Description

[Technical Field]

[0001] The present invention relates to hard surface cleaning concentrate packets and methods of making and using the same. In particular, the present invention relates to a hard surface cleaning concentrate packet comprising a water-soluble film and a concentrated hard surface cleaning composition, the concentrated hard surface cleaning composition comprising a compound represented by Formula I: R 1 -O-[CHCH(R 2 )O] a -H (I) [In the formula, R 1 is linear or branched C 2~8 is an alkyl group, and each R 2 is independently selected from the group consisting of hydrogen and a methyl group, and a is 1 to 3; and a glycol ether of formula II,

[0002] [ka] [Wherein, w is an average of 5 to 40, and R 3 is hydrogen and linear or branched C 1~20 alkyl groups, and R 4 is a linear or branched C 1~20 Alkyl groups and linear or branched C 1~4 hydroxyalkyl groups, and each R 5 are independently selected from the group consisting of hydrogen, methyl, ethyl, n-propyl, isopropyl, n-butyl, 2-butyl, and 2-methyl-2-butyl; 3 and R 4 and a tertiary amine, wherein the total number of carbon atoms in each of the groups is 5 to 21; and a water-soluble film encapsulating the concentrated hard surface cleaning composition.

[0003] Cleaning of hard surfaces is often accomplished by the use of surface cleaners that are applied directly to the surface and then wiped off with a cloth, squeegee, etc. Surface cleaners often contain various combinations of anionic surfactants, nonionic surfactants, amphoteric surfactants, solvents, and chelating agents. Other ingredients often include ammonia, acetic acid, and water.

[0004] Because surface cleaners are generally effective in solution with water, it is possible to provide a concentrate that can be mixed with water to form a cleaning solution. The concentrate may be packaged and shipped separately from the bulk of the water used to make the cleaning solution. The end user can then form the cleaning solution from the water and concentrate. The problem with concentrates is that they are ineffective unless they are mixed precisely to ensure the proper concentration of actives in the formed surface cleaner. If the solution is too dilute, cleaning performance may be reduced. If the solution is too concentrated, residue may be left on the cleaned surface. Furthermore, if the cleaning solution is too concentrated, the cleaning concentrate may be wasted.

[0005] To alleviate concerns about improper dilution of the cleaning concentrate, it has been found beneficial to package pre-measured single-use amounts of the cleaning concentrate in individual packages. The pre-measured amount of cleaning concentrate is preferably added to a specific amount of water to form an appropriately concentrated cleaning solution. Furthermore, the concentrate can be packaged in an appropriately sized container so that the user simply adds the cleaning concentrate to the container and fills the remainder of the container with water. When the container is empty, a replacement package of concentrate can be added to the container and the remainder can be refilled with water.

[0006] It has also been found useful to package cleaning concentrates in water-soluble packages, particularly in single-use, pre-measured amounts. Formation of a cleaning solution is facilitated by the use of water-soluble packages containing the concentrates, since the user simply adds the water-soluble package to a container and the appropriate amount of water to form the desired cleaning solution. When the water-soluble package dissolves, the cleaning agent is released, forming a cleaning solution having the appropriate concentration of cleaning agent.

[0007] One problem with conventional packaged hard surface cleaning concentrates in aqueous packages is that the hard surface cleaning formulations formed thereby are not particularly effective for cleaning oily and greasy soils from hard surfaces.

[0008] Thus, there remains a need for hard surface cleaning concentrate packets for use in formulated hard surface cleaning compositions that are effective in removing oily and greasy soils from hard surfaces.

[0009] The present invention provides a hard surface cleaning concentrate packet comprising a water-soluble film and a concentrated hard surface cleaning composition, the concentrated hard surface cleaning composition comprising a compound represented by Formula I: R 1 -O-[CHCH(R 2 )O] a -H (I) [In the formula, R 1 is linear or branched C 2~8 is an alkyl group, and each R 2 is independently selected from the group consisting of hydrogen and a methyl group, and a is 1 to 3; and a glycol ether of formula II,

[0052] Some embodiments of the present invention will now be described in detail in the following examples. Comparative Examples C1 to C10 and Examples 1 to 2 Concentrated hard surface cleaning composition

[0053] The concentrated hard surface cleaning compositions of Comparative Examples C1-C10 and Examples 1-2 were prepared by mixing the ingredients together in the weight proportions set forth in Table 1.

[0054] [Table 1]

[0055] Stain removal test To form the test solutions, the concentrated hard surface cleaning compositions of Comparative Examples C2, C5, C7, and C8 and Example 1, each with soil removal performance, were diluted with deionized water at a volumetric dilution ratio of 1:20. Following IKW recommendations, 1,500 μL of the greasy dust soil / tile was placed in an oven set at 120°C for 24 hours. The tiles were then removed from the oven and stored in a climate-controlled laboratory at room temperature for 24 hours before testing. The greasy dust soil used consisted of 75% by weight peanut oil, 23% by weight kaolin, and 2% by weight carbon black dispersed in isopropyl alcohol (20% by weight soil / 80% by weight isopropyl alcohol). Tests were performed using a scrubbing machine. For each test, 3 mL of the test solution was placed on a sponge (soft side), and the soiled tile was then rubbed 10 times with the surface of the sponge moistened with the test solution. The tiles were then rinsed under running tap water, and the test results were evaluated. The cleaning formulation of Comparative Example C2 performed best, followed by Comparative Examples C5, C8, C7, and Example 1. Note, however, that the formulation of Comparative Example C2 emits an ammonia odor upon dilution. The formulations of Comparative Examples C5 and C7 required heat to disperse the amine used. The formulation of Comparative Example C8 required heat to disperse the amine and precipitated from solution upon cooling to room temperature.

[0056] Stain removal test To form the test solutions, the concentrated hard surface cleaning compositions of Comparative Example C9 and Example 2, which exhibited soil removal performance, were diluted with deionized water at a volumetric dilution ratio of 1:20. Following IKW recommendations, 1,500 μL of the grease-dust soil / tile was placed in an oven set at 120°C for 24 hours. The tiles were then removed from the oven and stored in a climate-controlled laboratory at room temperature for 24 hours before testing. The grease-dust soil used consisted of 75% by weight peanut oil, 23% by weight kaolin, and 2% by weight carbon black dispersed in isopropyl alcohol (20% by weight soil / 80% by weight isopropyl alcohol). Tests were performed using a scrubbing machine. For each test, 3 mL of the test solution was placed on a sponge (soft side), and the soiled tile was then rubbed 10 times with the surface of the sponge wetted with the test solution. The tiles were then rinsed under running tap water, and the test results were evaluated. The cleaning formulation of Example 2 performed dramatically better than Comparative Example C9, demonstrating the dramatic impact of solvent choice on cleaning formulation performance.

[0057] Example 3 Concentrated hard surface cleaning composition The concentrated hard surface cleaning composition of Example 3 was prepared by mixing together the ingredients in the weight proportions set forth in Table 2.

[0058] [Table 2]

[0059] Stain removal test To form the test solution, the concentrated hard surface cleaning composition with soil removal performance of Example 3 was diluted with deionized water at a volumetric dilution ratio of 1:20. The cleaning performance of the cleaning solution of Example 3 was compared with that of three commercial products: Mr. Propre, St. Marc, and Ajax. Following IKW recommendations, 1,500 μL of greasy dust soil / tile was placed in an oven set at 120°C for 24 hours. The tiles were then removed from the oven and stored in a climate-controlled laboratory at room temperature for 24 hours before testing. The greasy dust soil used consisted of 75% by weight peanut oil, 23% by weight kaolin, and 2% by weight carbon black dispersed in isopropyl alcohol (20% by weight soil / 80% by weight isopropyl alcohol). Tests were performed using a scrubbing machine. For each test, 3 mL of the test solution was placed on a sponge (soft side), and the soiled tile was then rubbed 10 times with the surface of the sponge wetted with the test solution. The tiles were then rinsed under running tap water and the test results were evaluated. The cleaning formulation of Example 3 was significantly better than each of the commercial formulations on the greasy dust stains tested.
