as per SEQ ID NO. 1.

Abstract: The present invention relates to a method for obtaining novel protein variants by circular permutation, and to the novel protein variants obtained by said method.

Abstract: The present invention relates to the use of superoxide dismutases to remove Amadori and Maillard products, and to washing and cleaning agents that contain superoxide dismutases.
