Description

[0001] HAND DISHWASHING LIQUID CONCENTRATE

[0002] The present invention relates to a liquid cleaning composition, in particular a concentrated liquid cleaning composition comprising at least one fatty alcohol ether sulfate, at least one betaine, and ethanol, wherein the concentrated composition has a salt concentration of about 0.2 to about 10 wt.% and wherein the concentrated composition can be diluted with water to form a ready-to-use liquid cleaning composition. The cleaning composition is preferably used for manual dishwashing. The present invention further relates to the use of such a cleaning composition for cleaning hard surfaces, in particular dishes, and to a process for producing a cleaning composition, wherein the process comprises diluting the concentrated liquid cleaning composition with water.

[0003] To minimize packaging, storage, and transport costs, many homecare products are now offered as concentrates containing a higher proportion of washing and cleaning active ingredients than conventional products. These concentrates are either used directly by the consumer for washing or cleaning, in which case a smaller amount, corresponding to the concentration, is required, or they are first diluted with a certain amount of water and only then used like a conventional product. In a number of countries, particularly those where the majority of people are low-income, concentrates are offered which, after dilution with water, are used by the consumer like conventional hand dishwashing detergents.Laundry and cleaning products offered in concentrate form thus represent an excellent solution for low-income consumers seeking financial relief, as the production, packaging, transport, and storage of concentrates are less costly than conventional product forms. For precisely these reasons, concentrates are also attractive to sustainability-conscious consumers who consider reducing emissions at least one of their priorities when making purchasing decisions.

[0004] In addition to the advantages mentioned that can be associated with concentrates, a corresponding product must, however, fulfill a complex requirement profile in order to be accepted by consumers. In addition to the primary washing and cleaning effect and transport and storage stability, consumers expect not only an attractive appearance, a pleasant fragrance and good skin compatibility, but also, in particular, ease of handling and dosing. For this reason, consumers prefer products with increased viscosity for a number of applications, e.g., manual dishwashing or the cleaning of other hard surfaces, especially after dilution with water. These products can be dosed more precisely and run more slowly on inclined and especially vertical surfaces, i.e., they have a longer effect on the surface to be cleaned. In addition, it is generally desired that the end product forms quickly, easily and without great effort (i.e.Light to moderate shaking of the aqueous mixture for only a few seconds without the need for repeated shaking) and that the final product, after dilution of the concentrate with water, exhibits favorable flow properties and no excessive bubbling and / or foaming. Furthermore, the diluted cleaning composition should also be storage-stable.

[0005] However, if the diluted concentrate is to have a sufficiently increased viscosity, this usually means that the viscosity of the undiluted concentrate is much higher and, accordingly, the handling properties and solubility of the concentrate are hardly or no longer acceptable.

[0006] Although a wealth of liquid cleaning agents in the form of concentrates are known in the art and widely marketed, there is still a need for improved compositions which, on the one hand, are readily flowable in concentrated form and, on the other hand, thicken themselves upon dilution with water to an extent that is perceived by the consumer as functional and easy to handle.

[0007] Surprisingly, it has been found that a specific salt concentration in the concentrated liquid cleaning agent composition leads to the desired properties with regard to the viscosity of the cleaning agent composition diluted with water. A salt concentration in the cleaning agent concentrate of about 0.2 to about 10 wt. %, preferably about 1 to about 7.5 wt. %, more preferably about 1.5 to about 6 wt. %, particularly preferably about 2 to about 4 wt. %, based on the active substance and the total weight of the cleaning agent concentrate, has proven particularly advantageous.

The index number b indicates the degree of oligomerization (DP), i.e. the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While b in a given compound must always be an integer and can mainly assume the values ​​b = 1 to 6, the value b for a specific alkyl glycoside is an analytically determined calculated value which is usually a fractional number.

Enzymes are advantageously present in the agent in an amount of approximately 1 x 10 -8 to about 5% by weight, based on active protein and total weight of the composition. More preferably, each enzyme is present in an amount of about 1 x 10 -7to about 3 wt.%, about 0.00001 to about 1 wt.%, about 0.00005 to about 0.5 wt.%, about 0.0001 to about 0.1 wt.%, and particularly preferably about 0.0001 to about 0.05 wt.%, based on active protein and total weight of the agent. Enzymes particularly preferably exhibit synergistic cleaning performance against certain soils or stains, ie, the enzymes contained in the agent composition support each other in their cleaning performance.

[0138] The composition according to the invention can be prepared by stirring the individual components together in any order. The order of addition is not critical for the preparation of the composition. Preferably, water, surfactants, and any other of the above-mentioned components are stirred together. If perfume and / or dye are used, these are subsequently added to the resulting solution. The pH is then adjusted as described above.

[0139] In preferred embodiments, the agent according to the invention for cleaning hard surfaces, in particular for cleaning soiled dishes, is applied in the form of a foam either directly onto the surface to be cleaned or onto a sponge, a cloth, a brush or another, optionally moistened, cleaning aid.

[0140] For the purposes of the invention, cleaning performance is understood as the ability of an agent to partially or completely remove existing soiling. Within the scope of the invention, both a cleaning agent concentrate or the diluted cleaning agent composition, as well as the cleaning liquor formed by these agents, have a respective cleaning performance. The cleaning performance can be determined using methods known to those skilled in the art.

[0141] The term "cleaning liquor" refers to the working solution containing the cleaning agent that acts on the surfaces to be cleaned, especially dishes, and thus comes into contact with the soiling present on the surfaces. The cleaning liquor is typically created when the cleaning process begins and the agent is diluted with water, for example, in a suitable container, preferably a sink for manual dishwashing.

[0142] Preferred embodiments of uses and agents according to the invention achieve such advantageous cleaning performance even at low temperatures, in particular in a temperature range from about 10°C to about 30°C, preferably about 15°C to about 30°C, preferably about 18°C ​​to about 25°C, particularly preferably about 25°C, very particularly preferably about 20°C.

[0143] Preferred embodiments include all liquid, gel-like, or pasty dosage forms of agents according to the invention, which may optionally also consist of multiple phases and may be present in compressed or non-compressed form, e.g., in the form of a non-aqueous cleaning agent or a non-aqueous paste, or in the form of an aqueous cleaning agent or a water-containing paste. Liquid agents are generally preferred. Furthermore, the agent may be present as a single-component system. Such agents consist of a single phase. Alternatively, an agent may also consist of multiple phases. Such an agent is therefore divided into multiple components.

[0144] In preferred embodiments, concentrated agents according to the invention can be in pre-portioned form (e.g. bags, pouches).

[0145] In preferred embodiments, the concentrated agent according to the invention is encased in pre-portioned form in a water-soluble coating. The water-soluble coating is preferably formed from a water-soluble film material selected from the group consisting of polymers or polymer blends. The coating can be formed from one or two or more layers of the water-soluble film material. The water-soluble film material of the first layer and the further layers, if present, can be the same or different. It is preferred that the water-soluble coating contains polyvinyl alcohol or a polyvinyl alcohol copolymer. Water-soluble coatings containing polyvinyl alcohol or a polyvinyl alcohol copolymer exhibit good stability with sufficiently high water solubility, particularly cold water solubility.Suitable water-soluble films for producing the water-soluble coating are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer whose molecular weight is in the range from 10,000 to 1,000,000 g / mol, preferably from 20,000 to 500,000 g / mol, particularly preferably from 30,000 to 100,000 g / mol, and especially from 40,000 to 80,000 g / mol. Polyvinyl alcohol is typically produced by hydrolysis of polyvinyl acetate, since a direct synthesis route is not possible. The same applies to polyvinyl alcohol copolymers, which are produced from polyvinyl acetate copolymers. It is preferred if at least one layer of the water-soluble wrapping comprises a polyvinyl alcohol whose degree of hydrolysis is 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol%, and in particular 82 to 88 mol%. In a preferred embodiment, the water-soluble packaging consists of at least 20 wt.-%, particularly preferably at least 40 wt.%, very particularly preferably at least 60 wt.% and in particular at least 80 wt.% of a polyvinyl alcohol whose degree of hydrolysis is 70 to 100 mol-%, preferably 80 to 90 mol-%, particularly preferably 81 to 89 mol-% and in particular 82 to 88 mol-%. A polymer selected from the group comprising (meth)acrylic acid-containing (co)polymers, polyacrylamides, oxazoline polymers, polystyrenesulfonates, polyurethanes, polyesters, polyethers, polylactic acid or mixtures of the above polymers can additionally be added to a polyvinyl alcohol-containing film material suitable for producing the water-soluble wrapping. A preferred additional polymer is polylactic acid. Preferred polyvinyl alcohol copolymers comprise, in addition to vinyl alcohol, dicarboxylic acids as further monomers. Suitable dicarboxylic acids are itaconic acid, malonic acid, succinic acid and mixtures thereof, with itaconic acid being preferred.Likewise preferred polyvinyl alcohol copolymers comprise, in addition to vinyl alcohol, an ethylenically unsaturated carboxylic acid, its salt or its ester. Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters or mixtures thereof. It may be preferred that the film material contains further additives. The film material can, for example, contain plasticizers such as dipropylene glycol, ethylene glycol, diethylene glycol, propylene glycol, glycerin, sorbitol, mannitol or mixtures thereof. Further additives include, for example, release aids, fillers, crosslinking agents, surfactants, antioxidants, UV absorbers, antiblocking agents, anti-adhesive agents or mixtures thereof. Suitable water-soluble films for use in the water-soluble wrappings of the water-soluble packaging according to the invention are films which are manufactured by MonoSol LLC, for examplesold under the designation M8720, M8630, M8312, M8440, M7062, C8400, or M8900. Also suitable are films sold under the designation SH2601, SH2504, SH2707, or SH2701 from Nippon Gohsei. Other suitable films include films with the designation Solublon® PT, Solublon® GA, Solublon® KC, or Solublon® KL from Aicello Chemical Europe GmbH, or the VF-HP films from Kuraray. The water-soluble coating preferably comprises at least partially a bittering agent with a bitterness value between 1,000 and 200,000, in particular those selected from quinine sulfate (bitterness value = 10,000), naringin (bitterness value = 10,000), sucrose octaacetate (bitterness value = 100,000), quinine hydrochloride, and mixtures thereof. In particular, the outer surface of the water-soluble coating is at least partially coated with a bittering agent with a bitterness value between 1,000 and 200,000.In this context, it is particularly preferable for the water-soluble casing to be at least 50%, preferably at least 75%, and most preferably at least 90% coated with the bittering agent having a bitterness value between 1,000 and 200,000. The bittering agent having a bitterness value between 1,000 and 200,000 can be applied, for example, by printing, spraying, or coating. According to the invention, the water-soluble casing has at least one continuously circumferential sealing seam that lies essentially in one plane. This is advantageous from a process engineering perspective, since for a circumferential sealing seam that lies essentially in one plane, only a single sealing step, possibly using only a single sealing tool, is necessary.The continuously circumferential sealing seam results in a better closure than wrappers with multiple sealing seams, and an excellent seal tightness of the sealing seam and thus of the wrapper itself. Leakage of product from the wrapper, e.g. onto the surface of the portion, would be disadvantageous, as the consumer would then come into contact with the product. However, this is precisely what should be avoided as far as possible with a washing or cleaning agent portion with a water-soluble wrapper. The water-soluble wrapper can preferably be made from at least two packaging parts. It is not necessary for the at least two packaging parts to be different. They can preferably be made from the same material and in the same way. In a preferred embodiment, this involves two parts of a water-soluble film, in particular two parts of a water-soluble film of the same composition.
