[0001] The invention relates to the technical field of washing products, and in particular provides a washing agent. Background Art

[0002] With the improvement of people's quality of life and the acceleration of work pace, cleaning work is gradually replaced by washing equipment. People are also more inclined to use easily soluble and efficient detergents.

[0003] However, due to different family education backgrounds and usage habits, users have different requirements for appearance indicators (such as the amount of foam) during the washing process. Some older people like washing methods with rich foam, while young people, who are generally more educated, prefer washing methods with less foam.

[0004] At present, the existing detergents cannot adjust the amount of foam during use. For those who prefer rich foam, they can only add more detergent to achieve a rich foam washing effect, but this will cause a waste of detergent. For those who prefer less foam washing, they can achieve the less foam washing effect by reducing the amount of detergent, but this will affect the cleaning power, resulting in a poor user experience. Summary of the invention

[0005] The present invention aims to solve the above technical problem at least to a certain extent, that is, to solve at least to a certain extent the problem that the existing detergents cannot adjust the amount of foam during use, resulting in a poor user experience.

[0006] In a first aspect, the present invention provides a detergent comprising a foam-type surfactant and a foam control agent, wherein the foam-type surfactant is capable of generating foam, and the foam control agent is capable of adjusting the amount of foam that can be generated by the foam-type surfactant according to the pH value of the detergent and / or the pH value of the detergent during use.

[0007] In a preferred technical solution of the above detergent, the mass ratio of the foam-type surfactant to the foam control agent is in the range of 2-6.

[0008] In the preferred technical scheme of the above-mentioned detergent, the detergent also includes alkali solution and deionized water, and the total weight proportions of the foam-type surfactant, the foam control agent, the alkali solution and the deionized water are 100 parts, wherein the weight proportions of each raw material are: 5-60 parts of foam-type surfactant; 1-15 parts of foam control agent; 0.1-15 parts of alkali solution; and the balance of deionized water.

[0009] In the preferred technical solution of the above detergent, the foam-type surfactant includes an anionic surfactant, and the anionic surfactant is one or a combination of any of sodium alkylbenzene sulfonate, olefin sulfonate, and fatty alcohol polyoxyethylene ether sulfate.

[0010] In the preferred technical solution of the above detergent, the foam-type surfactant also includes a nonionic surfactant, wherein the weight fraction ratio of the nonionic surfactant to the anionic surfactant is (0-30):(5-30).

[0011] In the preferred technical scheme of the above-mentioned detergent, the detergent also includes an auxiliary agent and a solvent, and the total weight parts of the foam-type surfactant, the foam control agent, the alkali solution, the deionized water, the auxiliary agent and the solvent are 100 parts, wherein the weight parts of each raw material are: 5-60 parts of foam-type surfactant; 1-15 parts of foam control agent; 0.1-15 parts of alkali solution; 0-15 parts of auxiliary agent; 0-15 parts of solvent; and the balance of deionized water.

[0012] In the preferred technical solution of the above detergent, the auxiliary agent is one or a combination of any of the following: a chelating agent, a complex enzyme, a flavor, a blue pigment, a defoaming agent, and a preservative.

[0013] In the preferred technical solution of the above detergent, the alkali solution is one of sodium hydroxide, ammonia water, ethanolamine, triethanolamine, sodium carbonate, potassium hydroxide or a combination of any two of them.

[0014] In the preferred technical solution of the above detergent, the foam control agent at least includes branched oil vinyl ether and amine ether.

[0015] In the preferred technical scheme of the above-mentioned detergent, the foam-type surfactant includes fatty alcohol polyoxyethylene ether, dodecylbenzene sulfonic acid, and fatty alcohol polyoxyethylene ether sodium sulfate, the foam control agent includes branched oil vinyl ether and amine ether, and the detergent includes the following components in parts by weight: 10-20 parts of fatty alcohol polyoxyethylene ether; 10-20 parts of dodecylbenzene sulfonic acid; 10-20 parts of fatty alcohol polyoxyethylene ether sodium sulfate; 5-15 parts of branched oil vinyl ether and amine ether; 0.5-2.5 parts of sodium citrate; 1-5 parts of dispersant; 1-5 parts of complex enzyme; 1-8 parts of liquid alkali; 0.8-2 parts of flavor; 0.01-0.5 parts of blue pigment; 0.01-0.5 parts of defoaming agent; 0.1-1 parts of preservative; 1-10 parts of propylene glycol; 1-10 parts of ethanol; and 15-50 parts of deionized water.

[0017] Furthermore, by reasonably controlling the mass ratio of the foam-type surfactant to the foam control agent, on the one hand, it can be avoided that the foam control agent is unable to increase the amount of foam generated by the foam-type surfactant due to the addition of too little foam control agent; on the other hand, it can be avoided that the addition of too little foam type surfactant leads to failure to generate enough foam; at the same time, it can also be avoided that the cleaning power of the detergent is affected due to the addition of too little foam type surfactant.

[0020] Figure 2 is a schematic diagram of the detergent of the present invention generating moderate foam during the washing process;

[0021] Figure 3 It is a schematic diagram that the detergent of the present invention generates a small amount of foam during the washing process. DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0023] The experimental methods in the following examples are conventional methods unless otherwise specified; the raw materials, reagents, etc. used in the following examples are commercially available products unless otherwise specified.

[0024] Based on the fact that the existing detergents mentioned in the background technology cannot adjust the amount of foam during use, people who prefer rich foam can only add more detergent to achieve a rich foam washing effect, but this will cause a waste of detergent. For people who prefer less foam washing, the less foam washing effect can be achieved by reducing the amount of detergent, but this will affect the cleaning power, resulting in a poor user experience. The present invention provides a detergent.

[0025] Specifically, the detergent of the present invention includes a foam-type surfactant and a foam control agent. The foam-type surfactant can generate foam, and the foam control agent can adjust the amount of foam that can be generated by the foam-type surfactant according to the pH value of the detergent and / or the pH value of the detergent during use.

[0026] Since the foam control agent can adjust the amount of foam that can be generated by the foam-type surfactant according to the pH value of the detergent and / or the pH value of the detergent during use, the amount of foam that can be generated by the foam-type surfactant changes with the change of the pH value of the detergent and / or the pH value of the detergent during use, thereby being able to adjust the amount of foam of the detergent during the washing process, achieving the adjustability of the amount of foam of the detergent during use, meeting the needs of different users for the amount of washing foam, and greatly improving the user experience.

[0027] It should be noted that the pH value of the detergent during use is the pH value of the washing solution during the washing process.

[0028] Exemplarily, a proper amount of detergent and water form a washing solution, and the foam control agent can adjust the amount of foam that can be generated by the foam-type surfactant according to the pH value of the washing solution.

[0029] Preferably, the mass ratio of the foam type surfactant to the foam control agent is 2-6.

[0030] By reasonably controlling the mass ratio of the foam-type surfactant to the foam control agent, on the one hand, it is possible to avoid the situation where the foam-type surfactant cannot produce the foam amount that can be produced due to too little addition of the foam control agent. The foam-type surfactant can be adjusted according to the pH value of the detergent and / or the pH value of the detergent during use. On the other hand, it is possible to avoid the situation where the foam-type surfactant cannot produce enough foam due to too little addition of the foam-type surfactant. At the same time, it is possible to avoid the situation where the detergent's cleaning power is affected due to too little addition of the foam-type surfactant, thereby enabling the detergent to achieve a better foam adjustment effect during use.

[0031] It should be noted that the present invention does not impose any limitation on the specific types of foam control. For example, the foam control agent may be a branched oil vinyl ether and an amine ether, or the foam control agent may be other types, as long as the amount of foam generated by the foam-type surfactant can be adjusted according to the pH value of the detergent or the pH value of the washing solution, etc. Such adjustment and change of the specific type of foam control agent does not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0032] Preferably, the foam control agent of the present invention is branched oil vinyl ether and amine ether.

[0033] Among them, branched oil vinyl ether and amine ether can be purchased from Guangzhou Qinxiang Chemical Co., Ltd., and the product name is branched oil vinyl ether and amine ether.

[0034] Specifically, branched oil vinyl ethers and amine ethers can inhibit the foam volume of foam-type surfactants to varying degrees, and the inhibitory effect becomes stronger as the pH value of the detergent decreases.

[0035] It should be noted that the present invention does not impose any limitation on the specific form of the detergent. For example, the detergent may be in a liquid state, and the detergent is directly dissolved in water to form a washing solution. Alternatively, the detergent may be in a solid state, and the solid detergent is dissolved in water to form a washing solution. Alternatively, the detergent may be in a powder state, and the powdered detergent is dissolved in water to form a washing solution, and so on. Such adjustments and changes to the specific form of the detergent do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0036] Preferably, the detergent of the present invention is in a liquid state.

[0037] It should be noted that the detergent of the present invention can be a laundry detergent for washing textiles and shoes, or a detergent for washing dishes and fruits, or a shampoo for washing hair, etc. Such adjustments and changes to the specific application direction of the detergent do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0038] The present invention will now be described in detail using laundry detergent as an example.

[0039] Preferably, the detergent of the present invention further comprises alkali solution and deionized water, and the total weight parts of the foam type surfactant, the foam control agent, the alkali solution and the deionized water is 100 parts, wherein the weight parts of each raw material are:

[0040] 5-60 parts of foam type surfactant;

[0041] 1-15 parts of foam control agent;

[0042] 0.1-15 parts of lye;

[0043] Deionized water balance.

[0044] By adding alkaline solution to the detergent, the pH value of the detergent can be adjusted, which helps to make the detergent into a detergent within a specific pH range according to the amount of foam required by the user, so that the amount of foam of the detergent meets the user's usage needs and further improves the user's usage experience.

[0045] Preferably, the pH value of the detergent of the present invention is 7.8 to 10.2.

[0046] Among them, when the pH value of the detergent is ≤8.5, the amount of foam generated by the detergent during the washing process is small;

[0047] When the pH value of the detergent is 8.5<9.5, the amount of foam produced by the detergent during washing is moderate;

[0048] When the pH value of the detergent is ≥9.5, the amount of foam generated by the detergent during the washing process is abundant.

[0049] That is to say, the pH value of the prepared detergent is different depending on the amount of alkali solution added, and the amount of foam generated by the detergent during use is different.

[0050] It should be noted that the present invention does not impose any limitation on the specific types of foam-type surfactants. For example, the foam-type surfactants may include only anionic surfactants, or the foam-type surfactants may also include a combination of anionic surfactants and non-ionic surfactants, etc. Such adjustments and changes to the specific types of foam-type surfactants do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0051] In a specific embodiment of the present invention, the foaming surfactant of the present invention includes an anionic surfactant, and the anionic surfactant is one or a combination of any of sodium alkylbenzene sulfonate, olefin sulfonate, and fatty alcohol polyoxyethylene ether sulfate.

[0052] In another specific embodiment of the present invention, the foam-type surfactant of the present invention includes anionic surfactant and nonionic surfactant, wherein the weight fraction ratio of the nonionic surfactant to the anionic surfactant is (0-30):(5-30).

[0053] It should be noted that the present invention does not impose any limitation on the specific types of anionic surfactants. For example, the anionic surfactants of the present invention can be one or a combination of any of sodium alkylbenzene sulfonate, olefin sulfonate, fatty alcohol polyoxyethylene ether sulfate, etc. Such adjustments and changes to the specific types of anionic surfactants do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0054] It should also be noted that the present invention does not impose any restrictions on the specific types of non-ionic surfactants. For example, the non-ionic surfactant of the present invention can be one or a combination of any of fatty alcohol polyoxyethylene ethers, alkylphenol polyoxyethylene ethers, fatty acid polyoxyethylene esters, polyoxyethylene alkylamines, polyoxyethylene alkylamides and polyethers.

[0055] Preferably, the detergent of the present invention further comprises an auxiliary agent and a solvent, and the total weight parts of the foam type surfactant, the foam control agent, the alkali solution, the deionized water, the auxiliary agent and the solvent are 100 parts, wherein the weight parts of each raw material are:

[0056] 5-60 parts of foam type surfactant;

[0058] 0.1-15 parts of lye;

[0059] Additives 0-15 parts;

[0060] Solvent 0-15 parts;

[0061] Deionized water balance.

[0062] It should be noted that the present invention does not impose any limitation on the specific type of alkali solution. For example, the alkali solution can be one of sodium hydroxide, ammonia water, ethanolamine, triethanolamine, sodium carbonate, potassium hydroxide, or any combination thereof. Such adjustment and change to the specific type of alkali solution does not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0063] Preferably, the alkali solution is sodium hydroxide, ethanolamine or triethanolamine.

[0064] It should be noted that the present invention does not impose any limitation on the specific types of auxiliary agents. For example, the auxiliary agents of the present invention may be one or a combination of any of enzyme preparations, chelating agents, dispersants, defoaming agents, preservatives, flavoring agents, etc. Such adjustments and changes to the specific types of auxiliary agents do not deviate from the principles and scope of the present invention and should be included in the protection scope of the present invention.

[0065] Exemplarily, the auxiliary agents include complex enzymes, sodium citrate, dispersants, flavors, blue pigments, defoamers, and preservatives.

[0066] It should be noted that the present invention does not impose any restrictions on the specific types of solvents. For example, the solvent can be a combination of one or more alcohol substances such as polyols, low-carbon alcohols, high-carbon alcohols, etc. Such adjustments and changes to the specific types of solvents do not deviate from the principles and scope of the present invention and should be included in the protection scope of the present invention.

[0293] Test example:

[0294] Take an appropriate amount of the detergent of the embodiment and the comparative example and add it to the washing machine (the amount of detergent added in each embodiment and the comparative example is shown in Table 1), take 3 kg of polyester-cotton (4:9) mixed fabric as the load, and make the load into contaminated cloth according to the European standard as the washing object, and select the 10 kg machine smart wash default program for washing, wherein the washing temperature is 30 ° C, the speed is 800 rpm, the main wash is 1 time, the rinse is 2 times, and the total washing time is 62 min.

[0295] Observe the maximum amount of foam produced during the main wash and follow Figures 1 to 3 To rate the state of foam produced during washing.

[0296] Specifically, Figure 1 As shown, the height of the highest foam volume is greater than 2 / 3 of the entire barrel window, and the foam volume is rated as "rich";

[0297] like Figure 2 As shown, the highest foam volume is between 1 / 3 and 2 / 3 of the entire barrel window, and the foam volume is rated as "moderate";

[0298] like Figure 3 As shown, the height of the highest foam amount is less than 1 / 3 of the entire barrel window, and the foam amount is rated as "small amount".

[0299] Table 1: Test results of embodiments and comparative examples

[0300] From the test results in Table 1, we can see that:

[0301] 1. The amount of foam produced by detergent during the washing process changes with the pH value of the detergent.

[0302] (1) According to the test results of Examples 1 to 3, for a detergent with a 3x concentrated formula (total active substance of 45%), as the pH value of the detergent changes, the amount of foam generated during the washing process also changes, that is, as the pH value of the detergent decreases, the amount of foam generated during the washing process gradually decreases.

[0303] (2) According to the test results of Examples 4 to 7, for detergents with an ordinary single formula (total active substance is 15%), as the pH value of the detergent changes, the amount of foam generated during the washing process also changes, that is, as the pH value of the detergent decreases, the amount of foam generated during the washing process gradually decreases.

[0304] (3) According to the test results of Examples 10 and 11, for the detergent with a 2x concentrated formula (total active substance is 30%), as the pH value of the detergent changes, the amount of foam generated during the washing process also changes, that is, as the pH value of the detergent decreases, the amount of foam generated during the washing process gradually decreases.

[0305] In summary, for single-formula detergents, double-concentrated formula detergents, and triple-formula detergents, the amount of foam generated by the detergent during the washing process can change with the change of the pH value of the detergent.

[0306] And because the amount of water used in each embodiment and comparative example during the test process is the same, the pH value of the detergent in each embodiment and comparative example also determines the pH value of the detergent during the washing process, that is, when the pH value of the detergent is relatively high, the pH value of the detergent during the washing process will also be relatively high, and the amount of foam generated during the washing process will also be relatively abundant. Similarly, when the pH value of the detergent is relatively low, the pH value of the detergent during the washing process will also be relatively low, and the amount of foam generated during the washing process will also be relatively small. When the pH value of the detergent is relatively moderate, the pH value of the detergent during the washing process will also be moderate, and the amount of foam generated during the washing process will also be moderate.

[0307] 2. Anionic surfactants and foam control agents are key factors that cause the amount of foam generated by detergents during the washing process to change with the pH value of the detergent.

[0308] (1) Comparing Examples 1 to 3 with Comparative Examples 1 to 3, if the detergent contains an anionic surfactant and a foam control agent, the amount of foam generated during the washing process changes with the change of the pH value. If the detergent does not contain an anionic surfactant, the amount of foam generated during the washing process does not change with the change of the pH value. It can be seen that the anionic surfactant is the key factor that causes the amount of foam generated by the detergent during the washing process to change with the change of the pH value of the detergent.

[0309] (2) Comparing Examples 4 to 7 with Comparative Examples 4 to 7, if the detergent contains anionic surfactants, nonionic surfactants and foam control agents, the amount of foam generated during the washing process changes with the change of pH value. If the detergent does not contain the foam control agent, the amount of foam generated during the washing process does not change with the change of pH value. It can be seen that the foam control agent is the key factor that causes the amount of foam generated by the detergent during the washing process to change with the change of pH value of the detergent.

[0310] (3) Comparing Examples 1 to 3 with Examples 4 to 7, if the detergent contains a solvent, the amount of foam generated during the washing process varies with the pH value of the detergent. If the detergent does not contain a solvent, the amount of foam generated during the washing process also varies with the pH value of the detergent. It can be seen that the solvent is not the key factor that causes the amount of foam generated during the washing process to vary with the pH value of the detergent.

[0311] (4) Comparing Examples 1 to 3 with Examples 8 to 9, if the detergent contains a nonionic surfactant, the amount of foam generated during the washing process varies with the pH value of the detergent. If the detergent does not contain a nonionic surfactant, the amount of foam generated during the washing process also varies with the pH value of the detergent. It can be seen that the nonionic surfactant is not the key factor that causes the amount of foam generated by the detergent during the washing process to vary with the pH value of the detergent.

[0312] (5) Comparing Examples 10 to 11 with Examples 12 to 13, if the detergent contains additives, the amount of foam generated during the washing process changes with the pH value of the detergent. If the detergent does not contain additives, the amount of foam generated during the washing process also changes with the pH value of the detergent. It can be seen that additives are not the key factor that causes the amount of foam generated by the detergent during the washing process to change with the pH value of the detergent.

[0313] In summary, anionic surfactants and foam control agents are the key factors that cause the amount of foam generated by detergents during the washing process to change with the change of the pH value of the detergent, and non-ionic surfactants, solvents and additives are not the key factors that cause the amount of foam generated by detergents during the washing process to change with the change of the pH value of the detergent.

[0314] Therefore, by applying anionic surfactants and foam control agents together in detergents, the amount of foam generated during the washing process can be adjusted by adjusting the pH value of the washing solution during use of the detergent to meet the needs of different users.

[0315] The influence of the pH value of the detergent of the present invention on the amount of foam generated during use of the detergent is described below in conjunction with the following situations.

[0316] In a preferred embodiment of the present invention, the detergent includes fatty alcohol polyoxyethylene ether, dodecylbenzene sulfonic acid, fatty alcohol polyoxyethylene ether sodium sulfate, branched oil vinyl ether and amine ether, sodium citrate, dispersant, complex enzyme, liquid alkali, flavor, blue pigment, and deionized water. The total weight of each raw material is 100 parts, and the weight of each raw material is as follows: 10-20 parts of fatty alcohol polyoxyethylene ether; 10-20 parts of dodecylbenzene sulfonic acid; 10-20 parts of fatty alcohol polyoxyethylene ether sodium sulfate; 5-15 parts of branched oil vinyl ether and amine ether; 0.5-2.5 parts of sodium citrate; 1-5 parts of dispersant; 1-5 parts of complex enzyme; 1-8 parts of liquid alkali; 0.8-2 parts of flavor; 0.01-0.5 parts of blue pigment, 0.01-0.5 parts of defoaming agent; 0.1-1 parts of preservative; 1-10 parts of propylene glycol; 1-10 parts of ethanol; 15-50 parts of deionized water.

[0317] Scenario 1:

[0318] 10 parts of fatty alcohol polyoxyethylene ether, 12 parts of dodecylbenzene sulfonic acid, 15 parts of fatty alcohol polyoxyethylene ether sodium sulfate, 10 parts of branched oil vinyl ether and amine ether, 1 part of sodium citrate, 4 parts of dispersant, 2 parts of complex enzyme, 8 parts of liquid alkali, 1.5 parts of flavor, 0.05 parts of blue pigment, 0.05 parts of defoaming agent, 0.5 parts of preservative, 3 parts of propylene glycol, 7 parts of ethanol, 25.9 parts of deionized water, pH value (1% aqueous solution) equal to 10.0.

[0319] After testing, the amount of foam generated by the detergent during use is Figure 1 Similarly, when the pH value of the detergent is 10.0, the detergent can produce abundant foam during use.

[0320] Scenario 2:

[0321] 10 parts of fatty alcohol polyoxyethylene ether, 12 parts of dodecylbenzene sulfonic acid, 15 parts of fatty alcohol polyoxyethylene ether sodium sulfate, 10 parts of branched oil vinyl ether and amine ether, 1 part of sodium citrate, 4 parts of dispersant, 2 parts of complex enzyme, 6 parts of liquid alkali, 1.5 parts of flavor, 0.05 parts of blue pigment, 0.05 parts of defoaming agent, 0.5 parts of preservative, 3 parts of propylene glycol, 7 parts of ethanol, 27.9 parts of deionized water, pH value (1% aqueous solution) equal to 9.0.

[0322] After testing, the amount of foam generated by the detergent during use is Figure 2 Similarly, that is, when the pH value of the detergent is 9.0, the detergent can produce moderate foam during use.

[0323] Scenario 3:

[0324] 10 parts of fatty alcohol polyoxyethylene ether, 12 parts of dodecylbenzene sulfonic acid, 15 parts of fatty alcohol polyoxyethylene ether sodium sulfate, 10 parts of branched oil vinyl ether and amine ether, 1 part of sodium citrate, 4 parts of dispersant, 2 parts of complex enzyme, 4 parts of liquid alkali, 1.5 parts of flavor, 0.05 parts of blue pigment, 0.05 parts of defoaming agent, 0.5 parts of preservative, 3 parts of propylene glycol, 7 parts of ethanol, 29.9 parts of deionized water, pH value (1% aqueous solution) equals 8.0.

[0325] After testing, the amount of foam generated by the detergent during use is Figure 3 Similarly, that is, when the pH value of the detergent is 8.0, the detergent can generate a small amount of foam during use.

[0326] To sum up, the amount of foam generated by detergents during use varies with the pH value of the detergent, and as the pH value of the detergent decreases, the amount of foam that can be generated by the detergent during use gradually decreases. Therefore, by preparing detergents with different pH values, detergents that generate different amounts of foam during use can be obtained. At the same time, the amount of foam generated during the washing process can also be adjusted by changing the pH value of the washing solution (the solution containing the detergent).
