Description

Technical Field

[0001] This invention relates to the field of laundry detergent technology, particularly to the field of IPC C11D1, and further to an antibacterial laundry detergent containing Artemisia argyi essential oil extract and its manufacturing process. Background Technology

[0002] Laundry detergent, a cleaning product whose active ingredients are mainly composed of anionic and nonionic surfactants, occupies a dominant position in the laundry market due to its near-neutral pH, gentleness on the skin, and faster degradation in nature compared to laundry powder. It is increasingly favored by young people. However, as consumer demands continue to rise, so do the requirements for laundry detergent. For example, more and more people require laundry detergent to not only remove surface dirt but also have antibacterial properties. Ordinary laundry detergents often fail to meet these health requirements, and some even cause stains removed during washing to redeposit on clothes, leading to yellowing and aging.

[0003] Chinese patent CN201810490359 discloses a highly effective antibacterial laundry detergent and its preparation method. The detergent contains the following components by weight: 15-20 parts of sodium fatty alcohol polyoxyethylene ether sulfate, 6-10 parts of sodium alkylbenzene sulfonate, 3-5 parts of fatty acid diethanolamide, 3-5 parts of hydrogen peroxide, 40-50 parts of deionized water, 3-5 parts of povidone-iodine, and 9-15 parts of compound (I). Extensive experimental verification has shown that this laundry detergent has a high antibacterial effect, superior to most existing laundry detergents; however, this technology uses chemical antibacterial methods, and its chemical components may have adverse effects on clothing. Summary of the Invention

[0004] The first aspect of this invention provides an antibacterial laundry detergent containing Artemisia argyi essential oil extract. By weight percentage, the raw materials include at least: 4-10% anionic surfactant, 2-10% nonionic surfactant, 1-3% traditional Chinese medicine ingredients, 0.2-2% Artemisia argyi essential oil extract, 0.5-3% inorganic salts, 0.1-0.5% complex protease, 0.1-0.5% citric acid, 0.2-0.6% fragrance, and purified water to make up the balance.

[0005] Preferably, the antibacterial laundry detergent, by weight percentage, comprises at least the following ingredients: 6-8% anionic surfactant, 4-8% nonionic surfactant, 1.5-2.5% traditional Chinese medicine ingredients, 0.5-1% Artemisia argyi essential oil extract, 1-2% inorganic salts, 0.1-0.3% complex protease, 0.1-0.3% citric acid, 0.3-0.5% fragrance, and the remainder is purified water.

[0006] Preferably, the antibacterial laundry detergent further comprises, by weight percentage, 2-4% of an amphoteric surfactant.

[0007] Preferably, the anionic surfactant is selected from at least one of fatty alcohol polyoxyethylene ether sulfate, alkylbenzene sulfonate, and alkyl sulfate.

[0008] Preferably, the anionic surfactant is fatty alcohol polyoxyethylene ether sulfate.

[0009] Preferably, the fatty alcohol polyoxyethylene ether sulfate is selected from fatty alcohols with a carbon chain of C10-2000. 10 -C 16 The sodium salt of fatty alcohol polyoxyethylene ether sulfate, the carbon chain of the fatty alcohol is C 10 -C 16 At least one of the following: fatty alcohol polyoxyethylene ether potassium sulfate.

[0010] Preferably, the fatty alcohol polyoxyethylene ether sulfate is a fatty alcohol with a carbon chain of C10. 10 -C 16 Sodium sulfate of fatty alcohol polyoxyethylene ether.

[0011] Preferably, the fatty alcohol polyoxyethylene ether sulfate is a fatty alcohol with a carbon chain of C10. 12 Sodium sulfate of fatty alcohol polyoxyethylene ether.

[0012] Preferably, the nonionic surfactant is selected from at least one of fatty alcohol polyoxyethylene ether, coconut oil fatty acid diethanolamide, cashew phenol polyoxyethylene ether, and fatty acid methyl ester polyoxyethylene ether.

[0013] Preferably, the nonionic surfactant is selected from a combination of fatty alcohol polyoxyethylene ether and coconut oil fatty acid diethanolamide.

[0014] Preferably, the weight ratio of the fatty alcohol polyoxyethylene ether to coconut oil fatty acid diethanolamide is (1-2):(1-2).

[0015] Preferably, the weight ratio of the fatty alcohol polyoxyethylene ether to coconut oil fatty acid diethanolamide is 1:1.

[0016] Preferably, the amphoteric surfactant is selected from at least one of cocamidopropyl betaine, dodecyl dimethyl betaine, and lauramide propylamine oxide.

[0017] Preferably, the amphoteric surfactant is cocamidopropyl betaine.

[0018] Preferably, the weight ratio of the anionic surfactant, nonionic surfactant and amphoteric surfactant is (1.5-3):(0.5-3):1.

[0019] Preferably, the weight ratio of the anionic surfactant, nonionic surfactant, and amphoteric surfactant is 2:2:1.

[0020] During the experiment, the applicant discovered that when amphoteric surfactants are added to the system of this application, that is, when the surfactant system of this application is a mixture of anionic surfactants, nonionic surfactants and amphoteric surfactants, especially when the amphoteric surfactant is cocamidopropyl betaine, the detergent's detergency can be improved, and the detergent's antibacterial and anti-redeposition properties can also be improved. The applicant hypothesizes that, in addition to the hydrophobic interaction between the hydrocarbon chains of cocamidopropyl betaine and the anionic and nonionic surfactants in the system, the positive charge of the polar group of cocamidopropyl betaine and the anionic group of the anionic surfactant exhibit electrostatic attraction, causing the surfactants to arrange themselves more tightly, thus working together to improve the detergency of the laundry detergent. Simultaneously, the compounded surfactants may also cause changes in the spatial structure of the complex protease due to the ionization of ions, forming a complex with the complex protease, thereby giving the protease a certain antibacterial effect. Furthermore, the laundry detergent system formed by the compounded surfactants can ensure the activity and stability of the herbal ingredients and Artemisia argyi essential oil extract, thus improving both the detergency and antibacterial properties of the laundry detergent; at the same time, it prevents the washed-off stains from redepositing on the clothes, resulting in good anti-redeposition properties of the laundry detergent.

[0021] The applicant further discovered that when the weight ratio of anionic surfactant, nonionic surfactant, and amphoteric surfactant is (1.5–3):(0.5–3):1, especially when the weight ratio of fatty alcohol polyoxyethylene ether and coconut oil fatty acid diethanolamide is 1:1, the enzyme activity of the laundry detergent can be improved. The applicant speculates that at this weight ratio, when the pH of the laundry detergent changes during washing, the nonionic surfactant can reduce the charge neutralization phenomenon in the system to a certain extent, maintain the stability of the laundry detergent system, and avoid the inactivation of complex proteases.

[0022] Preferably, the herbal ingredients are selected from at least one of Artemisia annua L. extract, Lonicera japonica Thunb. extract, Aloe vera (Haw.) Berg extract, and Taraxacum mongolicum extract.

[0023] Preferably, the herbal ingredient is Artemisia annua extract.

[0024] Preferably, the artemisia extract is an aqueous extract of artemisia.

[0025] Through extensive experiments, the applicant discovered that when the herbal ingredient is Artemisia annua extract, specifically an aqueous extract, it can synergistically enhance the antibacterial properties of the laundry detergent while also improving its detergency and the stability of the complex protease. The applicant hypothesizes that this is because the active ingredients in the Artemisia annua aqueous extract, such as artemisinin, artemisinin A, artemisinin B, and artemisinin C, synergistically enhance the effects of the active ingredients in the Artemisia annua essential oil extract, such as artemisinin alcohol, artemisinin A, and dextrorotatory geraniol, while also exhibiting good compatibility with the complex protease, thus maintaining its stability.

[0026] Preferably, the preparation method of the Artemisia annua water extract includes the following steps: taking Artemisia annua leaves and stems, drying and pulverizing them, sieving them through a 25-65 mesh sieve, adding water and boiling them 3-5 times, 1-2 hours each time, filtering, combining the filtrates, decolorizing them with activated carbon, and finally concentrating the filtrate until the water content is below 25-35%, thus obtaining the extract.

[0027] Preferably, the preparation method of the mugwort essential oil extract includes the following steps: soaking cleaned mugwort leaves in water for 30-40 minutes; after soaking, extracting the essential oil by steam distillation.

[0028] Preferably, the weight ratio of the mugwort leaves to water is 1:(5-15).

[0029] Preferably, ultrasonic treatment is performed every 3 to 7 minutes for 5 to 10 seconds during the soaking of Artemisia argyi leaves.

[0030] Preferably, the inorganic salt is selected from at least one of sodium chloride, ammonium chloride, and potassium chloride.

[0031] Preferably, the complex protease is selected from at least one of alkaline protease, trypsin, papain, and bromelain.

[0032] Preferably, the complex protease is a combination of alkaline protease and papain.

[0033] Preferably, the weight ratio of alkaline protease to papain is (8-10):(1-3).

[0034] Preferably, the citric acid is selected from at least one of anhydrous citric acid and citric acid monohydrate.

[0035] Preferably, the fragrance is selected from at least one of the following: mugwort fragrance, rose fragrance, peony fragrance, lily of the valley fragrance, peach fragrance, green apple fragrance, woody fragrance, powdery fragrance, and musk.

[0036] A second aspect of the present invention provides a production process for an antibacterial laundry detergent containing artemisia argyi essential oil extract, comprising the following steps:

[0037] (1) Weigh each raw material according to its weight percentage;

[0038] (2) Heat the anionic surfactant, nonionic surfactant, amphoteric surfactant and 55-65 wt% pure water to 35-45℃ and stir at 100-200 r / min for 20-30 min to obtain mixture 1;

[0039] (3) Cool the mixture 1 to 20-25℃, and adjust the pH to 6.0-8.0 with citric acid while stirring at 100-200r / min to obtain mixture 2;

[0040] (4) Add the Chinese herbal medicine ingredients, Artemisia argyi essential oil extract, compound protease, fragrance, and remaining purified water to mixture 2, and stir at 150-300 r / min for 10-20 min until the liquid is completely transparent to obtain mixture 3;

[0041] (5) Add the inorganic salt to the mixture 3 and stir at 50-100 r / min for 10-20 min until the liquid is completely transparent.

[0042] Beneficial effects:

[0043] 1. In this application, the herbal ingredient is Artemisia annua extract. When the Artemisia annua extract is an aqueous extract of Artemisia annua, it can work synergistically with the Artemisia argyi essential oil extract in this application to improve the antibacterial properties of the laundry detergent, as well as its cleaning properties and the stability of the complex protease.

[0044] 2. The surfactant system of this application is a compound of anionic surfactants, nonionic surfactants and amphoteric surfactants. In particular, when the amphoteric surfactant is cocamidopropyl betaine, it can improve the detergency of the laundry detergent while also improving the antibacterial and anti-redeposition properties of the laundry detergent.

[0045] 3. In this application, when the weight ratio of anionic surfactant, nonionic surfactant and amphoteric surfactant is (1.5-3):(0.5-3):1, especially when the weight ratio of fatty alcohol polyoxyethylene ether and coconut oil fatty acid diethanolamide is 1:1, the enzyme activity of the laundry detergent can be improved.

[0046] 4. This application improves the detergent's cleaning power and antibacterial properties by adding 1-2% inorganic salt by weight.

[0047] 5. This application controls the steps and stirring speed in the production process of laundry detergent, which further improves the stability of the complex protease in the laundry detergent, thereby improving the detergent's cleaning power. Detailed Implementation
