Description

Technical Field

[0001] The present invention belongs to the technical field of daily chemical products, and particularly relates to a washing composition and a method for manufacturing the same.

Background Art

[0002] Conventional washing products include products in various forms. For example, they include washing powder, laundry soap powder, soap and / or laundry sheets in block or sheet form, washing liquid in liquid form, and laundry beads (also called detergent capsules). Laundry beads and laundry sheets are easy to carry, but laundry beads require sealing the laundry materials with PVA film, which increases the plastic content and may have an impact on the environment. Laundry sheets are a new type of laundry product formed in a different form, and laundry sheets are characterized by a high content of activators. Laundry sheets in sheet form can be obtained by drying the laundry sheet raw material at high temperature. Laundry sheets have the advantages of being easily dissolved in water, being easy to carry, being easy to measure, and not requiring high transportation costs, and are attracting the attention of users. As described above, laundry sheets in sheet form are manufactured by drying the laundry sheet raw material at high temperature. With reference to the stain removing laundry composition and its manufacturing method and laundry sheet described in the specification of the Chinese patent application with patent publication number CN117363432A, the laundry sheet raw material needs to be heated to 90-105°C to form the laundry sheet. The heating process may cause the enzyme to become less stable, and some of the enzymes may become inactive. Therefore, it is not easy to select a suitable enzyme, and the amount of enzyme added needs to be increased. In addition, since the conventional laundry sheet adopts a high-temperature manufacturing process, it is not possible to add essence microcapsules with good fragrance retention function to the laundry sheet, and normal essence must be added to achieve the fragrance retention function. The addition of normal essence increases the consumption of surfactants, which reduces the stain removing power of the laundry sheet.The main components of the laundry sheet are anionic surfactants or nonionic surfactants. Since the main component of the fabric softener is a cationic surfactant, if the fabric softener is directly added to the laundry sheet, the fabric softener will consume the anionic surfactant, resulting in a decrease in the stain removal power of the laundry sheet and a decrease in the fabric softening effect.

[0003] Therefore, it is necessary to improve the conventional technology.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to solve the drawbacks of the conventional technology, the object of the present invention is to provide a laundry composition and a method for manufacturing the same, so as to solve the drawback that the conventional laundry sheet has few functions.

Means for Solving the Problems

[0005] To achieve the above object, the present invention adopts the following technical matters. The laundry composition of the present invention includes a packaging material, functional components packaged inside the packaging material, and an adhesive for adhering the packaging material. The packaging material is a film-forming material having a washing function. The functional components include any one or more of softening particles, fragrance-retaining particles, active oxygen particles, and enzyme preparations.

[0006] In the laundry composition, the weight ratio of the packaging material to the functional components is 1:(1 - 3).

[0007] In the laundry composition, the functional components are composed of softening particles, fragrance-retaining particles, active oxygen particles, and enzyme preparations, and the weight ratio of the softening particles, fragrance-retaining particles, active oxygen particles, and enzyme preparations is 1:(2 - 4):(0.1 - 2):(0.01 - 0.5).

[0008] In the washing composition, when the raw materials for manufacturing the packaging material are measured by mass percentage, the raw materials for the packaging material include 1 to 5% of a first film-forming agent, 10 to 20% of a second film-forming agent, 10 to 30% of a surfactant, 1 to 10% of a stretching agent, 0 to 5% of an antibacterial agent, and 0 to 1% of a pigment, and the balance is water.

[0009] In the washing composition, the first film-forming agent is any one or more of polyvinyl alcohol, polyethylene ether, or polyvinyl pyridine compounds.

[0010] In the washing composition, the second film-forming agent is any one or more of cationic modified starch, modified cellulose, modified hemicellulose, and modified lignin.

[0011] In the washing composition, the surfactant is any one or more of sodium dodecyl sulfate, sodium dodecyl sulfonate, α-olefin sulfonate, betaine-type amphoteric surfactant, amino acid surfactant, and aliphatic alcohol polyoxyethylene ether compound.

[0012] In the washing composition, the stretching agent is any one or more of glycerol or its polymer, alkyl glycoside, or low molecular weight block polysiloxane.

[0013] In the washing composition, the antibacterial agent is any one or more combinations of tropolone, curcumin, dichlorosan, or chloroxylenol.

[0014] The present invention further provides a method for manufacturing a washing composition for manufacturing the washing composition. The method for manufacturing the washing composition includes manufacturing a packaging material, manufacturing an adhesive, and packaging functional components. In the packaging of the functional components, first, the functional components are placed on one piece of packaging material, and an adhesive is applied to the edge of the sheet-shaped packaging material. Next, another piece of packaging material is placed on the packaging material, and by pressing the edge of the packaging material, a sealed structure composed of two pieces of packaging material is formed to obtain a washing composition.

Advantages of the Invention

[0015] In the laundry composition and its manufacturing method of the present invention, by packaging the functional components with a packaging material having a cleaning function, the laundry composition can simultaneously exhibit a dirt-removing function, a softness-retaining function, and an aroma-retaining function. Also, since the softening particles, aroma-retaining particles, active oxygen particles, and enzyme preparations in the functional components are not directly added to the packaging material, when the packaging material is molded at a high temperature, it is possible to prevent the functional components from becoming ineffective, and to solve the problems that the effects of the functional components directly added to the conventional laundry sheet are reduced or the cost is high. Further, by packaging each functional component with the packaging material, it is possible to prevent the exposure of each functional component. In particular, by preventing the active oxygen particles and enzyme preparations from coming into contact with air, the functions of each functional component can be maintained.

Modes for Carrying Out the Invention

[0017] The present invention provides a laundry composition and its manufacturing method. To explain the object, technical matters, and advantages of the present invention in more detail and clearly, the present invention will be described in detail in the following examples. It should be noted that the following specific examples are for explaining the present invention and do not limit the present invention.

[0018] In the prior art, in order to increase the additional functions of laundry sheets, additional components are added to the raw materials of the laundry sheets. For example, in order to ensure the fragrance retention function and the softness retention function of the laundry sheets, essence (or essence microcapsules or fabric softener components) is added to the raw materials of the laundry sheets, or active oxygen particles or enzyme preparations can be added to the raw materials of the laundry sheets in order to increase the washing function of the laundry sheets. When manufacturing the laundry sheets, first, each component is evenly stirred to form a molten raw material. Next, the molten raw material is dried at a high temperature to obtain a sheet-shaped laundry sheet. When manufacturing the laundry sheets, it is necessary to heat the molten raw material to 100 °C or higher. By heating the molten raw material to that temperature and stirring it, there is a risk that the active oxygen particles and the enzyme preparations will become ineffective. In addition, due to the high temperature and stirring, the essence microcapsules may burst and release in advance, resulting in the loss of the fragrance retention function of the laundry sheets. As a result, the laundry sheets lose functions other than the washing function, so it is necessary to increase the addition amount of the additional components to obtain a predetermined function. As a result, the cost increases. Also, when adding free essence instead of essence microcapsules as the fragrance retention component of the laundry sheets, there is a risk that the surfactant will decrease due to the free essence. As a result, the washing function of the laundry sheets will decline.

[0019] Therefore, in the first exemplary embodiment of the present invention, the following detergent composition is provided. The shape of the detergent composition is any one of sheet-like, block-like, and bead-like, and the specific shape of the product can be set according to actual needs. The detergent composition includes a packaging material, functional components packaged inside the packaging material, and an adhesive for adhering the packaging material. The proportion of the packaging material and the functional components can be arbitrarily adjusted according to actual functional needs. To ensure the packaging performance of the packaging material, when the ratio of the weight of the packaging material to the weight of the functional components is 1:(1~3), the packaging material can well enclose the functional components inside the packaging material and ensure the washing function and other auxiliary functions of the detergent composition. The packaging material is a film-forming material having a washing function. For example, a sheet-like laundry film or laundry sheet can be manufactured from the film-forming material. By dissolving the packaging material in water, the washing and stain-removing functions of the detergent composition can be exerted, and since the packaging material has a good molding effect, it can prevent the detergent compositions (packaged with the packaging material) from adhering to each other. The packaging material needs to have a certain flexibility and stretchability. Since the packaging material has good tensile strength, a space for storing the performance components can be formed by adhering one or two packaging materials. Thereby, a sheet-like, block-like, or bead-like detergent composition having functions such as washing, softening enhancement, fragrance retention, disinfection, and prevention of color mixing can be obtained. The functional components can include any one or more of softening particles, fragrance retention particles, active oxygen particles, and enzyme preparations, and it is preferable to include a plurality of them. Since the functional components are enclosed inside the packaging material, the detergent composition can have good softening property, fragrance retention property, or washing effect. The adhesive can enclose the functional components inside the packaging material by sealing the opening or edge of the packaging material.

[0020] By packaging the functional components with a packaging material having a washing function, the washing composition can simultaneously exhibit a stain removal function, a softness retention function, and an aroma retention function. In addition, since particulate softening particles, aroma retention particles, active oxygen particles, and enzyme preparations are not directly added to the packaging material, when the packaging material is molded at a high temperature, the functional components are prevented from becoming ineffective, and the problems of the reduced effect or high cost of the functional components directly added to the conventional laundry sheet can be solved. In addition, by packaging each functional component with a packaging material, the exposure of each functional component can be prevented. In particular, by preventing the active oxygen particles and enzyme preparations from coming into contact with air, the functions of each functional component can be maintained. By adjusting the amounts of the packaging material and the functional components, the washing composition can obtain a washing material having a predetermined amount, and can improve the portability and usability of the washing composition. When using the washing composition, by adding one or more washing compositions according to the amount of the laundry, functions such as washing, softness maintenance, aroma retention, and sterilization can be exhibited.

[0021] Since the packaging material not only serves to enclose the functional components inside the packaging material but also has the function of washing, it is necessary to have good molding effect, flexibility or stretchability, and the amount of surfactant contained in the packaging material should not be reduced. Conventional laundry sheets have good stretchability by using polyvinyl alcohol as a carrier. However, since conventional laundry sheets do not dissolve easily in water, they cannot improve the washing effect. Therefore, reducing the amount of film-forming materials such as polyvinyl alcohol and improving the molding effect and washing effect of the packaging material have become issues that need to be solved. In a preferred embodiment of the present invention, when the raw materials for manufacturing the packaging material are measured by mass percentage, the raw materials of the packaging material include 1-5% of a first film-forming agent, 10-20% of a second film-forming agent, 10-30% of a surfactant, 1-10% of a stretching agent, 0-5% of an antibacterial agent, 0-1% of a pigment, and the balance is water. The first film-forming agent can be any one or more of polyvinyl alcohol, polyvinylether, or polyvinyl pyridine compounds, but is not limited thereto. For example, the first film-forming agent can also be other organic compounds having a film-forming function. The film-forming material has the characteristic that although the addition amount is small, the film-forming effect is good. The second film-forming agent can be any one or more of cationic modified starch, modified cellulose, modified hemicellulose, modified lignin, but is not limited thereto. For example, the second film-forming agent can also be a substance having a film-forming function and capable of being decomposed by the environment.The substance has a film-forming function and is biodegradable by microorganisms when dissolved in water, so it is environmentally friendly. When the film-forming agent is dissolved in water, the film-forming agent has a gelling or flocculation function, so it can adsorb anionic pigments and prevent color mixing. The stretching agent can be any one or more of glycerol or its polymer, alkyl glycoside, or low molecular weight block polysiloxanes, but is not limited thereto. For example, the stretching agent can also be other compounds having the same function. The stretching agent can improve the stretchability of the packaging material and prevent cracks in the packaging material by affecting the first film-forming agent and the second film-forming agent. Thereby, the sealing effect of sealing the functional components with the packaging material can be improved. The surfactant can be any one or more of sodium dodecyl sulfate, sodium dodecyl sulfonate, α-olefin sulfonic acid salts, betaine amphoteric surfactants, amino acid surfactants, fatty alcohol polyoxyethylene ether compounds, but is not limited thereto. For example, the surfactant can also be other substances having the same function. Such a surfactant has a good washing effect and can well remove stains on clothes, so the clothes can be washed clean.The bacteriostatic agent is any one or a combination of tropolone, curcumin, diclosan (HP-100), or chloroxylenol (PCMX). As a result, the washing composition has good bacteriostatic performance.

[0022] The packaging material does not use polyvinyl alcohol that is not easily decomposed, but uses cationic modified starch, modified cellulose, modified hemicellulose, and modified lignin that are easily decomposed. By using a stretching agent together, the amount of the first film-forming agent that is difficult to decompose can be significantly reduced, and the purpose of reducing the amount of plastic used can be achieved. In addition, since the packaging material has good molding effect and flexibility, the functional components can be well encapsulated inside the packaging material. Also, film-forming agents such as cationic modified starch, modified cellulose, modified hemicellulose, and modified lignin have the function of gelation or aggregation, so they can adsorb anionic dyes and prevent color mixing.

[0023] In a preferred embodiment of the present invention, since the functional components are composed of softening particles, fragrance-retaining particles, active oxygen particles, and enzyme preparations, the washing composition has various functions, can increase the dirt removal effect, ensure the softness of clothes, and can retain the fragrance for a long time.

[0024] In a preferred embodiment of the present invention, the weight ratio of the packaging material to the functional components is 1:2, and the weight ratio of the softening particles, fragrance-retaining particles, active oxygen particles, and enzyme preparations is 1:(2 - 4):(0.1 - 2):(0.01 - 0.5). By adopting a washing composition in which the weight ratio of the functional components is the above ratio, the removal of dirt and the softness of clothes can be well ensured, and the fragrance can be retained for a long time.

[0025] In a preferred embodiment of the present invention, the active oxygen particles in the functional component are particulate materials formed by using percarbonate or persulfate as a base material and wrapping a water-soluble inert film on the surface of the base material. When the active oxygen particles are put into water, oxygen is released, thereby decomposing organic stains and improving the cleaning effect of the washing composition.

[0026] In a preferred embodiment of the present invention, the enzyme preparation in the functional component can be any one or more of protease, cellulase, amylase, lipase, and pectinase. By the cooperation of such an enzyme preparation and a surfactant, the cleaning effect of clothes can be ensured, and even if the usage amount of the washing composition is reduced, a better cleaning effect can be obtained.

[0027] In a preferred embodiment of the present invention, the enzyme preparation is a combination of protease, cellulase, amylase, lipase, and pectinase provided by Novozymes, and the weight ratio of protease, cellulase, amylase, lipase, and pectinase is 5:5:3:1:1. By adopting the particulate enzyme preparation with the weight ratio being the above ratio, the cleaning effect can be ensured.

[0028] In a preferred embodiment of the present invention, the fragrance-retaining particles in the functional components are essence microcapsules, which can easily adhere to the surface of clothing. When the fragrance-retaining particles rupture due to friction, they release fragrance, and the fragrance can be released for a long time. Preferably, the fragrance-retaining particles are fragrance-retaining particles composed of essence of type D, type I or type E of HALOSCENT shipped by Firmenich. When the fragrance-retaining particles come into contact with oxygen, they release various fragrances, ensuring the diversity of the fragrance and enabling the fragrance to be released for a long time.

[0029] In a preferred embodiment of the present invention, the softener particles in the functional components are high-concentration softener beads. It is preferable to adopt the WS series of softener beads manufactured by Magic Crystal Company (Foshan Magic Crystal Technology Development Co., Ltd.) in China as the softener. This is because the softener has the advantage of being able to well ensure the softness of clothing.

[0030] In a preferred embodiment of the present invention, the adhesive contains an antibacterial agent, cationic modified starch or modified cellulose. The antibacterial agent is dichlorosan (HP-100) or chloroxylenol (PCMX), so it has the functions of antibacterial and antiseptic. Cationic modified starch or modified cellulose has the function of adhesion and can prevent color mixing.

[0031] The present invention further provides a method for manufacturing a laundry composition. The method for manufacturing the laundry composition includes the manufacture of packaging materials, the manufacture of adhesives and the packaging of functional components.

Table 1

[0075] As shown in Table 1, the stain removal power of the washing compositions of Examples 1 to 9 depends on the addition amounts of the surfactant, active oxygen particles, and enzyme preparation. The more the addition amounts of the surfactant, active oxygen particles, and enzyme preparation increase, the stronger the stain removal power of the washing composition becomes. As shown in Comparative Ratio 1, the component ratio of Comparative Ratio 1 is the same as that of Example 1, but as the manufacturing method of the washing composition, by using the method of stirring each component into a molten state and then compressing them to mold the washing composition, the stain removal power of the washing composition is significantly reduced. As described above, after manufacturing the packaging material and the functional components respectively, by packaging the functional components with the packaging material, the stain removal power of the washing composition can be ensured.

[0076] Table 2 Decrease value of the straight-line bending length

Table 2

[0077] As shown in Table 2, the decrease value of the straight bending length of the washing compositions of Examples 1 to 9 is related to the addition amount of the softener. The more the addition amount of the softener increases, the more the decrease value of the straight bending length of the washing composition increases. As shown in Comparative Example 1, since the conventional manufacturing method is adopted in Comparative Example 1, even if the same component ratio of the softener is adopted, the difference in the softness ensuring effect becomes very large. By packaging the softener component with the packaging material, it is possible to prevent the softener from becoming ineffective.

[0078] Table 3 Static fragrance retention strength

Table 3

[0079] As shown in Table 3, the fragrance retention effect of the washing compositions of Examples 1 to 9 is related to the addition amount of the fragrance retention particles. The more the addition amount of the fragrance retention particles increases, the more the fragrance retention effect of the washing composition increases. As shown in Comparative Example 1, when the addition amount of the fragrance retention particles in Comparative Example 1 is the same as that in Example 1, the fragrance retention effect of the washing composition in Comparative Example 1 becomes weak. This is because when the conventional manufacturing method is adopted, there is a risk that the fragrance of the fragrance retention particles is released in advance due to the rupture of the fragrance retention particles.

[0080] Table 4 Dyeing level

Table 4

[0081] As shown in Table 4, the dyeing level of the washing compositions of Examples 1 to 9 is related to the addition amount of the softener. The more the addition amount of the softener increases, the higher the dyeing level of the washing composition becomes, and the stronger the ability to prevent color mixing becomes. As shown in Comparative Example 1, when the addition amount of the softener in Comparative Example 1 is the same as that in Example 1, the dyeing level in Comparative Example 1 becomes weaker than that in Example 1. This is because there is a risk that the softener decreases when manufacturing the washing composition. The reason why the color mixing prevention ability of Comparative Example 3 is stronger than that of Example 1 is that the cationic modified starch may adsorb some dyes.

[0082] In addition, a tensile test is performed on the packaging materials manufactured in Examples 1 to 5 and Comparative Examples 2 to 3. The tensile test is carried out based on the method of GB / T 3923.1-1997, and the data of the obtained breaking force are compared (after cutting the packaging material into strips with a width of 5 cm and a length of 11 cm, both ends of the strip are fixed to a tensile device. Next, the packaging material is pulled at a constant speed until it breaks, and the maximum tensile force of the packaging material when it breaks is recorded. The unit of the maximum tensile force is N). The specific test results are as shown in Table 5.

[0083] Table 5 Breaking force of the packaging material

Table 5

[0084] As shown in Table 5, the breaking force of the packaging material is related to the addition amount and type of the first film-forming agent. The breaking force of the packaging materials manufactured in Examples 1 to 5 is all 10.91 N or more. Thereby, when packaging the functional component with the packaging material of the present invention, it can be ensured that the packaging material does not rupture. As shown in Comparative Example 3, when the first film-forming agent is not added to the packaging material, the maximum breaking force of the packaging material remains at 9.819 N. According to the test, when packaging the functional component with a packaging material having a breaking force less than 10 N, the packaging material is likely to rupture. Therefore, it is necessary to add a first film-forming agent with a large breaking force to the packaging material. Since polyvinyl alcohol cannot be easily decomposed, it is preferable to reduce the addition amount of the first film-forming agent as long as the demand for the breaking force of the packaging material can be satisfied.

[0085] As described above, the matters of the present invention have been detailed by way of the preferred embodiments of the present invention. However, since the preferred embodiments are merely illustrative of the present invention, the present invention is not limited only to the above embodiments. Those skilled in the art in this technical field can make design changes, improvements, etc. without departing from the technical matters and the gist of the invention. It is natural that even with such design changes, improvements, etc., they are included in the scope of the claims of the present invention.
