Description

Technical Field

[0001] The present invention belongs to the technical field of daily cleaning products, and particularly relates to a super-concentrated liquid detergent composition for deodorization and a manufacturing method thereof.

Background Art

[0002] The scale of the Chinese home care market has already exceeded 120 billion yuan, and moreover, the growth is stable. Among them, laundry detergents have already become the largest sub-category of home care, occupying a share of more than 55%. Consumers have increasingly complex demands for the cleaning and protection of clothes. They not only require cleanliness, dirt removal, disinfection, mite removal, and natural freshness, but also the diversified demands for scenarios and functions are gradually increasing.

[0003] Market analysis has shown that smell is very important to consumers. Among the newly launched detergent products in China, those with "deodorization" as a selling point have increased by 67% in five years, but the effect is still not sufficient. The main problems are that strong unpleasant odors are difficult to remove, the unpleasant odors cannot be removed over a long period, the unpleasant odors frequently recur, there is an unpleasant smell when clothes are dried indoors, the smell of sweat remains on freshly washed clothes, and the dirt cannot be completely removed, resulting in yellowing or hardening of the fabrics at the collar and under the armpits. The cause of the trouble to consumers is human secretions.

[0004] The corresponding methods in the conventional cleaning technology are, firstly, using essence to hide / neutralize unpleasant odors so as not to perceive the unpleasant odors temporarily, and secondly, using disinfectants / bleaching agents to sterilize bacteria to relieve the unpleasant odors temporarily. However, the secretions still exist and the problems have not been fundamentally solved, so they may recur.

[0005] Another challenge with conventional technology is that while zinc ricinoleate is commonly added to deodorizing products, the increased surfactant content in highly concentrated liquid detergents leads to poor compatibility with zinc ricinoleate, significantly reducing its deodorizing ability. Therefore, conventional technology cannot effectively remove the body's secretions that accumulate daily.

[0006] Therefore, in order to overcome these shortcomings, it is necessary to develop a liquid cleaning agent that combines good deodorizing and decontamination effects. [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] Therefore, the present invention provides an ultra-concentrated liquid detergent composition for deodorization containing zinc ricinoleate, a modified zinc complex, and a nuclease. This ultra-concentrated liquid detergent composition for deodorization provides excellent decontamination and deodorization effects through the synergistic action 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. The ultra-concentrated liquid detergent composition for deodorization contains the following components in the following mass fractions: Surfactant 50-80 wt% Zinc ricinoleate 0.1-10 wt% Modified zinc complex 0.1~10 wt% Nuclease 0.1-5 wt% Additive agent 0.1-10 wt% solvent The modified zinc complex is obtained by the reaction of a flavone, zinc ions, an amino acid, and a halide.

[0009] Furthermore, the method for producing the modified zinc complex is as follows: Step S1 involves adding amino acids and halides to deionized water and stirring uniformly, Step S2 involves adding flavones and stirring to obtain a mixture, The step includes adding zinc ions to the aforementioned mixture, reacting under ultrasonic waves, then centrifuging and drying to obtain a modified zinc complex (step S3).

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

[0011] Furthermore, the mass ratio of 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, or histidine.

[0013] Furthermore, the halogen 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 selected from sulfonate type, carboxylate type, and sulfate type surfactants, but is not limited to these. Preferably, alkylbenzene sulfonate, C8-C 18 Alkyl sulfonates, C8~C 18 It is one or more selected from ethoxylated aliphatic alcohol sulfates, fatty acid alkyl ester sulfonates, and ethoxylated aliphatic alcohol ether carboxylates.

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

[0017] Furthermore, the nuclease is one or more selected from ribonuclease and deoxyribonuclease.

[0018] Furthermore, the auxiliary agent is one or more selected from preservatives, chelating agents, pH adjusters, essences, and pigments.

[0019] Another object of the present invention is to provide a method for manufacturing the above-mentioned super-concentrated liquid detergent composition for deodorization. The manufacturing method includes Step L1 of adding zinc ricinoleate and nuclease to a solvent, stirring, then adding a modified zinc complex to obtain Solution 1, and adding an alkali and a surfactant to a reaction kettle and stirring uniformly to obtain Solution 2; Step L2 of adding Solution 1 to Solution 2, stirring uniformly to obtain the super-concentrated liquid detergent composition for deodorization.

[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.

Advantages of the Invention

[0022] The advantages 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 nuclease, and these three components exhibit a synergistic effect. Nuclease is supported and bound to zinc ricinoleate, and the two are cross-linked by a chemical bond to form a core structure. In addition, the modified zinc complex has good compatibility and further coats the core to form a stable and uniform outer layer. Due to the strong stability of such a structure and the stable existence of the microparticles containing nuclease in the composition over a long period of time, the inactivation and invalidation of the active ingredients can be avoided.

[0024] 2. In the present invention, the modified zinc complex prepared from flavone and amino acid has good solubility. During washing, the outer-layer modified zinc complex gradually dissolves, releasing the enzyme and zinc ricinoleate components, removing stains such as human body secretions and odor molecules, and the modified zinc complex can adjust the action rate of the enzyme, thus greatly extending its action time and achieving the technical effects of reliable decontamination and long-term deodorization, which is significantly improved compared with the prior art.

Embodiments for Carrying out the Invention

[0025] In order to more clearly explain the technical solution of the present invention, the following examples are given. The raw materials, reactions, and post-treatment means appearing in the examples are all raw materials commonly found in the market and technical means well-known to those skilled in the art, unless otherwise specified.

[0026] The manufacturing method of the modified zinc complex in the embodiments of the present invention is as follows Step S1 of adding lysine and potassium chloride to deionized water and stirring uniformly Step S2 of adding quercetin and stirring to obtain a mixed solution Step S3 of adding zinc oxalate to the mixed solution, reacting under ultrasonic waves for 2 min, and then centrifuging and drying to obtain a modified zinc complex, including Here, zinc ion:lysine:potassium chloride:quercetin = 2:1:1:1, m / m / m / m.

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

[0028] [Table 1]

[0029] The manufacturing methods for Examples 1 to 4 are as follows: Step L1 involves adding zinc ricinoleate and nuclease to deionized water in the above mass fractions and stirring, then adding the modified zinc complex to obtain solution 1, and then adding monoethanolamine, aqueous sodium hydroxide solution, glycerin, propylene glycol, alkylbenzene sulfonic acid, ethoxylated aliphatic alcohol sulfate, aliphatic alcohol polyoxyethylene ether, saturated fatty acid, oleic acid, and essence to the reaction vessel and stirring uniformly to obtain solution 2. The method includes step L2, which involves adding solution 1 to solution 2 and stirring uniformly to obtain a super-concentrated liquid detergent composition for deodorization.

[0030] Comparative Examples 1 to 3 were established based on Example 1. The difference between Comparative Examples 1 to 3 and Example 1 is that the modified zinc complex is replaced with zinc lysine, quercetin-zinc complex, or zinc ricinoleate, respectively, while the other components and manufacturing method are the same as in Example 1.

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

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

[0033] Test Example 1: Stability Test of Detergent Composition

[0034] The testing method is as follows:

[0035] Low-temperature stability test: The detergent compositions were individually bottled and sealed. They were then placed in an environment with a temperature of -0±2°C and left at a constant temperature for 2 months. After removal, their condition was observed immediately. If there was no significant discoloration, phase separation, or precipitation in the detergent composition, it was determined to have passed the low-temperature stability test.

[0036] Constant Temperature and Humidity Stability Test: The detergent composition was sealed in a bottle and placed in an environment with a temperature of 37±2°C and a humidity of 75%. After being left at constant temperature for two months, the condition was observed immediately after removal. 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: The detergent composition was bottled and sealed, then placed in an environment with a temperature of 25±2℃ and left at constant temperature for 2 months. After removal, the condition was observed immediately. 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: After filling bottles with the detergent composition and sealing them, the bottles were placed in an environment of 45±2℃ and left at a constant temperature for 2 months. The condition was then observed immediately after removal. If there was no significant discoloration, phase separation, or precipitation in the detergent composition, 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 is clear from Table 2, the detergent compositions prepared in Examples 1-4 passed the stability test even after being left at different temperatures for two months. However, in Comparative Examples 1-2, because the modified zinc complex was replaced, a stable core-shell structure could not be formed, and precipitation or sedimentation was observed depending on the surfactant content at different temperatures. In Comparative Example 3, zinc ricinoleate was not included, and only the modified zinc complex was added, and precipitation was also observed in that sample during testing.

[0042] Test Example 2: Decontamination Performance Test of a Cleaning Agent Composition

[0043] The decontamination performance was tested according to "GB / T 13174 2008 Measurement of Decontamination Power and Circulation Washing Performance of Laundry Detergents." The results are shown in Table 3. Here, the P value represents the decontamination ratio. Generally, a standard laundry solution is used as a reference sample, with its decontamination ratio set to 1.00, and a higher P value indicates better cleaning power.

[0044] [Table 3]

[0045] As is clear from Table 3, the detergent compositions of Examples 1-4 showed significantly superior decontamination effects against carbon black, protein, and sebum compared to Comparative Examples 1-3 and the standard laundry solution. Surprisingly, Comparative Example 3 showed better protein and sebum decontamination capabilities than Comparative Examples 1-2. This suggests that the amino acids in the denatured zinc complex form a synergistic effect with phosphodiesterase, exerting a decomposition effect on three substances: metabolic sugars, sebum, and protein, resulting in a remarkable decontamination effect of the composition against protein and sebum.

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

[0047] Test Method: 1. Two identical 10cm x 10cm pieces of sweaty cotton fabric (sweet T-shirts, manufactured by the China Daily Chemicals Research Institute) were prepared and weighed before washing. 2. 1000g of tap water was added to a tray of appropriate size, and then 2.00g of ordinary laundry solution was added. 3. The weighed sweaty cotton fabrics were placed in the tray and soaked for 2 minutes, rubbed 30 times on each side, then wrung out to control the moisture content to within 150%~160%. 4. The fabrics were rinsed twice in 1L of tap water, rubbed 30 times on each side, wrung out to control the moisture content to within 150%~160%, and finally air-dried. 5. The deodorizing effect of the washed and dried sweaty cotton fabrics was evaluated.

[0048] Deodorization Results and Judgment: Ten evaluators were selected to evaluate the odor of fabrics washed with test samples. Using the odor (sweat smell) of the fabric before washing as a baseline, the degree to which the odor (sweat smell) remained in the fabric after washing was judged, and the fabric after washing was scored. The fabric after washing was divided into damp smell (smelled before drying) and dry smell (smelled after drying), and the scoring level was divided into three stages on a maximum of 50 points: 0-10 points indicates basically no odor, 10-30 points indicates a slight odor, and 30-50 points indicates a clear odor. If the average score was between 0 and 10 points, the sample could be judged as having "effectively removed the odor (sweat smell)."

[0049] The deodorizing effect was evaluated at three different time points: immediately after washing the cotton fabric (time point 1), after the cotton fabric had dried (time point 2), and after storing the cotton fabric in a sealed bag for two weeks (time point 3). The evaluators assessed the deodorizing effect at each of these three time points. The final test result is the average of the scores.

[0050] [Table 4]

[0051] According to the deodorization test results shown in Table 4, the detergent compositions of Examples 1 to 4 were found to not only remove unpleasant odors but also to suppress the recurrence of unpleasant odors during sealed storage. The amino acids and halides added to the modified zinc complex exhibit catalytic activity on the nuclease while ensuring the activity of the nuclease in a highly surfactant environment. On the other hand, Comparative Examples 1 to 3 had difficulty forming a stable crosslinked structure, and the nuclease was inhibited in a highly surfactant environment. The configuration of the modified zinc complex, zinc ricinoleate, and nuclease in the present invention acts on multiple odor molecules such as hydrogen sulfide, mercaptan, thioether, formaldehyde, isovaleric acid, and ammonia, fundamentally removing unpleasant odors and preventing their recurrence.

[0052] Test Example 4: Test of the collar cleaning ability of a detergent composition.

[0053] Test method: Two identical cotton fabrics (sweet-smelling T-shirts, manufactured by the China Daily Chemicals Research Institute) were placed in a sealed bag and aged in a 45-degree oven for 2 hours. They were then placed in a pulsator washing machine, 10g of ultra-concentrated laundry solution was added, and they were washed on a mixed wash cycle. After drying, they were evaluated.

[0054] Results and Judgment: Ten evaluators were selected to evaluate the yellowing of the collars of T-shirts after washing test samples. A T-shirt without yellowing was used as a baseline to judge the degree of yellowing on the collars of the T-shirts after washing. The yellowing on the collars of the T-shirts was scored, with a maximum score of 5 points, divided into three levels: 0-2 points for no yellowing at all, 1-3 points for slight yellowing, and 3-5 points for clear yellowing. If more than 80% of the evaluators rated that there was no remaining yellowing, the sample was judged to have "effectively removed the yellowing." The final test results are all average scores.

[0055] [Table 5]

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

[0057] The present invention is not limited to the details of the exemplary embodiments described above, and it will be apparent to those skilled in the art that it can be realized in other specific forms without departing from the spirit or basic features of the invention. Therefore, in any respect, the embodiments are illustrative and non-limiting. The scope of the invention is limited not by the above description but by the appended claims, and all modifications within the meaning and scope of equivalents of the claims are intended to be incorporated into the invention.

[0058] Although this specification describes embodiments, each embodiment does not necessarily consist of only one independent technical means. This method of description is merely for clarity, and those skilled in the art should consider the specification as a whole, and the technical means in each embodiment may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.
