Definitions

  • the present application is directed to the use of a polyanionic substance to improve the cleaning performance of a detergent containing a protease.
  • enzymes in detergents and cleaners serve to extend the range of services of the funds concerned according to their specific activities. These include in particular hydrolytic enzymes such as proteases, amylases, lipases and cellulases. The first three hydrolyze proteins, starches and fats and thus contribute directly to soil removal. Cellulases are used in particular because of their tissue effect.
  • Another group of washing and cleaning agent enzymes are oxidative enzymes, in particular oxidases, which, if appropriate, in combination with other components, are preferably used to bleach soiling or to produce the bleaching agents in situ.
  • enzymes which are subjected to constant optimization, further enzymes are constantly being made available for use in detergents and cleaners in order to be able to optimally address particular soiling, such as pectinases, ⁇ -glucanases, mannanases or other hemicellulases for hydrolysis, in particular more specific vegetable polymers.
  • proteases and in particular serine proteases, which include the subtilases. They cause the degradation of protein-containing stains on the items to be cleaned.
  • proteases of the subtilisin type (subtilases, subtilopeptidases, EC 3.4.21.62) are particularly important, which are attributed to the serine proteases due to the catalytically active amino acids. They act as nonspecific endopeptidases, that is, they hydrolyze any acid amide linkages that are internal to peptides or proteins. Their pH optimum is usually in the clearly alkaline range.
  • Subtilases Subtilisin-like Proteases "by R. Siezen, pages 75-95 in”
  • Subtilisin enzymes edited by R. Bott and C. Betzel, New York, 1996
  • Subtilases are naturally produced by microorganisms; Of these, in particular, the subtilisins formed and secreted by Bacillus species are to be mentioned as the most important group within the subtilases.
  • subtilisin-type proteases preferably used in detergents and cleaners are the subtilisins BPN 'and Carlsberg, the protease PB92, the subtilisins 147 and 309, the alkaline protease from Bacillus lentus, in particular from Bacillus lentus DSM 5483, Subtilisin DY and the enzymes thermitase, proteinase K and the proteases TW3 and TW7, which are assigned to the subtilases, but no longer to the subtilisins in the narrower sense.
  • proteases are, for example, those under the trade names Durazym®, Relase®, Everlase®, Nafizym, Natalase®, Kannase® and Ovozyme® from Novozymes, which are available under the trade names, Purafect®, Purafect® OxP, Purafect® Prime and Properase ® from Genencor, sold under the trade name Protosol® by Advanced Biochemicals Ltd., Thane, India, under the trade name Wuxi® by Wuxi Snyder Bioproducts Ltd., China, under the trade names Proleather® and Protease P From Amano Pharmaceuticals Ltd., Nagoya, Japan, and that available under the name Proteinase K-16 from Kao Corp., Tokyo, Japan.
  • a disadvantage of these enzymes used in detergents and cleaning agents, in particular proteases, from the prior art is that they are especially at low temperatures, for example between 10 ° C and 40 ° C, in particular between 10 ° C and 30 ° C or even between 10 ° C and 25 ° C, have no satisfactory hydrolytic activity, in particular proteolytic activity, and therefore in particular in detergents and dishwashing detergents in this temperature range show no optimal cleaning performance.
  • US 6,235,697 B1 describes protease-containing detergents which additionally contain surfactants, cellulase and an acrylic acid-based homo- or copolymer.
  • EP 2 083 067 A1 describes the use of organic complexing agents and / or polymeric carboxylic acid group-containing compounds in a liquid detergent or cleaning composition to improve the washing or cleaning performance at a temperature of 40 ° C.
  • the present invention is therefore based on the object to improve the cleaning performance (washing power) of detergents or cleaning agents, in particular with regard to soiling, which are sensitive to degradation by proteases in a temperature range between 10 ° C and 30 ° C and 10 ° C. and 25 ° C.
  • Another object of the invention is the cleaning performance of hydrolytic enzymes, in particular proteases, in detergents or cleaning or the to improve by the washing or cleaning agent formed wash liquor, in particular with regard to soiling, which are sensitive to degradation by proteases in a temperature range between 10 ° C and 30 ° C and 10 ° C and 25 ° C.
  • the invention thus relates to the use of a polyanionic substance for achieving a synergistic enzyme-based cleaning performance in interaction with a protease in a washing or cleaning agent when using the washing or cleaning agent, characterized in that it is carried out in a temperature range of 10 to 30 ° C. becomes.
  • Preferred embodiments are given in claims 2-7.
  • cleaning performance is significantly improved if these agents comprise at least one protease (also referred to herein as component (a)) with one or more polyanionic substances ( Also referred to herein as component (b)) is combined.
  • cleaning performance is understood to mean the whitening performance of one or more soiling, in particular laundry soiling, which are sensitive to degradation by proteases. Examples of such stains are blood milk / ink on cotton, full egg / pigment on cotton, chocolate milk / ink on cotton, peanut oil pigment / ink on polyester / cotton, grass on cotton or cocoa on cotton, especially such as indicated below.
  • both the washing or cleaning agent which comprises the hydrolytic enzyme or the washing or cleaning liquor formed by this agent
  • the hydrolytic enzyme itself have a respective cleaning performance.
  • the cleaning performance of the hydrolytic enzyme thus contributes to the cleaning performance of the agent or the washing or cleaning liquor formed by the agent.
  • component (b) The cleaning performance of detergents and cleaning agents based on the enzymatic activity used, in particular on the proteolytic activity, is improved by the addition of component (b).
  • component (a) and (b) With regard to the interaction of these components (a) and (b), a synergistic effect results, ie a better performance compared to the individual performances of the respective component in one-component systems (ie detergents or cleaners, each containing only the hydrolytic, in particular proteolytic enzyme, or contain component (b)) and also with respect to the sum of the individual performances of components (a) and (b), ie the sum of two one-component systems each having the component (a) and (b ) alone.
  • hydrolytic enzyme (a), ie protease, with a component (b) according to the invention provides a further possibility in order to improve the performance of detergents with regard to their cleaning performance, in particular their enzyme-based cleaning performance, especially with regard to their cleaning performance, which is brought about by a protease contained.
  • the washing or cleaning liquor is understood to mean the use solution containing the washing or cleaning agent which acts on textiles or fabrics (wash liquor) or hard surfaces (cleaning liquor) and thus comes into contact with the soiling present on textiles or fabrics or hard surfaces .
  • the washing or cleaning liquor arises when the washing or cleaning process begins and the detergent or cleaning agent, for example, in a washing machine or other suitable container dissolved in water or diluted with water.
  • Hydrolytic enzymes in the sense of component (a) are proteases. These enzymes are basically of natural origin; Starting from the natural molecules, improved variants are available for use in detergents or cleaning agents, which are preferably used accordingly.
  • subtilisin type those of the subtilisin type are preferable.
  • subtilisins BPN 'and Carlsberg the protease PB92, the subtilisins 147 and 309, the alkaline protease from Bacillus lentus, subtilisin DY and the enzymes thermitase, proteinase K and the subtilases, but not the subtilisins in the narrower sense Proteases TW3 and TW7.
