Description

Technical Field

[0001] This application relates to the field of fabric decontamination products. More specifically, it relates to a fabric fragrance-retaining decontamination composition containing an anionic surfactant and a preparation method thereof. Background Art

[0002] Since the launch of fragrance-retaining beads in the market in 2011, they have gradually become one of the important products in laundry care products. Polyethylene glycol (PEG) is a non-toxic, odorless, and tasteless substance, and its combustion products are carbon dioxide and water vapor, which will not pollute the environment. Therefore, most of the common fragrance-retaining beads and fragrance agents currently use PEG as the main component, and its weight ratio is as high as 90%.

[0003] However, there are still some defects in the fragrance-retaining beads prepared with polyethylene glycol as the main body. For example, PEG needs to be melted at high temperature, and the fragrance needs to be added and mixed at high temperature. This preparation process is likely to cause fragrance loss; and during the cooling and granulation process, a low-temperature environment needs to be maintained for a long time. Whether it is the mixing process or the granulation process, a large amount of energy is consumed. On the other hand, when the temperature is higher than 50°C, the fragrance-retaining beads prepared with polyethylene glycol as the main body are prone to self-melting, resulting in adhesion between particles and forming lumps, which affects product quality and consumer experience.

[0004] Patent CN202311310054.3 provides a high-temperature resistant fragrance-retaining bead and a preparation method thereof. The finished fragrance-retaining bead prepared by encapsulating with up to 90% of enzymatically hydrolyzed starch has the advantage of being resistant to high temperature of 50°C. However, enzymatically hydrolyzed starch is a small-molecule starch and is a direct carbon source for bacteria and fungi. After the finished fragrance-retaining bead is opened by consumers many times, the enzymatically hydrolyzed starch gradually absorbs moisture, and the microorganisms in the air will cause the fragrance-retaining bead to mildew. In addition, the fragrance-retaining bead contains 0.01 - 40 parts of water. Although water can wet the starch-based filler, the starch absorbs water and swells, loses its crystallinity, and becomes a viscous paste, making different materials mix more closely, and at the same time reducing the gelatinization temperature of the starch; but too much water will cause the material to soften during the screw extrusion process, reducing the yield. Moreover, when water is mixed with low-carbon chain alcohols or water-soluble high-molecular compounds, due to hydrogen bond association, it is difficult to completely remove the water during the extrusion granulation step. Setting too high an extrusion temperature to remove the water may cause the material to burn and fragrance loss, and at the same time, an additional drying process is required to remove the water, which further increases the fragrance loss. Summary of the Invention

[0005] Aiming at the above-mentioned disadvantages and deficiencies, the purpose of this application is to provide a fabric fragrance-retaining and stain-removing composition containing an anionic surfactant and a preparation method thereof. During the preparation process of this application, no water needs to be added, which can avoid the generation of microorganisms in the product and can also prepare a product without preservatives. The fragrance-retaining and stain-removing composition obtained by this preparation method has the characteristics of being resistant to high temperature of 55°C, high humidity, and instant solubility in cold water, and has the effects of stain removal, long-lasting fragrance retention, and good antibacterial, bacteriostatic, and acaricidal effects on fabrics.

[0006] In the first aspect, this application provides a fabric fragrance-retaining and stain-removing composition containing an anionic surfactant, adopting the following technical solution: A fabric fragrance-retaining and stain-removing composition containing an anionic surfactant, by weight percentage, comprises the following preparation raw materials: 5-29% binder, 10-35% anionic surfactant, 5-60% filler, 1-6% water softener, 0.5-5% auxiliary agent, 0.01-2% antioxidant, 0.05-1% antibacterial and acaricidal agent, 1-15% essence; The binder includes binder A, binder B, and binder C; in the preparation raw materials of the fabric fragrance-retaining and stain-removing composition, the weight percentage of binder A is 5-20%, the weight percentage of binder B is 0.5-10%, and the weight percentage of binder C is 0.05-4%; Binder A includes at least one of sucrose, glucose, fructose, and lactose; Binder B includes at least one of polyethylene glycol and polypropylene glycol; Binder C includes at least one of sucrose fatty acid ester, polyethylene glycol glucoside fatty acid ester, PEG-120 methyl glucose triisostearate, and PEG-120 methyl glucoside dioleate.

[0007] Preferably, the anionic surfactant includes at least one of sodium alkyl sulfate, α-olefin sulfonate, sodium cocoyl methyl taurate, and sodium lauroyl glutamate.

[0008] Preferably, binder A is sucrose, binder B is polyethylene glycol and polypropylene glycol, and binder C is sucrose fatty acid ester, polyethylene glycol glucoside fatty acid ester, and PEG-120 methyl glucoside dioleate; In the preparation raw materials of the fabric fragrance-retaining and stain-removing composition, the weight percentage of sucrose is 12-18%, the weight percentage of polyethylene glycol is 1-9%, the weight percentage of polypropylene glycol is 1-8%, the weight percentage of sucrose fatty acid ester is 0.1-3%, the weight percentage of polyethylene glycol glucoside fatty acid ester is 0.5-1.5%, and the weight percentage of PEG-120 methyl glucoside dioleate is 0.1-3%.

[0009] Preferably, in the raw materials for preparing the fabric fragrance - retaining and stain - removing composition, the weight percentage of sucrose is 12 - 18%, the weight percentage of polyethylene glycol is 3 - 6%, the weight percentage of polypropylene glycol is 0.5 - 2%, the weight percentage of sucrose fatty acid ester is 0.5 - 1.5%, the weight percentage of polyethylene glycol glucoside fatty acid ester is 0.5 - 1.5%, and the weight percentage of PEG - 120 methyl glucoside dioleate is 0.5 - 1.5%.

[0010] By adopting the above - mentioned technical solution, the adhesives are selected as sucrose, glucose, fructose, and lactose. These substances have moderate adhesiveness, which can not only ensure the tight combination between materials but also prevent over - adhesion from affecting the appearance of the product.

[0011] And polyethylene glycol, polypropylene glycol, sucrose fatty acid ester, polyethylene glycol glucoside fatty acid ester, PEG - 120 methyl glucose triisostearate, and PEG - 120 methyl glucoside dioleate contain a large number of hydroxyl groups in their molecules. On the one hand, these hydroxyl groups can form hydrogen bonds with water molecules, thus "locking" the water in their molecular structures. When the humidity in the environment is high, these substances can quickly absorb and retain this water. On the other hand, they also have excellent film - forming properties. After being mixed with other powders, at a certain temperature, they will quickly form a film on the surface of other powder particles that can isolate the external moisture and can also tightly bond different material powders together.

[0012] Preferably, anionic surfactants such as sodium alkyl sulfate, α - olefin sulfonate, sodium cocoyl methyl taurate, and sodium lauroyl glutamate not only have good stain - removing performance but can also be used as wetting agents. When the fabric fragrance - retaining composition is placed in a large amount of water, it can make water molecules better penetrate into the interior of the fabric fragrance - retaining composition, thereby improving the dispersion and solubility of the fabric fragrance - retaining composition.

[0013] Preferably, the particle sizes of the adhesive A, adhesive B, and adhesive C are 50 - 200 mesh.

[0014] Preferably, the filler includes at least two of maltodextrin, cyclodextrin, plant starch, porous starch, and cellulose.

[0015] Preferably, the filler is maltodextrin, cyclodextrin, plant starch, porous starch, and cellulose. In the raw materials for preparing the fabric fragrance - retaining and stain - removing composition, the weight percentage of maltodextrin is 5 - 10%, the weight percentage of cyclodextrin is 3 - 7%, the weight percentage of plant starch is 5 - 15%, the weight percentage of porous starch is 3 - 7%, and the weight percentage of cellulose is 1 - 5%.

[0016] Preferably, the plant starch includes one or a mixture of tapioca starch, corn starch, potato starch, pea starch, corn starch, and tapioca starch.

[0017] Preferably, the cellulose is microcrystalline cellulose.

[0018] By adopting the above technical solution, the filler is further optimized. Under the shearing, friction and heating effects of the screw extruder, filler materials such as dextrin and starch are gelatinized and expanded, causing the dextrin and starch to undergo a phase change, enhancing the toughness and expansibility of the closed structure, and forming more pore structures inside the fragrance-retaining and stain-removing composition. When placed in water, water enters the interior of the fragrance-retaining and stain-removing composition through the pore structures, promoting its dispersion and dissolution in water; at the same time, it is also beneficial for dispersing the colorant, making the appearance color of the product uniform and more beautiful.

[0019] Moreover, in the fragrance-retaining and stain-removing composition, the combined cooperation of binder A, filler, and anionic surfactant can effectively hinder the heat transfer, slowing down the heat transfer rate of binders B and C in a high-temperature environment, and enhancing the high-temperature resistance of the fragrance-retaining and stain-removing composition.

[0020] Preferably, the antibacterial and acaricidal agent includes at least one of dichlorobenzyl alcohol, cymene, Chinese prickly ash extract, and rice husk extract.

[0021] Preferably, the antibacterial and acaricidal agent is a mixture of Chinese prickly ash extract and rice husk extract. In the preparation raw materials of the fabric fragrance-retaining and stain-removing composition, the weight percentage of Chinese prickly ash extract is 0.2 - 2%, and the weight percentage of rice husk extract is 0.05 - 0.65%.

[0022] Preferably, the auxiliary agent includes at least one of glycerol, propylene glycol, butylene glycol, hexylene glycol, sorbitol, and isooctanol.

[0023] Preferably, the water softener includes at least one of sodium citrate, tetrasodium iminodisuccinate, tetrasodium glutamate diacetate, and trisodium methylglycine diacetate.

[0024] Preferably, the antioxidant includes one or a mixture of butylated hydroxytoluene, ascorbyl palmitate, and tert-butylhydroquinone.

[0025] Preferably, the alkyl sulfate includes one or a mixture of sodium dodecyl sulfate, sodium tetradecyl sulfate, sodium hexadecyl sulfate, sodium octadecyl sulfate, and sodium eicosyl sulfate.

[0026] Preferably, the fragrance includes liquid fragrance and microcapsule fragrance.

[0027] Preferably, in the preparation raw materials of the fabric fragrance-retaining and stain-removing composition, the weight percentage of liquid fragrance is 1 - 15%, and the weight percentage of microcapsule fragrance is 1 - 10%.

[0028] Preferably, the fabric fragrance - retaining and stain - removing composition has a length and width of 3 mm - 10 mm, a thickness of 0.6 mm - 3 mm, and a density of 0.6 - 1.2 g / ml.

[0029] An appropriate amount of colorant can be added to the fabric fragrance - retaining and stain - removing composition according to actual requirements.

[0030] In a second aspect, the present application provides a preparation method of a fabric fragrance - retaining and stain - removing composition containing an anionic surfactant, adopting the following technical solution: A preparation method of a fabric fragrance - retaining and stain - removing composition containing an anionic surfactant includes the following steps: mixing various preparation raw materials and stirring them into dry granular form, then heating and melting at 65°C - 75°C and extruding and granulating to obtain the fabric fragrance - retaining and stain - removing composition containing an anionic surfactant.

[0031] By adopting the above - mentioned technical solution, the present application does not add extra water, extrudes at a temperature of 65°C - 75°C, realizes the tight adhesion between materials, and avoids the manufacturing processes of high - temperature drying of moisture and additionally increasing the drying of moisture. Through the mutual cooperation of binder A, binder B, binder C, filler and anionic surfactant, the prepared fragrance - retaining and stain - removing composition has excellent properties such as resistance to high temperature of 55°C, high humidity resistance, and instant solubility in cold water.

[0032] Moreover, for the fragrance - retaining and stain - removing composition provided by the present application, only a small amount of antibacterial and acaricidal agent is added, and the effect of highly efficient acaricidal can be achieved.

[0033] In summary, the present application has the following beneficial effects: 1. High - temperature resistance: With the common cooperation of binder A, filler, anionic surfactant, etc., the composition is endowed with the property of resistance to high temperature of 55°C, enabling the composition to maintain excellent performance in various high - temperature application scenarios.

[0034] 2. Moisture resistance: In the present application, substances such as polyethylene glycol and polypropylene glycol are preferably used, which contain a large number of hydroxyl groups. These hydroxyl groups can form hydrogen bonds with water molecules, effectively "locking" the water, so that the fragrance - retaining and stain - removing composition shows excellent moisture - resistance performance.

[0035] 3. Water - free: The preparation of the present application does not require extra water addition, avoiding the problem of microbial contamination caused by water introduction, and also eliminating the manufacturing process of high - temperature drying of moisture. 4. Rapid dissolution: The gelatinization and expansion of fillers such as dextrin and starch under the shearing, friction and heating of the screw extruder form more pore structures. And with the preferred anionic surfactant, water molecules can quickly penetrate and wet the interior through these pore structures, promoting dispersion and dissolution in water, endowing the fragrance - retaining and stain - removing composition with the characteristic of instant solubility in cold water.

[0091] Performance detection test 1. Detergency test: According to GB / T 13174-2021 Determination of Detergency and Repeated Wash Performance of Laundry Detergents, the washing water is 250 mg / kg CaCl2 hard water, and the test cloth pieces are national standard carbon black JB-01 soiled cloth, national standard protein JB-02 soiled cloth, and national standard sebum JB-03 soiled cloth, and the detergency is determined.

[0092] Taking 0.2% standard laundry detergent as the control, the detergency ratio Pi is obtained. When Pi≥1.0, it is qualified; when Pi<1.0, it is unqualified. The results are recorded in Table 2.

[0093] Table 2 2. Dissolution test: At 10 °C, 15 °C, and 25 °C, 0.50 g of the composition is quickly added to a 300 mL beaker containing 250 mL of ultrapure water with a rotation speed of 800 r / min and a rotor size of φ8 mm×25 mm, and the timing starts; the timing is terminated until the dispersion state of the composition in the system no longer changes; this time is the dispersion time of the composition.

[0094] The results are recorded in Table 3.

[0095] Table 3 For the compositions of Comparative Examples 4, 6, and 7, the dispersion time at 25°C is 14 - 20 minutes, which is caused by the poor water solubility of PEG, and it is even more difficult to dissolve at low temperatures. In winter, the water temperature is relatively low, and if it is not completely dissolved, it will remain on the fabric, resulting in poor effects.

[0096] Although the pregelatinized starch has strong water dispersibility and adhesiveness, the pregelatinized starch is prone to overcooking and gelatinization at high temperatures, increasing the dissolution and dispersion time of Comparative Example 8, and it is difficult to completely dissolve at low temperatures, and the effect is also poor.

[0097] However, the compositions of Examples 1 - 9 can all be dissolved within 8 minutes at a relatively low temperature of 10°C, and can be completely dissolved during the washing stage in the current 15 - minute quick - wash mode, with good washing effects.

[0098] 3. High - temperature resistance test: Keep the compositions at 45°C ± 2°C, 55°C ± 2°C, and 60°C ± 2°C for one month respectively, and observe whether there are phenomena such as deformation, cracking, adhesion, and color change when restored to room temperature.

[0099] Record the results in Table 4.

[0100] Table 4 4. Moisture resistance test: At 40°C ± 2°C, keep the compositions at 60% RH and 70% RH for one month respectively, and observe whether there are phenomena such as adhesion and color change when restored to room temperature.

[0101] Record the results in Table 5.

[0102] Table 5 5. Evaluation test of fragrance - retaining effect: Disperse 2.0 g of the composition in 1 L of CaCl2 hard water with a specification of 250 mg / kg until the appearance no longer changes to obtain the test sample solution.

[0103] Open the vertical stain - removal testing machine, transfer the above - mentioned test sample solution to the stain - removal tank, and preheat it at 30°C ± 1°C. Put 8 JB - 00 test pieces into the stain - removal tank, stir at 120 r / min for 20 min, and conduct a blank test simultaneously.

[0104] After the washing is completed, transfer the test pieces to a rinser and drain the water. Add 1500 mL of tap water and rinse for 30 s. After draining the rinsing water, manually dehydrate and spin-dry for 15 s. Repeat the above steps for a total of two rinses.

[0105] Take out the test pieces and place them in an enamel tray. Let them dry at room temperature in a cool and dry place. After drying, conduct the evaluation of the fragrance retention effect.

[0106] When evaluating, the evaluators should first rub the JB-00 test piece. Keep a distance of 1 cm to 2 cm between the JB-00 test piece and the nose. Do not let the JB-00 test piece touch the nose, and slowly inhale.

[0107] The inspectors should fill in the evaluation results of the subjects according to Table 6 and draw an "○" in the selected blank.

[0108] Summarize the results in Table 7.

[0109] 6. Evaluation of the long-lasting fragrance retention effect: After the evaluation of the fragrance retention effect is completed, hang the test pieces separately in the evaluation room one by one. Conduct the evaluation of the fragrance retention effect again on the 7th, 30th, 60th, and 100th days.

[0110] Summarize the results in Table 7.

[0111] Table 6 Note: The number of evaluators is 50. The table should be increased or decreased according to the actual number of evaluators.

[0112] Result determination, the calculation formula is as follows: In the formula, Y: the percentage of evaluators who can smell the fragrance; A: the number of evaluators who can smell the fragrance; B: the number of evaluators who cannot smell the fragrance.

[0113] When Y ≥ 80%, it can be determined that the product has the fragrance retention effect. When the test piece still has the fragrance retention effect after drying for X hours (days), it indicates that the test sample "has the fragrance retention effect for X hours (days)". When X ≥ 48 h, it indicates that the test sample "has the long-lasting fragrance retention effect for X hours (days)".

[0114] Table 7 7. Test for moisture and volatile content: The test was carried out in accordance with the provisions of Chapter 15 of GB / T 13173-2021 "Test Methods for Surfactants - Detergents". First, the weighing bottle was dried to a constant weight, then 2 g of the composition was accurately weighed into the weighing bottle, placed in an oven at (105±2)°C for 4 h, cooled and weighed, and the content of moisture and volatile matter in the sample was calculated.

[0115] Record the results in Table 8.

[0116] Table 8 In Examples 1 - 9, Comparative Examples 4 and 6, since no additional water was added, the content of moisture and volatile matter obtained from the test corresponded to the amount of added fragrance. It can be seen from Table 8 that after storage at 25°C for one month after preparation, the loss of fragrance in Examples 1 - 9 was relatively low, and 80% of the test cloths washed with Examples 1 - 9 were considered to have a fragrance after 100 days, indicating long-lasting fragrance retention. Compared with Example 1, the content of moisture and volatile matter obtained from the tests of Comparative Examples 4 and 6 was lower than that of Example 1, indicating that fragrance loss occurred during the granulation process in Comparative Examples 4 and 6. In Comparative Examples 1 - 3, since sucrose and sodium chloride crystals were used as carriers, moisture absorption caused the test result content to be greater than the added amount of fragrance, and the fragrance was physically adsorbed on the surface, making the fragrance easily volatile during daily storage and resulting in non-persistent fragrance retention. In Comparative Examples 5 and 7, 40 - 50% water was added during the mixing process, and the fragrance beads contained more moisture, making them more prone to moisture absorption, not only with non-persistent fragrance retention but also prone to mildew. The addition of water made the material body stick together more tightly. In order to remove the moisture, the temperature in the screw extrusion granulator for Comparative Examples 5 and 7 needed to be set at 90 - 100°C, increasing the loss of fragrance and making it difficult to completely remove the moisture, resulting in non-persistent fragrance retention.

[0117] 8. Demite Test Dissolve 8 g of the composition thoroughly in 4 L of 250 mg / kg CaCl2 hard water to obtain the test sample solution. Using a vertical stain removal tester, transfer the above test sample solution to the stain removal tank and preheat it at 30°C±1°C. Put the JB-00 test piece containing mites into the stain removal tank, stir at 120 r / min for 20 min, rinse three times, and count the number of remaining mites on the test piece.

[0118] The calculation formula is as follows, and record the results in Table 9.

[0119] In the formula: Z: Demite removal rate; C: Number of mites on the test cloth after washing; D: Number of mites on the test cloth before washing.

[0120] Table 9 Refer to the state diagrams of the compositions of Example 1, Example 2, Example 3, and Example 4 stored at 60°C for 20 months. Figure 2 After each composition was stored at 60°C for 20 months, there was no adhesion and no abnormality.

[0121] Refer to the state diagrams of the compositions of Example 1, Comparative Example 1, Comparative Example 6, and Comparative Example 8 placed at 25°C and 60°C for 1 month. Figure 3 . From Figure 3 it can be seen that Example 1 still maintained a good state, but the compositions of Comparative Example 1, 6, and 8 showed varying degrees of adhesion and abnormality, especially in the placement test at 60°C.

[0122] Refer to the state diagrams of the compositions of Comparative Examples 1-3 and Comparative Example 5 stored at 25°C for 1 month. Figure 4 The composition of Comparative Example 1 showed adhesion into a mass and sticking to the wall. The composition of Comparative Example 2 showed caking. The composition of Comparative Example 3 showed caking. The composition of Comparative Example 5 showed adhesion.

[0123] Refer to the state diagram of the composition of Comparative Example 4 stored at 55°C for 1 month. Figure 5 The composition of Comparative Example 1 showed adhesion.

[0124] Refer to the state diagram of the composition of Comparative Example 1 stored at 25°C for 6 months. Figure 6 The composition of Comparative Example 1 showed adhesion, and the components on the surface of the sucrose balls fell off, changed color, and absorbed moisture.
