Description

The The present invention relates to coated core-shell aggregates for washing or detergent and a process for producing the same. The aggregates which can be produced by agglomeration can be used in the washing or cleaning agent industry be used and used advantageously.

Granulation operations are in the most different branches of industry prior art, and there is a big one Number of standard monographs and patent literature on this Theme. In the context of the present invention, it is of Meaning that over the Granulation process delivered an important contribution to product design can be.

By the enormous variety of for all needs of the daily The consumer often sees the life offered goods in front of it Problem posed, from a barely to survey variety of Just to select the product that suits his needs most corresponds. Here the product design can be the consumer make the purchase decision easier.

The Buying decision is generally based on very different Criteria, but above all the price of the presented goods and their quality. As an additional Criterion for the purchase decision, however, the product design is becoming increasingly important. The consumer wants usually use a product, which is also its aesthetic Appeals to. That's why many products come with equipped with visually appealing packaging. Also the product in itself is of great Interest, for example regarding its color and shape. about the shape of the product can be the aesthetic one Feeling the consumer are particularly easily addressed. As an example, here are powdered detergents and / or cleaning agents called. A visually appealing product from this area For example, a detergent powder that is made exclusively from almost spherical Particles exists. Such a detergent powder of almost the same and almost spherical Particles indicates due to its high symmetry and its homogeneous Appearance in the eyes of the consumer on high care in the preparation and high competence in the processing of washing powder out while a powder that consists of very irregularly shaped particles, does not trigger corresponding positive associations among the consumer.

In front This background was the asked to the present invention Task in the provision of largely aesthetically pleasing granules.

This object is achieved by the subject matter of the invention, which is a core-shell aggregate for detergents or cleaners, which consists of a core and the core surrounding particles, wherein the particles surrounding the core have a particle diameter d ₅₀ , the maximum one Tenth of the particle diameter d _{50 of} the core particles is, but greater than 2 microns, wherein preferably the core particles in particular less than 75 wt .-% and the particles to be added make up more than 25 wt .-% of the core-shell aggregate forming solids with the proviso that at least one coating is applied to the core-shell aggregate from the outside.

Of course they are here not far more diverse Combinations possible, which here for reasons the clarity not explicitly listed, but directly to the skilled person are reasonable.

These Freedom in the design of the coated particles leads to so good as unsurpassable options for the Use of the coated core-shell aggregates in a particle collective, for example a washing powder, wherein the coated core-shell aggregates can also be the sub-collective of an entire collective. The Release delay of Coated core-shell aggregates can now be fine-tuned as desired. in addition comes that the Delay delay over the just described actuators even finer differentiable is over and over the porosity or density of the core. One higher porous or less dense core material dissolves faster than one less porous or higher compacted nuclear material.

• a) Ein Teilchenkollektiv beschichteter Kern-Schale-Aggregate (Waschpulver) kann z.b. aus 2 Sorten beschichteter Kern-Schale-Aggregate bestehen. Die Sorte 1 zeichnet sich, dadurch aus, daß sie einen hydrophob imprägnierten Kern, eine hydrophobe Beschichtung und eine hydrophob gebundene Schale aufweist. Der Kern ist zudem wenig porös oder höher verdichtet.

For the sake of clarity, only two cases have been singled out for the sake of clarity, although the expert is aware that he has manifold possibilities of variation:

• a) A particle collective coated core-shell aggregates (washing powder), for example, be of 2 types be layered core-shell aggregates exist. The variety 1 is characterized by the fact that it has a hydrophobically impregnated core, a hydrophobic coating and a hydrophobically bound shell. The core is also less porous or more compacted.

The Grade 2 is characterized by the fact that they are hydrophilically impregnated Core, a hydrophilic coating and a hydrophilic bound Shell has. The core is also porous or slightly dense.

at the application of such a washing powder are now two categories of particles with completely opposite dissolution behavior, namely one Category of particles with a very pronounced dissolution delay (here grade 1) as well as another category of particles with very pronounced release speed (here Variety 2). Conveniently, would be in the Particle Type 1 particles incorporate such active substances which are immediate should be released at the beginning of a washing process or act should, while the particles of grade 2 contains such active substances, which only in late Stages of a wash cycle, e.g. care components or aftertreatment components.

• b) Ein Teilchenkollektiv beschichteter Kern-Schale-Aggregate (Waschpulver) kann z.b. aus 1 Sorte beschichteter Kern-Schale-Aggregate bestehen, welche sich dadurch auszeichnet, daß sie einen hydrophob imprägnierten Kern, eine hydrophile Beschichtung und eine hydrophob gebundene Schale aufweist. Der Kern ist zudem wenig porös oder höher verdichtet.

As one skilled in the art can readily appreciate, there are many possible variations between these two extremes to adapt the release behavior to the particular needs.

• b) A particle collective of coated core-shell aggregates (washing powder) may, for example, consist of 1 type of coated core-shell aggregates, which is characterized in that it has a hydrophobically impregnated core, a hydrophilic coating and a hydrophobically bound shell. The core is also less porous or more compacted.

One such coated core-shell aggregates would be very fast, i. immediate at the beginning of a wash, release those actives which the coating comprises. The active ingredients of the shell would be there subsequently slowly released. The active substances of the nucleus would then be released later.

As the person skilled in the art immediately recognizes, this is freely adjustable here dissolution behavior also for the production of farm bodies, e.g. Tablets perfectly applicable. Take, for example, just an illustrative example to deliver the previously mentioned particle collective coated Core-shell units (Washing powder), which consists of 2 types of coated core-shell aggregates exists, the variety 1, characterized by the fact that they have a hydrophobic impregnated Core, a hydrophobic coating and a hydrophobically bound Shell, wherein the core is also less porous or more compacted, and wherein the variety 2 is characterized by the fact that they have a hydrophilic impregnated Core, a hydrophilic coating and a hydrophilic bound Shell, wherein the core is also porous or slightly compacted, this results in excellent (detergents and cleaning agents) tablets produce. In such a tablet would be the particles of the variety 2 dissolve rapidly on contact with water, so that the tablet disintegrates very quickly or their integrity loses. The tablet disintegrates thereby releasing those contained in the particles of the variety 2 Active substances in the particles of the variety 1, which then later their Release active substances. Again, one is the expert directly given reasonable variation, with which the dissolution and Control disintegration behavior of tablets almost arbitrarily.

For example can the cores of the coated core-shell aggregates also decay accelerator contain, for example, substances that have a large adsorption capacity for water possess (for example, starch, Cellulose derivatives, alginates, dextrans, cross-linked polyvinylpyrrolidone, Casein derivatives, etc.) and / or in particular gas-evolving substances (such as sodium bicarbonate and citric or tartaric acid, etc.), so that one Shower effect or sparkling effect occurs. Contained the particles of grade 2 such decay accelerators, so would the molding still disintegrate faster.

One Another object of the invention is therefore a molding, preferably Tablet containing agents according to the invention.

the Design freedom of the expert are now hardly more limits. Of course, let the coated core-shell aggregates are also advantageous in Pouches, bags or sacks apply. Another object of the invention is a pouch, Bag or bag containing agents according to the invention.

One Another object of the invention is a detergent or cleaning agent containing agents according to the invention, in particular a detergent containing care components.

• (a) Reinigungskomponente, enthaltend beispielsweise Tenside wie vorzugsweise Alkansulfonate, Alkylethersulfate, Alkylpolyglucoside und/oder Cocoamidopropyl-Betain
• (b) Klarspülkomponente, enthaltend beispielsweise nichtionische Tenside, vorzugsweise auf Fettalkohol-Basis, insbesondere mit Zusätzen niederer Alkohole als Lösungsvermittler und vorteilhafterweise von Citronensäure
• (c) Enthärtungskomponente, enthaltend beispielsweise Phosphonat, Polycarboxylat, Natriumgluconat, Ethylendiamintetraessigsäure (EDTA), Nitrilotriessigsäure (NTA) und/oder Aluminiumsilicaten (Zeolithen)
• (d) Optional: weitere Bestandteile wie vorzugsweise Silber-/Glasschutz-Komponente

Another object of the invention is a detergent, preferably dishwashing detergent, containing

• (A) cleaning component containing, for example, surfactants such as preferably alkanesulfonates, alkyl ether sulfates, alkyl polyglucosides and / or cocoamidopropyl betaine
• (b) Rinse aid component containing, for example, nonionic surfactants, preferably on a fatty alcohol basis, in particular with additions of lower alcohols as solubilizers and advantageously of citric acid
• (c) softening component containing, for example, phosphonate, polycarboxylate, sodium gluconate, ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA) and / or aluminum silicates (zeolites)
• (d) Optional: other ingredients such as preferably silver / glass protection component

One Another object of the invention is an agglomerate / granules (i.e. an aggregate), which is a multi-fuel system, the contained Substances are arranged in at least 3 different phases, preferably in the phases core, shell and coating, wherein In particular, the chemical composition of the phases is different.

But the shown fine adjustment possibilities of the active substance release go even far over the previously described.

To a further preferred embodiment the coating is pH and / or temperature and / or ionic strength sensitive or contains pH and / or Temperature and / or ionic strength-sensitive Materials. According to another embodiment, the shell is pH and / or temperature and / or ionic strength-sensitive or contains pH and / or Temperature and / or ionic strength-sensitive Materials. In another embodiment, the core is pH and / or temperature and / or ionic strength-sensitive or contains pH and / or Temperature and / or ionic strength-sensitive Materials.

in the Following is the terminology of the pH and / or temperature and / or ionic strength sensitivity predominantly explained using the example of the coating. However, it is clear to the person skilled in the art that he will readily do the same Mechanisms also on the preparation of core and shell can apply. The core may e.g. a granule be, which consists of subparticles, which by a pH and / or Temperature and / or ionic strength-sensitive Material held together. Under adjustable conditions concerning pH and / or temperature and / or ionic strength the core thus its integrity lose, so crumble. The shell may e.g. with a pH and / or Temperature and / or ionic strength-sensitive Granulation on have been applied to the core. Under adjustable conditions concerning pH and / or temperature and / or ionic strength the shell thus their integrity lose and dissolve.

• (a) eine Änderung (Zunahme oder Abnahme) der Löslichkeit (vorzugsweise in Wasser) erfährt/erfahren; und/oder
• (b) eine Änderung (Zunahme oder Abnahme) der Diffusionsdichte erfährt/erfahren; und/oder
• (c) eine Änderung (Beschleunigung oder Verlangsamung) der Lösungskinetik erfährt/erfahren; und/oder
• (d) eine Änderung (Zunahme oder Abnahme) der mechanischen Stabilität erfährt/erfahren.

By the term pH sensitivity, temperature sensitivity and / or ionic strength sensitivity is meant that the coating or the materials forming the coating with a change in the pH, the temperature and / or the ionic strength in the environment, which is exposed to the coating (eg a wash liquor),

• (a) undergoes a change (increase or decrease) in solubility (preferably in water); and or
• (b) undergoes a change (increase or decrease) in diffusion density; and or
• (c) undergoes a change (acceleration or deceleration) in the solution kinetics; and or
• (d) undergoes a change (increase or decrease) in mechanical stability.

For the temperature sensitivity there are in addition to the above options (a) to (d), the additional option (E), after the coating or the coating forming Materials in case of a change the temperature is a change of the state of matter from solid to liquid or vice versa, i.e. the materials melt or solidify.

When therefor suitable coating material may in the context of the invention All those materials whose integrity is a function of temperature serve and / or the pH and / or the ionic strength or even such materials, the nature of mechanical stress as e.g. in the course of an automatic Laundry process occur, their integrity to lose.

Advantageously, the pH sensitivity of the coating can be utilized. For example, the coating may be designed to completely or partially dissolve when the pH falls below a critical level. This can be done in the example of a washing process when the alkaline wash water is removed from the machine and fresh water introduced into the machine, preferably in the rinse of the Washing process. Upon contact with the fresh water, the coating then lose its integrity, in whole or in part, making the core-shell aggregate water-penetrable. The pH in question, in which the coating completely or partially disintegrated, can be adjusted as desired, so that the material, for example, then completely or partially loses its integrity if the pH z. B. falls below 9.0, but remains substantially inert, as long as the pH is above 10, 0.

Of the Term "inert" according to the invention in the usual Understood meaning, so in the way that a physical or chemical Reacting the material of the coating with the ambient environment essentially not done, but the material of the coating physically and chemically resistant opposite this is so that that Core-shell aggregate from penetration through the environment, e.g. the wash liquor is substantially protected.

In a particularly preferred embodiment the coating consists of at least 2 layers, with the outermost layer designed so that they in, preferably cold, water at pH values below a maximum of 6, preferably below a maximum of 7, in particular below a maximum of 8, essentially is inert, but in, preferably warm, water at pH values above at least 11, preferably above at least 10, in particular above at least 9, their integrity in whole or in part loses, and that the Innermost layer is designed so that they in, preferably warm, Water at pH values above at least 11, preferably above of at least 10, especially above at least 9, substantially is inert, but in, preferably cold, water at pH below a maximum of 6, preferably below a maximum of 7, in particular below a maximum of 8, their integrity completely or partially loses.

These Design considered the special requirements at the beginning of the washing process. At the start come detergent for a, albeit short, period of time in contact with, preferably cold, non-alkaline Water and thus meets similar Conditions, as in the rinse cycle to rule. So here's an outermost layer advantageous, which is substantially inert to these conditions. The outermost layer is the one that directly adjoins the surrounding fluid. Under the extreme Layer can in the direction of the core-shell aggregate one or more layers follow. The last following layer is the innermost layer. This separates the core-shell aggregate preferably of all further layers or the ambient fluid. If the coating is just one Layer, then the term "outermost" or "innermost" is obsolete. If the coating consists of only one layer, then it is preferred designed so that they in, preferably warm, water at pH values above at least 11, preferably above at least 10, in particular above of at least 9, is substantially inert, but in, preferably cold, water at pH values below a maximum of 6, preferably below a maximum of 7, in particular below a maximum of 8, their integrity completely or partially loses. In this way you can reach easy Kind a good protection of the core-shell aggregate. As the flushing process short-lived and the alkaline components Detach the detergent very quickly, is already during the flushing process alkaline water, so that also a coating that only consists of one layer, which in the plane mentioned sense is pH-sensitive, in the context of the invention, well-effective is, since it only a few seconds of non-alkaline water is wetted.

To the short moment of the flushing process is over, is therefore alkaline, possibly heated water before. In this (possibly warm) water at pH values above advantageously at least 11, preferably above at least 10, in particular above at least 9, loses the outermost coating (in multilayer Coating) wholly or partly their integrity. The innermost layer, on the other hand, would be designed so that they in (possibly warm) water at pH values above advantageously at least 11, preferably above at least 10, in particular above of at least 9, is substantially inert. The innermost layer advantageously comes in contact with nature only then the wash liquor, or water, when the outermost layer is wholly or partially partially lost, that is, when (possibly warm) alkaline Water is present. Under these conditions, then is the innermost Layer advantageously opposite the wash liquor is substantially inert and thus protects the core sufficiently from direct contact with the water. In the rinse is the previously completely removed alkaline wash with fresh non-alkaline water replaced. Under these conditions, so in, preferably cold, water at pH values below maximum 6, preferably below a maximum of 7, in particular below of a maximum of 8, now advantageously loses the innermost Layer their integrity in whole or in part, so that Core-shell aggregate can be penetrated by water.

Of the For the sake of clarity, it should be noted that what has just been described is itself only to a preferred embodiment relates to the invention.

Materials, as coating materials, in particular in the sense of such embodiments can be used are any inorganic and / or organic substances and / or Mixtures of substances, but especially polymers, copolymers, polymers Composites, preferably those which are pH, temperature and / or ionic strength-sensitive are.

When Coating materials, preferably in the sense just described, For example, waxes and / or resins come into consideration, for. B. beeswax, Benzo resin, carnauba wax, candelilla wax, coumarone-inden resin, Copal, shellac, mastic, polyethylene wax oxidates or sandarak resin. Likewise, too Paraffins or gelatin, in particular cellulose ethers suitable Coating materials.

Especially preferred as coating materials are polymers and / or Copolymers which have film-forming properties and preferably from aqueous dispersion can be inserted. Organic solvents Although they are also preferred, can but for many reasons (Flammability, toxicity etc) also detrimental in the production of pH-sensitive coatings. Aqueous dispersions stand out by easy handling and the avoidance of all toxicological Problems out. The decisive size for the film-forming properties is the glass transition temperature the film-forming polymer and / or copolymer. Above the glass temperature the polymer or copolymer is elastic, meltable and flowable while it is below the glass transition temperature brittle becomes. Only above the glass transition temperature For example, the polymer can be easily processed as it is for forming a film overlay is required. The glass transition temperature can be made softening by the addition of low molecular weight substances Properties, the so-called plasticizers are influenced. In addition to the polymer can So in the watery Dispersion can also be used plasticizer. As plasticizers are suitable for all substances which used the glass transition temperature of the preferably reduce pH-sensitive, polymers and / or copolymers. The polymer can thus at lower temperatures, possibly even at Room temperature are applied. Particularly preferred plasticizers are citric acid esters (preferably tributyl citrate and / or triethyl citrate), phthalic acid ester (preferably dimethyl phthalate, diethyl phthalate and / or dibutyl phthalate), Esters of organic polyhydric alcohols (preferably glycerol triacetate), Polyalcohols (preferably glycerol, propylene glycol) and / or polyoxyethylene glycols (preferably polyethylene glycol). The plasticizer is intercalated the polymer chains, increased thereby the mobility, lowers the interactions and avoids by reducing the brittleness Abrasion and cracks in the film.

Especially It is advantageous if the coating material is a polyacrylate and / or a derivative thereof and / or a corresponding copolymer based on acrylic esters or acrylic acids and other monomers. In particular, copolymers of acrylamide and acrylic acid and / or derivatives thereof are for the coating materials according to the invention advantageous.

The Principle of pH-dependent Water is usually based on protonation or deprotonation of functional Groups of polymer molecules, whereby their state of charge changes accordingly. The polymer can now be advantageously designed so that it is in the at certain pH stable charged state dissolves in water, in the uncharged State at a different pH, however, fails. In the context of the present It is invention, at least what the innermost layer of the coating is concerned, that the used according to the invention Polymers that make up the innermost layer of the coating at least partially, at a higher pH, a lower one Water than at lower pHs or even at a higher pH are water insoluble. In a preferred embodiment The invention is also advantageous, at least when a Coating consisting of a single layer is present that can be used according to the invention Polymers from which the coating consists at least partially can, at a higher pH a lower water solubility than are water insoluble at lower pHs or even at a higher pH.

Vice versa it is within the scope of a preferred embodiment of the present invention Invention advantageous, at least what the outermost layer of the coating is concerned that the polymers usable according to the invention, from which the outermost layer the coating may at least partially exist, in a Lower pH have a lower water solubility than at higher pH values or even water insoluble at a lower pH.

Polymers with pH-dependent solubility are known in particular from pharmacy. Here, for example, acid-insoluble polymers are used to give tablets an enteric coating, but soluble in the intestinal juice. Such acid-insoluble polymers are usually based on derivatives of polyacrylic acid, which is present in the acidic region in undissoziierter and thus insoluble form, in the alkaline range, more typical but neutralized at pH 8 and goes into solution as polyanion. Polymers of similar type, which are tailored to the particular pH requirements of the machine washing process, are advantageous for the configuration of the outermost layer of the coating according to a preferred embodiment, as long as the coating is multi-layered. This layer, preferably the outer layer, can advantageously be substantially inert in the neutral to acidic form, but advantageously dissolve completely or partially in the alkaline, ie at pH values above 11, preferably above 10, in particular above 9. If the coating is not multi-layered, then polymers of this type are rather not advantageous for the design of the coating.

According to one preferred embodiment, is the multilayer coating, especially the outermost layer the coating so that they at least partially of polyacrylic acid and / or Derivatives of polyacrylic acid which at pH values above at least 11, preferably above of at least 10, especially above at least 9 as polyanion in solution goes.

Also for the reverse case - soluble in acidic area, insoluble in the alkaline range - are known in the art examples. These substances in which the polymer molecules mostly amino-substituted functional groups or side chains are worn e.g. used for the preparation of gastric juice-soluble tablet coatings. They solve usually at pH values below 5 on. Polymers in which the solubility change from soluble after insoluble at higher pH levels are not known from pharmacy, as these pH values physiologically have no meaning.

Particularly preferred substances in the context of the present invention are basic, preferably film-forming, (co) polymers which have amino groups or aminoalkyl groups. Comonomers can be, for example, conventional acrylates, methacrylates, maleinates or derivatives of these compounds. A particularly suitable aminoalkyl methacrylate copolymer marketed by Rohm and carries the trade name / mark Eudragit ^®.

In a preferred embodiment contains the coating at least partially a substance from the group Amino groups, imino groups and / or pyridine groups Contains polymers and / or copolymers, wherein the base exponent this substance between 2 and 9, preferably between 2.5 and 8.5, more preferably between 3 and 8, even more preferably between 3.5 and 7.5, but especially between 4 and 6.

The base exponent (pK _B ) is the negative decadic logarithm of the base constants [pK _B = -Ig K _B , with K _B = base (dissociation) constant]. These terms are familiar to those skilled in the art.

Of the Base exponent is an equilibrium constant that varies with temperature and / or ionic strength can change. The stated values refer to a temperature of T = 25 ° C. The relevant known Literature can corresponding pK values are taken. Likewise, the relevant known Literature information about Methods for determining the pK values.

at particularly preferred means, the coating is at least partially from a copolymer of basic monomers such as dialkylaminoalkyl (meth) acrylates with acrylic acid esters.

Also agents in which the coating at least partially of an ampholytic polymer, preferably a copolymer of basic monomers such as dialkylaminoalkyl (meth) acrylates with substituted or unsubstituted acrylic acids and / or (meth) acrylic acids and / or their esters with aliphatic C ₁ -C ₈ Alcohols, constitute a preferred embodiment of the invention.

The Amino groups, imino groups and / or pyridine groups Polymers and / or copolymers contain in a preferred embodiment alkyl-substituted nitrogen groups, preferably alkyl-substituted Amino groups, especially tertiary Amino groups which have a branched or unbranched alkyl substituent with up to 22 carbon atoms, preferably 2-20, in particular of 4-18 C atoms, for example 12 C atoms carry.

The Alkyl-substituted nitrogen groups in the (co) polymer contribute to this to improve the film-forming properties of the (co) polymer.

For the application in addition to the thermodynamic solubility and the dissolution kinetics of Coating of importance. The solution kinetics of the coating materials used according to the invention is advantageously pH-dependent down to the alkaline range, ie the coating materials are for example significantly longer stable at a pH of 10 than at a pH of 8.5, although they are at both pH Values are thermodynamically soluble.

In a further embodiment of the present invention, therefore, polymers are used whose water solubility changes between the pH of 7 and the pH of 6 and which are less soluble at higher pH values than at lower pH. Suitable polymers contain, as already described above, basic groups, for example primary, secondary or tertiary amino groups, imino groups, amido groups or pyridine groups, generally those groups which have a quaternizable nitrogen atom. The quaternizable nitrogen atoms are protonated upon lowering of the pH, whereby the polymer becomes soluble. At higher pH values, the molecule is in the uncharged state and is therefore insoluble. In general, the transition - referred to below as "switching point" - is dependent on the pK _B value of the basic groups and also dependent on their density along the polymer chain, in the range of acidic pH values. The coating materials therefore preferably also comprise a polymer in which the switching point lies in a range between pH 6 and 7.

In principle, this shift in the switching point of a polymer suitable for the purposes of the present invention succeeds as follows: Depending on the pK _B value of the functional groups of the polymer, the state of charge of the polymer in solution only very slightly changes in the region of higher pH values. Therefore, it is necessary to decisively influence the solubility of the polymer with little change in the state of charge of the polymer. The polymer can thus have exactly such a hydrophilicity that it is insoluble in completely uncharged state, but at an already low charge, for example by protonation, becomes soluble.

In In practice, the person skilled in the art will be familiar with the general knowledge here for coating pharmaceutical substances such as Take, for example, tablets and coated tablets with gastric juice-soluble coatings. A well-known class of coating materials which at pH values less than 6, preferably smaller than 7 or in particular smaller 8, can be used Copolymers of basic monomers, water-insoluble monomers and if desired water-soluble Monomers. Examples of basic monomers are esters the acrylic acid and methacrylic acid and the alkylaminoalkyl acrylates or methacrylates in particular Dimethylaminoethyl acrylate in question. Other suitable basic monomers are vinyl pyrridine or substituted with alkylaminoalkyl groups Acrylic or methacrylamide derivatives. Water-insoluble monomers become esters the acrylic acid or methacrylic acid with alcohols having 1 to 8 C atoms, in particular the methyl esters, Ethyl ester, butyl ester or 2-hexyl ethyl ester used.

When water-soluble Monomers can Substances such as acrylamide, methacrylamide, vinylpyrrolidone or hydroxyethylacrylates or methacrylates find use.

• • Copolymerisation eines Monomers mit basischer Funktion mit einem hydrophileren Monomer. Durch das Einbauverhältnis der jeweiligen Comonomeren wird der Schaltpunkt beeinflußt.
• • Hydrophilierung des basische Gruppen tragenden Polymers durch eine polymeranaloge Umsetzung. Durch den Modifikationsgrad wird der Schaltpunkt beeinflusst.

To adjust the hydrophilicity, the following methods can also be used:

• • Copolymerization of a monomer with a basic function with a more hydrophilic monomer. Due to the incorporation ratio of the respective comonomers, the switching point is influenced.
• Hydrophilization of the basic group-bearing polymer by a polymer-analogous reaction. The degree of modification influences the switching point.

In addition to simple hydrophilization, it is also possible to introduce basic functions of different pK _B values. Due to the ratio of both groups and the resulting hydrophilicity of the molecule, the switching point can be influenced.

One Particularly preferred polymer of this class of substance is an N-oxidized Polyvinyl pyridine.

Typical coating materials may include, for example:
10 to 60% by weight of the water-insoluble monomers,
20-80 wt .-% of the amino group-carrying monomers and
0-40% by weight of the water-soluble monomers.

According to a particular embodiment, acids such as acrylic or methacrylic acid can be used as water-soluble monomers, furthermore, N-oxides of the aforementioned amino group-carrying monomers can be used, such as vinylpyridine-N-oxide. Also, quaternized monomers, such as dialkyldiallylammonium salts or quaternization products of the abovementioned aminogruppentragenden Methacrylic and acrylic esters can be used.

Generally is to say that with increasing amount of water-insoluble Monomers also the pH rises, where a solution of the polymer occurs. The expert has the possibility in this way to set special pH values.

The The aforementioned copolymers are preferably prepared by emulsion polymerization produced, at a pH at which they are not in solution. The polymer dispersions obtained in this way are suitable for the core-shell aggregates to coat. For example, technologies are used as they are common in drug manufacturing. So be in particular in slow-running mixing tools the dispersions and the particles associated with each other, isolated and mixed dried.

It but it is also possible instead of working with the dispersions with a dissolved form.

The pH-dependent soluble Polymer can not only be used as a coating, but also as a matrix material, Binding or disintegrating agent for the actual core-shell aggregate or the shell or the core be used. It is not necessary that the Polymer at the for the polymer characteristic pH conditions for the release of the Active ingredient completely solves. It enough much more if, for example, the permeability of a Polymer film changes and e.g. the penetration of water into the formulation and a Dragging out the loosened Components through the holes or pores formed is made possible. As a result, in a further preferred embodiment, the agent according to the invention a secondary effect, e.g. the activation of a effervescent system or the swelling of a in water swellable disintegrant, in particular from the pharmaceutical industry are known for the complete Release of the detergent, rinse or cleaning active Active ingredient).

• (a) Es kann eine ausreichende Schichtdicke der Beschichtung oder ein ausreichend hohes Molekulargewicht des Polymers der Beschichtung eingestellt werden. Die Schichtdicke liegt erfindungsgemäß vorzugsweise im Bereich von der Größenordnung einer monomolekularen Bedeckung bis 50 μm. Das Molekulargewicht des Coatings des Polymers kann beispielsweise bei mindestens 50 kD liegen, bevorzugt bei mindestens 1.000 kD. Ein Wirkstoff-Verlust ist auch dadurch vermeidbar, daß dem Beschichtungsmaterial ein weiteres Polymer zugemischt wird, das die Löslichkeit des Blends herabsetzt. Beispiele solcher zusätzlicher Polymere sind allgemein solche, die weniger hydrophil/stärker hydrophob sind als das Coating-Polymer.
• (b) Es kann, wie bereits als bevorzugte Ausführungsform vorgestellt, ein mehrschichtige Beschichtung, enthaltend mindestens 2 verschieden pH-sensitive Schichten, aufgebaut werden, wobei die innerste und die äußerste Schicht den weiter oben beschriebenen pH-Erfordernissen genügen. Einem ähnlichen Prinzip folgend, kann auch eine zusätzliche, bei niedrigerer Temperatur weniger gut oder weniger schnell lösliche Schicht aufgebracht werden. Diese kann beispielsweise ein Paraffin sein, das bei Erreichen einer (erst im nachfolgenden Schritt durchlaufenen) höheren Temperatur schmilzt ("Schmelzcoating"), oder auch ein hydrophiles Polymer, das bei Erreichen einer bestimmten Temperatur löslich wird ("Polymer-Coating"). Sehr geeignet sind auch LCST-Substanzen, die später beschrieben werden.

To more reliably achieve the pH-sensitive coating which is to protect the core-shell aggregate in the early stages of the washing process, it does not dissolve in the earlier stages of the washing process, various methods can be used to reduce losses of active ingredients to avoid.

• (a) A sufficient layer thickness of the coating or a sufficiently high molecular weight of the polymer of the coating can be set. The layer thickness is according to the invention preferably in the range of the order of a monomolecular coverage to 50 microns. The molecular weight of the coating of the polymer may, for example, be at least 50 kD, preferably at least 1,000 kD. A loss of active ingredient can also be avoided by adding a further polymer to the coating material which reduces the solubility of the blend. Examples of such additional polymers are generally those which are less hydrophilic / more hydrophobic than the coating polymer.
• (b) As already presented as a preferred embodiment, a multilayer coating comprising at least two different pH-sensitive layers can be built up, the innermost and outermost layers meeting the pH requirements described above. Following a similar principle, an additional, less readily or less rapidly soluble layer at lower temperature can also be applied. This may be, for example, a paraffin which melts upon reaching a higher temperature (which is passed through in the subsequent step) ("melt coating"), or else a hydrophilic polymer which becomes soluble upon reaching a certain temperature ("polymer coating"). Also very suitable are LCST substances, which will be described later.

In another preferred embodiment The invention provides a pH-sensitive coating comprising a material coated, which in turn is temperature-sensitive. Here are LCST substances preferably used. LCST substances are substances, which have better solubility at low temperatures than at higher Temperatures. They are also called lower lower substances critical critical temperature (lower critical solubility temperature) or with low lower turbidity or flocculation point. Depending on the conditions of application should the lower critical demixing temperature between room temperature and the temperature of the heat treatment lie in the respective washing process, for example between 20 ° C and 120 ° C, preferably between 25 ° C and 100 ° C, lie, in particular between 30 ° C and 50 ° C. The LCST substances are preferably selected from alkylated and / or hydroxyalkylated polysaccharides, cellulose ethers, polyisopropylacrylamide, Copolymers of Polyisopropylacrylamids and mixtures of one or several of these substances.

Examples of alkylated and / or hydroxyalkylated polysaccharides are hydroxypropylmethylcellulose (HPMC), ethyl (hydroxyethyl) cellulose (EHEC), hydroxypropylcellulose (HPC), methylcellulose (MC), ethylcellulose (EC), carboxymethylcellulose (CMC), carboxymethylmethylcellulose (CMMC), hydroxybutylcellulose (HBC), hydroxybutylmethylcellulose (HBMC), hydroxyethyl cellulose (HEC), hydroxyethyl carboxymethyl cellulose (HECMC), hydroxyethyl ethyl cellulose (HEEC), hydroxypropyl cellulose (HPC), hydroxypropyl carboxymethyl cellulose (HPCMC), hydroxyethyl methyl cellulose (HEMC), methyl hydroxyethyl cellulose (MHEC), methyl hydroxyethyl propyl cellulose (MHEPC) and propyl cellulose (PC).

Further examples for LCST substances are cellulose ethers and mixtures of cellulose ethers with carboxymethylcellulose (CMC). Other polymers that have a lower show critical demixing temperature in water and the same are suitable, are polymers of mono- or di-N-substituted Acrylic amides with acrylates and / or acrylic acids or mixtures of each other entangled networks of the above (co) polymers. Suitable are as well Polyethylene oxide or copolymers thereof, such as ethylene oxide-propylene oxide copolymers, Graft copolymers of alkylated acrylamides with polyethylene oxide, polymethacrylic Polyvinyl alcohol and copolymers thereof, polyvinyl methyl ether, certain Proteins like poly (VATGVV), a repeating unit from the natural Protein elastin and certain alginates. Mixtures of these polymers with salts or surfactants also be used as LCST substance. By such additives or due to the degree of crosslinking of the polymers, the lower critical Demixing temperature (LCST) can be modified.

In a further preferred embodiment According to the invention, the coating consists of a temperature-sensitive Material. The ingredients of the core will be at the desired Temperatures released. The coating material may e.g. at Temperatures, for example, around 50 ° C his integrity to lose.

The Coating is done according to a further preferred embodiment of the invention to the core-shell aggregates in one possible thin, however, preferably forming a complete coating Thickness designed. The thickness is not critical as such, will but preferably limited by the requirement of the possible material-saving working and the possible requirement when in use e.g. to allow a fast or slow dissolution. simultaneously will be with as possible small thicknesses the requirement, the laundry and the fleet - and with it later also the wastewater - with as little as possible water To burden materials. Exemplary thicknesses used with advantage can be are e.g. in the range of 0.005 to 0.5 mm, more preferably in Range of 0.02 to 0.4 mm, which is for example coating weights in the range from, for example, 50 to 500 mg (weight of pure coating) results. But there are also all other thicknesses conceivable.

In a preferred embodiment contains the coating solution used for coating a pH-sensitive, preferably film-forming, polymer and / or copolymer according to the description of the description, a Plasticizer and a solvent, which is most preferably water. Furthermore, dyes can the solution added be distinguishable to the core-shell aggregates according to the invention from the rest of the detergent.

Prefers the (co) polymer is in the form of a preferably aqueous solution or preferably aqueous Dispersion applied to the core-shell aggregates. After drying the solvents remain the (co) polymers as coherent, even film on back to the cores. From solutions the film layer is preferably formed via a gel state while at Dispersions the Filmbildnerteilchen are swollen and thickening coalesce and film. By evaporation of the dispersant, the particles come into contact with each other. The plasticizer facilitates while the diffusion of the polymer beads, the at touch coalesce. The coalescence of the polymer leads to the formation of a continuous Film.

at Use of a watery solution or dispersion, the pH of the solution or dispersion to the solubility the (co) polymer adapted become. For example, it may be previously acidified if the (co) polymer preferably insoluble in basic is.

Of the Coating process can be continuous or discontinuous Procedure, ie batchwise, be executed. Should possible high throughputs achieved with average claims to completeness of the applied layer, continuous processes are preferred.

Batch process are preferably preferred when very high demands on the coating quality be put.

discontinuous Apparatuses usually consist of a vertical, slightly conical Container, thanks to various air inlets, inserts and Internals for different process variants can be adapted. The conventional Fluidized bed coating is usually operated as a top spray, in which the spray liquid is sprayed from above onto the fluidized bed. There are also there Configurations with nozzles, spray the side or bottom of the fluidized bed. particle preferably from about 200 microns up can to be coated.

One the preferred method is the Wurster method. Here parts centrally arranged riser the process space. Inside the tube there is a higher one Gas velocity, which transports the solid product upwards. In the outer ring the gas velocity is only slightly above the relaxation rate. This makes the particles circular moved vertically. Through this controlled flow of material is within short process times a more even coating achieved. Due to the high speed inside the tube do not stick the particles so easily. Particles preferably up down to 50 microns can be coated become.

One Another method uses bottom spray technology. at This technology works with a distributor plate, which is an air flow parallel to the soil surface generated so that the material to be coated on an air cushion floats. this leads to for substantial equalization of Coating compared to conventional systems.

continuous operated horizontal fluidized bed apparatus generally have a rectangular Inlet floor. In a continuous fluidized bed it comes to the plug flow. The product passes through several temperature and air separated Zones. So can also produces multilayer granules or different process steps be carried out simultaneously in an apparatus.

These and similar or other known coating processes, for example agglomeration processes, are each particularly suitable to a coating according to the invention to carry out the cores.

It Again, it should be noted that the pH and / or temperature and / or ionic strength sensitive Materials not only in the coating, but also as a matrix material, Binding or disintegrating agent for the actual core-shell aggregate, the core and / or the shell can be used. This corresponds to a preferred embodiment.

With the agent of the invention (coated core-shell aggregate) go, as already apparent was accompanied by various advantages.

So succeeds, e.g. the separation of incompatible substances through their division into the 3 phases of the coated core-shell aggregate. advantageously, are the granules of the invention free-flowing, almost spherical and therefore aesthetically very attractive. The granules are well-pourable and well after long storage pourable and show no tendency to clump. Also in storage in very huge Silos, where the granules by the dead weight very large pressures exposed, remains the excellent bulk and flowability received and the granules do not clump. There are no Separation tendencies. Even with long storage, there are no changes at the average grain size of the granules. advantageously, need the granules neither flow agent still powdering to get the excellent powder properties. Advantageously, the granules are dust-free and abrasion-resistant, even at higher Mechanical loading, the granules remain dust-free. adhesions or caking can not to be watched.

The Core-shell aggregates as such can be obtained by conventional agglomeration techniques produce. These will be described in more detail below, e.g. by buildup agglomeration or by the suspension agglomeration. In any case, the core is thereby surrounded with particles or to the Ken particles are deposited.

For agglomeration, a mixer / granulator can be used. By the term mixer / granulator is meant preferably drum and plate mixers and / or fluidized bed granulators, but also single- and two-shaft mixers with fast to slow rotating shafts and Zig-Zag mixers, especially discontinuous machines with low specific energy input. The particles in the mixer preferably move over the free fall or by introducing a thrust, throw or centrifugal force. Free-fall mixers are preferably used. In the relevant specialist literature, in particular Mixers / granulators are described in detail using mechanical process engineering. In the broadest sense, the term mixer / granulator means any apparatus suitable for mixing / granulating.

The Suspension agglomeration is a special form of structural agglomeration. The basis here is a 3-phase mixture, which consists of the to be agglomerated Good, a suspension liquid and a binding fluid which must not be miscible with each other. The binding fluid must the Own property to better wet the suspended good than the suspension liquid. The material to be agglomerated is in suspended form in the suspension liquid in front. Then the binding liquid introduced, which interacts with the Gutteilchen and leads to grain enlargement, i. there is an attachment of the surrounding particles on and around the Core. The granules formed are from the reusable suspension liquid for example, separated by a filtering device and dried if necessary. The agglomerate strength is that Result of solid bridges or bridges low volatility liquids between the particles thus held together. Solid bridges arise dissolved by crystallization Substances in the liquid bridge.

A Suspension agglomeration takes place, for example, with cyclohexane as suspension liquid and water as the binding liquid.

In a preferred embodiment The core-shell aggregates contain both skin care and / or skin-protecting and / or skin-healing active substances as well as fabric-softening quaternary ammonium compounds, preferably esterquats. The skin-protecting and / or skin-healing active ingredients are active ingredients which are the skin to confer an advantage over a mere one sensory and / or cosmetic benefit.

Of the Concept of skin healing or the attribute skin-healing in context this invention can be easiest about define the condition of healthy human skin. Healthy human Skin is characterized by its intact nature acid mantle adequate protection against microorganisms, germs and pathogens deliver that theirs buffering capacity and their alkalinity-neutralizing ability is sufficient to contain harmful influences Fluids ward off that a extensive freedom from redness exists and that one Freedom from skin damage like cutting, scraping and burns, irritation, inflammation and allergies, as well as that neither cracked nor dried out. Furthermore, it is healthy Skin by doing that a depot function for Fat, water and blood and plays an important role in the metabolism. Is the skin unable to o. G. To take over functions or shows it obvious damage or goes from the Skin itch, so it is no longer considered healthy. skin healing in the context of the present invention, now is all that what the Skin helps in its original State to return. It is also the skin - healing, what the self - regulatory powers of Skin stimulates, trains, supports and promotes, so that these is able to fulfill its functions by being in the natural one Equilibrium state returns. Furthermore, we understand the term skin healing in context this invention all influences, that lead to, that obvious Skin diseases such as eczema, rashes, redness, Itching, swelling, blisters, oozing, Crusts in various forms at least alleviated Be cured, if not healed.

Under The term skin protection, on the other hand, means everything that to maintain the ordinary Performance of the skin in terms of their functions under specific Stressful situations is required and their own protection mechanisms goes. This concept also differs significantly from the skin care, because the skin care achieves only a cosmetic Benefits regarding sensory needs As the softness or shine under normal conditions. The skin protection but supports the Skin with additional For example, the skin's remedies, even under adverse conditions help her diverse To fulfill functions. Such adverse conditions can z. B. friction, cold, Heat, UV radiation, aggressive environmental fluids, contact with skin irritants Be materials. In a preferred embodiment, at least one the skin-healing agent contained in the coated core-shell aggregates and / or skin protecting Active substances have antiseptic activity or contain at least one antiseptic agent Substance, wherein it is preferably in the antiseptic agent an oil, especially essential oil is.

in the Context of this invention is under the attribute of antiseptic Effectiveness means an effect that enhances the self-regulatory powers of human beings Skin is useful. This efficacy is not in their expression with that of classic germicides or germicidal agents such. As phenols, halogens, alcohols with which you z. B. skin u. Mucous wounds or even medical Instruments treated to achieve asepsis (germ-free) to compare.

The Includes classic antiseptic antimicrobial measures at the place of departure or at the entrance gate of a possible Infection or at the site of infection on the body surface.

However, such strong effectiveness is not sought in the context of the invention, since they are two would lead to the elimination of harmful germs or the like, but it would also affect the natural skin flora of humans.

The particular advantage of the antiseptic active ingredients, the invention can be used are, results from a synergistic interaction of these Substances with the general functional mechanisms of human Skin, as these mild antiseptic substances such. Germs, including harmful ones Reduce germs, but not completely, that is to the extent of sterility, destroy. So there are enough germs on the skin that are enough about the self-regulatory powers to train and thereby strengthen human skin. By the interaction of the self-regulating forces of the skin with the antiseptic capital The active substances contained in the medium become the general functional mechanisms supports the skin. This is just in terms of already irritated and / or otherwise damaged Skin of great Advantage. For already irritated and / or sensitized and / or otherwise as damaged or even particularly sensitive skin are the self - regulatory powers of the Skin partially unable, albeit temporarily, to ensure skin health on its own. In synergistic, temporarily, to ensure skin health on its own. In the synergistic Cooperation with the agents according to the invention and their use according to the invention These self-regulatory powers are supported, trained and strengthened. On supported this way the detergent according to the invention or the laundry treated with it The natural Skin flora of humans.

Around The natural Does not affect the human skin flora, it is beneficial to exclude (as far as possible) such substances, which are highly disinfecting or antiseptic are effective, such. As glutaraldehyde, but at the same time a high allergen potential and irritate the skin and mucous membranes are.

unexpectedly are coated core-shell aggregates of such an embodiment especially useful for its purpose when the antiseptic effective Fabric an oil, preferably an essential oil is.

at this antiseptic effective oil it is preferably ethereal oil, which is especially selected from the group of Angelica Fine - Angelica archangelica, Anise - Pimpinella Anisum, Benzoin siam - Styrax tokinensis, Cabreuva - Myrocarpus fastigiatus, Cajeput - Melaleuca leucadendron, Cistus - Cistrus ladaniferus, Copaiba balm - Copaifera reticulata, costus root - Saussurea discolor, Edeltannennadel - Abies alba, Elemi - Canarium luzonicum, fennel - foeniculum dulce spruce needle - Picea Abies, Geranium - Pelargonium graveolens, Ho leaves - Cinnamonum camphora, immortelle (straw flower) Helichrysum ang., ginger extra - zingiber off., St. John's Wort - Hypericum perforatum, jojoba, chamomile german - Matricaria recutita, chamomile blue fine - Matricaria chamomilla, chamomile rom. - Anthemis nobilis, chamomile wild - Ormensis multicaulis, carrot - Daucus carota, mountain pine - Pinus mugho, lavandin - lavender hybrida, Litsea Cubeba - (May Chang), Manuka - Leptospermum scoparium, melissa - Melissa officinalis, sea pine - Pinus pinaster "Myrrh - Commiphora molmol, myrtle - myrtus communis, Neem - Azadirachta, Niaouli - (MQV) Melaleuca quin. viridiflora, Palmarosa - Cymbopogom martini, patchouli - pogostemon Patschuli, Peruvian Balsam - Myroxylon balsamum var. pereirae, Raventsara aromatica, rosewood - Aniba pink odora, sage - Salvia officinalis Horsetail - Equisetaceae, Yarrow extra - Achille millefolia, ribwort plantain - Plantago lanceolata, Styrax - Liquidambar orientalis, Tagetes (Marigold) Tagetes patu-la, Tea Tree - Melaleuca alternifolia, Tolu Balsam - Myroxylon Balsamum L., Virginia Cedar - Juniperus virginiana, frankincense (Olibanum) - Boswellia carteri, silver fir - Abies alba.

One Another advantage of the aforementioned essential oils lies in their particular multifunctionality, in addition to the described mild antiseptic activity from a variety of other desirable give organoleptic properties attributable to these oils are. It is these oils in most cases an expectorant Assessed effect, as they affect the mucous membranes of the respiratory system to exert a mild, positive stimulus. Furthermore, a desirable Set warmth. Deodorizing, analgesic, circulation-promoting, soothing effects could be observed in connection with the use according to the invention of these designated oils and be recognized as particularly advantageous. Here are the organoleptic Properties of these oils usually not from the main components, but from the secondary components od. Trace components shaped, which can often go into the hundreds and sometimes synergistic interact. Another advantage associated with the oils mentioned is the harmonious fragrance and fragrance emanating from them, the in many cases in people to positive feelings leads.

In this way, for example, supports a corresponding detergent or laundry washed with this not only the natural skin flora of man, but helps the human organ to additional advantages of the type just described.

In front In this background, the tea tree oil is of great advantage for the subject invention. In addition to its considerable germicidal, antiseptic, fungicidal, antiviral, wound healing, anti-inflammatory, cicatrizing Effect, it has excellent skin tolerance and offers broad further range of applications, for example with regard to the supporting Treatment of colds or diseases of the rheumatic type, gout, muscle pain.

In a preferred embodiment this is the one contained in the coated core-shell aggregates skin-protective Active ingredients around a skin-protecting oil.

The separation of the agglomerates formed from the suspension liquid can via a any device suitable for this purpose, for example a filter device, respectively. The agglomerates can subsequently be dried.

to Production of the core-shell aggregates can, for example, also be material used identical solids of different particle size become. This is e.g. in cases interesting, where a uniform release characteristic of active ingredients the entire washing and cleaning process is desired. So is for example, it is possible a porous one Core of solids with larger particle size (to be submitted particles; Core) and a higher density Shell out To combine solids of a smaller particle size, or vice versa. The porous one Core would the decreasing surface at the resolution compensate for the agglomerate and thereby ensure that the release rate does not decrease significantly.

in the Generally, as for the cups, it is preferable if in the cases the Mehrschaligkeit the solid in an outer shell a smaller Particle size as the Having solid in the Barunterliegenden shell.

Especially for the Case of suspension agglomeration, preferably in the case that the solid to be agglomerated in the binding liquid only very slightly soluble or completely insoluble is, can the binding fluid and / or the particles to be agglomerated in the binding liquid soluble Substance can be added after drying the core-shell aggregate to real material bridges between the particles. This is natural even with a common one Agglomeration possible.

For this are e.g. organic and inorganic salts, such as sodium chloride, Potassium chloride, potassium nitrate, sodium nitrate or sodium acetate Room temperature solid organic acids, such as ascorbic acid, lactic acid, citric acid, adipic acid, sugar, e.g. Monosaccharides, such as glucose, fructose, dioder oligosaccharides, such as Sucrose or lactose or urea.

One Advantage of the method according to the invention lies in the fact that the actual agglomeration / granulation process to build the core-shell aggregate in significantly shorter Time is completed as it is usual in a conventional agglomeration / granulation. With the method according to the invention For example, you can get to in just 10-40 seconds huge Agglomerates / granules, as in a conventional granulation only after about 5 minutes accrue. This reduction of the effective Granulation time is thus also in terms of energy aspect resources. Another advantage of the method according to the invention lies in the fact that the entire agglomeration / granulation process to build the core-shell aggregate associated with a significantly reduced Granulierhilfsmittelaufkommen compared to what happens in conventional agglomeration / granulation is required.

to Bleach can preferably also oxidoreductases are used. Especially good suitable for the preparation of detergent and / or detergent granules (coated core-shell aggregates) are enzymes derived from bacterial strains or fungi such as Bacillus subtilis, Bacillus licheniformis, Streptomyceus griseus, Coprinus Cinereus and Humicola insolens as well as from their genetically modified Variants obtained enzymatic agents. Preferably Proteases of the subtilisin type and in particular proteases derived from Bacillus lentus are obtained. Here are enzyme mixtures, for example Protease and amylase or protease and lipase or lipolytic acting Enzymes or from protease, amylase and lipase or lipolytic Enzymes or protease, lipase or lipolytic enzymes, but in particular protease and / or lipase-containing mixtures or mixtures with lipolytic enzymes of particular Interest. examples for Such lipolytic enzymes are the known cutinases. Peroxidases or oxidases have in some cases as proved suitable. Suitable amylases include, in particular, alpha-amylases, Iso-amylases, pullulanases and pectinases. Also Oxireduktasen are suitable.

For the preparation according to the invention of washing and / or cleaning agent granules (coated core-shell aggregates) come in addition to the above-mentioned enzymes additionally Cellulases into consideration. Cellulases and other glycosyl hydrolases can by removing pilling and microfibrils for color maintenance and to increase contribute to the softness of the textile. As cellulases are preferably cellobiohydrolases, Endoglucanases and glucosidases, also called cellobiases, or mixtures thereof used. As different cellulase types through their CMCase and avicelase activities can distinguish adjusted by targeted mixtures of cellulases the desired activities become.

Of the Proportion of enzymes or enzyme mixtures may, soferm the coated ones Core Sxchale units not entirely are enzyme-free, which is preferred, for example, about 0.1 to 5 Wt .-%, preferably 0.5 to about 4.5 wt .-%, based on the total coated core-shell aggregate, be.

Apart from possibly phosphonates, the washing and / or cleaning agent granules (coated core-shell aggregates) which can be prepared according to the invention can also contain further enzyme stabilizers. For example, the washing and / or cleaning agent granules (coated core-shell aggregates) may contain sodium formate. It is also possible to use proteases which are stabilized with soluble calcium salts and a calcium content of preferably about 1.2% by weight, based on the enzyme. In addition to calcium salts, magnesium salts also serve as stabilizers. However, it is particularly advantageous to use boron compounds, for example boric acid, boron oxide, borax and other alkali metal borates, such as the salts of orthoboric acid (H ₃ BO ₃ ), metaboric acid (HBO ₂ ) and pyroboric acid (tetraboric acid H ₂ B ₄ O ₇ ).

The coated core-shell aggregates may also contain grayness inhibitors. Grayness inhibitors have the task of keeping the dirt detached from the fiber suspended in the liquor and thus preventing the dirt from being rebuilt. For this purpose, water-soluble colloids are usually organi shear nature, for example, the water-soluble salts of polymeric carboxylic acids, glue, gelatin, salts of ether carboxylic acids or ether sulfonic acids of starch or cellulose or salts of acidic sulfuric acid esters of cellulose or starch. Also, water-soluble polyamides containing acidic groups are suitable for this purpose. It is also possible to use soluble starch preparations and starch products other than those mentioned above, for example degraded starch, aldehyde starches, etc. Polyvinylpyrrolidone is also useful. However, preference is given to using cellulose ethers, such as carboxymethylcellulose (sodium salt), methylcellulose, hydroxyalkylcellulose and mixed ethers, such as methylhydroxyethylcellulose, methylhydroxypropylcellulose, methylcarboxymethylcellulose and mixtures thereof, and also polyvinylpyrrolidone in the coated core-shell aggregates according to the invention.

In addition to the Production of the coated core-shell aggregates also dirt-repellent Substances that reduce oil and grease scavenging from textiles positively influence (so-called soil repellents). This effect is particularly evident when a textile is dirty is, which previously several times with a detergent according to the invention, containing this oil and fat dissolving component, washed has been. To the preferred oil and fat-dissolving Counting components for example, nonionic cellulose ethers such as methyl cellulose and methylhydroxypropylcellulose with a proportion of methoxyl groups from 15 to 30% by weight and of hydroxypropoxyl groups from 1 to 15 Wt .-%, each based on the nonionic cellulose ether, and the known from the prior art polymers of phthalic acid and / or of terephthalic acid or of their derivatives, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionic and / or nonionically modified derivatives of these. These substances, the also called "whiteners", can be used for the production of the coated core-shell aggregates. Optical brighteners are organic dyes that are part of the invisible Convert UV radiation of sunlight into wavelength blue light. The emission of this blue light complements the "gap" in the textile reflected Light, so that one fabric treated with optical brightener white and white to the eye appears brighter. Since the mechanism of action of brighteners their Depending on the "fibers to be dyed", a distinction is made, for example, with respect to the fibers to be applied Brightener for Cotton, polyamide or polyester fibers. The commercial ones suitable for the production of the coated core-shell aggregates Brighteners belong essentially five Structure groups, namely the stilbene, diphenylstilbene, coumarin-quinoline, diphenylpyrazole group and the group of the combination of benzoxazole or benzimidazole with conjugated systems. An overview of common brighteners is in the relevant Technical literature easy to find. Suitable are e.g. Salts of 4,4'-bis [(4-anilino-6-morpholino-s-triazin-2-yl) amino] -stilbene-2,2'-disulfonic acid or similarly constructed compounds that replace the morpholino group a diethanolamino group, a methylamino group, an anilino group or carry a 2-methoxyethylamino group. Furthermore, brighteners of the type of substituted diphenylstyrene, e.g. the Alkali salts of 4,4'-bis (2-sulfostyryl) -diphenyl, 4,4'-bis (4-chloro-3-sulfostyryl) -diphenyl, or 4- (4-chlorostyryl) -4 '- (2-sulfostyryl). Mixtures of the aforementioned brightener can be used.

Fragrances can be added to the coated core-shell aggregates to be produced according to the invention in order to improve the aesthetic impression of the resulting granules and to provide the consumer with a sensory "typical and unmistakable" washing and / or cleaning agent in addition to the cleaning performance and the color impression. As perfume oils or fragrances, individual perfume compounds, for example the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons can be used. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate and benzylsalicylate. The ethers include, for example, benzyl ethyl ether, to the aldehydes, for example, the linear Alk anal with 8-18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, Cyclamenaldehyd, Hydroxycitronellal, Lilial and Bourgeonal, to the ketones such as the Jonone, α-isomethylionone and Methylcedrylketon, The alcohols include anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol; the hydrocarbons mainly include the terpenes such as limonene and pinene. However, mixtures of different fragrances are preferably used for the production of the coated core-shell aggregates according to the invention, which together produce an attractive fragrance. Such perfume oils may also contain natural fragrance mixtures as are available from vegetable sources, eg pine, citrus, jasmine, patchouly, rose or ylang-ylang oil. Also suitable are muscatel, sage, chamomile, clove, lemon balm, mint, cinnamon, lime, juniper, vetiver, olibanum, galbanum and labdanum, and orange blossom, neroliol, orange peel and sandalwood. In order to facilitate the disintegration of the coated core-shell aggregates which can be prepared according to the invention, for example in tablet form, it is possible to incorporate disintegration aids, so-called tablet disintegrants, in them in order to shorten the disintegration times. Among tablet disintegrants and decay accelerators are understood in the general understanding of auxiliaries, which ensure the rapid disintegration of tablets in water and for the release of the active ingredients.

These Substances that are also known as explosives because of their effect become, enlarge with water access their volume, on the one hand increasing the intrinsic volume (swelling), on the other hand also about the Release of gases can create a pressure on the tablet can disintegrate into smaller particles. Well-known Disintegration aids are, for example, carbonate / citric acid systems, although other organic acids can be used. Swelling disintegration aids are for example synthetic Polymers such as polyvinylpyrrolidone (PVP) or natural polymers or modified Natural substances such as cellulose and starch and their derivatives, alginates or casein derivatives.

Usual coated Core-shell aggregates can advantageously from 0.5 to 10% by weight, preferably from 3 to 7% by weight and in particular 4 to 6% by weight of one or more disintegration aids, each based on the detergent and / or detergent granules, contain.

As preferred disintegrating agents which are suitable for the production of the coated core-shell aggregates according to the invention, cellulose-based disintegrating agents are used in the context of the present invention. Pure cellulose has the formal gross composition (C ₆ H ₁₀ O ₅ ) _π and formally represents a β-1,4-polyacetal of cellobiose, which in turn is composed of two molecules of glucose. Suitable celluloses consist of about 500 to 5000 glucose units and therefore have average molecular weights of 50,000 to 500,000. Cellulose-based disintegrating agents which can be used in the context of the present invention are also cellulose derivatives obtainable by polymer-analogous reactions of cellulose. Such chemically modified celluloses include, for example, products of esterifications or etherifications in which hydroxy hydrogen atoms have been substituted. Celluloses in which the hydroxy groups have been replaced by functional groups which are not bonded via an oxygen atom can also be used as cellulose derivatives. The group of cellulose derivatives includes, for example, alkali metal celluloses, carboxymethyl cellulose (CMC), cellulose esters and ethers, and aminocelluloses. The cellulose derivatives mentioned are preferably not used alone as disintegrating agents based on cellulose, but used in admixture with cellulose. The content of these mixtures of cellulose derivatives is preferably below 50% by weight, particularly preferably below 20% by weight, based on the cellulose-based disintegrating agent. It is particularly preferred to use pure cellulose as a cellulose-based disintegrant for the production of the coated core-shell aggregates according to the invention which is free of cellulose derivatives. As another cellulose-based disintegrant for producing the coated core-shell aggregates of the present invention, microcrystalline cellulose can be used. This microcrystalline cellulose is obtained by partial hydrolysis of celluloses under conditions which attack and completely dissolve only the amorphous regions (about 30% of the total cellulosic mass) of the celluloses, leaving the crystalline regions (about 70%) intact ,

Around the aesthetic Impression of the present invention coated core-shell aggregates can still improve the coated core-shell aggregates are dyed with suitable dyes, wherein the brightener phase (s) preferably the total amount contains / contain dye (s). Preferred dyes whose selection the expert no difficulty prepares, have a high storage stability and insensitivity to the other ingredients the washing and / or cleaning agents and against light and none pronounced substantivity across from Textile fibers so as not to stain them.

Preferred for the production of the agents according to the invention are all colorants which can be oxidatively destroyed in the washing process and mixtures thereof with suitable blue dyes, so-called blue toners. It has proved to be advantageous to use colorants for producing the coated core-shell aggregates according to the invention, which are soluble in water or at room temperature in liquid organic substances. Suitable examples are anionic colorants, for example anionic nitrosofarbstoffe. One possible dye is, for example, naphthol green (Color Index (CI) Part 1: Acid Green 1; Part 2: 10020), which as a commercial product ^® for example as Basacid Green 970 from BASF, Ludwigshafen, is, as well as mixtures thereof with suitable. blue dyes. Further suitable colorants Pigmosol come ^® Blue 6900 (CI 74160), Pigmosol ^® Green 8730 (CI 74260), Basonyl ^® Red 545 FL (CI 45170), Sandolan® ^® rhodamine EB400 (CI 45100), Basacid® ^® Yellow 094 (CI 47005) Sicovit ^® Patentblau 85 e 131 (CI 42051), Acid Blue 183 (CAS 12217-22-0, Cl Acidblue 183), pigment Blue 15 (Cl 74160), Supranol Blue ^® GLW (CAS 12219-32-8, Cl Acidblue 221 ), Nylosan Yellow ^® N-7GL SGR (CAS 61814-57-1, Cl Acidyellow 218) and / or Sandolan Blue ^® (Cl Acid Blue 182, CAS 12219-26-0) is used.

at the choice of the colorant must be noted be that the dye not too strong affinity across from the textile surfaces and here especially opposite Synthetic fibers have.

At the same time, it should also be taken into account when choosing suitable colorants that colorants have different stabilities to the oxidation. In general, water-insoluble colorants are more stable to oxidation than water-soluble colorants. Depending on the solubility and thus also on the sensitivity to oxidation, the concentration of the colorant in the coated core-shell aggregates varies. For highly soluble dyes, for example, ^® the above-mentioned Basacid Green or the above-mentioned Sandolan Blue ^®, are typically colorant Kon-concentrations in the range of a few 10 ^-2 to 10 ^-3 wt .-%, each based on the total detergent and / or detergent granules selected. In the due to their brilliance, particularly preferred, but are less readily water-soluble pigment dyes, for example the above-mentioned Pigmosol ^® ATTO-dyes, the appropriate concentration of the colorant in detergents and / or cleaning agents, however, is typically present in some 10 ^-3 to 10 ^-4. -%, based on the total washing and / or cleaning agent.

The The following example serves to illustrate the invention and is not to be considered as a restriction.

Over- and undersize are common with sodium carbonate, sodium sulfate, TAED and foam inhibitor concentrate to a mean particle size d 50 of 9 μm with an eddy current mill milled. Core material and the milled mixture were into a batch of Lödige Given mixer. The mixture was carried out on the plowshare mixer elements at a Froude number of 6.5. With the addition of granulation fluid The fine particles were adhered to the core material. As granulation fluid is a watery 25% Sokalan solution (maleic acrylic acid Copolymer sodium salt (30:70)). The real one Agglomeration lasted only about 10 to 40 seconds. The water of the polymer solution is afterwards removed in a fluidized bed again. It then took a Screen the dried material to 0.6 to 1.4 mm (d 50 = 1.02 mm; d 90 = 1.32 mm; Shape factor = form factor = Q3 = 0.87). Upper and Unterkorn were over a mill to about 10 microns ground down and returned to the granulator. The Gutkorn got into a gentle mixer and is there with one Mixture of nonionic surfactant / brightener / perfume has been coated.

Consequently resulted in a coated core-shell aggregate.

The Coated core-shell aggregate was subsequently coated with enzyme-containing Particles (uniform particle size d 50 of about 0.9 mm) and coated percarbonate-containing particles (uniform Grain size d 50 of about 1.0 mm) to a detergent.

The advantages compared to marketable products were:
The coated core-shell aggregates can not segregate as nearly all constituents are in each grain. The coated core-shell aggregates are dust-free and abrasion-resistant. The particles are nearly spherical with correspondingly high form factors. The particle size distributions are relatively narrow. The visual appearance of a single coated core-shell aggregate as well as aggregates in the collective are excellent. The coated core-shell aggregates have excellent powder properties in terms of flowability and storage stability.
