Description

The invention is in the field of detergents containing specific amylases which are stabilized by betaine and their use for cleaning and / or disinfecting surfaces, in particular hard surfaces.

The use of amylases in detergents per se is known. However, the effectiveness, in particular against starch-containing stains, of a cleaning agent which contains amylases may decrease over time, that is to say by storage of this cleaning agent. Without being bound to any theory, it is believed that the amylase loses its tertiary structure in the detergent by the action of other ingredients and thus no longer shows any enzymatic effect. There is a need to produce detergents which have good or excellent cleaning performance over starch-containing stains even after prolonged storage.

The object of the present invention was therefore to provide a cleaning agent, in particular amine oxide-based, which even after prolonged storage, in particular more than 3 months, shows an almost similar cleaning performance against starch-containing stains, such as the detergent immediately after its preparation.

It has now surprisingly been found that the problem underlying the present invention can be solved by the use of a certain amount of betaine, in particular cocoamidopropylbetaine, in combination with a specific amount of the specific amylases with SEQ ID NO: 1 or SEQ ID NO: 2 or a combination of them.

According to the invention, the cleaning agent also contains one or more fatty alcohol ether sulfates. Fatty alcohol ether sulfates allow a stable foam volume in the presence of dirt, especially fatty soils on the surfaces to be cleaned or in water. Fatty alcohol ether sulfates are products of sulfation reactions on alkoxylated alcohols. The person skilled in the art generally understands by alkoxylated alcohols the reaction products of alkylene oxide, preferably ethylene oxide, with alcohols, in the context of the present invention preferably with longer-chain alcohols, ie with aliphatic straight-chain or mono- or multi-branched, acyclic or cyclic, saturated or mono- or polysubstituted unsaturated, preferably straight-chain, acyclic, saturated alcohols having 6 to 22, preferably 8 to 18, in particular 10 to 16 and particularly preferably 12 to 14 carbon atoms. In general, from n moles of ethylene oxide and one mole of alcohol, depending on the reaction conditions, a complex mixture of addition products of different degrees of ethoxylation (n = 1 to 30, preferably 1 to 20, especially 1 to 10, particularly preferably 2 to 4).

Another embodiment of the alkoxylation is the use of mixtures of alkylene oxides, preferably the mixture of ethylene oxide and propylene oxide. Very particularly preferred for the purposes of the present invention are low-ethoxylated fatty alcohols having 1 to 4 ethylene oxide units (EO), in particular 1 to 2 EO, for example 2 EO such as Na-C ₁₂ -C ₁₄ fatty alcohols + 2 EO sulfate.

The cleaning agent according to the invention, in particular a hand dishwashing detergent, contains one or more fatty alcohol ether sulfates in an amount of 5 to 20 wt .-%, in particular from 6 to 16 wt .-%, based on the total weight of the cleaning agent.

The total surfactant content of the cleaning agent according to the invention is preferably in the range of 5.2 to 40 wt .-%.

According to the invention, the cleaning agent furthermore contains at least one amylase which has at least 90% sequence identity over the entire length of the amino acid sequence given in SEQ ID NO: 1 or SEQ ID NO: 2. In various embodiments, the amino acid sequence has at least 90.5, 91, 91.5, 92, 92.5, 93, 93.5, 94, 94.5, 95, 95.5, 96, 96.2, 96.4 , 96.6, 96.8, 97.0, 97.2, 97.4, 97.6, 97.8, 98.0, 98.2, 98.4, 98.6, 98.8, 99 , 0, 99.1, 99.2, 99.3, 99.4, 99.5, 99.6, 99.7, 99.8, 99.9 or 100.0% sequence identity to that shown in SEQ ID NO : 1 or SEQ ID NO: 2 indicated over the entire length amino acid sequence. In various embodiments, the amylase consists of such a sequence, in particular from the sequence given in SEQ ID NO: 1 or in SEQ ID NO: 2.

In further embodiments, variants of these amylases are also detected, which are shorter than the sequences described above and / or C-terminal or are extended by 1-50 amino acids and / or have insertions, substitutions or deletions, but the amylase activity is retained, especially at least 70% of the activity of the unreduced / unextended / non-mutated enzyme.

In various embodiments, the cleaning agent may also contain a combination of two or more amylases, each being as defined above. In particular, can a first amylase which has at least 90% sequence identity to the full length amino acid sequence given in SEQ ID NO: 1, and a second amylase which has at least 90% sequence identity to the amino acid sequence given in SEQ ID NO: 2 over the amino acid sequence entire length. All the embodiments generally disclosed above in connection with the amylases, in particular with regard to sequence identity and variants, are also applicable to any of the amylases in such a combination of two amylases.

The total content of these amylases is 1 × 10 ^-8 to 5 wt .-% based on active protein. More preferably, the amylases are in an amount of 1 × 10 ^-7 -3 wt%, from 0.00001-1 wt%, from 0.00005-0.5 wt%, from 0.0001 to 0.1 wt .-% and particularly preferably from 0.0001 to 0.05 wt .-% in inventive compositions, each based on active protein.

The protein concentration can generally be determined by known methods, for example the BCA method (bicinchoninic acid, 2,2'-biquinolyl-4,4'-dicarboxylic acid) or the biuret method ( Gornall AG, CS Bardawill and MM David, J. Biol. Chem., 177 (1948), pp. 751-766 ). Determination of the active protein concentration in this regard may be achieved by titration of the active sites using a suitable irreversible inhibitor and determination of residual activity (see M. Bender et al., J. Am. Chem. Soc., 88, 24 (1966), p -5913).

The determination of the identity of amino acid sequences is carried out by a sequence comparison. This sequence comparison is based on the BLAST algorithm established and commonly used in the prior art (see, for example, Altschul, SF, Gish, W., Miller, W., Myers, EW & Lipman, DJ (1990) "Basic local alignment search tool Biol. 215: 403-410, and Altschul, Stephan F., Thomas L. Madden, Alejandro A. Schaffer, Jinghui Zhang, Hheng Zhang, Webb Miller, and David J. Lipman (1997): " Gapped BLAST and PSI-BLAST: a new generation of protein database search programs ", Nucleic Acids Res., 25, pp.3389-3402) and is principally accomplished by associating similar sequences of amino acids in the amino acid sequences. A tabular assignment of the respective positions is referred to as alignment. Another algorithm available in the prior art is the FASTA algorithm. Sequence comparisons (alignments), in particular multiple sequence comparisons, are created with computer programs. For example, the Clustal series (see, for example, Chenna et al., 2003: Multiple sequence alignment with the Clustal series of programs, Nucleic Acid Research 31, 3497-3500), T-Coffee (see, for example, Notredame et al (2000): T-Coffee: A novel method for multiple sequence alignments, J. Mol. Biol. 302, 205-217) or programs based on these programs or algorithms. Also possible are alignment comparisons (alignments) with the computer program Vector NTI® Suite 10.3 (Invitrogen Corporation, 1600 Faraday Avenue, Carlsbad, California, USA) with the default parameters whose AlignX module for sequence comparisons is based on ClustalW. Unless otherwise specified, the sequence identity given herein is determined by the BLAST algorithm.

Such a comparison also allows a statement about the similarity of the compared sequences to each other. It is usually given in percent identity, that is, the proportion of identical amino acid residues at the same or in an alignment corresponding positions. The broader concept of homology involves conserved amino acid substitutions in the consideration of amino acid sequences, that is, amino acids with similar chemical activity, as these usually perform similar chemical activities within the protein. Therefore, the similarity of the sequences compared may also be stated as percent homology or percent similarity. Identity and / or homology information can be made about whole polypeptides or genes or only over individual regions. Homologous or identical regions of different amino acid sequences are therefore defined by matches in the sequences. Such areas often have identical functions. They can be small and contain only a few amino acids. Often, such small regions exert essential functions for the overall activity of the protein. It may therefore be useful to relate sequence matches only to individual, possibly small areas. Unless otherwise indicated, identity or homology information in the present application, however, refers to the total length of the particular amino acid acid sequence indicated.

The amylase is preferably a mature amylase, i. to the catalytically active molecule without signal and / or propeptide (s). Unless otherwise stated, the sequences given refer to each mature (processed) enzymes.

The agent according to the invention contains one or more betaines in an amount of 0.5 to 10% by weight, more preferably 1 to 8% by weight, in particular 2 to 5% by weight, based on the total weight of the cleaning agent.

In a preferred embodiment of the invention, the agent according to the invention is a hard surface cleaner, such as a liquid manual dishwashing detergent or an all-purpose cleaner. In particular, it is preferably a hand dishwashing detergent which is used for manual dishwashing. In addition to linear alkylbenzenesulfonate, fatty alcohol ether sulfate, the specific amylase and the betaine, the agent according to the invention may also contain one or more anionic surfactants and / or nonionic surfactants and / or one or more amphoteric surfactants and / or one or more cationic surfactants. These are listed below as a possible component of (e) so as additives and / or additives.

Additives and / or Additives (e)

The agent according to the invention can contain up to 20% by weight, based on the total weight of the cleaning agent, of additives and / or additives. Suitable additives and additives are listed below.

Substances which also serve as ingredients of cosmetic products are hereinafter referred to as appropriate according to the International Nomenclature Cosmetic Ingredient (INCI) nomenclature. Chemical compounds carry an INCI name in English. The following are as far as possible given their German translation and, if necessary, the English name in brackets. The INCI name can be found in the International Cosmetic Ingredient Dictionary and Handbook, 7th Edition (1997), published by The Cosmetic, Toiletry and Fragrance Association (CTFA), Washington D.C. (USA) is issued. The indication CAS means that the following sequence of numbers is a name of the Chemical Abstracts Service.

The anionic surfactants which are furthermore preferably preferred, in particular in hand dishwashing detergents, include alkali metal salts of the fatty alcohol sulfate. The cleaning agent according to the invention may preferably contain from 0.05 to 5% by weight, in particular from 0.1 to 3% by weight, particularly preferably from 0.3 to 1% by weight, of the alkali metal salt of the fatty alcohol sulfate, of another anionic surfactant on the total weight of the detergent. This can be used as an additive, which affects the foam volume. It has been found that in the case of water with a water hardness of 16 to 20 ° dH, ie in the case of hard water, a proportion of 0.05% by weight and in particular a proportion of 0.1% by weight is sufficient compared to soft water to achieve only slightly reduced foam volume. The harder the water is, the higher the proportion of fatty alcohol sulphate should be. However, a proportion of more than 3 wt .-%, in particular more than 5 wt .-% provides no further stabilization of the foam even with very hard water having a water hardness of 20 to 32 ° dH. It has been found that a proportion by weight of 0.3 to 1 wt .-% is sufficient to the desired foam volume in both hard and very hard water having a water hardness of 16 to 32 ° dH, in particular from 20 to 32 ° to get dH. A higher dosage of the alkali salt of the fatty alcohol sulfate would therefore only lead to an increase in costs, but not to a significantly larger foam volume.

The fatty alcohol sulfate according to the invention preferably has 12 to 14 C-atoms, in particular 13 C-atoms. The alkali salt is preferably a sodium salt.

microcapsules

It may be desirable to maintain the skin feel positive influencing agents or other sensitive agents, such as perfumes, spatially separated from the actual agent until use. An elegant method for incorporating such sensitive, chemically or physically incompatible or volatile ingredients is the use of microcapsules in which these ingredients are stored stable and transport stable and from which they are released to or during use mechanically, chemically, thermally or enzymatically , In a preferred embodiment, therefore, one or more of the skin feel positively affecting agents and / or perfumes and / or fragrances is wholly or partially incorporated into microcapsules.

Microcapsules are finely dispersed liquid or solid phases coated with film-forming polymers, in the preparation of which the polymers precipitate on the material to be enveloped (active ingredient) after emulsification and coacervation or interfacial polymerization. In this case, the active ingredient is shell-shaped enveloped by a solid membrane ( Microcapsule in the strict sense) or enclosed by a matrix (microsphere or sphere). In the following, the term microcapsule is used in a summarized sense for both variants. Such capsules are usually microscopically small (<50 microns) and are sometimes referred to as nanocapsules or nanospheres, they can be like powder drying. However, larger capsules or pearls visible to the naked eye (> 0.5 mm) filled with active ingredients can also be produced. These provide, incorporated in the hand dishwashing detergent according to the invention, an additional visual appeal when the capsules are suspended stable distributed on average, which can be realized by the selection of suitable surfactants and thickening agents and the setting of a suitable viscosity.

As microcapsules, it is possible to use all surfactant-stable capsules and capsule materials or spheres and spheroidal materials available on the market, such as, for example, the commercially available Primasphere® (chitosan and agar or carboxymethylcellulose) and Primasponge® (alginate, chitosan, agar) from BASF, Hallcrest Microcapsules® (gelatin, gum arabic) from Hallcrest, Inc.

The microcapsules may have any shape in the production-related framework, but they are preferably egg-shaped or ellipsoidal or in particular approximately spherical. Depending on the active substance and application, the diameter along its greatest spatial extent can be on average between 100 nm (visually not recognizable as a capsule) and 10 mm. The preferred average diameter is in the range between 0.1 mm and 7 mm, particularly preferred are microcapsules with an average diameter between 0.4 mm and 5 mm. To improve the appearance, dyes, color pigments or pearlescent components can also be added.

The release of the active ingredient from the microcapsules can be done mechanically both by grinding the microcapsules during the cleaning process as well as by breaking up by means of a suitable metering device. Other options are the release of the active ingredient by changing the temperature (introduction into warm rinsing water), by shifting the pH, changing the electrolyte content, etc.

If microcapsules are used, their content is usually from 0.01 to 10% by weight, preferably from 0.1 to 5% by weight, in particular from 0.2 to 3% by weight and very preferably from 0.3 to 2% by weight -%, wherein the cleaning agent according to the invention may contain only similar microcapsules or else mixtures of different types of microcapsules.

To adjust and / or stabilize the pH, the composition according to the invention may contain one or more buffer substances (INCI: Buffering Agents), usually in amounts of from 0.001 to 5% by weight, preferably 0.005 to 3% by weight, in particular 0.01 to 2 wt .-%, particularly preferably 0.05 to 1 wt .-%, most preferably 0.1 to 0.5 wt .-%, for example, 0.2 wt .-%. Preference is given to buffer substances which are at the same time complexing agents or even chelating agents (chelating agents: INCI: chelating agents).

The cleaning agent may further contain hydrotropes. These are solubilizers. Suitable hydrotropes are, for example, urea, butyl glycol or aliphatic short-chain anionic or amphoteric solubilizers.
