Definitions

  • the present invention relates to a detergent wipe and a method for its production, and in particular to a highly active three-phase detergent wipe
  • the optimization of cleaning performance is characterized in particular by the possibility of extending a hygienically clean condition and improving the degree of cleaning.
  • Liquid detergents are the group of zeolites and their substitutes (e.g. layered silicates and their derivatives). These support dirt adsorption and the reduction of water hardness during use.
  • a current product trend is in the way the detergent is portioned. On the one hand, this can be done by packaging a liquid detergent in small polymer bags. However, the above-mentioned problem of the missing zeolite also remains here. Another physical modification of the detergent is to mix a detergent with a fatty alcohol so that desired shapes can be achieved. However, both product concepts describe a single-phase product that can only be differentiated by portioning.
  • the first phase of the dispersion is therefore a liquid detergent concentrate consisting of detergent substances, enzymes and, if necessary, bleach;
  • the second phase of the dispersion is a softener / builder or a substance to support dirt adsorption (eg zeolite) in a fixed modification;
  • the third phase is a substrate in solid modification at room temperature, to which the mixture of the first and second phases is applied, the substrate being able to consist, for example, of viscose, polyethylene, polypropylene or polyester.
  • the solid phase of the dispersion, ie the second phase is a functional component of the heavy-duty detergent cloth.
  • the substrate is used for statistical fixing of the dispersion and consists of a raw material that is solid at room temperature.
  • One object of the present invention is to improve the performance and, in particular, the sustainability of such a detergent wipe (up to recyclability in the sense of “cradle to cradle”) and thus to provide a detergent wipe with an optimized combination of dispersion (liquid detergent lotion with a solid component). on the one hand, and cloth quality on the other.
  • Another object of the present invention is to provide a detergent wipe that is also suitable for short wash programs. Summary of the invention
  • a method of making a three-phase heavy duty detergent wipe according to claim 1, wherein a dispersion is applied to a carrier material which is solid at room temperature comprising the following steps: (a) providing a liquid detergent lotion with exothermic saponified components or soap and a water content of 10-30% by weight; (b) adding solid additives to the liquid detergent lotion using a disperser, so that the dispersion is formed with a solids content of 1-10% by weight; wherein steps (a) and (b) take place at room temperature; characterized by the following further steps: (c) providing a carrier material from a finite needled fiber; (d) applying the dispersion to the carrier material by means of a moistening device so that the carrier material statistically fixes the dispersion; wherein steps (c) and (d) take place at room temperature.
  • a three-phase heavy-duty detergent wipe according to claim 11 comprising a carrier material which is solid at room temperature, onto which a liquid detergent lotion which contains exothermic saponified constituents or soap and a water content of 10-30% by weight has, and solid additives existing dispersion, the solids content is 1-10 wt .-%, was applied, characterized in that the carrier material consists of a finite needled fiber.
  • detergent lotion means a composition which comprises one or more biocatalysts, preferably enzymes or cell extracts, in particular enzymes which are suitable for the production of detergents or cleaning agents.
  • the detergent cloth according to the invention also includes in its composition one or more functionally intact biocatalysts, preferably enzymes or cell extracts, especially enzymes.
  • room temperature means a temperature range in which biocatalysts are not irreversibly inactivated, preferably about 5 -50 ° C., particularly preferably about 15-30 ° C.
  • % by weight means according to the invention, unless stated otherwise,% by weight (w / w).
  • the term “dispersion” according to the invention preferably means a suspension, particularly preferably a suspension with a liquid phase as a continuous phase.
  • exothermic saponified constituents means according to the invention exothermic saponified or neutralized parts of the molecule, preferably exothermic saponified or neutralized fatty acid residues.
  • the term “average particle size” according to the invention means the average particle size D50 based on the arithmetic mean and can be e.g. using a "MastersizerTM2000S” laser diffractometer from Malvern Instruments Ltd., (Malvem, Worcestershire, United Kingdom), according to the manufacturer's instructions in accordance with ISO 13320: 2009 (see e.g. document ID 7.1.1.2.acl33.E from PQ Corporation ( Valleybrooke Corporate Center, Malvem, PA 19355-1740, USA)).
  • the term “diffusion” means according to the invention the speed of the transition of the suspension into the wash water of the application in the sense of an accelerated increase in concentration in the wash water in comparison with the prior art of the detergent cloth.
  • the term “sustainability” is sometimes controversially discussed in science, so that it makes sense to define this aspect depending on the area of application by means of certain sustainability features.
  • the central sustainability characteristics result from (i) the conservation of resources, (ii) the duration of the washing program (short washing programs), (iii) the proportion of plastics (microplastics), (iv) the distribution (C0 2 balance), (v ) the application by the consumer (dosage), (vi) the energy balance in production, and (vii) the possibility and extent of reusability (recycling).
  • the aim of the present invention with regard to sustainability can therefore be derived from the sustainability features described below.
  • the present dosage forms of the detergent can be divided into the groups of powders, liquid detergents and ready-to-use detergents (such as detergent cardboard and polymer bags filled with liquid detergent).
  • the composition of powders is characterized, among other things, by the fact that a portion of the recipe consists of sodium sulfate or the like. There are substances that are used to increase the pourability of the powder - these materials have no function in terms of washing activity.
  • Liquid detergents on the other hand, use a not inconsiderable proportion of water, which is due to the viscosity, flowability and thus simple dosage to be achieved.
  • the finished dosing detergents in the form of polymer bags filled with liquid detergents usually have a high proportion of water or solubilizers (e.g.
  • the task of conserving resources should be to develop a detergent that has the highest possible degree of wash-active components and contains no or only a small proportion of additives such as those listed in Tab. 1, because fillers, flow agents or molding materials are not for them anyway Core washing requirement required.
  • FIG. 1 The suitability of various detergent forms for short-washing programs, which is dependent on the diffusion of the washing-active substances, is shown in FIG. 1 as the activity applied over time.
  • Powder and liquid detergents are usually transferred to the washing chamber or drum via the detergent dispenser using water. There they become quickly active and are therefore suitable for a short wash program.
  • the gel pillows are placed directly in the washing drum (as part of the addition of textiles) and are only after the Process of dissolving the outer jacket material (usually polyvinyl alcohol) by washing water. This explains the delay in activation during the washing process.
  • the detergent cloth is also placed directly in the detergent drum and releases washing-active substances when the washing water is flushed into the washing drum using a diffusion process. Since the concentration of the wash-active substances within the cloth decreases over time, the wash-active performance also decreases with the duration of the washing process. For the suitability of ready-to-use detergents in short-washing programs, however, rapid diffusion of the detergent components (in the case of the detergent suspension according to the invention) is required.
  • microplastics are used in all detergent products with a liquid main phase, which serve among other things for stabilization (single-phase product). The same applies to the polymer bags / gel pillows. It should be noted that these proportions were not shown in Table 1 above, since they are polymer components required for the product and should not be considered as fillers in terms of the nature of the product.
  • detergent wipe which is also described below in terms of sustainability, is the first detergent product that is free of polymers and therefore contains neither primary nor secondary microplastics.
  • the C0 2 balance which is dependent on the technical parameters of the respective detergent, is based on the consideration of the physical quantities of the volume and the mass.
  • the detergent volumes for an average wash cycle (detergent load) using conventional detergents are shown in Table 2.
  • the volume per detergent cycle should be kept as low as possible.
  • Detergent concentrates have already been introduced in the development of detergents. However, these were not accepted on the part of the consumers, since the frequent overdosing caused the price per wash load to be significantly higher. This also means that the user obviously adopts learned behavior patterns. On average, an overdose of approx. 7% can be assumed for detergent powders and liquid detergents. In this regard, the application forms of the ready-to-use detergents represent an advantage, since the pollution of water and the environment due to incorrect dosing can be largely avoided.
  • the second way of producing detergent powders is by using an extruder in which the premixing of a paste takes place at 80-110 ° C, whereupon cut cylinders are formed into spheres in a rounder at likewise 80-110 ° C, whereupon as in the first
  • the process again involves adding temperature-sensitive components. This second procedure is shown in Table 4.
  • the wash-active components of a detergent are used during the application, ie during washing (dirt solution, dirt transport, water softening, bleaching of stains, etc.). Therefore, the previous ecological detergents have a pronounced proportion of biodegradable components (with the aim of, for example, meeting the requirements of the "Blue Angel").
  • Components that are biodegradable are also called “cradle to cradle” components in the detergent industry because they are converted into their origin (C0 2 and water) by nature.
  • a recovery of the components used in the known detergent products has so far been possible only to a certain extent. For example, the above-mentioned fillers and also other non-detergent components cannot be recovered, as can be seen in Table 5.
  • the objective of the present invention mentioned at the outset arose as the development of a finished dosage detergent which was improved with regard to its performance on the one hand and its sustainability on the other.
  • the detergent cloth according to the invention comprises a carrier material which consists of a finite fiber in order to increase the diffusion exit points along the capillary cross section.
  • a mechanically needled material consisting of a pure plastic recyclate with hydrophobic properties was used. Due to the increase in diffusion achieved (in the sense of a faster diffusion of the wash-active components into the wash water), the detergent cloth according to the invention is particularly suitable for short-wash programs.
  • the detergent cloth according to the invention is distinguished on the one hand by the first combination of biodegradable detergent-active substances with a carrier material, on the other hand, which can be completely recycled (closed recycling cycle of the non-detergent carrier material).
  • a dispersion - which is characterized by the biodegradability of the raw materials and their low KVV t X value (the ingredients of the dispersion are specified further below) - is applied to the Carrier material described above applied at room temperature, which consists of a 100% recyclable finite fiber and allows the lotion to diffuse more quickly during washing.
  • the production comprises the following steps:
  • steps (c) applying the dispersion to the carrier material, consisting of a 100% recyclable finite fiber, by means of a moistening device, so that the diffusion-strong carrier material statistically fixes the dispersion; wherein steps (a) - (c) take place at room temperature.

From the dry carrier material (2.44 g - 5.49 g, consisting of a recycled monopolymer in the form of finite needled fibers) samples were cut out and washed with 50 mL dist. Water added. Microscopy was carried out using squeeze specimens (Jenamed-II up to 600x magnification and Nageotte counting chamber).
