Description

Technical Field

[0001] The invention relates to the technical field of daily chemical products, and in particular to a hand cleaning liquid and a preparation method and application thereof. Background Art

[0002] As a very common washing product in family life, dishwashing liquid is a product commonly used in families to clean dirt and oil. Since dishwashing liquid has close contact with food and human skin, it needs to be as gentle as possible on human skin and also requires it to have good decontamination ability. At present, the main component of dishwashing liquid is surfactant. The surfactant and preservative used in existing dishwashing liquid are generally synthetic chemicals. The advantages of this type of surfactant are strong detergency, good solubility and low cost. However, if used for a long time, the trace amount of dishwashing liquid components remaining on the tableware will pose a potential threat to the human body, and will have a negative impact on the skin of the dishwashing liquid user, easily making the skin rough and yellow. Especially for users with sensitive skin, long-term use of this type of dishwashing liquid will cause dryness, peeling, roughness and easy blisters on the hands. Currently, most commercially available dishwashing liquids use chemical surfactants such as sodium dodecylbenzene sulfonate and fatty alcohol polyoxyethylene ether sulfate as the main cleaning ingredients. Although their washing and decontamination ability is relatively ideal, long-term use is easy to cause damage to human skin.

[0003] Therefore, it is urgent to develop a detergent with low irritation to people's skin. Summary of the invention

[0004] The present invention aims to solve the above technical problems existing in the prior art. To this end, the present invention proposes a hand-protecting detergent and its preparation method and application, wherein the formula system of the detergent is low-irritating, ensuring the decontamination effect of the detergent while achieving the effect of protecting the hands.

[0005] The invention also provides a preparation method of the hand-protecting detergent.

[0006] The invention also proposes the application of the detergent in the field of daily chemical products.

[0007] According to one aspect of the present invention, a hand cleaning liquid is provided, the components of which include sodium fatty acid methyl ester sulfonate, sodium linear alkyl benzene sulfonate and sodium fatty alcohol polyoxyethylene ether sulfate.

[0008] According to the embodiments of the first aspect of the present invention, there are at least the following beneficial effects:

[0009] When sodium fatty acid methyl ester sulfonate (MES) is compounded with linear alkylbenzene sulfonate (LAS) and sodium fatty alcohol polyoxyethylene ether sulfate (AES) in the present invention, MES can significantly reduce the irritation of LAS and AES, and the system presents low irritation. At the same time, the detergency of the formula when MES, AES and LAS are compounded has a good improvement effect. Fatty acid methyl ester sulfonate (MES), also known as α-sulfo fatty acid methyl ester salt, has excellent calcium soap dispersibility, low irritation and good biodegradability. The structure of the fatty acid methyl ester part in MES is similar to the structure of fatty acid glyceride in the skin, and the properties are similar, and it has good compatibility with the skin. When MES contacts the skin, it forms a layer of oil film on the skin surface to reduce the water loss of the skin. Therefore, MES is mild to the skin.

[0010] In some embodiments of the present invention, the components of the hand detergent include: sodium fatty acid methyl ester sulfonate, sodium linear alkyl benzene sulfonate and sodium fatty alcohol polyoxyethylene ether sulfate in a weight ratio of 7.2-27:0.3-5:2-12.85.

[0011] After compounding the functional surfactant in the formula of MES, LAS and AES in the above ratio, the irritation of the system can be significantly reduced and the detergency can be improved.

[0012] In some embodiments of the present invention, the components of the hand detergent further include: a copolymer of an acrylic polymer grafted with a polyether compound.

[0013] In some embodiments of the present invention, the copolymer of the acrylic polymer grafted with the polyether compound comprises the following structure of Formula I or Formula II:

[0014]

[0015] The R1 is selected from one of the following structures:

[0016]

[0017] Wherein, a is 0 to 25, b is 0 to 8, z is 0 to 25, and y: (x+z) is 0.1 to 0.4, n is a positive integer of 2 to 14, and m is a positive integer of 2 to 12.

[0018] Functional surfactants are copolymers of acrylic polymers grafted with polyether compounds, which are new functional polymer materials with excellent water absorption and adhesiveness. Its mechanism of action is that the hydrophilic group of the functional surfactant cross-links with the surfactant components in the system to form a three-dimensional structure, which increases the resistance of the components when moving in water and increases the van der Waals force between particles, reducing the distance between particles, increasing the viscosity of the system and having a thickening effect. In addition, when the system comes into contact with the skin, the functional surfactant can synergize with fatty acid methyl ester sulfonate, and the lipophilic group of the functional surfactant assists the fatty acid methyl ester part of the fatty acid methyl ester sulfonate to form an oil film on the skin surface, reducing the water loss of the skin. At the same time, the hydrophilic group of the functional surfactant can form hydrogen bonds with the water molecules around the skin, absorb the water on the skin surface, and form a protective film, further reducing the loss of water from the skin, locking in water, and helping the skin stay hydrated and soft.

[0019] In some embodiments of the present invention, the components of the hand detergent include, by weight: 5 to 30 parts of sodium fatty acid methyl ester sulfonate, 0.3 to 10 parts of sodium linear alkyl benzene sulfonate and 2 to 15 parts of sodium fatty alcohol polyoxyethylene ether sulfate.

[0020] After the MES, LAS and AES in the above weight proportions are compounded with a functional surfactant, the functional surfactant further reduces the irritation of the system and significantly improves the skin feel after washing.

[0021] In some embodiments of the present invention, the components of the hand detergent further include: an amphoteric surfactant, and the amphoteric surfactant includes: at least one of an amino acid surfactant, a betaine surfactant, an imidazoline surfactant and an amine oxide surfactant.

[0022] In some embodiments of the present invention, the amphoteric surfactant is cocamidopropyl betaine.

[0023] In some embodiments of the present invention, the components of the hand detergent further include: auxiliary agents, and the auxiliary agents include chelating agents, fragrances, preservatives and inorganic salts.

[0024] In some embodiments of the present invention, the components of the hand detergent include, by weight: 5 to 30 parts of sodium fatty acid methyl ester sulfonate, 0.3 to 5 parts of sodium linear alkyl benzene sulfonate and 2 to 15 parts of sodium fatty alcohol polyoxyethylene ether sulfate, 0 to 2 parts of functional surfactants, 0 to 5 parts of amphoteric surfactants, 0 to 0.5 parts of chelating agents, 0 to 0.5 parts of flavors, 0 to 1 parts of preservatives, and 0 to 1.5 parts of inorganic salts.

[0025] The present invention controls the compounding ratio of linear alkylbenzene sulfonate (LAS), sodium fatty alcohol polyoxyethylene ether sulfate (AES), sodium fatty acid methyl ester sulfonate (MES), copolymer of acrylic polymer grafted polyether compound and other components, so that the obtained composition can maintain uniformity and transparency at low temperature, and the cost is low. The irritation is low, which is much lower than the irritation of traditional dishwashing liquid on the market, and the decontamination performance is higher than the national standard dishwashing detergent and is not worse than the traditional dishwashing detergent on the market. At the same time, it has the feasibility of large-scale production.

[0026] In some embodiments of the present invention, the components of the hand detergent also include: water.

[0027] In some embodiments of the present invention, the chelating agent includes at least one of ethylenediaminetetraacetate, diethyltriaminepentaacetate, methylglycine diacetate, glutamic acid diacetate and sodium citrate dihydrate.

[0028] In some embodiments of the invention, the chelating agent comprises glutamate diacetate.

[0029] In some embodiments of the present invention, the flavor includes herbal flavor, fruit flavor, and floral flavor.

[0030] In some embodiments of the present invention, the herbal aroma includes mint, spearmint, rosemary, thyme, sage, pine and spruce.

[0031] In some embodiments of the present invention, the fruit flavor comprises apple, almond, grape, cherry, pineapple, pear, peach, mango, orange, strawberry, blueberry and citrus.

[0032] In some embodiments of the present invention, the floral fragrance includes rose, lavender, carnation, vanilla, gardenia, hawthorn, chypre, honeysuckle, cyclamen, hyacinth, bracken, clove, jasmine, lily, mimosa, magnolia, orchid, daffodil, orange blossom, licorice, mignonette, clover, violet, sweet pea and wallflower.

[0033] In some embodiments of the present invention, the preservative includes at least one of methylisothiazolinone, phenoxyethanol and methylchloroisothiazolinone.

[0034] In some embodiments of the present invention, the inorganic salt comprises at least one of a sodium salt and a magnesium salt.

[0035] In some embodiments of the invention, the sodium salt comprises sodium chloride.

[0036] The second aspect of the present invention provides a method for preparing a hand detergent, comprising: mixing the components of the hand detergent.

[0037] The third aspect of the present invention proposes the application of the above-mentioned hand detergent in the field of daily chemical products. BRIEF DESCRIPTION OF THE DRAWINGS

[0072]

[0073] Test Example 1

[0074] The performance tests of the hand cleaning liquid compositions of the above embodiments and comparative examples are carried out, and the results are shown in Tables 2, 3 and Figures 1 to 12 The irritation results are shown in Table 4. The specific operation methods for evaluating the relevant tests are as follows:

[0075] 1) Irritation test

[0076] Chicken embryo chorioallantoic membrane test: Take a number of SPF chicken embryos incubated to nine days old, and make a group of 6 chicken embryos. Each sample corresponds to a group of tests. Dilute the sample with distilled water to a concentration of 0.5%, take 0.3ml of the test sample and drop it on the surface of the chicken embryo CAM membrane, observe the CAM reaction, and record the time of each toxic effect within 5 minutes, and take photos of the test results and save them.

[0088] Table 4 Evaluation of irritation results

[0089] End point scoring Irritation classification IS<1 Non-irritating 1≤IS<5 Mild irritation 5≤IS<9 Moderate irritation IS ≥ 10 Strong irritation

[0090] From the irritation results of the embodiments and comparative examples in Table 2, it can be seen that the irritation results of the embodiments are lower than those of the comparative examples, the irritation of the embodiments is in the mild irritation range, and the embodiments are feasible.

[0091] From the results in Table 3 and Table 2, it can be seen that the commercially available dishwashing liquids claiming to have hand protection effects are all highly irritating, with irritation scores greater than 10, while the irritation of the embodiments is all low and mild to the skin, indicating that the embodiments are feasible.

[0092] The formula of the embodiment is relatively mild. Compared with comparative example 1, the irritation of LAS and AES can be significantly reduced by compounding MES in the embodiment, and the irritation of the system is significantly improved.

[0093] From the irritation results of Examples 1-3, it can be seen that as the MES content decreases and the AES content increases, the irritation of the system increases slightly, but remains within the range of mild irritation. It can be seen that when the MES in the formula is within a certain ratio, it also has a good stabilizing effect on the irritation of the system.

[0094] From the comparison of the irritation results of the embodiment and comparative examples 4 and 5, it can be seen that when MES, AES, and LAS are compounded within the ratio specified in the present invention, the irritation of the system is maintained in the range of mild irritation. When the ratio is not in the ratio specified in the present invention, the irritation of the system increases significantly. At this time, the addition of amphoteric surfactants and AG-U30 has no significant change in the decrease of irritation, and the system is in a state of medium irritation or close to strong irritation. It can be obtained that MES, AES, and LAS need to be compounded within the ratio specified in the present invention to maintain the effect of mild irritation.

[0095] The irritation of the embodiment is compared with that of comparative examples 2 and 3. It can be obtained that when MES, AES and LAS are compounded within the ratio specified in the present invention and supplemented with the functional surfactant AG-U30, the irritation of the system can be lower than the irritation of the formula system with the addition of nonionic surfactants, fat-filling agents and special additives of moisturizing agents. The embodiment has obvious economic advantages over comparative examples 2 and 3. The formula system with the commonly used surfactant LAS, AES and green anionic surfactant MES compounded or supplemented with the functional surfactant AG-U30 is compared with the formula system with the addition of a variety of fat-filling agents and special additives of moisturizing agents. The formula economy has a high cost performance, and the production process is simple and the feasibility is strong.

[0096] It can be seen from Examples 4, 5, 6 and Comparative Example 4 that when AG-U30 is compounded in the system, the irritation of the system decreases, and as the content of AG-U30 increases, the irritation of the system decreases accordingly.

[0097] Test Example 2

[0098] This test example uses the A.2 foam position method of the detergency test of Appendix A of GB 9985 2022 hand-washing dishwashing detergent to evaluate the detergency. The results are shown in Tables 5 and 6:

[0099] Table 5 Detergent results of hand detergent examples

[0100]

[0101] Table 6 Detergent performance results of commercially available detergents

[0102]

[0103]

[0104] From the results in Table 5, it can be seen that the detergency of the embodiments all meets the standard, and the detergency of the embodiments is substantially better than that of the standard detergent.

[0105] Combining the detergency results in Table 5 and Table 6, it can be seen that the detergency of the embodiment is equivalent to or better than that of commercially available detergents. The detergency of the embodiment meets the basic market demand and is feasible.

[0106] From the detergency results of Examples 1, 2, and 3, it can be seen that within a certain range, as the proportion of MES in the formula decreases and the proportion of AES increases, the detergency of the formula increases accordingly, which shows that AES has a good effect on improving the detergency of the formula.

[0107] From the detergency results of Examples 5 and 6 and Comparative Examples 4 and 5, it can be seen that as the proportion of MES in the formula decreases and the proportion of AES and LAS increases, the detergency of the formula increases accordingly. It can be seen that AES and LAS have a good effect on improving the detergency of the formula.

[0108] From the comparison of the detergency results of the embodiment and comparative examples 4 and 5, it can be seen that when MES, AES and LAS are compounded within the ratio specified in the present invention, the detergency can be guaranteed while the irritation of the system is maintained within the range of light irritation. For comparative examples 4 and 5, when LAS exceeds the ratio specified in the present invention, the detergency is improved to a certain extent, but the system is in a state of medium irritation or close to strong irritation. It can be seen that MES, AES and LAS need to be compounded within the ratio specified in the invention to have both detergency and low irritation effects.

[0109] From the detergency results of Examples 4, 5, and 6, it can be seen that the detergency of the formula remains unchanged with the addition of the functional surfactant AG-U30. It can be seen that the effect of AG-U30 on the detergency of the formula is comparable to that of the other surfactants in the formula.

[0110] From the detergency results of Comparative Examples 4 and 5, it can be seen that when a small amount of AG-U30 and amphoteric surfactants are compounded in the formula, the detergency of the formula is equivalent, and the contribution of AG-U30 and amphoteric surfactants to detergency is basically the same.

[0111] Test Example 3

[0112] In this test example, 30 volunteers were recruited to test the hand feel of the samples prepared in the embodiments and comparative examples after washing. The volunteers conducted a one-month trial inspection on the samples prepared in the embodiments and comparative examples, and scored the hand feel of the samples after washing in the range of 1-10. The higher the score, the better the hand feel after washing, and vice versa. The test standards are shown in Table 8, and the test results are shown in Table 7.

[0113] Table 7 Hand feel scoring results of hand detergent embodiments

[0114]

[0115] Table 8 Rating standard for hand feel after washing with hand detergent

[0116]

[0117]

[0118] From the hand feel scoring results in Table 7, it can be seen that the hand feel of the embodiments after washing is generally better than that of the comparative examples after washing. The hand feel of the embodiments after washing is better, and the embodiments are feasible.

[0119] The hand feel of the embodiment is better. Compared with comparative example 1, the irritation of LAS and AES can be significantly reduced by compounding MES in the embodiment, and the hand feel after washing is significantly improved.

[0120] From the hand feeling scoring results of Examples 1, 2, and 3, it can be seen that as the MES content in the system decreases and the AES content increases, the hand feeling after washing becomes worse, and the comfort of the skin after washing gradually decreases. This is because the structure of the fatty acid methyl ester part in MES is similar to the structure of fatty acid glyceride in the skin. When MES contacts the skin, it can form an oil film on the skin surface to reduce the water loss of the skin. Therefore, in the system of the present invention, the higher the MES content of the sample, the milder it is to the skin and the more comfortable the hand feeling is.

[0121] From the comparison of the hand feeling scores of the embodiment and comparative examples 4 and 5, it can be seen that when MES, AES and LAS are compounded within the ratio specified in the present invention, the detergency and irritation of the system can be maintained within the range of light irritation, and a relatively good hand feeling performance can be achieved. When LAS exceeds the ratio specified in the present invention, the detergency is improved to a certain extent, but the system is in a state of medium irritation or close to strong irritation.

[0122] Compared with the hand feeling after washing of comparative examples 2 and 3, the hand feeling after washing of the embodiment is better than that of comparative examples 2 and 3. It can be obtained that the hand feeling after washing of the system of MES is better than that of the formula system of special additives of adding nonionic surfactants, fat enriching agents and moisturizing agents by compounding with AES and LAS in a certain proportion or supplemented with functional surfactant AG-U30. The embodiment has obvious economic advantages over comparative examples 2 and 3. The formula system of compounding with commonly used surfactants LAS, AES and green anionic surfactant MES and adding a variety of fat enriching agents and moisturizing agents has a high cost performance of the formula economy, and the production process is simple and the feasibility is strong.

[0123] From the hand feel scoring results of Examples 4, 5, 6 and Comparative Examples 4 and 5, it can be seen that when AG-U30 is compounded in the system, the improvement effect on the hand feel after washing is more obvious, and as the content of AG-U30 increases, the comfort of the hand feel after washing increases accordingly. This is because AG-U30 can work synergistically with MES, and the lipophilic group of AG-U30 assists the fatty acid methyl ester part of MES to form an oil film on the skin surface, reducing the water loss of the skin. At the same time, the hydrophilic group of AG-U30 can form hydrogen bonds with the water molecules around the skin, forming another protective film on the skin, further reducing the loss of skin moisture, locking in moisture, and helping the skin stay hydrated and soft.
