Description

The present invention relates to a three-phase strong laundry detergent wipe that enables controlled activation of a cleaning active substance and a method for producing the same.

The pursuit of hygiene has existed since the early days of mankind. Hygiene is, after all, an important aspect of everyday life. The hygienic approach is primarily to maintain good health. In addition to the general cleaning effect, the scent and improved detergency of the raw material composition have also been scrutinized for a wide range of possibilities. Detergency optimization is particularly characterized by improved cleanliness and the ability to prolong hygienic cleanliness.

Today's hygiene can be divided into areas of body, surface, and textile hygiene. The latter is divided into uses according to the textile material and color. At least since the 90s of the 20th century, consumers have become more aware of eco-cleaning. In this regard, it is desirable to retain the advantages of traditional cleaning detergents on the one hand and to find more innovative and ecologically feasible product solutions on the other.

With the start of industrial production, laundry detergents have been realized as powders. Today, powder laundry detergents consist of a mixture of different cleaning active substances.

Advances in the development of laundry detergents have led to the entry of enzymes and other new surfactant compositions into this market segment. Today, in addition to the substances needed for cleaning, large amounts of filling material are added. Therefore, there was no need to change consumer input behavior. The first attempt to eliminate the filling material resulted in an overdose of surfactant due to the user's habitual use.

Liquid cleaning detergents were then introduced that can be charged without residue and thus can provide a physical alternative to a solid mixture of laundry detergents. However, conventional liquid laundry detergents have not achieved the cleaning levels of strong laundry detergents (ie, solid mixtures). This is due to the fact that liquid cleaning detergents are limited to liquid components or components that are well soluble in water. The combination of essential substances lacking in cleaning detergents is a group of zeolites and their substitutes (eg, phyllosilicates and their derivatives). They lead to adsorption of dirt and a decrease in the hardness of water during use.

The current product trend is how to split laundry detergent. This can be achieved, on the one hand, by packing the liquid cleaning detergent in a small polymer pouch. However, the problem of missing zeolites mentioned above remains. Another physical modification of the laundry detergent is to mix the laundry detergent with fatty alcohols to obtain the desired shape. However, both product concepts describe one-phase products that can only be distinguished via input.

As disclosed in German Patent Application Publication No. 102010060126, polymorphic products can be provided. The laundry detergent wipes disclosed therein are characterized in that the carrier material is combined with an impregnating solution (two-phase product). However, even in this case, the problem of the missing zeolite still remains.

The German Patent Application Publication No. 10201301405 by the applicant discloses a significant improvement in the form of a three-phase strong laundry detergent wipe consisting of a dispersion (ie, a continuous liquid phase with a solid component) and a solid carrier material. There is. The dispersion is added to a substrate that is solid at ambient temperature. The carrier material can be a non-woven fabric, a fatty alcohol, or a substrate for a phase combination of a dispersion with additional separate phases. The first phase of the dispersion is a liquid cleaning detergent concentrate consisting of a cleaning active substance, an enzyme and optionally a bleaching agent, and the second phase of the dispersion is to support stain adsorption in solid modification. The builder or substance (eg, zeolite) of the third phase is the carrier substrate in solid modification at ambient temperature. The mixture of the first and second phases is added to the substrate, which can consist of viscose, polyethylene, polypropylene, or polyester. The solid phase of the dispersion, the second phase, is a functional component of the strong laundry detergent wipe. The substrate consists of a raw material that is used for statistical fixation of the dispersion and is solid at ambient temperature. In addition, all known ingredients of strong laundry detergent can be included. Multiple mixing of phases resulting in a three-phase strong laundry detergent wipe allows for the required statistically stable and homogeneous distribution by incorporation into water-insoluble builder liquid detergents and addition on substrates. ..

An object of the present invention is to improve the performance of such laundry detergents, especially sustainability (up to recyclability corresponding to the "cradle-to-cradle" approach), and thus, on the one hand, dispersions (liquids containing solid components). It is to provide a laundry detergent wipe having an optimized combination of a laundry detergent solution) and, on the other hand, the texture of the wipe. A further object of the present invention is to provide a laundry detergent wipe suitable for short cleaning programs.

Therefore, it is an object of the present invention to provide a laundry detergent wipe that allows for faster diffusion of the cleaning active ingredient and has dual sustainability characteristics due to its composition and its manufacture.

This object is achieved by the method for producing a three-phase strong laundry detergent wipe according to claim 1, wherein a dispersion is added to a carrier material which is solid at ambient temperature, and this method is described in the following (a) exothermic sacrifice. Steps to provide a liquid laundry detergent solution with an ingredient or soap and a water content of 10-30% by weight, (b) add a solid additive to the liquid laundry detergent solution using a disperser to add 1-10% by weight. A step of obtaining a dispersion having a solid content, wherein steps (a) and (b) are performed at ambient temperature to provide a carrier material consisting of the further (c) finite needle-like fibers below. (D) The steps (c) and (d) are carried out at ambient temperature, characterized in a step of adding the dispersion to the carrier material using a wetting device so that the carrier material statistically fixes the dispersion. Will be done.

These purposes are also the addition of a dispersion consisting of a heat-generating sanitizer or soap and a liquid laundry detergent solution having a water content of 10-30% by weight, which is solid at ambient temperature, and a solid additive. Achieved by a three-phase strong laundry detergent wipe containing a carrier material, the solid content of the dispersion is 1-10% by weight, and the carrier material is characterized by finite needle-like fibers.

A further advantageous aspect can be obtained from the dependent claims.

The term "laundry detergent solution", according to the invention, means a composition comprising one or more biocatalysts, preferably enzymes or cell extracts, particularly enzymes suitable for the production of laundry or detergents. Therefore, the three-phase strong laundry detergent wipes according to the present invention also contain one or more functional intact biocatalysts, in particular enzymes, in their compositions.

The term "ambient temperature", according to the invention, means a temperature range in which the biocatalyst is not irreversibly inactivated, preferably about 5-50 ° C, particularly preferably about 15-30 ° C.

According to the present invention, the term "%" means% by weight (w / w) unless otherwise specified.

The term "dispersion", according to the invention, preferably means a suspension, particularly preferably a suspension having a liquid phase as a continuous phase.

The term "exothermic saponification component" means, according to the invention, an exothermic saponification or neutralizing molecule, preferably an exothermic saponification or neutralizing fatty acid radical.

The term "average particle size" means, according to the invention, an average particle size D50 associated with an arithmetic mean, eg, Malvern Instruments Ltd. (Malvern, Worcestershire, UK) laser diffractometer "Mastersizer ™ 2000S" can be used to determine according to manufacturer data in accordance with ISO 13320: 2009 (eg, PQ Corporation Document ID). 7.1.1.2.ac133.E (Valleybrooke Corporate Center, Malvern, PA 19355-1740, USA)).

The term "diffusion", according to the invention, refers to the rate of transfer of the suspension to the wash water of use in the sense that the increase in the concentration of wash water is accelerated as compared to the prior art laundry detergent wipes. means.

Demonstrates the suitability of different laundry detergent forms for short cleaning programs, depending on the diffusion of the cleaning active material. Shows finite fibers relative to endless fibers.

The concept of sustainability is also currently being discussed in science as it makes sense to define this aspect for each application area through specific sustainability features. For laundry detergents, the central sustainability features are (i) resource conservation, (ii) duration of cleaning program (short cleaning program), (iii) amount of plastic (microplastic), (iv) distribution. It arises from (CO ₂ balance), (v) consumer addition (input), (vi) energy balance during production, and (vi) recyclability potential and extent. This means that a lightweight and compact cleaning detergent that can be converted into technical features and produced in low temperature processes should be provided. Therefore, the object of the present invention with respect to sustainability can be obtained from the sustainability features described below.

Resource Conservation Traditional forms of laundry detergent can be divided into powder, liquid laundry detergent, and pre-laundry detergent (such as laundry sheets / boards and polymer pouches filled with liquid laundry detergent). The composition of the powder is characterized in that, in part, it consists of sodium sulphate and similar substances used to improve injectability, these materials having no function with respect to cleaning activity. Liquid laundry detergents, on the other hand, contain significant amounts of water due to the desired viscosity, fluidity and therefore easy input. Pre-filled laundry detergents in the form of polymer pouches filled with liquid laundry detergents usually have high water and solubilizers (polypropylene glycol, glycerin), content and polymer (eg, polyvinyl alcohol), respectively, which Both are discarded in the wastewater along with the washing water (due to the dissolution process), but the washing sheet / board contains a significant amount of fatty alcohol and similar materials used to form the sheet / board through smelting. contains. The quantitative amounts of each non-cleaning active ingredient are summarized in Table 1.

In contrast, resource conservation should be to provide a laundry detergent with the highest possible cleaning active ingredients, and as far as core laundry requirements are concerned, fillers and drop media or molding materials are required. There are no or only small amounts of additives such as those listed in Table 1 above.

Short Wash Program The suitability of different laundry detergent forms for the short wash program, depending on the diffusion of the wash active material, is shown in FIG.

Powder and liquid cleaning detergents are typically introduced into the cleaning drum with water via the spray chamber. Inside the latter, they quickly become wash active and are therefore suitable for short wash programs. In contrast, the gel pouch is placed directly on the wash drum (along with the fabric) and becomes wash active only after the outer coating (usually polyvinyl alcohol) has been dissolved by water. This explains the delay in activation during the washing process. The laundry detergent wipe is also placed directly on the wash drum and releases the wash active material via diffusion when the wash water is sprayed onto the wash drum. Since the concentration of the cleaning active substance in the wipe decreases with time, the cleaning activity performance during the cleaning process decreases. However, fast diffusion of the pre-charged laundry detergent (in the case of the present invention, the detergent suspension) is required to be suitable for short cleaning programs.

Carrier materials that have been used in the field of wet wipes are characterized by hydrophilic characteristics because lotions are also hydrophilic (eg, wet baby wipes, wet cosmetic wipes, wet toilet wipes). Wet wipe products that allow fast diffusion of liquid lotions or suspensions are undesirable and therefore unknown in the art because the main purpose of these products is dirt adsorption. Only carrier materials with hydrophilic fibers and mixtures thereof are known, which can be distinguished by chemically (eg, using adhesives) binding fibers and water jets into needle-like fibers. However, for cost reasons, mixing of plastic fibers that strictly maintains the hydrophilic characteristics of the carrier material is also known.

Microplastics A further important subject is the presence and amount of microplastics in each product, which can be distinguished into primary (inside the product itself) and secondary (produced only during use) microplastics. Today, all laundry detergent products with a liquid main phase use polymers for stabilization (one-phase products). The same applies to the polymer pouch. It should be noted that these amounts are not shown in Table 1 above and should therefore not be considered fillers as they are the polymer components required for the product. In contrast, the laundry detergent wipes according to the invention described below, as far as sustainability is concerned, are first laundry products that do not contain polymers and thus neither primary microplastics nor secondary microplastics.

Distribution (CO ₂ balance)
The CO ₂ balance depends on the technical parameters of each laundry detergent and is based on the volume and mass of the physical units. Table 2 shows the amount of laundry detergent with respect to the average washing cycle (washing load) of standard laundry detergent.

To reach a low CO ₂ balance, the volume per wash cycle needs to be kept as small as possible.

Addition (input) by consumers
During the development of laundry detergents, laundry detergent concentrates have also been introduced. However, they were not accepted by consumers because the price level per cleaning load was quite high due to frequent overloads. This means that consumers clearly adopt the learned behavior patterns. On average, in the field of laundry powders and liquid detergents, an overload of 7% can be expected. In this regard, the addition form of the pre-filled laundry detergent is an advantage because it can significantly avoid environmental pollution due to erroneous loading.

Energy balance during production Perfect energy balance is always directly correlated with the edge cuts used. Two groups of high temperature and low temperature processes can be distinguished in relation to the value added during production. From the viewpoint of energy balance, it is recommended to use a low temperature process during the production of laundry detergent. This is only true for liquid laundry detergents, but the cleaning performance is quite low due to the inability to incorporate solid components, for example the absence of the above-mentioned zeolites. Laundry sheets / boards filled with laundry powder and liquid laundry detergents that allow the incorporation of solid components, as well as polymer pouches, are manufactured on a high temperature process. Therefore, all known laundry detergents, including solids such as zeolites, must be manufactured on a high temperature process. The production of laundry powder in the art can be carried out in two ways. In each case, a high pressure spraying process is used, where the slurry premixed from the heat resistant components of the laundry detergent is dried at 110-130 ° C. in a spray tower in a high temperature countercurrent, followed by the temperature sensitive components. Is added. This process is shown in Table 3.

A second method of producing a powder laundry detergent is carried out using an extruder for premixing the paste at 80-110 ° C, and then at 80-110 ° C the cylinder fitted in the rolling device It is formed into balls and then the temperature sensitive component is added again as in the first process. This second process is shown in Table 4.

The cleaning active ingredients of recycled laundry detergents are dissipated during addition, ie cleaning (decomposition of stains, transfer of stains, softening of water, bleached stains, etc.). Therefore, known eco-laundry detergents contain significant amounts of biodegradable components (eg, to obtain "Blue Angel"). Biodegradable components are also referred to in the laundry detergent industry as "between cradle" components because they are naturally converted into raw materials (CO ₂ and water). So far, the ingredients used in known laundry detergent products have only been recovered to some extent. The above fillers and other non-cleaning active ingredients cannot be recovered, for example, as can be seen from Table 5.

Technical Features of the Invention In view of the sustainability features described above, the object of the invention described above is to develop a pre-loaded laundry product that has been improved as far as its performance on the one hand and its sustainability on the other. be.

The laundry detergent wipe according to the present invention
As explained below
-Manufactured by a low temperature process (characteristic of energy balance sustainability)
-Contains a large amount of cleaning active substances (resource conservation / recycling sustainability characteristics),
-Low mass and volume (a characteristic of sustainability of CO ₂ balance) and-Suitable for short cleaning programs.

The laundry detergent wipes according to the invention include a carrier material consisting of finite fibers to increase the diffusion outlet points along the capillary cross section. To avoid fiber dissolution, a mechanically needle-processed material consisting of pure plastic recycled material with hydrophobic characteristics was used. Due to the improved diffusion (in the sense of faster diffusion of the cleaning active ingredient into the washing water), the laundry detergent wipes according to the invention are particularly suitable for short washing programs. As far as sustainability is concerned, the laundry detergent wipes according to the invention, on the one hand, are the first to combine a biodegradable cleaning active material with a fully recyclable carrier material (closed recovery material cycle of non-cleaning active carrier material). It is characterized by.

For the manufacture of laundry detergent wipes according to the present invention, to the carrier materials described above, which are solid at ambient temperature, consist of 100% recyclable finite fibers and allow faster diffusion of lotion during the washing process. , Dispersions characterized by the biodegradability of the raw materials and their low KVV _tox values (components of the dispersion are further disclosed below) are added. Manufacture provides a liquid laundry detergent solution (optionally a strong laundry detergent lotion) containing the following (a) exothermic saponifying ingredients or soaps and a liquid content of 10-30% by weight (eg water / glycerin). Step,
(B) A step of adding a solid additive to a liquid laundry detergent solution using a disperser to obtain a dispersion having a solid content of 1 to 10% by weight.
(C) A step of adding the dispersion to a carrier material consisting of 100% recyclable finite fibers using a wetting device so that the carrier material statistically fixes the dispersion.
, And steps (a)-(c) are performed at ambient temperature. The ratio of the average particle size of the solid additive to the respective diameters and gap widths of the openings of the wetting device is in the range 5 × 10 ^-4 : 1 to 15 × 10 ^-4 : 1.

The laundry detergent wipe according to the present invention obtained by this manufacturing method is
-A liquid biodegradable laundry detergent solution containing a small amount of non-cleaning active ingredient, which is also mainly biodegradable,
-Natural solids to improve cleaning activity performance,
-Consisting of finite 100% recyclable fibers and free of primary and secondary microplastics, preferably hydrophobic carrier materials (without coatings such as hydrophilization),
including.

The absence of microplastics was established by Institute Hownstein in the following manner. Samples were cut from a dry carrier material (2.44 gr to 5.49 gr consisting of recyclable monopolymers in the form of finite needle-like fibers) and mixed with 50 ml of distilled water. Microscopy was performed via squeezed compounds (Jenamed-II up to 600x magnification and Nagaotte counting chamber).

The use of finite fibers 5-10 cm in length fixed by mechanical needling for addition in short wash programs is particularly useful as more diffusion emission points are generated along the cutting length. there were. Needlings then provided the necessary stability to avoid dissolution of the fibers and thus residues on the fabric. FIG. 2 shows such fibers relative to endless fibers.

This diffusion improving effect is achieved by adding a dispersion to a) a carrier material of finite needle-shaped fibers with strong diffusion and b) an endless fiber carrier material, and then adding 500 mL of tap water at a temperature of 21.3 ° C. Was determined experimentally by immersing in a 1 L container filled with the above for 60 seconds and then stirring the air using a mixer (BOSCH 450 W, with stirring staff, stirring diameter 4 cm) set to operation mode 5 for 60 seconds. .. After that, each laundry detergent wipe was carefully removed, and the laundry detergent solution was drained for 10 seconds in each case. The higher the foam formation, the more surfactant diffused into the aqueous phase within the same period and the lotion was the same. This experiment was performed 10 times per mutant. Table 6 shows the average foam formation compared.

From the above, it can be seen that the finite needle-like fibers resulted in a significant increase in the emission diffusion coefficient of 1.71. The use of shorter finite fibers promotes diffusion, but improves the stability of needle-like compounds. The experimental results shown in Table 6 describe the ideal ratio between emission and diffusion of finite fiber carrier material stabilized by mechanical needling.

Table 7 shows examples of formulations for liquid laundry detergent solutions manufactured in the first process step and successfully used in the cold production of laundry detergent wipes according to the invention. Detailed examples can be obtained from the last embodiment of the specification.

In the second process step, 1-10% by weight of solids is incorporated into this liquid laundry detergent solution by stirring and / or dispersion to obtain a dispersion. Again, no heat input was required. Solids (zeolites, phyllosilicates, and their derivatives) are also cleaning active ingredients.

In the third process step, the dispersion prepared according to the above is added to the carrier material to obtain a laundry detergent wipe according to the present invention. Hereinafter, the expressions in Table 8 will be described in more detail. It should be noted that for some applications (such as "general purpose" and "white" at the end of this specification), the dispersion can contain oxygen donors and bleaching agents which can be activators thereof. ..

As can be seen from the figure, the method can be performed at ambient temperature throughout. First, a liquid laundry detergent lotion with a heat-generating saponified component and a water content of 25% by weight is produced, or water-free by adding the soap already provided. The water content can also be higher or lower, generally in the range of 10-30% by weight.

Then, a solid additive such as zeolite, phyllosilicate, etc. is added to this lotion using a disperser to produce a dispersion, and the solid content of the dispersion is preferably 5% by weight and is solid. Minutes can also be higher or lower, generally in the range of 1-10% by weight. However, for optimal and efficient production, on the one hand, solids such as zeolites (and phyllosilicates and their derivatives, respectively) have an average particle size that grows into a liquid lotion by aggregation during agitation. On the other hand, the dispersion (solid in the liquid phase) is added to a finite carrier material such as polyester from 100% recycled material (especially PET) with an average fiber length of 5-10 cm and a wetting device such as a wetting rod. The diameter in the case of a circular opening or the gap width in the case of a rectangular opening (ie laterally) must be stabilized by mechanical needling in a further step through the line, taking into account pump performance. Should be kept as small as possible for good results, but this can result in closure of the openings due to the aggregation of zeolites, as a result of which mass production seems impossible. Seems to be. For this reason, aggregated solids are not used in the production of wet wipes in the prior art. (This problem does not occur in the production of common powder laundry detergents where zeolite is replaced by tenside.)

In a preferred embodiment of the manufacturing method, physical control of the velocity theory of agglomeration solves the above problem of agglomeration facing a small opening gap width: on the other hand, of dual sustainability. For the characteristic diffuse laundry detergent wipes, we used for the first time a disperser, primarily for finely distributing particles inside biodegradable lotions. The fine distribution in the dispersion was further supported by using the smallest possible particles. For the manufacture of laundry detergent wipes according to the present invention, the ratio of the particle size to the diameter of the circular opening (or the gap width of the rectangular opening of the wet rod) is 5 × 10 ^-4 : 1 ^to 15 × 10-. It ranges from ⁴ : 1 (eg, the average size of the particles in diameter is 1 μm to 5 μm, or the gap width of the rectangular opening of the wet rod is 2 mm), with a particularly favorable ratio of 8 It was .5 * 10 ^-4 : 1 (eg, the average size of the particles in diameter is 1.7 μm and the gap width of each opening of the wet rod is 2 mm).

In connection with production, hydrophobic carrier materials in the form of finite needle-like fibers, eg, 7 cm long, were suitable. In particular, polyester fibers made of 100% recycled products (particularly PET) should be mentioned. These materials can be processed in the form of finite needle-like fibers (no dissolution, no microparticles) so that work that does not avoid putting the polymer in groundwater is adhered to. In addition, the carrier material is removed by the user after the cleaning process and therefore meets the criteria for adding carrier material to plastic / packaging waste. Thus, this non-washing active ingredient can be completely recycled, as opposed to, for example, a pre-injection detergent in the form of a polymer pouch. Moreover, it is possible for the first time to use a carrier material made 100% from old plastic. This is especially surprising as one would initially think that material characteristics would be adversely affected due to recycling (eg tear strength, capillarity, etc.).

In view of the sustainability features described above, the product definitions of laundry detergent wipes according to the invention are shown in Table 9 showing embodiments that are particularly suitable for manufacture.

The overview according to Tables 10 and 11 as compared to current laundry products shows the individual substances and total mass released to the environment (via wash water) during addition.

Table 12 shows the resulting cumulative use of resources by non-cleaning active materials depending on the form of addition.

Cold production of laundry detergent wipes, as well as avoidance of overfilling, is achieved by predetermined loading. Due to the use of biodegradable cleaning active ingredients (“between cradle”) in combination with the carrier material closed recovery material cycle, the laundry detergent wipes according to the invention are completely new pre-laundry detergents and have dual sustainability. Has a function. For the first time, the use of non-woven fabrics made of finite fibers for wet wipes can achieve the promotion of diffusion of cleaning active ingredients, making the present invention particularly suitable for short cleaning programs.

The eco-friendliness of the new laundry detergent wipes can be characterized by KVV _tox values. In contrast, conventional laundry detergents have a value of about 5000 and laundry detergent wipes have a value of less than 1000. The KVV _tox value represents the amount of water required to dilute the laundry detergent per wash load to avoid adverse effects.
