Description

Technical Field

[0001] This invention belongs to the field of chemical production and relates to a brushless foam cleaner that can quickly remove a variety of stubborn stains. Background Technology

[0002] In modern homes, hotels, public swimming pools, and public restrooms, the toilets, urinals, washbasins, bathtubs, swimming pool surfaces, walls, and floors are mostly made of ceramic or glass. Stubborn stains are difficult to clean, even with steel wool, coarse brushes, or even blades. Discoloration and mold growth on floor tiles, wall tiles, and grout lines are particularly difficult to remove. Currently, these stubborn stains are typically cleaned with sanitary ware cleaners.

[0003] Sanitary ware cleaners currently come in two main types: solid and liquid. Solid cleaners, such as toilet bowl blocks, are typically neutral or weakly alkaline. While convenient to use and providing long-term effective protection for toilets, their cleaning power is limited. Liquid cleaners include acidic and alkaline formulations. Acidic formulations often use hydrochloric acid, phosphoric acid, and other moderately strong inorganic acids as main ingredients. They have strong cleaning power against stubborn stains on old toilet bowl walls, but these products have a pungent odor, and most fragrances are unstable, leading to unpleasant user experiences. They also have a certain degree of corrosiveness to metal parts and the cement components that bind to floor tiles. Formulas using organic acids, such as citric acid, oxalic acid, and sulfamic acid, are milder and can contain a wider variety of fragrances, but their cleaning power is weaker and cannot fully meet the cleaning and sterilization needs of sanitary ware. Alkaline formulations use sodium hypochlorite as the main ingredient, offering better cleaning and sterilization effects. Through the synergistic effect of surfactants, they improve adhesion, allowing the product to remain on the surface of the sanitary ware and adhere to the dirt, enhancing the cleaning effect. However, due to the product's spreadability, it spreads quickly on the surface of the toilet after application. It has a short working time for deep, stubborn stains and mold, and cannot completely remove these stubborn stains and mold, thus failing to completely eliminate the comprehensive pollution problems on the toilet surface and the surrounding environment.

[0004] Therefore, developing a toilet cleaning product that can efficiently clean various stains on sanitary wares, eliminate deep stains and disinfect, while also being convenient and safe to use, has become a pressing technical challenge. This new type of toilet cleaning product should not only quickly remove stains from sanitary wares but also effectively remove stains from toilet seat crevices, as well as stains on bathroom walls, floors, and glass areas. It should also possess good environmental friendliness and stability, maintaining effective cleaning and disinfection under various environmental conditions. Summary of the Invention

[0005] In some embodiments, the present invention provides a cleaning composition comprising the following components in parts by weight: 3-40 parts hypochlorite, 0.1-5 parts pH adjuster, 0.1-8 parts available chlorine stabilizer, 1-25 parts foaming agent, 0.5-10 parts foam stabilizer, and 0.01-5 parts penetrant; wherein the foaming agent is sodium secondary alkyl sulfonate, the foam stabilizer is dodecyl dimethyl betaine, and the penetrant is N-methylpyrrolidone.

[0006] In some embodiments, the cleaning composition comprises the following components in parts by weight: 4-25 parts hypochlorite, 0.1-3 parts pH adjuster, 0.1-5 parts available chlorine stabilizer, 1-20 parts foaming agent, 1-8 parts foam stabilizer, and 0.01-4 parts penetrant.

[0007] In some embodiments, the cleaning agent comprises the following components in parts by weight: 5-22 parts hypochlorite, 0.1-2 parts pH adjuster, 0.5-3 parts available chlorine stabilizer, 1-18 parts foaming agent, 2-7 parts foam stabilizer, and 0.06-1 parts penetrant.

[0008] In some embodiments, the cleaning agent comprises the following components in parts by weight: 5-20 parts hypochlorite, 0.5-2 parts pH adjuster, 0.5-2 parts available chlorine stabilizer, 5-15 parts foaming agent, 3-6 parts foam stabilizer, and 0.06-0.5 parts penetrant.

[0009] In some embodiments, the hypochlorite is selected from one or more of sodium hypochlorite, potassium hypochlorite, and calcium hypochlorite.

[0010] In some embodiments, the effective chlorine stabilizer is an organophosphonate, an organic carboxylate, a glycoside, or an inorganic polyphosphate.

[0011] In some embodiments, the selected effective chlorine stabilizer is selected from one or more of the following: tetrasodium aminotrimethylphosphonate, pentasodium aminotrimethylphosphonate, sodium hydroxyethylidene diphosphonate, disodium hydroxyethylidene diphosphonate, tetrasodium hydroxyethylidene diphosphonate, pentasodium ethylenediaminetetramethylphosphonate, pentasodium diethylenetriaminepentamethylphosphonate, tetrasodium ethylenediaminetetraacetate, calcium gluconate, potassium citrate, sodium pyrophosphate, pentasodium diethylenetriaminepentaacetate, trisodium hydroxyethylethylenediaminetriacetate, sodium gluconate, sodium hypochlorous acid, and sodium metasilicate.

[0012] In some embodiments, the pH adjuster is selected from acidic or alkaline adjusters.

[0013] In some embodiments, the acidity regulator is selected from one or more of citric acid, oxalic acid, formic acid, and lactic acid.

[0014] In some embodiments, the alkalinity regulator is one or more of potassium hydroxide, sodium hydroxide, triethanolamine, and monoethanolamine.

[0015] In some embodiments, the cleaning composition also includes water.

[0016] In some embodiments, the water is in the form of 45 to 90 parts by weight.

[0017] In some embodiments, the water is in the form of 50 to 85 parts by weight.

[0018] In some embodiments, the water is in the form of 50 to 80 parts by weight.

[0019] In some embodiments, the types of foaming agents, foam stabilizers, and penetrants in the cleaning compositions provided by this invention have a crucial impact on the detergency of the cleaning compositions. For example, in some embodiments, replacing the foaming agent from SAS to AOS results in a decrease in foam persistence (20 min) from 41 mm to 27 mm in a 30-day stability test at 45°C; and a significant decrease in detergency rate from 90.4% to 76.5%. Similarly, in some embodiments, replacing the foam stabilizer BS-12 with CAPO also results in a decrease in detergency rate from 91.8% to 84.3%. Furthermore, even with SAS as the foaming agent and BS-12 as the foam stabilizer, replacing the penetrant NMP with JFC-2 also results in a decrease in detergency rate from 95.5% to 82.3%. The cleaning compositions of this invention can achieve a detergency rate of over 90%, significantly higher than the 84.6% detergency rate of commercially available samples. As is well known, cleaning indoor appliances is a necessity for every household or related establishment. In particular, stains on sanitary ware, gaskets, and toilet seat crevices are often very difficult to remove. The cleaning composition of this invention has such a high stain removal rate, which will undoubtedly greatly solve the comprehensive pollution problem of toilet surface and surrounding environment, and provide people with a more comfortable and hygienic environment.

[0020] In some embodiments, the inventors also discovered that, in addition to the types of foaming agents, foam stabilizers, and penetrants having a significant impact on the detergency of the cleaning composition, the amount of NMP also has a significant impact on the detergency of the cleaning composition. For example, reducing the NMP content in Example 5 from 0.1% w / w to 0.05% w / w in Comparative Example 6 results in a decrease in the detergency rate after 30 days of stability at 45°C from 93.2% to 79.1%, indicating a significant weakening of the detergency. In other words, the NMP content cannot be too low, as this will affect its detergency. Furthermore, a higher NMP content is not always better. For instance, the NMP content in Example 3 was 0.3% w / w; when this content was increased to 1% w / w in Example 1, its detergency decreased from 90.4% to 86.5%. Therefore, the cleaning composition of the present invention is a whole, and its effectiveness depends on the combined effect of multiple factors. The specific combination obtained by the present invention achieves a very desirable effect.

[0021] In some embodiments, the cleaning composition further includes auxiliary ingredients; said auxiliary ingredients include fragrances or polymer additives.

[0084] III. Performance Testing of New No-Brush Toilet Cleaning Foam Products 1. Testing Method 1.1 Foam Durability The sample and the control sample were sprayed into tall beakers using the same spray gun, and the immediate foam height and the foam height after standing for 20 minutes were measured respectively.

[0085] 1.2 Bubble Liquidity The sample and control sample were sprayed onto the vertically placed tile using the same spray gun at a distance of 40cm, and the time it took for the foam to flow 30cm was measured.

[0086] 1.3 Product decontamination rate (1) Preparation of dirt Prepare the artificial urine stain according to the following formula. Pour 3g of stain into a plate with a base diameter of 10cm and a weight of m1 (accurate to 0.0001g). Dry and age in an oven at 60℃ for 24 hours, then dry in an oven at 105℃ for 1 hour. Weigh the stain plus the weight of the plate, m2 (accurate to 0.0001g).

[0087] (2) Decontamination rate determination Add 5g of sample toilet cleaner to the dirt tray, let it soak for 5 minutes, then rinse the tray with tap water from a height of 15cm for 5 seconds, drain the tray and put it in a 105℃ oven to dry until constant weight, and weigh it as m3 (accurate to 0.0001g).

[0088] (3) Calculation of decontamination rate .

[0089] (4) Artificial urine stain formula Raw material name and dosage, g / L Urea 20.0 Baking soda 10.0 Anhydrous calcium chloride 1.6 Magnesium sulfate hexahydrate 2.0 Sodium fatty acids 1.4 Water balance 1.4 Toilet Cleaning Foam Stability Test The experimental and control samples were placed in a 45℃ oven for 30 days, and after being removed and allowed to return to room temperature, the effective chlorine content was tested.

[0090] The available chlorine content was determined according to Chapter 19, "Determination of Available Chlorine Content in Detergents (Titration Method)," of GB / T 13173-2021 Test Methods for Surfactants and Detergents.

[0091] 2. Test Results The performance test results of the examples and comparative examples (including samples prepared at room temperature and samples after 45°C for 30 days) are shown in Table 2 below: Table 2

[0092] The differences in detergency data between Examples 1-3 and Comparative Examples 1-3 were analyzed using T.Test one-tailed analysis. The results are shown in Tables 3 and 4 below.

[0093] Table 3 (Samples prepared at room temperature)

[0094] Table 4 (Samples after 30 days at 45℃)

[0095] In the samples prepared at room temperature, the p-value of detergency between Examples 1-3 and Comparative Examples 1-3 was <0.05, indicating a significant difference. Similarly, in the samples placed at 45 degrees Celsius for 30 days, the p-value of detergency between Examples 1-3 and Comparative Examples 1-3 was <0.05, indicating a significant difference between the two groups of data.

[0096] Based on the foam characteristics and detergency test results of Sample 1 and Comparative Sample 1, the combination of SAS with BS-12 and NMP exhibits better foam performance and detergency. The differences in foam performance and detergency between Sample 2 and Comparative Sample 2, and between Sample 3 and Comparative Sample 3, also indicate that SAS, BS-12, and NMP are key to foam performance and detergency, and are indispensable factors in this invention.

[0097] The stability results at 45℃ for 30 days show that the overall decrease in available chlorine between Samples 1-3 and Control Samples 1-3 is not significantly different. Both polyhydroxyphosphonates contribute to improving the stability of available chlorine, and the strong chelating effect of EDTMPS.5Na on metal ions is more effective in stabilizing available chlorine. Furthermore, the foam performance stability of the surfactants SAS and BS-12 further contributes to maintaining the detergency rate, ensuring that the product has a basically the same detergency rate throughout its shelf life. This further demonstrates the importance of SAS, BS-12, and NMP for brushless toilet cleaning foam products. Moreover, the comparative tests between Examples 1 and 3 also show that in the compound system of this invention, the lower the NMP content, the more significant the improvement in product performance.

[0104] III. Performance Testing of New No-Brush Toilet Cleaning Foam Products The testing method was the same as in Examples 1-3, and the results are shown in Table 6.

[0105] Table 6

[0106] Test single-tail analysis showed the difference between the detergency data of Examples 3-5 and Comparative Examples 4-6. The results are shown in Tables 7 and 8.

[0107] Table 7 (Samples prepared at room temperature)

[0108] Table 8 (Samples after 30 days at 45℃)

[0109] The p-value of detergency between Examples 3-5 and Comparative Examples 4-6 was <0.05, indicating a significant difference. Similarly, the p-value of detergency between Examples 3-5 and Comparative Examples 4-6 after being placed at 45 degrees for 30 days was <0.01, indicating a significant difference between the two sets of data.

[0110] Table 6 shows the foaming performance and detergency of the formulations in Examples 3-5 and Comparative Examples 4-6 before and after stability testing. From the test results of Example 3 and Comparative Example 4, and Example 4 and Comparative Example 5, it can be seen that the combination of SAS and BS-12 is important for the detergency and foaming performance of the formulation. The test results of Example 5 and Comparative Example 6, and Example 3 and Example 5, show the relationship between NMP dosage and detergency and foaming performance in the SAS and BS-12 combination system. This further demonstrates that the combination of SAS and BS-12 with NMP exhibits good stability, durable foaming performance, and excellent detergency.

[0129] Table 14

[0130] The test results of Examples 7 and 8 demonstrate the importance of adding NMP to the SAS-BS-12 formulation for its detergency and foaming properties. In a comparison with commercially available products, Example 8, which uses SAS, BS-12, and NMP, exhibits significantly better foam flowability and stain removal efficiency than commercially available toilet cleaners.

There are black mold spots under the sealant strip. Spray both the experimental sample 7 and the commercially available sample onto the black sealant strip. After standing for 1 hour, rinse with water. The mold spots under the sealant treated with experimental sample 7 were significantly reduced and the sealant strip was basically restored to its original color. The mold spots under the sealant strip treated with the commercially available sample were slightly reduced.

[0132] In the above embodiments, the decontamination rate of the prepared product and the stability sample were both above 90%, and the entire decontamination process only used foam covering and water rinsing, indicating that the present invention can achieve brush-free and non-destructive cleaning.

[0133] The embodiments described in this invention are merely illustrative examples and are not intended to limit the implementation of this invention. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of this invention should be considered equivalent substitutions and should fall within the protection scope of this invention.
