Definitions

  • the present invention relates to a wet wipe with a carrier material that consists of biodegradable materials and a method for its production.
  • the present invention relates to a three-phase heavy-duty detergent sheet with sustainability features using a composite carrier material, and a method for its production.
  • Hygiene has been a priority since the dawn of civilization. After all, hygiene is an important component in people's everyday lives. People's idea of hygiene is primarily about maintaining health. With the further development of the possibilities, in addition to the basic cleaning effects, the scent and the improvement of the cleaning performance through the raw material mixtures used came into focus. The optimization of the cleaning performance is characterized in particular by the possibility of extending a hygienically clean state and improving the degree of cleaning.
  • liquid detergents have not yet reached the cleaning level of heavy-duty detergents (i.e. a mixture of solids).
  • the reason for this lies in the fact that a liquid detergent is limited to liquid components or components that are readily soluble in water.
  • the decisive missing substance in a liquid detergent is the group of zeolites and their substitutes (e.g. phyllosilicates and their derivatives). These support dirt adsorption and the reduction of water hardness during use.
  • a current product trend is 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 blending 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 the portioning.
  • a two-phase product is described in DE 10 2010 060 126 A1.
  • the detergent cloth disclosed there is characterized by the combination of a carrier material with a liquid impregnation solution (two-phase product).
  • the disadvantage of the missing zeolite still remains here.
  • the applicant's DE 102013 014015 A1 discloses a decisive further development in the form of a three-phase heavy-duty detergent cloth which consists of a dispersion (ie a liquid continuous phase with solid components) and a solid substrate.
  • the dispersion is applied to a carrier material that is solid at room temperature.
  • the carrier material can be either a fleece or a fatty alcohol or a substrate for phase combination of a dispersion with another separate phase.
  • the first phase of the dispersion is therefore a liquid detergent concentrate consisting of washing-active substances, enzymes;
  • the second phase of the dispersion is a softener/builder or a substance to support dirt adsorption (eg zeolite) in a solid modification;
  • the third phase is a substrate which is present in a solid modification at room temperature and to which the mixture of the first and second phases is applied, the substrate being able to consist of, for example, viscose, polyethylene, polypropylene or polyester.
  • the solid phase of the dispersion, ie the second phase represents a functional component of the heavy-duty detergent cloth.
  • the substrate serves to randomly fix the dispersion and consists of a raw material that is solid at room temperature.
  • the applicant's DE 102014 012 380 A1 takes a different approach to production, in that a liquid lotion is not applied to a solid carrier material but rather a liquid lotion to a carrier material pretreated with solids such as zeolites, which has the advantage that larger particles are used that they are distributed over the entire depth of the substrate and that the functional solids incorporated in the substrate have a depot function, with the effect that the diffusion of the particles during the washing process takes longer, so that they are available over a longer period of time.
  • DE 10 2014 008 586 A1 discloses a further development of the three-phase detergent cloth to the effect that encapsulated bleach can now also be used together with the enzymes without the bleach deactivating the enzymes.
  • DE 10 2015 014 015 A1 discloses the further development of the detergent cloth with regard to ecological aspects using a carrier material made of recycled material.
  • a wet wipe according to claim 1 comprising a carrier material which is solid at room temperature and to which a liquid cleansing lotion has been applied or onto which a dispersion consisting of a liquid cleaning lotion and solid additives has been applied or into which solid additives have first been introduced and to which a liquid cleaning lotion has then been applied, characterized in that the carrier material is a biodegradable composite carrier material which consists of a mixture of at least two biodegradable fibers.
  • a detergent sheet this results in particular in a three-phase heavy-duty detergent sheet according to claim 7, comprising a carrier material that is solid at room temperature, to which a dispersion consisting of a liquid detergent lotion and solid detergent additives has been applied or into which solid detergent additives have first been introduced and which has then been applied with a liquid detergent lotion, characterized in that the substrate is a biodegradable composite substrate consisting of a mixture of at least two biodegradable fibers.
  • the object has further been achieved by a method for manufacturing a wet wipe according to claim 13, characterized by the following steps: (i) blending at least two biodegradable fibers; (ii) needling and/or thermally pressing the fibers to form a biodegradable room temperature solid composite support; (iii) Applying a liquid cleansing lotion to the biodegradable composite support, or applying a dispersion consisting of a liquid cleansing lotion and solid additives to the biodegradable composite support, or introducing solid additives into the biodegradable composite support, followed by applying a liquid cleansing lotion to the already solid Biodegradable composite carrier provided with additives.
  • a method for producing a three-phase heavy-duty detergent sheet characterized by the following steps: (i) mixing at least two biodegradable fibers; (ii) needling and/or thermally pressing the fibers to form a biodegradable solid composite support at room temperature; (iii) Applying a dispersion consisting of a liquid detergent lotion and solid detergent additives to the biodegradable composite support or introducing solid detergent additives into the biodegradable composite support, followed by applying a liquid cleaning lotion to the biodegradable composite support already provided with solid detergent additives.
  • Advantageous refinements of the method and of the damp or three-phase heavy-duty detergent cloth result from the further dependent claims.
  • the term “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 composition of the three-phase heavy-duty detergent cloth according to the invention therefore also includes one or more functionally intact biocatalysts, preferably enzymes or cell extracts, in particular enzymes.
  • room temperature means a temperature range in which biocatalysts are not irreversibly inactivated, preferably about 5-50.degree. C., particularly preferably about 15-30.degree.
  • % or % by weight means % by weight (w/w) unless otherwise specified.
  • the term “dispersion” preferably means a suspension, particularly preferably a suspension with a liquid phase as the continuous phase.
  • exothermically saponified constituents means exothermally saponified or neutralized parts of the molecule, preferably exothermally saponified or neutralized fatty acid residues.
  • biodegradability means degradation of a material under the parameters of industrial composting (with the presence of heat, bacteria).
  • the term "average particle size” means the average particle size D50 based on the arithmetic mean and can be determined, for example, using a laser diffractometer "MastersizerTM 2000S” from Malvern Instruments Ltd., (Malvern, Worcestershire, United Kingdom), according to the manufacturer's instructions ISO 13320:2009 (see e.g. document ID 7.1.1.2.acl33.E from PQ Corporation (Valleybrooke Corporate Center, Malvern, PA 19355-1740, U.S.A.)).
  • the previous dosage forms of detergent can be divided into the groups of powder, liquid detergent and ready-to-dose detergent (such as detergent cardboard and polymer bags filled with liquid detergent).
  • powders are characterized, among other things, by the fact that part of the formulation consists of sodium sulphate or similar substances which are used to increase the pourability of the powder - these materials do not have a function in terms of washing activity.
  • Liquid detergents on the other hand, use a not inconsiderable proportion of water, which can be explained by the viscosity and flowability to be achieved, and thus simple dosing.
  • the ready-to-dose detergents in the form of polymer bags filled with liquid detergent usually have a high proportion of water or solubilizers (e.g.
  • Table 1 Average proportions of non-detergent components in % by weight
  • the task of conserving resources should be to develop a detergent that has the highest possible degree of washing-active components and contains no or only a small proportion of additives such as those listed in Table 1, because fillers, flow materials or molding materials are not for the core requirement of washing required.
  • the CCh balance which depends on the technical parameters of the respective detergent, is based on the consideration of the physical quantities of volume and mass.
  • Table 2 shows the detergent volumes for an average wash cycle (detergent load) using conventional detergents.
  • the volume per detergent cycle should be kept as low as possible.
  • Detergent concentrates were also introduced in the development of detergents. However, these were not accepted by the consumers, since the pricing per wash load was significantly higher due to the frequent overdosing. This also means that the user apparently adopts learned behavior patterns. On average, an overdose of approx. 7% in the area of powder and liquid detergents can be assumed. In this regard, the application forms of the ready-to-use detergents represent an advantage, since the pollution of water bodies and the environment through incorrect dosing can be largely avoided. Detergents - energy balance in production
  • a complete energy balance is always directly related to the starting materials used.
  • a distinction can be made between hot processes and cold processes.
  • it is advisable to use a cold process in the detergent production stage. This is largely the case only in the production of pure liquid detergents, which, however, have a significantly weaker cleaning performance due to the initially mentioned absence of zeolites, for example, since the incorporation of solid components is not possible.
  • Detergent powder and detergent cardboard which opens up the possibility of incorporating solid components, and the polymer bags filled with liquid detergent are produced in a hot process. This means that all currently known detergents that have a solid that increases the washing performance, such as zeolite, have to be produced using a hot process.
  • Detergent powders according to the prior art can be produced in two ways. Either a high-pressure spraying process is used, in which a previously mixed slurry of temperature-resistant components of a detergent is dried using a spray tower in a hot countercurrent at 110 - 130 °C, after which temperature-sensitive components are added. This procedure is shown in Table 3.
  • the second way of producing detergent powders is using an extruder, in which a paste is premixed at 80 - 110 °C, after which cut cylinders are formed into balls in a rounder also at 80 - 110 °C, after which, as in the first Procedure again the addition of temperature-sensitive components takes place. Table 4 shows this second method.
