Description

Technical Field

[0001] The present invention relates to the technical field of laundry detergents, and in particular to a decontamination laundry detergent with nano antibacterial and mite removal functions and long-lasting fragrance retention. Background Art

[0002] Human beings' pursuit of clean clothes runs through thousands of years of civilization history. Initially, people used crushed wood ash and soap beans to remove stains, or used the natural amylase in rice washing water to decompose oil stains. The "Qimin Yaoshu" of the Han Dynasty recorded that the "lime juice" boiled together with wood ash and shell ash had already begun to have the principle of alkaline decontamination. After the Industrial Revolution in the 19th century, petrochemicals gave birth to hard soaps, but the sediment caused by the high pH value and the reaction with calcium soap caused silk, cashmere and other fabrics to be repeatedly "disfigured". In the mid-20th century, the birth of synthetic surfactants completely rewrote the history of laundry - laundry detergent broke through the solubility limitations of solid soap in liquid form, and its low-temperature instant dissolution, low foaming and easy rinsing properties quickly occupied the market. As a detergent designed specifically for clothing cleaning, laundry detergent has powerful cleaning ability and multiple functions. It can not only thoroughly clean clothes, but also protect clothes and remove odors from clothes. At the same time, it is also required to be environmentally friendly. However, traditional decontamination laundry detergents often contain nanosilver, plant essential oils, etc. as antibacterial / mite removal ingredients, which are released through passive diffusion or physical adsorption. However, they only release active ingredients in the initial stage of washing, and the residual activity is insufficient, making it difficult to cover the risk of microbial breeding during the entire storage and wearing cycle of clothing. In addition, some fragrance molecules such as lily of the valley aldehyde are easily decomposed by microorganisms, resulting in rapid volatilization and short fragrance retention time. Therefore, the decontamination laundry detergent prepared by the present invention with nano-antibacterial and mite removal and long-lasting fragrance retention functions solves the technical difficulties of inefficient release of nanosilver during washing and poor fragrance retention stability. Summary of the Invention

[0003] In order to overcome the problems of inefficient release of nanosilver and poor fragrance stability of traditional decontamination laundry detergent during washing.

[0004] The technical solution of the present invention is: a decontamination laundry detergent with nano-antibacterial and mite-removing functions and long-lasting fragrance-retaining functions, comprising the following components in parts by weight: 3-10 parts of nano-carriers, 1-2 parts of tea tree essential oil, 0.8-1.5 parts of cedar essential oil, 0.5-2 parts of protease inhibitory peptides, 0.8-1.5 parts of vanillin derivatives, 6-14 parts of sodium dodecylbenzenesulfonate, 8-13 parts of α-olefin sulfonate, 6-10 parts of alkyl glycosides, 0.5-1.5 parts of alkaline-resistant protease, 0.5-1.5 parts of lipase, 2-4 parts of water quality regulator, 0.5-0.8 parts of pH buffer, 0.7-1.4 parts of thickening stabilizer and 70-80 parts of deionized water.

[0005] Preferably, the nanocarrier is pH-sensitive Zn-MOFs loaded with nanosilver, which is loaded in the Zn-MOFs pores by an in-situ reduction method and has a particle size of 10-20 nm.

[0006] Preferably, the pore size of Zn-MOFs is 15-25 nm, and the pore size is 5-10 nm larger than the particle size of nanosilver.

Secondly, a 0.1M silver nitrate solution (AgNO3) is prepared and added to a zinc-based metal organic framework (Zn-MOFs) with a mass ratio of 1:10, ultrasonically dispersed for 30 minutes, and then a reducing agent ascorbic acid (molar ratio of Ag) is added. + : ascorbic acid = 1:2), stirred at 60 ° C for 4 hours, Ag + The nanosilver particles are reduced in situ to 10-15 nm in size and centrifuged and washed with deionized water until there is no Ag. + The residue was dried to obtain the Ag@Zn-MOFs composite support.

[0008] Preferably, the water quality regulator is selected from one or more combinations of sodium citrate, sodium gluconate, sodium polyacrylate or layered sodium silicate.

[0009] Preferably, the pH buffer includes but is not limited to triethanolamine and phosphate.

[0010] Preferably, water quality regulators and pH buffers are used to chelate calcium and magnesium ions, adapt to hard water environments, maintain the system pH in the range of 7.5-8.5, and activate the acidic response characteristics of MOFs.

[0011] Preferably, the thickening stabilizer is a hydrophobically modified polyacrylate, which is used to resist electrolyte interference and maintain stable viscosity of the laundry detergent.

[0012] As preferred surfactants, sodium dodecylbenzenesulfonate, α-olefinsulfonate and alkyl polyglycoside provide excellent detergency performance.

[0013] The present invention also provides a method for preparing a decontamination laundry liquid with nano antibacterial and mite removal functions and long-lasting fragrance retention, and the preparation steps are as follows:

[0014] Step 1: Weigh and set aside according to the required proportion of the formula;

[0015] Step 2: Heat deionized water to 45°C, add water quality regulator and pH buffer, and stir to dissolve;

[0017] Step 4: Slowly add the nanocarrier, tea tree essential oil, and cedar essential oil into the system and stir for 30 minutes until evenly dispersed;

[0018] Step 5: Add the vanillin derivative in the dark, then slowly add the thickening stabilizer and stir for 40 minutes until completely swollen;

[0019] Step 6: Process the mixture through a high-pressure homogenizer three times to ensure uniform distribution of the nanocarriers and fragrance molecules, resulting in the finished laundry detergent.

[0020] Step 7: Fill into brown high-density polyethylene bottles and store.

[0021] Beneficial effects of the present invention:

[0022] This decontamination laundry detergent with nano-antibacterial and mite-removing properties and long-lasting fragrance uses pH-sensitive Zn-MOFs loaded with nanosilver as a nanocarrier. When microbial growth occurs during the washing process, the organic acids produced by bacterial metabolism cause a local pH drop. At this point, the pH-sensitive Zn-MOFs carrier dissociates, precisely releasing the nanosilver. This intelligent responsive release mechanism enables targeted release of the antimicrobial ingredients at the site of microbial growth, avoiding the ineffective loss of antimicrobial ingredients in traditional static release methods and significantly improving the antimicrobial effect. In addition to nanosilver, the formula also contains tea tree and cedar essential oils, which synergize with vanillin derivatives to slowly release fragrance molecules, imparting a long-lasting fragrance to clothing. Ultraviolet radiation for 30 minutes activates the hydrolysis of the vanillin derivatives, resulting in a sustained fragrance release of over seven days. Furthermore, a water quality regulator and pH buffer reduce water hardness, providing a stable environment and preventing water quality issues from affecting the stability of the vanillin derivatives. This laundry detergent combines efficient decontamination, targeted antibacterial and mite removal, and long-lasting fragrance, making it suitable for use in high-hygiene environments such as homes, healthcare, and maternity and baby products.
