Description

Technical Field

[0001] This invention belongs to the field of cleaning agent technology, specifically relating to a method for preparing an enzymatically hydrolyzed floor cleaner that removes stains without leaving watermarks. Background Technology

[0002] As residents' living standards improve, the cleaning and maintenance needs of flooring, as a core element of interior decoration, are becoming increasingly sophisticated. The market's core demands for floor cleaning products have evolved from basic stain removal to diversified standards that include rapid stain removal, no residue, no watermarks, and material compatibility. Currently, mainstream flooring materials include solid wood, engineered wood, ceramic tiles, and marble. Different materials have stringent requirements regarding the pH value, irritation level, and residue levels of cleaning products. Solid wood and engineered wood flooring, in particular, are not resistant to strong acids and alkalis and are prone to watermarks, loss of luster, and even corrosion and deformation due to cleaning product residue or uneven moisture evaporation.

[0003] Existing floor cleaning products are mainly divided into two categories: one is traditional alkaline or solvent-based floor cleaners, which rely on strong alkalis or organic solvents to remove stains. Although they can remove some oil stains, they have significant drawbacks: First, they have poor stain removal targeting and low efficiency in breaking down complex stains such as oil stains and starchy food residues, requiring repeated wiping and easily causing floor wear; second, strong alkalis or solvents easily remain in floor crevices, forming white scale and watermarks after drying, which are difficult to remove; third, the pH value deviates from the neutral range, and long-term use will corrode the paint film of solid wood floors and damage the adhesive layer of composite floors, and the pungent odor is obvious, which does not meet the safety and environmental protection requirements for household use.

[0004] To address the shortcomings of traditional products, enzymatic floor cleaners have gradually become a research hotspot. Enzymes possess targeted catalytic decomposition properties; lipases, amylases, and others can specifically decompose oil stains and starchy stains without the need for vigorous scrubbing. Furthermore, their formulations are easily controlled to be neutral, resulting in better compatibility. However, existing enzymatic floor cleaners still have performance bottlenecks. The core issue lies in the selection and compatibility of surfactants: most products use conventional anionic or ordinary nonionic surfactants, which, while aiding in cleaning, exhibit strong foaming properties. During rinsing, the foam dissipates slowly, requiring multiple rinses to avoid residue, increasing water consumption. Furthermore, residual foam may still leave watermarks after drying. Some surfactants have weak resistance to hard water and easily react with calcium in hard water environments. 2+ Mg 2+ These substances combine to form insoluble precipitates that adhere to the floor surface, creating scale and watermarks. Furthermore, conventional surfactants and enzymes do not have sufficient synergy, making it difficult to effectively improve the enzyme's penetration and decomposition efficiency, resulting in the cleaning speed not meeting expectations. In addition, some surfactants can damage the spatial structure of enzymes, reduce enzyme activity stability, and shorten the product's shelf life.

[0005] Therefore, developing an enzymatic cleaning solution that is highly effective in removing stains, low-foaming and easy to rinse, resistant to hard water and leaves no residue, and compatible with various flooring materials has become an urgent need in the current floor cleaning product industry and has significant market application value. Summary of the Invention

[0006] The purpose of this invention is to provide a method for preparing enzymatically hydrolyzed floor cleaning solution that leaves no watermark.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A method for preparing an enzymatically hydrolyzed floor cleaner that removes stains without leaving watermarks includes the following steps: (1) Weigh the following raw materials: lipase, amylase, cellulase, modified fatty alcohol polyoxyethylene ether, cocamidopropyl betaine, disodium EDTA, glycerol, propylene glycol, phenoxyethanol, lemon essential oil, pH adjuster, deionized water; (2) Add some deionized water to the reactor, turn on the stirring and heat up; add disodium ethylenediaminetetraacetate and propylene glycol in sequence and stir; adjust the pH of the system with pH adjuster, stir, add modified fatty alcohol polyoxyethylene ether, add cocamidopropyl betaine, stir evenly, continue to add lipase, amylase and cellulase, stir, add glycerol, add phenoxyethanol and lemon essential oil, add the remaining deionized water, stir until the system is uniform, and store in a light-proof and sealed container.

[0009] Preferably, the lipase activity is 80,000-100,000 U / g.

[0010] Preferably, the amylase activity is 60,000-80,000 U / g.

[0011] Preferably, the cellulase activity is 60,000-80,000 U / g.

[0012] Preferably, the preparation method of modified fatty alcohol polyoxyethylene ether includes the following steps: adding AEO-9 and deionized water to a three-necked flask and stirring until the system is homogeneous; adding sodium hydroxide and stirring; adding dimethyl sulfate dropwise; continuing to stir after the addition is complete; adjusting the pH; filtering to obtain modified fatty alcohol polyoxyethylene ether.

[0013] Preferably, the dropping speed is controlled at 0.5-1 g / min.

[0014] Preferably, the pH of the system is neutralized dropwise with glacial acetic acid to 6.5-7.5.

[0015] Preferably, the mass ratio of AEO-9 to dimethyl sulfate is 100:(5-8).

The product of this invention exhibits ideal stain removal and waterproofing effects on both solid wood floors and ceramic tiles, effectively solving the technical pain points of traditional floor cleaners, such as poor compatibility with different floor materials and uneven cleaning or residual marks. Through the scientific compounding of modified surfactants and cocamidopropyl betaine, along with specific ratios of lipase, amylase, and cellulase, a highly efficient stain removal system is formed. This system can quickly remove complex stains from the surfaces of both types of flooring without damaging the wood structure of solid wood floors or the glaze of ceramic tiles. Simultaneously, the precise control of additives such as glycerin and propylene glycol in the system ensures that a uniform temporary moisturizing protective layer forms on the surfaces of both types of flooring after cleaning, reducing residue during the moisture evaporation process. After drying, the surface is bright and clean, significantly improving the cleaning experience and the durability of the effect, thus meeting the daily cleaning needs of households for both types of mainstream flooring.

[0017] 2. This invention ensures effective cleaning of both solid wood and tile floors while maintaining performance stability and safety, demonstrating outstanding practical value. It maintains consistent cleaning efficiency regardless of whether cleaning the porous surface of solid wood flooring or the dense surface of tile, avoiding fluctuations in cleaning results due to material differences. Compared to traditional floor cleaners optimized for only a single material, this invention achieves efficient compatibility with two mainstream types of flooring, reducing the cost of household cleaning products and possessing broad application prospects.

[0032] Comparative Example 5 The difference between this comparative example and Example 1 is that the amount of enzymes used is different: lipase 0.1%, amylase 0.6%, and cellulase 0.05%.

[0033] Performance testing Two commonly used flooring materials in households were selected: solid wood flooring and ceramic tile. Each material was cut into 10cm×10cm samples. The surfaces were sanded, cleaned, and dried before use, ensuring that the sample surfaces were free of original stains and scratches.

[0034] (1) Decontamination speed test 1. Stain simulation: Apply 0.5g of standardized mixed stain evenly to the surface of each material sample. The formula is: 20% edible oil, 10% starch, 5% cellulose, and 65% deionized water. After stirring evenly, heat to 40℃ and keep warm for 1 hour. Cool to room temperature and apply to an area of ​​5cm×5cm. Let it stand at room temperature for 2 hours to allow the stain to adhere stably.

[0035] 2. Test Procedure: Using a standard wiping tool and a 50g cotton cloth, apply 2mL of the test sample to the stained area and wipe repeatedly at a constant pressure of 10N and a constant speed of 10cm / s. Record the time required from the start of wiping until the stain completely disappears; this is the stain removal time. Repeat the test three times for each sample on each material, and take the average of the three test results as the final stain removal time. The shorter the stain removal time, the faster the stain removal speed.

[0036] (2) Watermark-free performance test 1. Test procedure: For each material sample, spray 5 mL of test sample evenly onto the surface of the sample using a spray bottle. Wipe the entire sample surface with a dust-free mop at a uniform force of 15 N. Then place the sample in a standard environment at a temperature of 25℃ and a relative humidity of 50% for natural drying for 2 hours.

[0037] 2. Evaluation method: Using a contact angle meter, 5 test points were randomly selected on the sample surface, 2μL of deionized water was added, the contact angle was measured, and the average value was taken; the closer the contact angle is to the original contact angle of the substrate, the less watermark residue there is. Original contact angle: 75° for laminate flooring, 82° for solid wood flooring, and 68° for ceramic tile.

[0038] All tests were conducted under constant environmental conditions: temperature 25℃, relative humidity 50%, avoiding airflow and direct sunlight from affecting the test results.

[0039] The test results are shown in Table 1.

[0040] Table 1 Performance Test Results

[0041] As shown in Table 1, the floor water in Examples 1-3 has excellent stain removal efficiency and waterproofing effect on both types of flooring.

[0042] Comparative Examples 1-3 showed a significant decrease in effectiveness due to the replacement of the modified surfactant in the original formulation. The unmodified surfactant lacked targeted structural optimization and had insufficient synergy with the auxiliary surfactant, failing to effectively reduce the surface tension of the system, weakening its stain-removing ability and thus prolonging the cleaning time. The replaced surfactant was either too hydrophilic or too weak, easily leading to uneven moisture distribution during drying and increased watermark residue. Furthermore, the cleaning mechanism of the replaced surfactant was incompatible with the enzymatic hydrolysis system, failing to form a synergistic effect with the enzyme and even slightly inhibiting enzyme activity, further weakening the cleaning effect.

[0043] In Comparative Examples 4-5, with low enzyme dosages, the total enzyme activity was insufficient to fully decompose the target components in the stains, making it difficult to remove the stains quickly and resulting in a significant decrease in cleaning efficiency. Simultaneously, the enzymatic reaction was incomplete, and residual stain components combined with moisture, forming more noticeable marks after drying. While the comparative examples with high enzyme dosages showed some improvement in cleaning speed, excessive enzymes could disrupt the system's stability, causing interactions between enzyme molecules and affecting their binding efficiency with stains. Furthermore, the presence of excess enzymes did not further improve the waterproofing effect; instead, the imbalance in the system's component ratios had a slight negative impact on surface tension control. From a practical perspective, adding excess enzymes offers no real benefit and only increases formulation costs, rendering it impractical.

[0044] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
