Description

Technical Field

[0001] This invention belongs to the field of detergent cleaning, specifically, it relates to an anti-mildew and antibacterial detergent composition and its application. Background Technology

[0002] There are many existing laundry detergents, but during their research and development, most are designed for single molds such as Aspergillus niger, with weak inhibitory effects on other common molds such as Penicillium and Aspergillus flavus. Their anti-mold rating is mostly level 2, but due to the 10%-30% wet growth area, they cannot meet the needs of rainy seasons or high-humidity environments. Their antibacterial rate is low and short-lived: the antibacterial rate against Escherichia coli and Staphylococcus aureus is mostly below 90%, and they lack a long-lasting mechanism. After 7 days of storage, the antibacterial rate drops below 50%, making it easy for bacteria to re-grow. Anti-mold agents such as ZPT are prone to precipitation reactions with surfactants, especially anionic ones, leading to the loss of active ingredients. After 3 months of storage, the anti-mold effect decreases by more than 40%.

[0003] Meanwhile, most existing laundry detergents are alkaline formulas with a pH value of 8.0-9.5 and lack buffering systems. This leads to significant pH fluctuations during washing, which can easily damage the skin barrier or cause colored clothing to fade. Some products contain fragrances, formaldehyde-releasing preservatives such as DMDM ​​hydantoin, and allergen residues, posing a risk of sensitization with long-term use and failing to meet the stringent requirements of EU regulations such as EC1223 / 2009.

[0004] Therefore, existing detergent technologies are limited by problems such as unreasonable ingredient formulation, insufficient functional synergy, and poor adaptability to different scenarios, making it difficult to simultaneously meet the comprehensive requirements of long-lasting anti-mildew and antibacterial effects, mild and low-irritation properties, and stable and residue-free performance.

Detailed Implementation

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The present invention will be described in detail with reference to the following embodiments: Example 1

[0020] An anti-mildew and antibacterial detergent composition, calculated by weight percentage, comprises: 10-15 parts of sodium dodecylbenzenesulfonate 5-8 parts of fatty alcohol polyoxyethylene ether 3-5 parts of cocamidopropyl betaine Zinc pyrithione 0.5-1 part Nano silver antibacterial agent 0.1-0.3 parts 1-2 parts tea tree oil extract 0.5-1 part of disodium EDTA 2-3 parts polyethylene glycol 1-2 parts of dioctadecyl dimethyl ammonium chloride Citric acid 0.3-0.5 parts Phenoxyethanol 0.5-1 part 0.2-0.5 parts of polydimethylsiloxane Deionized water balance.

[0021] In the above formula, the anti-mold and antibacterial effects are designed with a three-layer protective structure: targeted anti-mold, broad-spectrum antibacterial, and natural soothing.

[0022] Firstly, by specifically inhibiting Aspergillus niger and Penicillium spores commonly found in clothing storage using zinc pyrithione (ZPT), the problem of clothing mold growth during the rainy season is solved. Secondly, the nano-silver antibacterial agent we selected covers bacteria such as Escherichia coli, Staphylococcus aureus, and fungi, achieving antibacterial activity in all scenarios. Furthermore, tea tree oil extract helps to inhibit bacteria, while natural ingredients reduce the irritation of chemicals to the skin.

[0023] Compared to single preservative formulations, such as using only phenoxyethanol, this design extends the anti-mold period from 1 month to 3 months, increases the antibacterial rate from 90% to 99.9%, and leaves no chemical residue or odor.

[0024] Our invention employs a ternary compound system of anionic, nonionic, and amphoteric surfactants in its surfactant formulation. The anionic surfactant used is sodium dodecylbenzene sulfonate, which is highly effective at removing water-based stains such as sweat stains and juice residue. Nonionic surfactants using fatty alcohol polyoxyethylene ethers enhance oily stains, such as engine oil and chili oil, providing strong emulsification capabilities. In particular, the use of fatty alcohol polyoxyethylene ethers can maintain a stable stain removal effect at low temperatures. The amphoteric surfactant uses cocamidopropyl betaine, which effectively reduces the irritation of anionic surfactants while improving compatibility with sensitive fabrics such as wool and silk. Compared to existing single-anionic formulations, such as those using only sodium dodecylbenzenesulfonate surfactant, this design expands the stain removal range by 30%, increases the removal rate of oily stains from 75% to 98%, and verifies a 50% reduction in skin irritation through human patch testing.

[0025] This formula contains no fragrances or colorants, thus fundamentally avoiding chemical allergens. At the same time, citric acid is used to adjust the pH to neutral (7.0), which is close to the skin's pH, reducing acid and alkali irritation. The use of amphoteric surfactants CAB to replace some anions can reduce the damage of surfactants to the skin barrier. Example 2

[0026] An anti-mildew and antibacterial detergent composition, calculated by weight percentage, comprises: 12 parts of sodium dodecylbenzenesulfonate 6 parts fatty alcohol polyoxyethylene ether 4 parts of cocamidopropyl betaine 0.8 parts of zinc pyrithione 0.2 parts of nano silver antibacterial agent 1.5 parts tea tree oil extract 0.8 parts of disodium EDTA 2.5 parts polyethylene glycol 1.5 parts of dioctadecyl dimethyl ammonium chloride Citric acid 0.4 parts 0.8 parts of phenoxyethanol 0.3 parts of polydimethylsiloxane Deionized water balance.

[0027] In this embodiment, we optimized the optimal mass ratio to achieve anti-mold and antibacterial effects. Simultaneously, through precise ingredient ratio design, we achieved comprehensive functions including universal stain removal, anti-mold and antibacterial properties, hypoallergenic effects, wrinkle resistance, and residue-free performance. Compared to existing technologies, this represents a significant improvement in gentleness, multi-functional integration, and long-lasting effectiveness, making it widely applicable to various washing scenarios.

[0028] Specifically, among the surfactants selected in this embodiment: sodium dodecylbenzenesulfonate, which can balance detergency and rinsing properties; fatty alcohol polyoxyethylene ether, which enhances the emulsification of oily stains, such as sebum / edible oil; and cocamidopropyl betaine, which reduces LAS irritation and improves mildness.

[0029] The antifungal and antibacterial agent uses zinc pyrithione to achieve long-lasting antifungal effect, nano-silver antibacterial agent for synergistic antibacterial effect, and tea tree oil extract for natural soothing, which can reduce chemical irritation. The antifungal effect can reach ≥3 months, and the bacterial killing rate of nano-silver antibacterial agent is ≥99.9%.

[0030] Regarding functional additives, we selected disodium EDTA, which can completely chelate calcium and magnesium ions to prevent residues; polyethylene glycol (PEG-400) and softener synergistically enhance the anti-wrinkle effect; bis(octadecyl)dimethylammonium chloride can prevent precipitation with anionic surfactants; and citric acid can stabilize the pH of the composition to the mildest range, i.e., pH 7.0.

[0031] In selecting preservatives and defoamers, this formula uses phenoxyethanol, which provides both preservative and anti-mildew properties. Polydimethylsiloxane controls foam height to ≤3cm, making it suitable for both hand and machine washing.

[0032] Deionized water is better able to ensure the uniform dispersion of various materials in the formulation during the preparation of ingredients than ordinary water, and it can also be used to blend various ingredients.

[0033] To more accurately illustrate the anti-mold and antibacterial effects described in this formula, we will use the following test methods.

[0034] Regarding the evaluation and measurement of anti-mildew performance, we achieve this by verifying the inhibitory effect and long-term effectiveness against common molds on clothing.

[0035] For strain selection, we used common molds found in clothing storage, such as Aspergillus niger, Aspergillus terreus, and Penicillium. During the test, the detergent solution was diluted 1:100 and mixed with the mold spore suspension. This mixture was then inoculated onto agar medium. After 72 hours of incubation, the diameter of the inhibition zone was measured. An inhibition zone diameter ≥15 mm was considered effective; in our tests, the inhibition zone diameter was 20-15 mm.

[0036] Standard cotton fabrics were treated with detergent in a manner that simulated normal washing, and simultaneously inoculated with mold spores. The fabrics were then cultured for 28 days at 28°C and 95% relative humidity.

[0037] 1. Rating based on the area of ​​mold growth: Level 0: No growth; Level 1: Growth area < 10%, Meets the standard at level 1 or above.

[0038] 2. Mold resistance verification: The above test was repeated after the fabric was washed 5 and 10 times to evaluate the decay of the anti-mold effect. It was required that the fabric still reached level 1 after 5 washes.

[0039] The initial anti-mold level is ≥1, and the anti-mold level is ≥2 after 5 washes, with the mold growth area being <30%.

[0040] 3. Antibacterial performance evaluation: Verify the ability to inhibit pathogenic and opportunistic pathogens.

[0041] The strains selected were Escherichia coli, Staphylococcus aureus, and Candida albicans.

[0042] Dilute the detergent solution at a ratio of 1:50. After dilution, react the diluted solution with the bacterial suspension for 10 minutes and calculate the antibacterial rate. An antibacterial rate of >99.9% is required for strong antibacterial effect.

[0043] Minimum inhibitory concentration (MIC) determination: The MIC value against the target bacteria is determined by microdilution. The lower the MIC, the higher the antibacterial efficiency. The target values ​​for this formulation are: MIC ≤ 0.5% against Escherichia coli and MIC ≤ 0.8% against Staphylococcus aureus.

[0044] Validation of long-lasting antibacterial effect: After washing, the fabric was stored for 7 days, and the number of viable bacteria on the surface was tested. The requirement was that the number of bacteria should be reduced by ≥2 orders of magnitude compared with the untreated group. Through testing, the formula of this invention achieved an immediate antibacterial rate of >99.9% and a long-lasting antibacterial rate of >90% after 7 days. Example 3

[0045] An anti-mildew and antibacterial detergent composition, calculated by weight percentage, comprises: Sodium lauryl sulfate 9.0 parts Cocamidopropyl betaine 6.0 parts 8.0 parts of fatty alcohol polyoxyethylene ether 0.4 parts of disodium EDTA Citric acid 0.8 parts 6.0 parts of anhydrous sodium sulfate 2.5 parts of polyethylene glycol 2000 Capryloyl hydroxamic acid 0.3 parts 0.6 parts of phenoxyethanol Dipotassium glycyrrhizate 0.2 parts 0.2 parts of polyether-modified silicone oil Deionized water balance.

[0046] In this embodiment, we selected sodium lauryl sulfate, cocamidopropyl betaine, and fatty alcohol polyoxyethylene ether as surfactants, which can effectively remove water-based stains. Cocamidopropyl betaine can gently enhance the removal of oil-based stains and reduce irritation, while fatty alcohol polyoxyethylene ether can emulsify oil-based stains and improve low-temperature detergency.

[0047] In this embodiment, the functional additives are selected as disodium EDTA, citric acid, anhydrous sodium sulfate, and polyethylene glycol 2000. Disodium EDTA can chelate calcium and magnesium ions and soften water; citric acid can adjust the pH to slightly acidic (5.5-6.5) and prevent allergies; anhydrous sodium sulfate can enhance surfactant activity and adjust consistency; and polyethylene glycol 2000 can achieve smooth fibers and wrinkle resistance after use. These additives further improve the performance of the anti-mildew and antibacterial detergent composition.

[0048] In this embodiment, the antifungal agent is selected as capryloyl hydroxamic acid, and the antibacterial agent is selected as phenoxyethanol. Capryloyl hydroxamic acid provides broad-spectrum antifungal activity and inhibits mold spore germination, while phenoxyethanol provides antibacterial activity, targeting Gram-negative bacteria and fungi, and is a low-irritant preservative. This not only effectively achieves antifungal and antibacterial effects but also makes the composition more adaptable to market needs.

[0049] Dipotassium glycyrrhizate is an anti-allergy ingredient that can soothe the skin, reduce the risk of allergies, and enhance the user experience.

[0050] Polyether-modified silicone oil acts as a foam suppressant, which can not only control the amount of foam, making the foam of the composition moderate and easy to rinse, but also further reduce residual marks.

[0051] Regarding the selection of surfactants, we adopt a surfactant blending approach, with the total surfactant content being 20%-27%. We still use anionic, amphoteric, and nonionic blends to achieve a strong balance between detergency and gentleness.

[0052] Sodium lauryl sulfate (SLS) is used as the anionic surfactant. It has strong cleaning power for water-based stains such as sweat stains and juice stains, but it is easy to cause irritation when used alone. Therefore, the content is controlled at 8%-10%, and 9% is preferred in this embodiment.

[0053] Amphoteric surfactants can reduce the irritation of sodium lauryl sulfate (SLS) while enhancing the emulsification ability of oily stains, such as oil stains and cosmetics. In this invention, we selected cocamidopropyl betaine (CAB), and a ratio of 5%-7% can balance gentleness and detergency. In this embodiment, 6% is selected.

[0054] Nonionic surfactants can still effectively emulsify greases at low temperatures. Fatty alcohol polyoxyethylene ether (AEO-9) is preferred. In combination with other surfactants, it can improve the overall detergency range. 7%-10% ensures universality for both water-based and oil-based stains. 8% is selected in this embodiment.

[0055] By combining the above-mentioned anionic, amphoteric, and nonionic surfactants, this formula is more suitable for market demands than traditional detergents. Traditional detergents on the market mostly rely on anionic surfactants, which are weak in removing oily stains and highly irritating. For example, products that only use sodium dodecylbenzene sulfonate (LAS) as the surfactant can be used. After this formula is combined, the stain removal range is expanded by more than 30%, and the skin patch test verifies that the irritation is reduced by 50%.

[0056] The total proportion of functional additives in the overall formula is controlled at 8%-13%, and the specific ingredients are the following four.

[0057] (1) Disodium EDTA: The proportion of disodium EDTA is 0.3%-0.5%. In this embodiment, the preferred proportion is 0.4% through testing. It can effectively chelate calcium and magnesium ions in water, avoid the reaction of surfactants with hard water to form precipitates, ensure stable detergency, and solve the problem of reduced detergency of traditional detergents in hard water areas.

[0058] (2) Citric acid: Citric acid accounts for 0.5%-1.0%: Adjust the pH to 5.5-6.5 to make it close to the skin pH, which can reduce the stimulation to sensitive skin. Since mold prefers an alkaline environment, citric acid can be used to adjust the pH while inhibiting the growth of mold under alkaline conditions, thus strengthening the anti-mold effect.

[0059] (3) Anhydrous sodium sulfate: Anhydrous sodium sulfate accounts for 5%-8% of the total content: It can increase the solubility of surfactants in water and improve the cleaning efficiency. However, if the proportion is too high, it will easily cause white stains on clothes. Therefore, it should be controlled within 8%.

[0060] (4) Polyethylene glycol 2000: Polyethylene glycol 2000 accounts for 2%-3% of the total content: It adsorbs on the fiber surface to form a lubricating film, reduces friction between fibers, reduces wrinkles after washing, and solves the problem of stiff and wrinkled clothes after washing with traditional detergents.

[0061] The total proportion of antifungal and antibacterial agents in the formula is 0.7%-1.2%, of which the antifungal agent is octanoyl hydroxamic acid, with a proportion controlled at 0.2%-0.4%, replacing traditional high-irritant antifungal agents, such as formaldehyde releasers. It works by inhibiting the respiratory enzymes of mold cells, and has an inhibition rate of 99% against common clothing molds such as Aspergillus niger and Penicillium, and is non-irritating to the skin.

[0062] The antibacterial agent selected is phenoxyethanol, with a proportion controlled at 0.5%-0.8%. It has both antibacterial and preservative functions, with an antibacterial rate of >99.9% against Escherichia coli and Staphylococcus aureus. At the same time, it can replace traditional preservatives, such as parabens, and reduce the risk of allergies.

[0063] Traditional detergents often rely on a single preservative, such as Kathon, for mold and bacteria prevention, which has a narrow anti-mold spectrum and is prone to causing allergies. This invention uses a three-in-one approach of mold prevention, antibacterial, and preservative, which improves the mildness of our detergent composition by 40% compared to the milder versions of traditional detergents. It can still effectively prevent mold and bacteria after 5 washes and has a long-lasting anti-mold effect, extending the anti-mold validity period to 3-4 months.

[0064] Dipotassium glycyrrhizate accounts for 0.1%-0.3% of the total amount in the formula. Dipotassium glycyrrhizate is a plant-derived soothing ingredient that can inhibit the release of skin inflammatory factors, reduce the irritation of surfactants to sensitive skin, and solve the problem of rashes easily caused by traditional detergents.

[0065] The total proportion of polyether-modified silicone oil in the formulation is 0.1%-0.3%. The amount of foam is adjusted to a foam height of 50-80mm at 20℃ to avoid excessive foam residue. At the same time, the adsorption of the components on the fibers is reduced to ensure that there are no white marks or odors after drying.

[0066] In this formula, we use deionized water as the solvent. Compared with ordinary tap water, this avoids the darkening or residue caused by impurities in tap water, such as iron ions, thus improving product stability. It also ensures that all components of the detergent produced by this invention are evenly dissolved, resulting in better performance. Example 4

[0067] In this embodiment, we provide an application of an anti-mildew and antibacterial detergent composition, comprising an anti-mildew and antibacterial detergent composition, and applying it to laundry detergent.

[0069] The specific performance is shown in Table 1 below.

[0074] The specific performance is shown in Table 2 below.

[0075] .
