Description

[Technical Field]

[0001] The present invention relates to the technical field of daily cleaning products, and more particularly to an ultra-concentrated liquid detergent composition for deodorization and a method for preparing the same. [Background technology]

[0002] China's home care market has already exceeded 120 billion yuan and is showing steady growth, among which laundry detergents have become the largest subcategory of home care, accounting for more than 55% of the market share. Consumers have increasingly complex needs for cleaning and protecting their clothes, not only wanting to clean and remove dirt, disinfect and remove mites, and clean naturally, but also gradually increasing demand for diversification of scenarios and functions.

[0003] Market analysis shows that odor is extremely important to consumers. The number of newly launched cleaning products in China with "deodorizing" as a selling point has increased by 67% over the past five years, but their effectiveness is still insufficient. The main issues are that strong odors are difficult to remove, odors remain for a long time, odors frequently recur, unpleasant odors are generated when clothes are dried in the shade, sweat odors remain on freshly washed clothes, and stains are not completely removed, causing yellowing and stiffening of collars and underarm fabrics. The main cause of consumer inconvenience is human secretions.

[0004] Traditional cleaning techniques involve using essences to mask / neutralize the odor so that it is not detectable for a while, or disinfectants / bleach to kill bacteria and alleviate the odor for a while, but the secretions still exist and the problem is not fundamentally solved, so it may recur.

[0005] Another problem with conventional technology is that zinc ricinoleate is commonly added to deodorizing products, but the increased surfactant content in ultra-concentrated liquid detergents makes zinc ricinoleate incompatible with zinc ricinoleate, significantly reducing its deodorizing ability. As a result, conventional technology is unable to effectively remove daily accumulated body secretions.

[0006] In view of the above, in order to solve these drawbacks, it is necessary to develop a liquid cleaning agent that has both good deodorizing and decontamination effects. Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, the present invention provides an ultra-concentrated liquid detergent composition for deodorization containing zinc ricinoleate, a modified zinc complex, and a nuclease, and this ultra-concentrated liquid detergent composition for deodorization provides excellent decontamination and deodorization effects due to the synergistic effects of multiple components. [Means for solving the problem]

[0008] The object of the present invention is to provide an ultra-concentrated liquid detergent composition for deodorization, which comprises the following mass fractions of components: Surfactant 50-80wt% Zinc ricinoleate 0.1-10wt% Modified zinc complex 0.1-10wt% Nuclease 0.1-5wt% Auxiliary agent 0.1~10wt% solvent The modified zinc complex is obtained by reacting flavone, zinc ions, an amino acid, and a halide.

[0009] Furthermore, the method for producing the modified zinc complex includes the steps of: Step S1: adding an amino acid and a halide to deionized water and stirring uniformly; Step S2: Adding flavones and stirring to obtain a mixed solution; and step S3 of adding zinc ions to the mixture, reacting under ultrasonic waves, and then centrifuging and drying to obtain a modified zinc complex.

[0010] Furthermore, the flavone is selected from rutin, quercetin, baicalein, baicalin, glucoside, nobiletin, and myricetin.

[0011] Furthermore, the mass ratio of the zinc ions, amino acids, halides, and flavones is (0.1-10):(0.1-5):(0.05-3):1.

[0012] Furthermore, the amino acid is one or more selected from glycine, alanine, phenylalanine, glutamic acid, sarcosine, arginine, lysine, and histidine.

[0013] Furthermore, the halide is at least one selected from fluorides and chlorides.

[0014] Furthermore, the surfactant is one or more selected from anionic surfactants, nonionic surfactants, amphoteric surfactants, cationic surfactants, and fatty acids.

[0015] The anionic surfactant may be one or more surfactants selected from sulfonate, carboxylate, and sulfate surfactants, but is not limited thereto. Preferably, alkylbenzene sulfonate, C8 to C 18 Alkyl sulfonates of C8-C 18 The ethoxylated fatty alcohol sulfate, fatty acid alkyl ester sulfonate, and ethoxylated fatty alcohol ether carboxylate are one or more selected from the group consisting of ethoxylated fatty alcohol sulfate, fatty acid alkyl ester sulfonate, and ethoxylated fatty alcohol ether carboxylate.

[0016] The nonionic surfactant may be one or more selected from fatty alcohol polyoxyethylene ethers, fatty alcohol alkoxylates, fatty acid ethoxylates, and fatty acid alkyl alcohol amides, but is not limited thereto.

[0017] Furthermore, the nuclease is one or more selected from ribonucleases and deoxyribonucleases.

[0018] Furthermore, the auxiliary agent is one or more selected from the group consisting of a preservative, a chelating agent, a pH adjuster, an essence, and a coloring matter.

[0019] Another object of the present invention is to provide a method for producing the above-mentioned ultra-concentrated liquid detergent composition for deodorization, which comprises the steps of: Step L1: Add zinc ricinoleate and nuclease to a solvent and stir, then add a modified zinc complex to obtain solution 1, add an alkali and a surfactant to the reactor and stir evenly to obtain solution 2; and step L2 of adding the solution 1 to the solution 2 and stirring uniformly to obtain the deodorizing ultra-concentrated liquid detergent composition.

[0020] Furthermore, the mass ratio of the modified zinc complex to the nuclease is (1:1) to (10:1).

[0021] Furthermore, the solvent is one or more selected from water, ethanol, glycerin, propylene glycol, sorbitol, polyethylene glycol, diethylene glycol butyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, diethylene glycol butyl ether acetate, dipropylene glycol butyl ether, and tripropylene glycol butyl ether. [Effects of the Invention]

[0022] The effects of the present invention are as follows.

[0023] 1. The ultra-concentrated liquid detergent composition for deodorization according to the present invention contains zinc ricinoleate, a modified zinc complex, and a nuclease, and these three components exert a synergistic effect. The nuclease is supported and bound to the zinc ricinoleate, and the two are crosslinked by chemical bonds to form a core structure. The modified zinc complex has good compatibility and further coats the core, forming a stable and uniform outer layer. The high stability of this structure and the long-term stable presence of the nuclease-containing microparticles in the composition prevent the active ingredient from being inactivated or lost.

[0024] 2. In the present invention, the modified zinc complex prepared from flavones and amino acids has good solubility. During washing, the modified zinc complex in the outer layer gradually dissolves, releasing enzymes and zinc ricinoleate components to remove stains such as human body secretions and odorous molecules. The modified zinc complex can also adjust the action speed of the enzyme, thereby significantly extending its action time and achieving reliable decontamination and long-term deodorization technical effects, which is significantly improved compared with conventional technologies. DETAILED DESCRIPTION OF THE INVENTION

[0025] In order to more clearly explain the technical solution of the present invention, the following examples are given. Unless otherwise specified, the raw materials, reaction and post-treatment means shown in the examples are all common raw materials on the market and technical means well known to those skilled in the art.

[0026] In the embodiment of the present invention, the modified zinc complex is produced by the following method: Step S1: adding lysine and potassium chloride to deionized water and stirring uniformly; Step S2: adding quercetin and stirring to obtain a mixed solution; Step S3: adding zinc oxalate to the mixture, reacting for 2 minutes under ultrasonic waves, and then centrifuging and drying to obtain a modified zinc complex; Here, the ratio of zinc ions:lysine:potassium chloride:quercetin = 2:1:1:1, m / m / m / m.

[0027] Table 1 shows the components and the corresponding mass fractions in the examples and comparative examples of the present invention.

[0028] [Table 1]

[0029] The manufacturing methods of Examples 1 to 4 are as follows: Step L1: Add zinc ricinoleate and nuclease to deionized water in the above mass fractions and stir, then add modified zinc complex to obtain solution 1; add monoethanolamine, sodium hydroxide aqueous solution, glycerin, propylene glycol, alkylbenzene sulfonic acid, ethoxylated fatty alcohol sulfate, fatty alcohol polyoxyethylene ether, saturated fatty acid, oleic acid, and essence to a reactor and stir evenly to obtain solution 2; and step L2 of adding the solution 1 to the solution 2 and stirring uniformly to obtain an ultra-concentrated liquid detergent composition for deodorization.

[0030] Comparative Examples 1 to 3 were set up based on Example 1. The difference between Comparative Examples 1 to 3 and Example 1 is that the modified zinc complex was replaced with zinc lysine, a quercetin-zinc complex, or zinc ricinoleate, respectively, and the other ingredients and production methods were the same as those of Example 1.

[0031] The lysine zinc was prepared by omitting step S2 in the process of preparing the modified zinc complex.

[0032] The quercetin-zinc complex was prepared without adding lysine in step S1 in the process for producing the modified zinc complex.

[0033] Test Example 1: Stability test of cleaning composition

[0034] The test method is as follows.

[0035] Low-temperature stability test: The detergent compositions were individually bottled and sealed, then placed in an environment with a temperature of -0±2°C. After leaving them at constant temperature for 2 months, they were taken out and immediately observed. If there was no significant discoloration, phase separation, or precipitation in the detergent compositions, they were judged to have passed the low-temperature stability test.

[0036] Constant temperature and humidity stability test: After the detergent composition was bottled and sealed, it was placed in an environment of 37±2°C and 75% humidity, and left at constant temperature for 2 months. After leaving it at constant temperature, it was taken out and immediately observed. If there was no significant discoloration, phase separation, or precipitation in the detergent composition, it was judged to have passed the constant temperature and humidity stability test.

[0037] Room temperature stability test: After the detergent composition was bottled and sealed, it was placed in an environment with a temperature of 25±2°C and left at a constant temperature for 2 months. After leaving it at this temperature, it was taken out and the condition was immediately observed. If there was no significant discoloration, phase separation, or precipitation in the detergent composition, it was judged to have passed the room temperature stability test.

[0038] High-temperature stability test: The detergent composition was bottled and sealed, then placed in an environment of 45±2°C, and left at constant temperature for 2 months. The condition was then immediately observed after removal. If the detergent composition showed no significant discoloration, phase separation, or precipitation, it was judged to have passed the high-temperature stability test.

[0039] The results obtained are shown in Table 2.

[0040] [Table 2]

[0041] As can be seen from Table 2, the detergent compositions prepared in Examples 1 to 4 passed the stability test even when left at different temperatures for 2 months. However, in Comparative Examples 1 and 2, the modified zinc complex was substituted, so a stable core-shell structure could not be formed, and the sample exhibited precipitation or sedimentation at different temperatures depending on the surfactant content. Comparative Example 3 did not contain zinc ricinoleate, and only the modified zinc complex was added, and this sample also exhibited precipitation during the test.

[0042] Test Example 2: Decontamination performance test of cleaning composition

[0043] The decontamination test was conducted in accordance with GB / T 13174 2008, "Measurement of the decontamination power and circulating cleaning performance of laundry detergents." The results are shown in Table 3. Here, the P value represents the decontamination ratio. Generally, standard laundry liquid is used as the reference sample, and its decontamination ratio is set to 1.00. The higher the P value, the better the cleaning power.

[0044] [Table 3]

[0045] As is clear from Table 3, the detergent compositions of Examples 1 to 4 were clearly superior in decontamination effect against carbon black, protein, and sebum to Comparative Examples 1 to 3 and the standard laundry liquid. Surprisingly, Comparative Example 3 had better decontamination ability against protein and sebum than Comparative Examples 1 and 2. This suggests that the amino acids in the modified zinc complex act synergistically with phosphodiesterase to exert a decomposition action on three substances: sugars metabolized by the human body, sebum, and protein, resulting in the remarkable decontamination effect of the compositions against protein and sebum.

[0046] Test Example 3: Deodorizing ability test of cleaning composition

[0047] Test Method: 1. Two identical 10cm x 10cm pieces of sweat-smelling cotton fabric (sweat-smelling T-shirts, manufactured by the China Institute of Daily Chemicals) were prepared and weighed before washing. 2. 1000g of tap water was added to an appropriately sized basin, followed by 2.00g of regular laundry detergent. 3. The weighed sweat-smelling cotton fabric was placed in the basin and soaked for 2 minutes. It was rubbed 30 times on each side, then wrung out to control the moisture content to 150%-160%. 4. It was rinsed twice with 1L of tap water, rubbed 30 times on each side, wrung out, controlled the moisture content to 150%-160%, and finally air-dried. 5. The deodorizing effect of the washed and dried sweat-smelling cotton fabric was evaluated.

[0048] Deodorization results and evaluation: Ten evaluators were selected to evaluate the odor of fabrics washed with the test sample. Using the odor (sweat odor) of the fabric before washing as the standard, they judged the extent to which the odor (sweat odor) remained on the fabric after washing and assigned a score to the washed fabric. The washed fabric was divided into a wet odor (smelled before drying) and a dry odor (smelled after drying). The scoring system was divided into three levels out of a total of 50 points, with 0-10 indicating essentially no odor, 10-30 indicating a slight odor, and 30-50 indicating a clear odor. If the average score was 0-10, the sample was judged to have "effectively removed the odor (sweat odor)."

[0049] The deodorizing effect was evaluated immediately after washing the cotton fabric as time point 1, after the cotton fabric was dry as time point 2, and after the cotton fabric had been stored in a sealed bag for two weeks as time point 3. The evaluators evaluated the deodorizing effect at each of the three evaluation time points. The final test result was the average of the scores.

[0050] [Table 4]

[0051] The deodorization test results shown in Table 4 demonstrate that the cleaning compositions of Examples 1 to 4 not only remove off-flavors but also prevent their recurrence during sealed storage. The amino acids and halides added to the modified zinc complexes exert catalytic effects on nucleases while ensuring nuclease activity in highly surfactant environments. On the other hand, Comparative Examples 1 to 3 have difficulty forming stable crosslinked structures, inhibiting nuclease activity in highly surfactant environments. The composition of the modified zinc complex, zinc ricinoleate, and nuclease of the present invention reacts with multiple off-flavoring molecules, such as hydrogen sulfide, mercaptan, thioether, formaldehyde, isovaleric acid, and ammonia, to fundamentally eliminate off-flavors and prevent their recurrence.

[0052] Test Example 4 Collar Cleaning Ability Test of Detergent Composition

[0053] Test method: Two identical cotton fabrics (sweaty T-shirts, manufactured by the China Institute of Daily Chemicals) were placed in a sealed bag and aged in a 45°C oven for two hours, then placed in a pulsator washing machine, 10g of ultra-concentrated detergent was added, washed in the mixed wash mode, dried, and then evaluated.

[0054] Results and Judgment: Ten evaluators were selected to evaluate the yellowing of the collars of T-shirts after washing with the test samples. Using a non-yellowing T-shirt as the standard, they judged the degree of yellowing of the collars of the T-shirts after washing. They then scored the yellowing of the collars of the T-shirts, and the scoring level of the fabric after washing was divided into three levels out of 5, with 0-2 indicating no marks at all, 1-3 indicating slight yellowing marks, and 3-5 indicating obvious yellowing marks. If 80% or more of the evaluators rated that no marks remained, the sample was judged to have "effectively removed the yellowing marks." The final test results were all the average of the scores.

[0055] [Table 5]

[0056] As can be seen from Table 5, the zinc ricinoleate, modified zinc complex, and nuclease in the examples can penetrate into clothing fibers to remove human secretions and other stains, reduce the yellowing caused by the oxidation of these stains, and have good cleaning ability, which is clearly superior to Comparative Examples 1 to 3 in which certain components were replaced or omitted.
