Description

[Technical Field]

[0001] A water-soluble unit-dose article comprising a detergent composition containing a surfactant and a metalloproteinase. [Background technology]

[0002] Water-soluble unit-dose detergent articles are popular with consumers because they are convenient and efficient to use. Such water-soluble unit-dose articles contain a detergent composition encased in a water-soluble film. When a water-soluble unit-dose detergent article is added to water, the film dissolves / disintegrates, releasing the detergent into the surrounding water and creating a cleaning solution.

[0003] There are several reasons for formulating water-soluble unit-dose articles containing different detergent compositions, which can be determined by factors such as the availability of raw materials, the compatibility between raw materials, and the compatibility between raw materials and water-soluble films. Formulating higher levels of anionic non-soap surfactants compared to nonionic surfactants is typically advantageous for grease stain removal performance, but such a formulation approach typically presents challenges for enzyme-sensitive stain removal performance. Water-soluble unit-dose detergent articles should be formulated to provide good overall cleaning, i.e., cleaning of different types of stains, including both grease, sebum, and enzyme-sensitive stains, including protein stain removal and whiteness. [Overview of the project] [Problems that the invention aims to solve]

[0004] Therefore, there is a need to provide a new water-soluble unit-dose detergent article that offers good protein stain removal and good overall cleaning. [Means for solving the problem]

[0005] A water-soluble unit-dose detergent article comprising a water-soluble film and a liquid detergent composition, wherein the detergent composition is A water-soluble unit-dose detergent article comprising a non-soap surfactant system containing an anionic non-soap surfactant and a nonionic surfactant. The anionic non-soap surfactant is at least 80% by weight, preferably at least 90% by weight, of the anionic non-soap surfactant, Moisture content of less than 15% by weight of the composition Serine protease, Contains metalloproteinase, The weight ratio of non-soap anionic surfactants to nonionic surfactants is greater than 1.5:1.

[0006] The detergent provides excellent protein stain removal. [Modes for carrying out the invention]

[0007] Water-soluble unit quantity article This invention discloses a water-soluble unit-dose article comprising a water-soluble film and a liquid detergent composition, preferably a liquid laundry detergent composition. The water-soluble film and detergent composition will be described in more detail below.

[0008] A water-soluble unit-dose detergent article includes a water-soluble film molded such that the unit-dose article contains at least one internal compartment surrounded by a water-soluble film. The unit-dose article may comprise a first water-soluble film and a second water-soluble film sealed together to define the internal compartment. The water-soluble unit-dose article is configured to prevent the detergent composition from leaking out of the compartment during storage. However, when the water-soluble unit-dose article is added to water, the water-soluble film dissolves, releasing the contents of the internal compartment into the cleaning solution.

[0009] A compartment should be understood as a sealed internal space within a unit-dose article that holds the detergent composition. During manufacturing, the first water-soluble film may be shaped to include an opening compartment into which the detergent composition is added. Next, the first film is covered with a second water-soluble film in an orientation that closes the opening of the compartment. The first and second films are then sealed together along the sealing region.

[0010] A unit dose article may contain more than one compartment, more than two compartments, more than three compartments, or more than four compartments. The compartments may be arranged in an overlapping orientation, that is, one positioned on top of the other. In such an orientation, the unit dose article contains at least three films, one or more in the top, one in the middle, and one in the bottom. Alternatively, the compartments may be positioned in a side-by-side orientation, that is, one adjacent to the other. The compartments may also be oriented in a "tire and rim" arrangement, that is, the first compartment is positioned adjacent to the second compartment, but the first compartment at least partially surrounds the second compartment but does not completely enclose it. Alternatively, one compartment may be completely enclosed within another compartment.

[0011] If the unit-dose article has at least two compartments, one of the compartments may be smaller than the other. If the unit-dose article has at least three compartments, two of the compartments may be smaller than a third compartment, preferably with the smaller compartments overlapping the larger compartments. The overlapping compartments are preferably oriented adjacent to each other. The unit-dose article may contain at least four compartments, three of which may be smaller than a fourth compartment, preferably with the smaller compartments overlapping the larger compartments. The overlapping compartments are preferably oriented adjacent to each other.

[0012] In a multi-compartment orientation, the detergent composition according to the present invention may be contained within at least one compartment. For example, the detergent composition may be contained within one compartment, two compartments, or even three or four compartments. Alternatively, the detergent composition according to the present invention may be divided into different compartments so that the individual components can be combined in the cleaning solution at the time of use. For example, one compartment may contain a non-soap surfactant system according to the present invention, and another compartment may contain a metalloproteinase according to the present invention.

[0013] Each section may contain the same composition or different compositions. The different compositions may all be in the same form or in different forms.

Most preferably, the anionic non-soap surfactant does not contain alkyl sulfate and / or alkoxylated alkyl sulfate anionic surfactants, and in particular does not contain alkoxylated alkyl sulfate anionic surfactants.

[0032] When calculating the weight percentage or weight ratio of surfactants, the weight of neutralizing counterions is not considered in the case of anionic surfactants. For example, when calculating the weight percentage of anionic soap or non-soap surfactant or the weight ratio of anionic soap or non-soap surfactant to nonionic surfactant for anionic soap or non-soap surfactants, only the weight of the surfactant anion is considered.

[0033] Non-soap anionic surfactants include linear alkylbenzene sulfonates.

The ethoxylated alcohol nonionic surfactant may be linear or branched. In the branched chain form, the branching may be at position 1, position 2, or further down the alkyl chain, where the carbon position numbering begins from the carbon linked to the oxygen linker between the alkyl chain and the ethoxylated chain. The branching may be single-branched or multi-branched. Most preferably, the branching is single-branched at position 2. The branching is preferably alkyl-branched, more preferably methyl-branched, ethyl-branched, propyl-branched, butyl-branched, or pentyl-branched, most preferably a mixture thereof.

Peak-type alkoxylation and peak-type ethoxylation are also often used to describe the methods and materials used in their production. They can be produced industrially, for example, by adding ethylene oxide to an alcohol in the presence of a suitable catalyst (a calcined or fatty acid-hydrophobized layered compound). Examples of narrow-range alkoxylation catalysts include many alkaline earth (Mg, Ca, Ba, Sr, etc.) derived catalysts, Lewis acid catalysts such as zirconium dodecanoxide sulfate, and certain boron halide catalysts, such as those described by Dupont, in the form of MB(OR1)x(X)4-x or B(OR1)3 / MX (wherein R1 is an optionally substituted linear, branched, cyclic, or aromatic hydrocarbyl group having 1 to 30 carbon atoms, M is Na+, K+, Li+, R2R3R4R5N+, or R2R3R4R5P+, where R2, R3, R4, and R5 are independently hydrocarbyl groups, and x is 1 to 3). This process can be carried out for a variety of other hydrophobic materials and can be performed using various alkoxylation compounds (e.g., propylene oxide and butylene oxide) by modifying the catalytic properties.

The ethoxylated alcohol nonionic surfactant may be derived from a natural alcohol source, a synthetic alcohol source, or a mixture thereof. The most preferred natural sources include palm kernel oil, coconut oil, or a mixture thereof, with palm kernel oil being preferred. When the ethoxylated alcohol nonionic surfactant is derived from a synthetic alcohol source, the synthetic alcohol source is preferably produced via an oxo process, Ziegler process, Guerbet process, aldol condensation process, or a mixture thereof. The resulting alcohol can optionally, but preferably, be further fractionated to increase the C12-C15 content of the starting alcohol. Suitable examples of narrow-range ethoxylated alcohol nonionic surfactants are commercially available from Nouryon under the trade names Berol or Ethylan, and from Sasol under the trade name Novel.

While we do not wish to be bound by theory, non-Newtonian liquids have different properties from Newtonian liquids; more specifically, the viscosity of non-Newtonian liquids depends on the shear rate, whereas Newtonian liquids have a constant viscosity regardless of the shear rate applied. The decrease in viscosity of non-Newtonian liquids when shear is applied is thought to further promote the dissolution of the liquid detergent. The liquid laundry detergent compositions described herein may have any preferred viscosity depending on factors such as the components they are formulated with and the purpose of the composition.

[0071] The effect of metalloproteinases on stain removal was tested by varying the ratio of non-soap anionic surfactants to nonionic surfactants.

[0072] Cleaning test procedure using an automated turgotometer 1. One liter of hard water at a grain per gallon (GPG) of 8 US gallons was heated to 30°C and added to each turgot meter pot. 2. 1.1 g of detergent was added to the turgotometer washing pot, and then the enzyme was added as shown in Tables 1 and 2. 3. Eight CFT stain samples (5 x 5 cm) were added to a turgot meter pot (two samples per stain type: Pigment, Oil, Milk, POM (CFT C-10), Whole Egg with Aged Carbon Black on Cotton Fabric (CS-39), Aged Chocolate Soymilk (CSM) Drink on Cotton Fabric (CFT CS-45), and Aged Sheep's Blood (CFT CS-85) applied in a double layer to the cotton fabric). Subsequently, a 5 x 5 cm cotton knit ballast (supplied by Warwick Equest, Consett, United Kingdom) was added to obtain a fabric with a total load weight of 60 g. 4. The Turgotometer was set to mix at 208 RPM for 17 minutes to simulate the main cleaning process. 5. Next, the wash water was removed and replaced with 1 liter of 8-gallon grain (GPG) water at 15°C. 6. The turgotometer was set to mix at 208 RPM for 5 minutes to simulate the rinsing process. 7. Next, all the fabrics were removed from each pot. 8. Steps 1-8 were repeated three more times. 9. Tracers with CFT stains were separated from the cleaned ballast and air-dried overnight. 10. The dried stain was evaluated for stain removal using the L reading obtained with a shutter speed of 1 / 2 and aperture 8, calibrated before use, with DigiEye (VeriVide Ltd, Leicester, UK). * a * b * The readings were used to evaluate stain removal. * a * b * Measurements were taken for unwashed stains, washed stains, and unstained fabric, and Delta E calculations were performed to determine the level of stain for both unwashed and washed stains compared to the unstained fabric using the following formula. In the formula, suffix 1 indicates the value for the unstained, and suffix 2 indicates the value for the unwashed or washed stain. * The stain removal index (SRI) was calculated as a percentage of the level of stain removal as follows: SRI = 100×(A - B) / A.

[0073]

Equation

[0074] Where A = Delta E of the area of the fabric with unwashed stain A = Delta E of the stained area of the unwashed fabric * B = Delta E of the stained area of the washed fabric * .

[0075] Tables 3 and 4 show the stain removal results.

[0076] Test formulations:[[ID=G44]] Table 1 shows four metalloproteinase-free reference formulations with varying ratios of non-soap anionic surfactant to nonionic surfactant. Table 2 shows test formulations containing the relevant metalloproteinases. Examples E and F have non-soap anionic surfactant to nonionic surfactant ratios outside the scope of the present invention, while Examples 1 and 2 have non-soap anionic surfactant to nonionic surfactant ratios according to the present invention. All eight formulations also contain a certain level of serine protease. The metalloproteinases were added to the washing solution separately from the metalloproteinase-free base formulations.

[0079] Test results: Table 3 summarizes the stain removal performance of different test legs across a set of protease-sensitive stains. The table illustrates that in the absence of metalloproteinase, increasing the ratio of non-soap anionic surfactant to nonionic surfactant results in a significant decrease in performance. This significant decrease in performance is not observed further with the addition of a single change of metalloproteinase.

[0080] Table 4 summarizes the effect of single-change metalloproteinase addition on performance. The data in Table 4 show that the effect of metalloproteinases increases more strongly as the weight ratio of non-soap anionic to nonionic surfactants increases. A more robust overall performance profile across surfactant ratios is obtained in the presence of metalloproteinases.
