Description

Technical Field

[0001] The present invention belongs to the technical field of washing, and particularly relates to an antibacterial and acaricidal laundry detergent and its preparation method and application. Background Art

[0002] As a commonly used household washing product, laundry detergent is increasingly favored by people. Compared with traditional washing products such as soap and washing powder, laundry detergent has a higher technical content and better detergency. At the same time, various active ingredients it contains make the clothes fluffy, soft, smooth and shiny after washing. With the continuous improvement of living standards, people have increasingly strict requirements for the home environment. The hygiene of bedding and home textiles is getting more and more attention, and higher requirements are also put forward for washing products, achieving the effect of antibacterial and acaricidal while removing stains.

The antibacterial and acaricidal laundry detergent of this invention includes sodium lauryl polyoxyethylene ether sulfate, cocoamidopropyl betaine, coco diethanolamide, mixed plant essential oil, papain, propylene glycol, potassium laurate, thickener, preservative, deionized water; it uses sodium lauryl polyoxyethylene ether sulfate, cocoamidopropyl betaine, and coco diethanolamide as the main components, and adds a self-made mixed plant essential oil. Through the synergy of components and the optimization of dosage, the antibacterial and acaricidal laundry detergent has the characteristics of super strong detergency, good antibacterial effect, and rich acaricidal function. The antibacterial and acaricidal laundry detergent has a greater detergency for carbon black oil-stained cloth, protein-stained cloth, and sebum-stained cloth than the standard laundry detergent, and the bactericidal rate for Escherichia coli and Staphylococcus aureus reaches 99%, and the acaricidal rate reaches 91.75% - 95.47%.

[0004] CN113999732A discloses an acaricidal and antibacterial laundry detergent and its preparation method. The acaricidal and antibacterial laundry detergent is composed of the following components: Platycladus orientalis water, sodium lauryl polyether sulfate, cocoamidopropyl betaine, cocoamide DEA, sodium chloride, sodium citrate, cocoamidopropyl PG-dimethyl ammonium chloride phosphate, fatty alcohol polyoxyethylene ether, sodium dodecylbenzenesulfonate, sodium bisulfite, sodium lauryl sulfate, Platycladus orientalis extract, and disodium EDTA; this invention is composed of a variety of surfactants, skin conditioners, and bactericides, which can effectively inhibit and kill Staphylococcus and Escherichia coli, and at the same time has a super strong acaricidal effect.

[0135]

[0136] The data in Table 2 show that the laundry detergent prepared by the present invention has excellent antibacterial effects. At the same time, the data in Table 2 also show that there is a synergistic effect between the plant extract and the double-chain quaternary ammonium salt in the antibacterial and acaricidal components, which has a synergistic effect in antibacterial aspects.

[0137] Test Example 3: Acaricidal performance test

[0138] Test object: The antibacterial and acaricidal laundry detergents prepared in Examples 1-11 and Comparative Examples 1-2.

[0139] Test method: According to GB / T24253 "Evaluation of the acaricidal performance of textiles", the sample laundry detergent was diluted 50 times with water, and a cotton cloth piece was immersed for 20 minutes, taken out and dried, and the acaricidal and acarostatic performances of the test sample were tested. The results are shown in Table 3.

[0140] Table 3

[0141]

[0142]

[0143] The data in Table 3 show that the laundry detergent prepared by the present invention has good acaricidal effects. Among them, the plant acaricide has a greater impact on the acaricidal effect of the laundry detergent, and the selection of the types of plant extract and double-chain quaternary ammonium salt also affects the acaricidal effect.

[0145] Test object: The antibacterial and acaricidal laundry detergents prepared in Examples 1-14.

[0146] Test method: The testers hand-washed the clothes for 15 minutes with an aqueous solution mixed with 0.3% of the laundry detergents prepared in Examples 1-14 respectively, and collected the evaluation data of the testers on irritation.

[0147] Test results: For each group of 10 testers, after using the laundry detergents prepared in Examples 1-14 to hand-wash the clothes respectively, the average evaluation score of the 10 testers on the irritation of the laundry detergent was calculated (3 no irritation, 2 slight irritation, 1 strongest irritation), as shown in Table 4.
