Description

[Technical Field]

[0001] The present invention relates to a detergent compartment pouch comprising a biosurfactant and a water-soluble film comprising polyvinyl alcohol.

[0002] Background technology Detergent products in unit dose form have become one of the preferred forms for users due to their ease of use, especially water-soluble pouches which offer the added advantage of not needing to unpackage.

[0003] It is usually desirable to fill a water-soluble pouch with a liquid detergent solution, which limits the types of detergent compositions that are suitable for filling the pouch.

[0004] Quite often, some of the liquid "sweat" through the water-soluble film, creating a sticky surface.

[0005] Also, some liquid can diffuse through the water-soluble film into the second compartment filled with the powder composition, resulting in clumping and therefore not dissolving quickly and easily in soapy water during cleaning.

[0006] Therefore, the water content of the contained liquid detergent is usually reduced to a minimum and / or non-aqueous solvents are used as liquefying agents which further limits the amount of suitable detergent composition.

[0007] Additionally, the thickness of the water-soluble film is often increased to provide a more stable pouch, but this consumes more resources and does not contribute to the cleaning efficiency of the product.

[0008] Furthermore, for safety reasons, it is desirable to formulate a unit dose of detergent that does not dissolve too quickly in water to avoid swallowing the detergent content when small children are tempted by most colorful products to put the pouch in their mouths.

[0009] Therefore, there is a need to provide a detergent compartment pouch having a water-soluble film that is fairly resistant to the liquid detergent solution contained therein.

[0010] The object of the present invention is to design a detergent product that avoids the above problems.

[0011] MODE FOR CARRYING OUT THE INVENTION Surprisingly, it has been found that detergent compartment pouches with a water-soluble film comprising polyvinyl alcohol (PVOH) and containing a biosurfactant have outstanding properties with regard to their stickiness during long-term storage.

[0012] Accordingly, the present invention provides a detergent compartment pouch having at least one water-soluble film forming at least one compartment, wherein at least one compartment contains a liquid composition, said liquid composition comprising at least one biosurfactant, and said water-soluble film comprises polyvinyl alcohol.

[0013] The present invention further provides the use of a pouch according to the invention for washing the surface of an article,

[0014] One advantage of the present invention is that the detergent compartment pouches of the present invention exhibit improved shape retention and water resistance.

[0015] An advantage of the present invention is the better storage stability of the detergent compartment pouches of the present invention.

[0016] A further advantage of the detergent compartment pouch of the present invention is that the pouch can utilize thinner water-soluble films, thereby saving packaging materials.

[0017] Another advantage of the detergent compartment pouch of the present invention is that the contained liquid composition can be formulated without the addition of ethanolamine while maintaining its pourable liquid properties.

[0018] A further advantage of the present invention is that the dyes contained in the detergent compartment pouches according to the present invention exhibit improved color stability.

[0019] Another advantage of the detergent compartment pouch of the present invention is that the dyes contained in the detergent compartment pouch according to the present invention do not migrate to textiles during the washing process.

[0020] A further advantage of the present invention is that the dye contained in the detergent compartment pouch according to the present invention prevents children from eating the detergent pouch.

[0021] A further advantage of the present invention is that less dye can be incorporated into the detergent compartment pouch according to the present invention without significantly compromising the brilliance of the dye.

[0022] Accordingly, the present invention provides a detergent compartment pouch having at least one water-soluble film forming at least one compartment, wherein at least one compartment contains a liquid composition, said liquid composition comprising at least one biosurfactant; The detergent compartment pouch is characterized in that the water-soluble film comprises polyvinyl alcohol.

[0023] Within the context of the present invention, "biosurfactants" is understood to mean all glycolipids produced by fermentation. The term "biosurfactants" also encompasses glycolipids that are chemically or enzymatically modified after fermentation, as long as the glycolipid remains structurally intact.

[0024] The raw materials for producing the biosurfactants that can be used may be carbohydrates, in particular sugars, such as glucose, and / or lipophilic carbon sources, such as fats, oils, partial glycerides, fatty acids, fatty alcohols, long-chain saturated carbohydrates or unsaturated hydrocarbons.

[0025] In the context of the present invention, the term "surfactant" is understood to mean an organic substance having surface-active properties capable of reducing the surface tension of water to less than 45 mN / m at 20°C and at a concentration of 0.5% by weight based on the total composition. The surface tension is determined by the DuNouil ring method at 20°C.

[0026] In the context of the present invention, the term "liquid" is understood to be liquid at a temperature of 25° C. and a pressure of 1013 mbar.

[0027] Where average values ​​are specified below, these are number-averaged average values ​​unless otherwise specified.

[0028] Unless otherwise stated, percentages are given as percent by weight.

[0029] Wherever measurements are stated below, these are determined at a temperature of 25° C. and a pressure of 1013 mbar, unless otherwise specified.

Preferably, the liquid composition does not contain any detectable amount of MEA.

[0090] The pouch of the present invention has a water-soluble film that includes polyvinyl alcohol.

[0091] The polyvinyl alcohol may be partially acetalized or may be present in the form of a polyvinyl alcohol copolymer.

[0092] Suitable polyvinyl alcohols for inclusion in water-soluble films are commercially available, for example, under the trade names Solublon® (AICELLO-HARKE) and Mowiol® (Clariant).Water-soluble films containing polyvinyl alcohol are commercially available, for example, under the trade names Watersol® and MonoSol (Kuraray).Particularly suitable polyvinyl alcohols in the context of the present invention are, for example, Solublon® GS, Solublon® GA, Solublon® PT, Solublon® KC, Solublon® KL, Mowiol® 3-83, Mowiol® 4-88, Mowiol® 5-88, Mowiol® 8-88 and Clariant L648.

[0093] The polyvinyl alcohol preferably contained in the water-soluble film of the pouch of the present invention has a degree of hydrolysis of 70 mol% to 100 mol%, preferably 80 mol% to 90 mol%, particularly preferably 81 mol% to 89 mol%, and especially preferably 82 mol% to 88 mol%.

[0094] The polyvinyl alcohol preferably contained in the water-soluble film of the pouch of the present invention has a molecular weight in the range of 10,000 g / mol to 100,000 g / mol, preferably 1,000 g / mol to 90,000 g / mol, particularly preferably 12,000 g / mol to 80,000 g / mol, and particularly preferably 14,000 g / mol to 68,000 g / mol.

[0099] Preferably, at least one compartment in a detergent multi-compartment pouch according to the present invention contains a solid composition, while at least one other compartment contains the liquid composition. The composition preferably has a solid-to-liquid weight ratio of about 20:1 to about 1:20, more preferably about 18:1 to about 2:1, and even more preferably about 15:1 to about 5:1. Detergent multi-compartment pouches according to the present invention are highly versatile because they can accommodate compositions with a wide range of solid:liquid ratio values. Since many detergent ingredients are best suited for use in solid form, preferably powder form, detergent multi-compartment pouches with high solid:liquid ratios have been found to be particularly preferred. As defined herein, the solid:liquid ratio refers to the relationship between the weight of all solid compositions and the weight of all liquid compositions within the pouch.

[0100] Alternatively, the preferred solid:liquid weight ratio in the detergent multi-compartment pouch according to the present invention is from about 1:2 to about 1:18, more preferably from about 1:5 to about 1:15. These weight ratios are suitable when the majority of the detergent ingredients are in liquid form.

[0101] It has surprisingly been found that the diffusion of liquid from one compartment to the compartment or compartments containing the solid composition or compositions is significantly reduced, and thus the solid compositions contained in the form of a free-flowing powder do not agglomerate.

[0102] Enzymes are useful additives in cleaning compositions, such as dishwashing or laundry compositions.

[0103] The detergent compartment pouch according to the present invention preferably comprises at least one enzyme, preferably in a liquid composition which also comprises at least one biosurfactant.

[0152] The examples presented below are intended to illustrate the present invention, the scope of which is clear from the entire specification and claims, and are not intended to be limited to the embodiments embodied in the examples.

[0153] Working Example: Example 1: Shape retention and dissolution time measured upon contact with water. Preparation of liquid detergent formulations: The exemplary formulations described below were prepared according to the following protocol: First, a measured amount of water was introduced into an appropriately sized glass beaker. Then, components 1-5 were added with vigorous stirring at room temperature. All formulations contained components 2-5; components 1a, 1b, and 1c were added only to Test Formulation 1, Benchmark Formulation 1, and Benchmark Formulation 2, respectively. The order of addition to the solution is not important; therefore, the components were not added in any particular or uniform order. Any remaining amount of water was then introduced to ensure the desired concentration of the components. Finally, component 6 (monoethanolamine) was added to the solution, and the mixture was vigorously stirred at a temperature between 60 and 65°C for 1 hour. In the next step, the mixture was cooled to 35°C, and component 7 (citric acid) was added with continuous stirring until the pH of the formulation was adjusted to 8.0. Subsequently, component 8 (enzyme) was introduced into the formulation, and the mixture was stirred for 5 minutes to ensure a homogeneous solution. The exemplary compositions were easily pourable and stable at room temperature for extended periods.

[0154] Using the above method, three formulations were prepared: Test Formulation 1, Benchmark Formulation 1, and Benchmark Formulation 2. All of them were composed of similar ingredients at the same concentrations and differed by the type of anionic surfactant used, i.e., dirhamnolipid, sodium salt, linear alkylbenzene sulfonate, sodium salt, and sodium laureth sulfate in Test Formulation 1, Benchmark Formulation 1, and Benchmark Formulation 2, respectively. It is noteworthy that linear alkylbenzene sulfonate, sodium salt, and sodium laureth sulfate are standard surfactants routinely used in water-soluble pouch detergent formulations.

[0155] The rhamnolipid used was similar to dirhamnolipid, prepared as described in Example 1 of EP 3061442. Monorhamnolipid was prepared as in Example 2 of EP 3061442.

[0156] [Table 1]

[0157] Preparation of detergent pouches: Detergent pouches were fabricated using water-soluble PVOH foil. Two sheets of film were heat-sealed on three sides using a manual sealer to form a 6 cm x 10 cm pouch. The pouches were then filled with 25 g of liquid detergent solution (Test Formulation 1, Benchmark Formulation 1, or Benchmark Formulation 2) and closed using the heat sealer. The outer edge of the seal was then cut away to form the final pouch.

[0158] Solubility Test for Water-Soluble Pods: Prior to water solubility testing, pouches filled with Test Formulation 1, Benchmark Formulation 1, and Benchmark Formulation 2 were stored at room temperature and ambient humidity for 48 hours, allowing sufficient conditioning time for the liquid detergent content to affect the water-soluble film properties.

[0159] The test was performed according to the following protocol: For the test, 1 L of water was placed in a suitable glass container and conditioned to 40°C. The pouch containing the liquid detergent was attached by its corner to a metal holder and held freely in the hand. The pouch was then immersed in the water. It was ensured that the pouch hung vertically without touching the bottom of the glass container. No agitation was applied during the measurement. The time from immersion of the pouch in water to the first leakage of detergent was measured according to the test described. In addition, the time required for the immersed pouch to lose its physical shape and fall from the metal holder at the bottom of the glass container was also recorded. The average results recorded for the pouches containing each formulation are shown below.

[0161] As summarized above, the water-soluble pouches containing Test Formulation 1 surprisingly exhibit improved shape retention after immersion in water over pouches containing Benchmark Formulations 1 and 2. Thus, it has surprisingly been discovered that rhamnolipid-containing liquid detergents have a positive effect on the shape retention of water-soluble pouches by making them less susceptible to premature opening on contact with water.

[0162] Example 2: Monoethanolamine-free liquid formulation Preparation of liquid detergent formulations: The exemplary formulations described below were prepared according to the following protocol: First, a measured amount of water was introduced into an appropriately sized glass beaker. Then, components 1-5 were added with vigorous stirring at room temperature. All formulations contained components 2-5; components 1a, 1b, and 1c were added only to Test Formulation 2, Benchmark Formulation 3, and Benchmark Formulation 4, respectively. The order of addition to the solution is not important; therefore, the components were not added in any particular or uniform order. Any remaining amount of water was then introduced to ensure the desired concentration of the components. Finally, component 6 (sodium hydroxide) was added to the solution, and the mixture was vigorously stirred at a temperature between 60 and 65°C for 1 hour. In the next step, the mixture was cooled to 35°C, and component 7 (citric acid) was added with continuous stirring until the pH of the formulation was adjusted to 8.0. Subsequently, component 8 (enzyme) was introduced to the formulation, and the mixture was stirred for 5 minutes to ensure a homogeneous solution. The exemplary compositions were easily pourable and stable at room temperature for extended periods.

[0163] Using the above method, three formulations were prepared: Test Formulation 2, Benchmark Formulation 3, and Benchmark Formulation 4. All of them consisted of similar ingredients at the same concentrations and differed in the type of anionic surfactant used, thus dirhamnolipid, sodium salt, linear alkylbenzene sulfonate, sodium salt, and sodium laureth sulfate in Test Formulation 2, Benchmark Formulation 3, and Benchmark Formulation 4, respectively.

[0164] [Table 3]

[0165] Surprisingly, it was discovered that after cooling all three formulations (Test Formulation 2, Benchmark Formulation 3, and Benchmark Formulation 4), only Test Formulation 2 maintained its liquid properties, while Benchmark Formulations 3 and 4 solidified. Thus, Test Formulation 2 can be processed at room temperature and maintains its liquid properties after being placed inside a water-soluble pouch, while Benchmark Formulations 3 and 4 solidify at room temperature, thus preventing their use as liquid detergents for water-soluble pouches. Thus, it was surprisingly discovered that biosurfactants enable the formulation of concentrated liquid detergents for water-soluble pouches without the addition of monoethanolamine.

[0166] [Table 4]

[0167] The formulation is packaged in pouches according to the method of Example 1.

[0168] The pouches are stored uncovered on the laboratory bench for up to 3 months.

[0169] The pouches containing Benchmark Formulation 5 and Benchmark Formulation 6 have a noticeably lighter color compared to the pouch containing Test Formulation 3. The colorant containing rhamnolipid and pouches, Acid Blue 3, show better color brilliance compared to the others.

[0170] Further examples of formulations: Further exemplary liquid detergent compositions containing rhamnolipids were prepared according to the formulations listed in the table below. All exemplary formulations were then used to obtain water-soluble detergent pouches. To do this, two sheets of water-soluble PVOH film were heat-sealed on three sides using a manual sealing device to form a pouch measuring 6 cm x 10 cm. The resulting pouch was then filled with 25 g of liquid detergent solution (Formulation 1-26) and closed using a heat-sealing device. The outer edge of the sealing was removed by cutting to form the final pouch.

[0171] The sophorolipid used was sophorolipid REWOFERM SL ONE from Evonik, with a lactone to acid ratio of 40:60. The glucolipid was produced according to Example 2 of WO2019154970 via fermentation.
