Definitions
- the present invention relates to a scatterable agent based on cellulose with an active oxygen source for dry cleaning textiles, in particular carpets.
- adsorbents for cleaning carpets and other textile coverings on the spot, in addition to liquid cleaning agents such as shampoos, powdery cleaning agents are especially used, which are particularly convenient for laypersons.
- Such cleaning powders consist essentially of larger amounts of adsorbents and a cleaning liquid adsorbed thereon, which mostly consists mostly of water.
- the cleaning liquid is assumed to provide for the detachment of the dirt particles from the fibers and for their transport to the adsorbent, which is then brushed and / or suctioned off after drying with the dirt.
- adsorbents A wide variety of materials have been proposed as adsorbents. Cellulose powders such as are described, for example, in European patent application EP 0 178 566 have recently gained particular importance.
- peroxide-containing bleaching agents for example hydrogen peroxide
- peroxide-containing bleaching agents for example hydrogen peroxide
- aqueous bleach-containing solutions for the extensive cleaning of carpets (L. Carlhoff, H. Krüssmann Manualr Desir Desirmürber-Kalender, publisher G. Dierkes, Frankfurt aM 1989, 215-224).
- high bleach concentrations and long exposure times must be used to adequately remove the stains, which are also associated with a strong odor nuisance when using peracetic acid, so that this method has not become established in practice.
- Bleach-containing dry cleaning agents for carpets are disclosed in Japanese Patents JP 044 974, JP 066654 and JP 251 247. However, the agents described there are not based on cellulose powder as a carrier material.
- carpet cleaners are known from the British patent specification GB 65/36749 which, based on the composition, contain 18 to 35% by weight wood flour, 0.2 to 1% by weight peroxidic bleaching agents, for example hydrogen peroxide, 25 to 70% by weight.
- Water 10 to 40% by weight of volatile low-boiling solvents in the form of petroleum fractions or chlorinated hydrocarbons, 0.25 to 2% by weight of organic emulsifier in the form of nonionic or non-soapy anionic organic synthetic detergents and 0.25 to 1% by weight selected Contain alkali metal detergent salts.
- Wood and also wood flour which is very finely chopped wood, consists of about 40 to 50% cellulose, 25 to 30% lignin and 15 to 30% polyoses as well as a few percent of other ingredients, e.g. resins, waxes, terpenes and Terpenoids or tannins such as tannin so that the agents described contain cellulose in amounts of less than 20% by weight.
- wood flour-based cleaners are unsuitable due to a number of disadvantageous properties - low cleaning performance, low adsorption capacity, easy clumping, discoloration due to tannins, resins, etc.
- the bleach in these carpet cleaners is only used to bleach the wood flour and not to remove oxidizable stains from the textile material to be cleaned.
- straight Beech wood flour undesirable due to its toxicological properties, however
- Beech wood cellulose is a suitable carrier material for common cellulose-based cleaning powder.
- the object of the present invention was to provide a powdered carpet cleaner based on cellulose, which provides very good cleaning performance both on surfaces and on colored stains, without damaging the carpet, in particular its coloring, and for a longer period without noticeable impairment of cleaning performance remains stable.
- the subject of the present application is therefore a scatterable dry carpet cleaning agent containing cellulose powder and an active oxygen source, characterized in that it is free from wood flour.
- the carpet cleaning powders according to the invention are characterized, by means of the active oxygen source contained, by an unexpectedly significantly improved cleaning performance compared to conventional cellulose-based carpet cleaning powders.
- stubborn colored stains for example from coffee, red wine or fruit juices such as blueberry juice, can largely, mostly even completely, be removed from the carpet without the carpet being damaged by the agents according to the invention.
- carpet cleaners according to the invention are their surprisingly high storage stability. Without being limited to certain mechanisms, the adsorption of the peroxidic compound on the cellulose could be the reason. After storage for several weeks or months, the cleaner is fully efficient.
- the cleaning agent can be packaged in airtight plastic or metal-based films without creating undesirable pressure in the packaging.
- Preservatives of any kind are dispensed with.
- the cellulose powders suitable for the agents according to the invention are produced from commercially available cellulose, which is generally obtained from parts of plants, in particular from wood, by comminution with the aid of mechanical and / or chemical processes. Such powders, which are colorless and almost free of lignin and other impurities originating from the plant material, are commercially available in various finenesses.
- the finer qualities which have an average fiber length in the range from 50 to 400 micrometers, are preferably suitable.
- the average fiber thickness for these qualities is usually between 10 and 50 micrometers.
- the particle size of the cellulose powder can also be determined using a sieving method, for example using air jet sieving in accordance with DIN 53734. Cellulose powder which has the following particle size distribution (according to the aforementioned method) is therefore also preferred:
- a particularly preferred cellulose type is beech wood cellulose.
- the proportion of cellulose powder in the agent according to the invention is preferably 30 to 60% by weight, in particular 35 to 55% by weight, most preferably 40 to 50% by weight, based on the finished agent.
- the agents according to the invention can also be powdered
- Adsorbents as they are known per se for such dry cleaning agents, if this is desirable in order to achieve special additional effects. Examples of such
- Adsorbents are colloidal silicon dioxide, bentonite, diatomaceous earth, zeolite, starch and
- Plastic foam powder such as ground polyurethane foam.
- Adsorbent which also acts as a volume generator, has ground foam glass
- Perlite (Perlite) proven.
- the amount of these additional adsorbents is chosen in any case so that the properties of the agents are not adversely affected.
- Their content in the agents according to the invention is therefore always below the content of cellulose powder, preferably it is less than 50% by weight, in particular less than 30% by weight, based on the content of cellulose powder.
- the agents according to the invention contain one or more active oxygen sources, preferably hydrogen peroxide, as the essential active ingredient.
- active oxygen sources include compounds releasing hydrogen peroxide in aqueous solution, for example percarbonates, perborates and metal peroxides, and also other types of peroxides, such as dialkyl peroxides, diacyl peroxides, preformed percarboxylic acids, persulfates, organic and inorganic peroxides or hydroperoxides.
- dialkyl peroxides diacyl peroxides
- preformed percarboxylic acids persulfates
- organic and inorganic peroxides or hydroperoxides are also suitable.
- alkyl and aryl silicon peroxides known, for example, from German patent applications DE 195 38 629 AI and DE 195 40 581 AI, as well as the silicon peroxide also described there.
- acylating agents can be contained as peroxide activators, which form salts of organic percarboxylic acids
- the preferably contained hydrogen peroxide sources are alkaline, solid inorganic peroxides, for example perborate tetrahydrate, perborate monohydrate and percarbonate, of which in turn perborate monohydrate is particularly preferred.
- Suitable organic and inorganic peroxides or hydroperoxides in the sense of the teaching according to the invention include diacyl and dialkyl peroxides or hydroperoxides such as Dibenzoyl peroxide, tert-butyl hydroperoxide, dilauroyl peroxide, dicumyl peroxide and persulfuric acid or their salts and mixtures of the compounds mentioned.
- Pre-formed peracids suitable according to the invention are, for example, diperoxydodecanedioic acid (DPDDA), magnesium perphthalic acid, perlauryl acid, perbenzoic acid, diperazelaic acid and their salts, and also mixtures of these compounds.
- DPDDA diperoxydodecanedioic acid
- magnesium perphthalic acid perlauryl acid
- perbenzoic acid diperazelaic acid and their salts, and also mixtures of these compounds.
- the content of active oxygen source is usually in amounts, based on the composition, of up to 15% by weight, preferably up to 10% by weight, in particular up to 5% by weight, extremely preferably up to 2% by weight .
- the content of active oxygen source is to be understood as meaning the amount of hydrogen peroxide which is stoichiometrically equivalent to the respective peroxide compound, so that, for example in the case of sodium perborate tetrahydrate, “NaBO 3 -4H O” contains a content of 1% by weight, based on the composition, of active oxygen source
- the amount of active oxygen can be titrated oxidimetrically with permanganate, iodide or cerium (IV) sulfate in aqueous acidic solution.
- the activators used according to the invention are compounds which are capable of acylating hydrogen peroxide in an alkaline aqueous solution. Such activators have been developed in large numbers for textile washing. The majority of the cases are reactive amides or esters or anhydrides which are able to transfer an acyl group to hydrogen peroxide. A list of such activators can be found, for example, in DE-A 3832 589 on page 7.
- N, N, N ', N'-tetraacetylethylene diamine (TAED), 1,5-diacetyl-2,4-dioxohexahydro-1 are used , 3,5-triazine (DADHT) and pentaacetylglucose (PAG) individually or in mixtures are preferred.
- the amount of activator that is used to prepare the cleaning solution is generally chosen so that 0.02 to 1 mol, preferably 0.05 to 0.5 mol, of reactive acyl groups from the peroxide for activating 1 mol of active oxygen from the peroxide Activator are available. It is therefore usually between 0.01 to 5 g, in particular 0.02 to 1.5 g, per 100 g of the solution.
- the activator is to be packaged in solid form together with the peroxide and optionally other active ingredients of the cleaning solution, it may be expedient and advantageous to prevent the activator from reacting prematurely with the peroxide or other ingredients of the agent in a manner known per se by wrapping or
- the cleaning solution adsorbed on the cellulose carrier contains, among other things, one or more of the aforementioned active oxygen sources. In the simplest case, it is an aqueous hydrogen peroxide solution.
- the amount of this impregnating liquid is measured so that it still depends on the solid components of the agent, i.e. in particular of cellulose powder, is absorbed and the spreadability of the agents is guaranteed.
- the water content which results from the amount of water added during production and the water already contained in the raw materials, is preferably 35 to 70% by weight, in particular 40 to 60% by weight.
- the impregnating liquid can, if this appears appropriate for special reasons, also contain further auxiliaries and additives which are advantageous, for example, for increasing the cleaning effect, improving the re-soiling behavior or preserving the finished agent.
- the liquid preferably contains one or more suitable complexing agents.
- suitable complexing agents in the context of the invention include phosphonic acids and their salts, aminocarboxylic acids and their salts and also multi-functionalized aromatic chelating agents.

- the complexing agents are preferably present in amounts, based on the composition of the agents, of up to 2% by weight, in particular up to 1% by weight, most preferably up to 0.4% by weight.
- Surfactants can also be present as cleaning-active additives, these surfactants preferably originating from the classes of anionic and nonionic surfactants. While excellent surface cleaning can be achieved without the addition of surfactants, the addition of surfactants can further improve the removal of greasy stains.
- a surfactant addition of up to 10% by weight is sufficient; the compositions preferably contain 0.05 to 5% by weight, in particular 0.1 to 2% by weight, based on the total weight of the composition, of surfactants. From the large number of known surfactants, those substances are particularly suitable which, together with the adsorbents contained and possibly other nonvolatile constituents of the compositions, dry to a solid, brittle residue.
- Suitable nonionic surfactants for the agents according to the invention are, in particular, addition products of 1 to 30, preferably 4 to 15, moles of ethylene oxide or mixtures of ethylene oxide and propylene oxide with one mole of a compound having 10 to 20 carbon atoms from the group of alcohols, alkylphenols, carboxylic acids and carboxamides.
- the condensation products from reducing sugars and long-chain alcohols known under the name alkyl glycosides are also very suitable.
- the addition products of ethylene oxide with long-chain primary or secondary alcohols such as e.g. Fatty alcohols or oxo alcohols and the alkyl polyglucosides made up of glucose and fatty alcohols with 1 to 3 glucose units per molecule and 8 to 18 carbon atoms in the alkyl radical.
- Suitable anionic surfactants are in particular those of the sulfate or sulfonate type, but other types such as soaps, long-chain N-acyl sarcosinates, salts of long-chain sulfosuccinic acid esters or salts of ether carboxylic acids, such as those obtained from long-chain alkyl or alkylphenyl polyglycol ethers and chloroacetic acid are available.
- the anionic surfactants are preferably used in the form of the sodium salts, but the lithium salts can also offer advantages.
- Particularly suitable surfactants of the sulfate type are the sulfuric acid monoesters of long-chain primary alcohols of natural and synthetic origin with 10 to 20 carbon atoms, ie of fatty alcohols, such as, for example, coconut fatty alcohols, tallow fatty alcohols, oleyl alcohol or the C 0 -C 20 oxo alcohols and those of secondary alcohols thereof Chain lengths.
- the sulfuric acid monoesters of the aliphatic primary alcohols, secondary alcohols or alkylphenols ethoxylated with 1 to 6 mol of ethylene oxide come into consideration.
- These surfactants are also known as ether sulfates. Sulfated fatty acid alkanolamides and sulfated fatty acid monoglycerides are also suitable.
- the surfactants of the sulfonate type are primarily sulfosuccinic acid monoesters and diesters with 6 to 22 carbon atoms in the alcohol parts, the alkylbenzenesulfonates with C 9 -Ci 5 -alkyl groups and the esters of ⁇ -sulfofatty acids, for example the ⁇ -sulfonated methyl or ethyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.
- alkanesulfonates which are obtainable from C 2 -C 8 -alkanes by sulfochlorination or sulfoxidation and subsequent hydrolysis or neutralization or by bisulfide addition to olefins, and also the olefin sulfonates, which are mixtures of alkene and hydroxyalkanesulfonates and Disulfonates as obtained, for example, from long-chain monoolefins with a terminal or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products.
- Particularly preferred surfactants are the olefin sulfonates, which are preferably used in amounts of 0.1 to 1% by weight in the recipes, but in particular the fatty alcohol sulfates and fatty alcohol ether sulfates, which are preferably used in amounts between 0.1 and 2% by weight .
- the agents according to the invention can furthermore contain organic solvents. Suitable organic solvents are both water-miscible and water-immiscible solvents, provided that they do not attack the textiles and are sufficiently volatile to evaporate in the desired time after the agents have been applied to the textiles. When selecting the solvents, it is also important to ensure that they have sufficiently high flash points in the finished product mixture and are toxicologically harmless.
- Alcohols, ketones, glycol ethers and hydrocarbons, for example isopropanol, acetone, ethers of mono- and diethylene glycol and mono-, di- and tripropylene glycol with boiling points between 120 ° C and gasolines with a boiling range of 130 to 200 ° C, as well as mixtures, are particularly suitable from these solvents.
- Monoalcohols with 2 to 3 carbon atoms and mixtures thereof are preferably used.
- the proportion of organic solvents is usually not more than 20% by weight, preferably up to 10% by weight, in particular up to 5% by weight, based on the total cleaning agent.
- the pH of the compositions is preferably in the range from 6 to 10, in particular from 7 to 9.5, most preferably from 7.5 to 9, and is adjusted by adding acid and / or alkali, preferably sodium hydroxide solution.
- the agents of this invention can also contain small amounts of other auxiliaries and additives customary in textile and carpet cleaning agents.
- active ingredients are antistatic components, optical brighteners, substances that reduce re-soiling, such as drying, embrittling water-soluble or water-dispersible polymers, for example polyacrylates, additives that improve spreadability and spreadability, preservatives and perfume.
- antistatic components such as drying, embrittling water-soluble or water-dispersible polymers, for example polyacrylates
- additives that improve spreadability and spreadability preservatives and perfume.
- waxes or oils bind dust.
- no more than 5% by weight of these auxiliaries and additives are used; the content is preferably not more than 2% by weight, based on the total composition.
- Particles can be regularly or irregularly shaped bodies.
- Carpet cleaning agent can roll under the brush passed over the carpet.
- Shapes are thus spheres, cylinders, ellipsoids, egg shapes, but also irregularly shaped bodies, such as those caused by the agglomeration of smaller particles
- Granules arise, in question. Especially with very elastic and easily deformable
- materials can also have a more angular shape, including cubes and cuboids, and can be suitable for the agents according to the invention.
- the rollable particles can consist of various materials. Rollable particles which consist predominantly to completely of viscose, natural sponge or open-pore plastic foam are particularly preferred. To produce the rollable particles, it is preferable to start with larger pieces of material which are cut to the desired size by cutting or grinding. Foamed material, nonwoven fabric or fabric is preferably used as the starting material. In a particularly preferred embodiment, the rollable particles consist of viscose sponge flakes.
- the rollable particles combine with fluff and fibers that have deposited on the carpets and can then be easily removed from the carpet surface together with them.
- the content of rollable particles in the agents according to the invention can be relatively small, since only a few particles are sufficient to achieve the desired effect.
- the proportion of rollable particles in the compositions is preferably up to 10% by weight, in particular up to 4% by weight, most preferably up to 1% by weight, based on the total composition.
- the preparation of the agents presents no problems, so that technically simple, mostly one-step processes can be used.
- simple mixing equipment such as Paddle or drum mixers are used, in which cellulose powder and, if appropriate, further solid components are introduced and then sprayed with the liquids, which may contain other constituents in solution, while moving.
- the agents can be produced in this way in very finely divided or more or less agglomerated form, but the composition always ensures that the agglomerated forms on the textiles easily disintegrate without great mechanical effort.
- fluffy agglomerates the free-flowing properties of the agents can be dampened, right down to products that flow with great hesitation, as are preferred for certain application purposes.
- the bulk density of the agents can also be influenced to a certain extent in the manufacturing process by choosing more or less compact agglomerates. So the agents usually have bulk weights in the range of 200 to 400 g / 1, with the result that relatively large volumes are used per unit area. This makes it easier to distribute the product evenly, especially when sprinkled on carpets by hand.
- the cleaning of the textiles and carpets takes place in such a way that the cleaning agents according to the invention are sprinkled onto the textiles manually or with the aid of a suitable scattering device and then rubbed into the textiles more or less intensively, for example with the aid of a sponge or a brush.
- training times 0.5 to 2.5 minutes, preferably 0.5 to 1.5 minutes per square meter are chosen.
- the textiles are allowed to dry until the cleaning agents that combine with the dirt have turned into dry residues. These residues are then removed from the textiles mechanically, for example by brushing or vacuuming.
- Cellulose powder and optionally viscose flakes were placed in a paddle mixer and premixed.
- the aqueous cleaning liquid was prepared separately from the other components in a mixing container. This liquid was then sprayed onto the adsorbent with further agitation of the paddle mixer. Slightly moist, but free-flowing products were created.
- the type Arbocel ® B 800 X from J /? S Rettenmaier & Söhne was used as the cellulose powder, which according to the manufacturer has an average fiber length of 200 ⁇ m and an average fiber thickness of 20 ⁇ m and the following sieving parameters for air jet sieving:
- the viscose flakes used were a product from Beli-Chemie GmbH and are offered for use as suction flakes to absorb spilled liquids.
- the material has a bulk density of about 90 g / 1.
- the area cleaning performance was checked on pieces of carpet that were provided with artificial soiling.
- the working method is largely an established standard.
- a light beige polyamide velor carpet and a light beige virgin wool loop carpet were used as carpet materials, which in pieces measuring 30 cm x 60 cm in a laboratory soiling device with 10 g of test soiling, consisting of 85% by weight of the sieved contents of a vacuum cleaner bag and 15% by weight from a standard mixture of kaolin, quartz powder, iron oxide and soot (available from the Krefeld laundry research institute). The carpet pieces were then vacuumed thoroughly.
- the cleaning tests were carried out on the soiled pieces of carpet in such a way that 125 gm " (polyamide carpet) or 150 gm " (new wool carpet) cleaning powder were evenly sprinkled on and then worked into the surface by brushing.
- a medium-hard brush with polypropylene bristles was used as the tool, with which the surface was worked evenly with strong, overlapping lines in the longitudinal and transverse directions for about 25 seconds.
- After drying overnight at The carpet pieces were vacuumed thoroughly at room temperature until powder residues were no longer visible on the carpet.
- the evaluation was carried out using the Minolta Chromameter CR310 color difference measuring device using the CIEL AB method for colorimetric determination of color differences (DIN 6174).
- the color distance ⁇ E aD between sample (index P) and reference (index B) is determined as a Euclidean distance in the three-dimensional color space spanned by the color measures L, a and b.
- the color space coordinates L, a and b result from the measured standard color values X, Find Z (see also DIN 5033 Part 2).
- the dimension L * also called gray value, detects the brightness, while chroma and hue are positioned in the ⁇ * / b * plane.
- the change in the color position E aD caused by the cleaning of the soot-covered carpet covered with dark soot is essentially due to the change in the brightness coordinate L to larger values in the sense of brightening, while the color coordinates a and b are not significantly shifted.
- Table 2 shows the color difference ⁇ Eab - Eat > , p - Eab.B as the cleaning result of the example formulations, ie how large the color value E a b after cleaning (E a b, p) is greater than before (E ab , ß ) was how much lighter and therefore cleaner the carpet got from cleaning the surface.
- the cleaning performance with regard to stained soiling was determined on the same textile floor coverings that were stained with hot milk coffee, red wine or blueberry juice. Powder was sprinkled on the aged stains (polyamide carpet: 100 g / m 2 ; virgin wool carpet: 200 g / m 2 ) and worked in intensively with a brush. To the powder was sucked off thoroughly after exposure overnight.
- the visual assessment of the stain removal by 5 test persons with good lighting by means of a daylight lamp and comparison with the respective uncleaned reference carpet is summarized in Table 3 for the example formulations (El, VI) and the different stains. No change in color of the carpet was observed.
- the exemplary agent El was tested for its hydrogen peroxide content by means of permanganatometric titration after storage over a period of 9 months. The determined loss of hydrogen peroxide was only 0.06% by weight.
- the examples demonstrate the superior cleaning performance of the cellulose-based carpet cleaning powder (EI) containing hydrogen peroxide according to the invention compared to the conventional cellulose-based cleaner without bleach (VI) and the high storage stability.
