[0002] Currently, issues related to the elderly have increasingly received extensive attention from all sectors of society. Among them, the phenomenon of aging odor (also known as "old people's smell") has gradually emerged and become one of the problems that cannot be ignored. Compared with other age groups, the elderly have relatively more leisure time, so social interaction occupies an important position in the lives of the elderly. However, aging odor, as a relatively common and easily detectable odor among the middle-aged and elderly groups, has brought many obstacles to their social lives. Aging odor not only causes psychological burdens on the elderly in interpersonal communication, reduces their quality of life, but also may lead to negative self-perception of their own images by the elderly, believing that they have lost their previous charm and value, thereby triggering negative emotions and affecting physical and mental health.

[0003] In the related art, under traditional washing conditions, it is difficult for detergents to thoroughly clean the odors attached to the clothes of the elderly.

No distinction is made between "aging", "accelerated aging", "aging treatment", and "accelerated aging treatment". No distinction is made between "2-nonenal" and "nonenal".

[0085] The term "fabric odor" involved in this application refers to the odor of aging. In the present invention, no distinction is made between "odor of aging", "old person smell", and "fabric odor".

[0086] The term "odor of aging" involved in this application refers to the general term for the odor produced by the oxidative decomposition of unsaturated fatty acids secreted by the human body or by the decomposition of skin resident bacteria. 2-Nonenal is one of the main components of this odor. In this application, 2-nonenal is used as a representative substance of the odor of aging, and the ability to remove 2-nonenal is used as a quantitative characterization of the ability to remove the odor of aging.

[0087] It should be noted that the "washing product" of this application is obtained by encapsulating the washing liquid with a water-soluble film. The volume of the encapsulated washing liquid is 5 mL to 35 mL. The term "outer membrane" in this application refers to the side of the water-soluble film that is exposed to the air in the detergent composition encapsulated by the water-soluble film. The term "inner membrane" refers to the side of the water-soluble film that is in direct contact with the liquid detergent composition in the detergent composition encapsulated by the water-soluble film.

[0088] The "washing liquid" of this application covers the following forms, in which the solid components are present in liquid compositions such as dispersions, gels, slurries, etc. The washing product also includes capsule-type detergents prepared using the washing liquid of this application.

[0089] The term "washing liquid" refers to any fabric detergent composition that includes a liquid capable of wetting and treating fabrics, and the ways of wetting and treating fabrics include pre-coating with the undiluted composition, hand-washing after dilution with tap water, machine-washing with a washing machine, etc. A large number of literature studies have shown that aging odor is closely related to unsaturated aldehydes such as octenal and nonenal. The main mechanism of its generation is as follows: The content of 9-hexadecenoic acid (palmitoleic acid) in the sebum secretions of middle-aged and elderly people shows an upward trend with age. This unsaturated fatty acid will undergo oxidative decomposition through lipid peroxides or decomposition reactions under the action of skin resident bacteria, and finally generate 2-nonenal with an unpleasant odor.

[0090] To effectively address the problem of aging odor, a variety of solutions have emerged in the current related technologies. For example, using a fragrance composition to mask the body odor of the elderly. However, this method only superficially masks the odor and fails to touch the root of the problem, and cannot fundamentally eliminate the "aging odor". Or using butylene glycol, oolong tea extract and sweet tea extract as aging odor deodorants. Although it has a certain deodorizing effect, the required concentration for the effect is quite high. For example, the concentration of 1,3-butylene glycol solution is as high as 50%, which may be restricted in practical applications. Or using arginine aspartate to remove 2-nonenal and then inhibit the odor of the elderly. However, the action time of this method is relatively long, up to 20 hours, and it is difficult to meet people's needs for convenient and efficient problem-solving. Moreover, most of the above methods are applied as skin external components in the cosmetics field, and a relatively high concentration or a long action time is required to achieve a better removal effect.

[0091] Under normal washing conditions, it is difficult for detergents to completely remove the odor attached to the clothes of the elderly, which undoubtedly brings new challenges to solving the problem of aging odor.

[0092] The water-soluble film-encapsulated liquid detergent composition is an innovative laundry product. It encapsulates a certain volume of detergent with a water-soluble film. It not only looks like beads, small, delicate, fashionable and beautiful, but also is extremely convenient to use. There is no need to measure laboriously. One can wash a bucket of clothes. It is an ideal choice for modern people who pursue a convenient and fashionable life. However, it also has problems with the interaction between the water-soluble film and the content, such as possible color change affecting the aesthetic degree; or soft collapse phenomenon, where the product loses its proper shape and integrity before use; in severe cases, it may even cause the content to precipitate, which not only affects the cleaning effect of the product, but also may cause pollution to other items during storage, bringing inconvenience and trouble to users.

[0093] How to provide a water-soluble film-encapsulated liquid detergent that can effectively remove fabric odors and has excellent stability is an urgent problem to be solved at present. Based on the above problems, this application will include a first component with a compound of a specific structure and a second component containing at least one of sulfite, pyrosulfite, and bisulfite, which are used together as a composition for removing aging odor, and can synergistically enhance the effect to effectively remove the aging odor of the clothes of the elderly.

[0094] One or more embodiments of this application provide a composition for removing aging odor, including a first component and a second component, and the mass ratio of the first component to the second component is 3:1 to 12:1; the first component has the structure shown in the following general formula (I):

[0095]

[0096] Among them, R1 is selected from one of C6-C12 alkyl groups;

[0097] The second component includes one or more of sulfite, pyrosulfite, and bisulfite.

[0098] It should be noted that in this application, "the first component", "the second component", etc. are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or quantity, nor can it be understood as implicitly indicating the importance or quantity of the indicated technical features. Moreover, "the first", "the second", etc. only serve the purpose of non-exhaustive enumeration and description, and it should be understood that they do not constitute a closed limitation on the quantity.

[0099] As an example, the mass ratio of the first component to the second component of 3:1 to 12:1 can be, but is not limited to, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, 10:1, 11:1, 12:1 or the range between any two of the above mass ratios, etc. When the mass ratio of the first component to the second component is within the above range, the water-soluble film-encapsulated liquid detergent composition not only has a good effect of removing the aging odor of the clothes of the elderly, but also has good stability at the same time, that is, after the detergent composition undergoes aging treatment, its content color change value, film integrity, film appearance change degree, content integrity, odor stability, and dissolution stability are also good.

[0100] It can be understood that in the composition for removing aging odor provided by this application, the primary amine group in the first component can react with the aldehyde group to form a Schiff base reaction, so as to effectively eliminate 2-nonenal, the main source substance of aging odor; the sulfite, pyrosulfite, and / or bisulfite in the second component can react with the aldehyde group in an oxidation-reduction reaction, so as to effectively remove 2-nonenal; by using the first component and the second component together, the effect can be synergistically enhanced to achieve an excellent 2-nonenal removal effect.

[0101] In some alternative embodiments, the first component is selected from one or more of n-hexyldipropylenetriamine, n-heptyldipropylenetriamine, isoheptyldipropylenetriamine, neoheptyldipropylenetriamine, n-octyldipropylenetriamine, iso-octyldipropylenetriamine, sec-octyldipropylenetriamine, tert-octyldipropylenetriamine, n-nonyldipropylenetriamine, n-decyldipropylenetriamine, n-undecyldipropylenetriamine, and n-dodecyldipropylenetriamine.

[0102] In some exemplary embodiments, the second component includes one or more of sodium sulfite, sodium bisulfite, and sodium metabisulfite.

[0103] One or more embodiments of the present application provide an application of the above-mentioned composition for removing aged odor in the preparation of a washing product for removing aged odor.

[0104] One or more embodiments of the present application provide a washing product for removing aged odor, the washing product includes a water-soluble film and a washing liquid encapsulated in the water-soluble film, the washing liquid includes a first component and a second component, and the mass ratio of the first component to the second component is 3:1 to 12:1; the first component has a structure shown in the following general formula (I):

[0105]

[0106] Wherein, R1 is selected from one of C6-C12 alkyls;

[0107] The second component includes one or more of sulfites, metabisulfites, and bisulfites;

[0237] The removal rates of 2-nonenal by 4-amino-1-butanol, 2,2'-dihydroxydiethylamine, and 2-amino-4-methylvaleric acid used in each comparative ratio are all less than 50%. The removal rates of 2-nonenal by 2,6-diaminohexanoic acid, pentyl dipropyltriamine, tetradecyl dipropyltriamine, hexylamine, sodium dithionite, and sodium thiosulfate used in each comparative ratio are all 100%

[0238] 2. Evaluation of the effect of removing aged odor

[0239] The washing products prepared in the above-mentioned examples and comparative ratios were evaluated for their effect of removing aged odor. The evaluation method is as follows:

[0240] a. Mix 2-nonenal and JB-03 sebum sewage (China Light Daily Chemical Inspection and Certification Co., Ltd., meeting the requirements of GB / T 13174) evenly at a ratio of 1:1000. Drop the mixed solution onto a circular cloth sample with a diameter of 8 cm, and the mass ratio of the liquid to the cloth sample is 0.02:0.65 (g:g). The cloth sample is all-cotton pique cloth (gram weight is 170 g / m 2 ). Obtain the aged odor-contaminated cloth for the next step.

[0241] b. The washing performance test of the washing product on the aged odor-contaminated cloth was carried out with reference to "Determination of the detergency and cyclic washing performance of detergents for fabric use (GB / T 13174-2021)". Prepare washing water with a hardness of 250 ppm according to "Determination of the detergency and cyclic washing performance of detergents for fabric use (GB / T 13174-2021)", where the molar ratio of calcium and magnesium ions is 3:2. Prepare a 0.06% washing solution of the washing product with 250 ppm washing water, and complete 1 wash with the RHLQ vertical decontamination machine of the China National Research Institute of Daily Chemical Industry. The washing time is 20 min, the washing temperature is 30 °C, and the stirring speed is 120 revolutions per minute. Immediately take out all the cloth samples and the washing solution after the washing is over for the next step.

[0242] It should be noted that in the evaluation method of the effect of removing aged odor of the washing product, the washing product washes the cloth sample (aged odor-contaminated cloth) under conventional washing conditions. The so-called conventional washing conditions refer to that the concentration of the water-soluble film-encapsulated liquid detergent composition in the washing system is 0.06%, and the washing time is 20 minutes.

[0243] c. Evaluation of the effect of removing aged odor: An expert panel was used to evaluate the removal effect of 2-nonenal on the washed aged odor-contaminated cloth and the washing solution. The expert panel is composed of 7 people with sensitive olfaction who have received professional training. Score the effect of removing aged odor according to the criteria in Table 4, and take the average value of the scoring results to evaluate the level of the effect of removing aged odor according to the criteria in Table 5. The higher the score, the worse the removal effect. The evaluation results of the effect of removing aged odor of each example and comparative ratio are shown in Table 6.

[0244] Table 4

[0245] Evaluation of the effect of removing aged odor Score There is no change in the aged odor before and after washing, very strong 5 The aged odor is slightly weakened after washing, but can be clearly perceived 4 The aged odor is significantly weakened after washing, but can still be perceived 3 The aged odor cannot be clearly perceived after washing, but the fragrance of the detergent solution has changed significantly 2 The aged odor cannot be clearly perceived after washing, but the odor of the detergent solution has changed slightly 1 There is no aged odor after washing, and the odor of the detergent solution has no obvious change 0

[0250] As can be seen from the results in Table 6, the evaluation grades of the aged odor removal effect of the washing products in Examples 1-8 are all good, indicating that the washing products provided by this application all have excellent aged odor removal effects.

[0251] In Comparative Example 1, the first component and the second component were not added during the preparation of the washing product, and it did not have the ability to remove 2-nonenal, and the evaluation grade of the aged odor removal effect was poor.

[0252] In Comparative Example 4, the content of the first component was 2.5% during the preparation of the washing product. Due to the too low dosage of the first component, the evaluation grade of the aged odor removal effect was average.

[0253] In Comparative Example 8, Comparative Example 9, and Comparative Example 11, 4-amino-1-butanol, 2,2'-dihydroxydiethylamine, and 2-amino-4-methylpentanoic acid with a 2-nonenal removal rate of less than 50% were used as the first component respectively. Even when the addition amount reached 6%, the evaluation grade of their aged odor removal effect was still poor.

[0254] 2. Test on the color change value of the content for the content stability performance

[0255] It should be noted that the "content" mentioned in the context refers to the washing liquid encapsulated by the water-soluble film of the washing product. The aging treatment refers to storing the liquid detergent composition encapsulated by the water-soluble film in an environment of 45°C and 75±5% relative humidity for four weeks.

[0256] No distinction is made between the terms aging treatment, aging experiment, high-temperature accelerated aging treatment, and high-temperature acceleration. The aging treatment in other parts of the following text is the same as this step.

[0257] The degree of color change of the content is quantitatively characterized by the following method. Use a color difference meter to measure the D b value (yellow-blue value) of the washing product before and after the aging treatment, and calculate the color change value (Y) of the content (that is, the washing liquid encapsulated by the water-soluble film) according to the following formula. Evaluate the color change value grade of the content of the washing product after the aging treatment according to Table 7 below.

[0258] Y = D b 2 - Db 1

[0259] Among them, Y: the value of the color change of the content; D b 1: D value (yellow - blue value) of the liquid detergent composition encapsulated in the water - soluble film before the aging treatment b value; D b 2: D value (yellow - blue value) of the liquid detergent composition encapsulated in the water - soluble film after the aging treatment b value.

[0260] Table 7

[0261]

[0262] The test results of the color change value of the content after the aging treatment of Examples 1 - 8 and Comparative Examples 2 - 3, Comparative Examples 5 - 7, Comparative Example 110, and Comparative Examples 12 - 16 are shown in Table 8. The appearance pictures of Example 1 before and after the aging treatment are respectively shown in Attachment Figure 4 and Attachment Figure 5 as shown. The appearance pictures of Comparative Example 3 before and after the aging treatment are respectively shown in Attachment Figure 6 and Attachment Figure 7 as shown.

[0265] As can be seen from the results in Table 8, after the aging treatment of the washing products in Examples 1 - 8, the color change values are all less than 6, and the color change value level is good, indicating that the content color stability of the washing products provided by this application is excellent.

[0266] In Comparative Example 3, the second component was not added when preparing the washing product, and the color change value of the washing product after the aging treatment was greater than 10, and the evaluation level was poor.

[0267] In Comparative Example 5, the content of the second component was 0.4% when preparing the washing product, and in Comparative Example 6, the content of the first component was 6.5% when preparing the washing product. The color change values of the washing products in Comparative Examples 5 - 6 after the aging treatment were both greater than 6, and the evaluation level was average. The ratio ranges of the first component and the second component in Comparative Examples 5 and 6 do not meet the requirements of the technical solution of this application and cannot achieve good results. It can be seen that too high an addition amount of the first component or too low an addition amount of the second component in the washing product will have a negative impact on the content color stability of the washing product.

[0268] In Comparative Examples 12 and 14, pentyl dipropyltriamine and hexylamine were respectively used as the first component when preparing the washing product, and the color change values of the washing products after the aging treatment were also both greater than 6, and the evaluation level was average.

[0269] 3. Content Integrity Test for the Stability of the Contents

[0270] As shown in Table 9, the integrity of the contents of the washing products after aging treatment was evaluated by visual inspection.

[0271] The steps of the aging treatment are as described above.

[0272] Table 9

[0273]

[0274] The test results of the integrity of the contents after aging treatment for Examples 1-8, Comparative Example 2, Comparative Example 7, Comparative Example 10, Comparative Example 13, Comparative Example 15, and Comparative Example 16 are shown in Table 10. The appearance pictures of Comparative Example 10 before and after aging treatment are shown in Figure 8 and Figure 9 respectively.

[0275] Table 10

[0276]

[0277] As can be seen from the results in Table 10, the evaluation grades of the integrity of the contents of Examples 1-8 are all good, indicating that the washing products provided by this application have excellent integrity of the contents.

[0278] In Comparative Example 10, 2,6-diaminohexanoic acid was used as the first component. Due to solubility problems, fine precipitates appeared in the contents of the washing product after aging treatment, and the evaluation grade of the integrity of the contents was average.

[0279] 4. Odor Stability Test for the Stability of the Contents

[0280] The odor of the contents of the washing products before and after aging treatment was tested.

[0281] The steps of the high-temperature aging treatment are as described above.

[0282] The test steps are as follows: Cut open the outer membrane of the washing product, squeeze out the contents into a culture dish with a diameter of 9 cm, and use an expert panel to evaluate the difference in odor before and after aging treatment. The expert panel consists of 5 people and scores the odor stability according to Tables 11 and 12 below.

[0283] Table 11

[0284] Grade Fragrance Strength Newly added abnormal odor No obvious change Consistent with the sample before aging Consistent with the sample before aging None No change Basically consistent with the sample before aging Consistent with the sample before aging None Consistent with the sample before aging Basically consistent with the sample before aging None There is a change Different from the sample before aging Do not need to detect Do not need to detect

[0285] Table 12

[0286]

[0287] The test results of odor stability after the aging treatment of Examples 1-8, Comparative Example 2, Comparative Example 7, Comparative Example 13, Comparative Example 15, and Comparative Example 16 are shown in Table 13.

[0288] Table 13

[0289]

[0290] As can be seen from the results in Table 13, after 4 weeks of aging treatment, the odor of the washing product content in Examples 1-8 did not change significantly, and the evaluation grade of temperature stability was good; indicating that the washing product provided by the present application has excellent odor stability of the content.

[0291] In Comparative Example 15 and Comparative Example 16, sodium dithionite and sodium thiosulfate were used as the second component respectively, and the odor of the content before and after aging treatment changed significantly, indicating that the odor stability of the washing product content prepared with sodium dithionite and sodium thiosulfate as the second component could not meet the requirements.

[0292] 5. Membrane Integrity Test of Membrane Stability Performance

[0293] It should be noted that the liquid detergent composition encapsulated by the water-soluble film has good membrane stability performance, specifically referring to that after undergoing aging treatment, its membrane integrity, degree of change in membrane appearance, and tactile performance evaluation grade are all good. The relevant test and evaluation methods are as follows.

[0294] The steps of the aging treatment are as described above.

[0295] Evaluate the membrane integrity after the aging treatment according to Table 14.

[0296] Table 14

[0297]

[0298] The evaluation results of membrane integrity after the aging treatment of Examples 1-8, Comparative Example 2, Comparative Example 7, and Comparative Example 13 are shown in Table 15. The appearance pictures of Comparative Example 7 before and after aging treatment are respectively as shown in Figure 10 and 11 shown.

[0299] Table 15

[0300]

[0301] As can be seen from the results in Table 15, after 4 weeks of aging treatment, the evaluation grades of membrane integrity in Examples 1-8 were all good; indicating that the washing product provided by the present application has excellent membrane integrity.

[0302] In Comparative Example 7, the content of the second component in the preparation of the washing product was 1.5%. The water-soluble film of the washing product wrinkled after the aging treatment, and the evaluation grade of the film integrity was average; indicating that too high content of the second component in the washing product would affect the film integrity.

[0303] 6. Test on the degree of change in film appearance of film stability performance

[0304] Evaluate the degree of change in film appearance after the aging treatment as shown in Table 16. The steps of the aging treatment are as described above.

[0305] Table 16

[0306]

[0307] The test results of the degree of change in film appearance after the aging treatment of Examples 1-8, Comparative Example 2 and Comparative Example 13 are shown in Table 17.

[0308] Table 17

[0309]

[0310] As can be seen from the results in Table 17, after 4 weeks of aging treatment in Examples 1-8, the evaluation grades of the degree of change in film appearance of the washing products are all good; indicating that the washing products provided by the present application have excellent film appearance stability.

[0311] 7. Test on the tactile performance of the film of film stability performance

[0312] According to Table 18, touch the outer film surface of the washing product after the aging treatment by hand to evaluate the tactile performance. 5 testers were used for each sample, and each person detected 2 times in parallel. The evaluation results were distinguished as "non-sticky" and "sticky". The steps of the aging treatment are as described above.

[0313] Table 18

[0314]

[0315] The test results of the tactile performance of the film after the aging treatment of Examples 1-15, Comparative Example 2 and Comparative Example 13 are shown in Table 19.

[0316] Table 19

[0318] As can be seen from the results in Table 19, the outer film surface of the washing products in Examples 1-8 is non-sticky after the aging treatment, and the evaluation grade of the tactile performance is good; indicating that the film tactile performance of the washing products provided by the present application is excellent.

[0319] In Comparative Example 13, tetradecyl dipropylenetriamine was used as the first component. After the aging treatment of the washing product, the outer film surface was sticky, and the tactile performance grade was evaluated as average.

[0320] 8. Dissolution Stability Test

[0321] The dissolution stability performance of the washing product refers to the good retention of the dissolution performance grade of the washing product after aging treatment. The test steps are as follows: Place 1 washing product into a beaker, stir and dissolve it in the beaker for 10 minutes, and then stop stirring. Immediately filter all the solutions and residues in the beaker through a 60-mesh sieve, and evaluate the dissolution performance according to the residue on the sieve within 5 minutes. Each sample is tested in parallel 5 times, and the dissolution stability performance is rated according to Tables 20 and 21. The steps of the aging treatment are as described above.

[0322] Table 20

[0323]

[0324] Table 21

[0325]

[0326] The dissolution stability test results of Examples 1-8 and Comparative Example 2 after aging treatment are shown in Table 22.

[0329] As can be seen from the results in Table 22, after 4 weeks of aging treatment, the dissolution stability performance evaluation grades of Examples 1-8 are good; indicating that the washing products provided by the present application have excellent dissolution stability.

[0330] 9. Evaluation of the Effect of Removing Aging Odor after Aging Treatment

[0331] The effect of removing aging odor of the washing product after aging treatment was evaluated according to the aging odor evaluation method described in "2. Evaluation of the Effect of Removing Aging Odor". The evaluation results of the effect of removing aging odor of Examples 1-8 and Comparative Example 2 after aging treatment are shown in Table 23. The steps of the aging treatment are as described above.

[0332] Table 23

[0333] Group Score of the effect of removing aged odor after aging treatment Evaluation grade Example 1 0.5 Good Example 2 0.7 Good Example 3 1.4 Good Example 4 0.6 Good Example 5 1.1 Good Example 6 0.9 Good Example 7 0.8 Good Example 8 0.7 Good Comparative example 2 2.4 General

[0334] As can be seen from the results in Table 23, after 4 weeks of aging treatment, the evaluation grade of the odor removal effect of Examples 1-8 remains unchanged and is still good; indicating that the washing products provided by the present application still have excellent aging odor removal effect after aging treatment.

[0335] In Comparative Example 2, the first component was not added when preparing the washing product, and only the second component, the sulfur-containing compound, was added. Possibly because the sulfur-containing compound has a certain reducibility and undergoes partial decomposition after the aging treatment, resulting in a decrease in the overall effect of removing aged odor.

[0336] 10. Skin irritation test

[0337] In this application, zein experiments were used to evaluate the skin irritation of the washing product. Zein has a similar protein structure to that in human skin and hair. After interacting with the washing product, its spatial conformation changes, thereby changing the water solubility of zein, and its water solubility will increase. The content of zein dissolved in the aqueous solution is proportional to the skin irritation it causes.

[0338] The test steps are as follows: (1) Prepare an aqueous solution of the 5% sample to be tested. (2) Add zein to the test solution under stirring at room temperature, and stir with a magnetic stirrer for about 4 h. (3) Centrifuge the above solution at 4000 rpm for 15 min and take the supernatant. (4) Use a kit (Pierce TM BCA Protein Assay Kit) from Thermo Fisher Scientific, USA to test the protein concentration C of the sample. According to the nitrogen content in the protein being 16%, calculate the ZEIN value (mgN / 100 mL).

[0339] ZEIN = C × 16

[0340] The higher the protein concentration C, the higher the ZEIN value, indicating that the sample has stronger irritation. The irritation of the detergent samples was evaluated according to Table 24 below.

[0341] Table 24

[0342] ZEIN value Skin irritation grade <200 Mild and non-irritating 200~400 Moderate irritation >400 Strong irritation

[0343] The skin irritation test results of Examples 1-15 and Comparative Example 1 are shown in Table 25.

[0344] Table 25

[0346] From the results in Table 25, it can be seen that the skin irritation levels of Examples 1-8 are "mild and non-irritating", indicating that the washing product provided in this application is non-irritating to the skin.

[0347] In Comparative Example 1, neither the first component nor the second component was added when preparing the washing product, and the skin irritation level of Comparative Example 1 was also "mild and non-irritating". This further shows that the first component and the second component added to the washing product in this application do not increase the skin irritation of the washing product and can give consumers a mild and comfortable use experience.

[0348] From the evaluation grades of the aged odor removal effect, the stability of the content, the stability of the film, the dissolution stability, and the irritation evaluation results before and after the aging treatment in the above Examples 1-8, it can be seen that the washing product of the present application not only has a good effect of removing the aged odor of the clothes of the elderly, but also has good stability. That is, after the washing product undergoes the aging treatment, the color change value of the content, the film integrity, the degree of film appearance change, the content integrity, the odor stability, and the dissolution stability are all good. Moreover, the evaluation grade of the aged odor removal effect after the aging treatment remains unchanged, no new odor is generated, and at the same time, it is mild and non-irritating to the skin.

[0349] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0350] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
