Description

Technical Field

[0001] This invention relates to the field of daily chemical products technology, specifically to an antibacterial laundry detergent containing Cnidium monnieri, matrine, and Marseille soap, and its preparation method. Background Technology

[0002] In recent years, with the continuous improvement of consumers' demand for healthier and more functional laundry products, the introduction of natural plant extracts into laundry detergent formulas has become an important development trend in the industry. Cnidium monnieri extract and matrine are both naturally derived antibacterial active ingredients. The former is rich in osthol and focuses on inhibiting fungi, while the latter is a quinolone alkaloid that focuses on inhibiting bacteria. Marseille soap is a sodium salt of fatty acids obtained from olive oil through saponification, which has both excellent detergency and natural mildness. The scientific combination of the above three components is expected to achieve a synergistic unity of "detergent removal + antibacterial" dual effects in the laundry detergent field.

[0003] Existing antibacterial laundry detergents are typically prepared by mixing and stirring components such as soap base, surfactants, additives, and water. Soap base is the main detergency agent, surfactants assist in detergency and solubilization, and additives are used to adjust system stability and improve performance. The conventional preparation process involves heating the soap base and water to above 80°C to completely melt them, then sequentially adding surfactants, additives, and other functional components, stirring continuously until homogeneous, and finally cooling and discharging.

[0004] However, the aforementioned existing technologies reveal the following problems in practical applications: In humid environments, soap base itself lacks antibacterial capabilities, easily breeding microorganisms and causing odors in clothing, thus requiring the addition of additional antibacterial ingredients; although chemically synthesized bactericides (such as quaternary ammonium salts) have significant antibacterial effects, their cationic properties react with the anionic surfactants of soap base, causing precipitation and resulting in stratification and turbidity in the formulation; although plant essential oils are naturally derived, their oil-soluble nature makes them difficult to disperse stably in aqueous systems, leading to precipitation and stratification after long-term storage; furthermore, osthol and matrine are both heat-sensitive substances, and the traditional process of adding all components at once after melting the soap base at high temperatures causes the extracts to undergo oxidative decomposition in environments above 80°C, significantly reducing their antibacterial activity. To address these shortcomings, this paper proposes an antibacterial laundry detergent containing osthol, matrine, and Marseille soap, and its preparation method. Summary of the Invention

[0005] In view of this, the present invention provides an antibacterial laundry detergent containing Cnidium monnieri, matrine and Marseille soap and its preparation method, in order to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0006] The technical solution of this invention is achieved as follows: an antibacterial laundry detergent, comprising the following components by weight:

[0007] Cnidium monnieri extract 0.5-10 parts

[0008] Matrine 0.2-8 parts

[0009] Marseille soap, 5-30 pieces

[0010] 5-25 parts of surfactant

[0011] 0.5-10 parts of auxiliary agent

[0012] 30-80 parts water.

[0013] More preferably, by weight, it comprises the following components:

[0014] 1-6 parts of Cnidium monnieri extract

[0015] Matrine 0.5-5 parts

[0016] Marseille soap (10-25 pieces)

[0017] 8-20 parts of surfactant

[0018] 1-8 parts of auxiliary agent

[0019] 40-70 parts water;

[0020] The Marseille soap is a sodium salt of fatty acids obtained from olive oil through a saponification reaction, and its fatty acid content is 72% by mass.

[0021] More preferably, the Cnidium monnieri extract is an alcoholic or aqueous extract of Cnidium monnieri, wherein the mass content of osthol is 0.5%-10%; the surfactant is selected from one or more of the following: alkyl glycosides, sodium lauryl alcohol polyoxyethylene ether sulfate, lauryl propylamine oxide, and coconut oil fatty acid diethanolamide.

[0022] More preferably, the adjuvant includes a chelating agent, a pH adjuster, and an enzyme preparation; the chelating agent is disodium ethylenediaminetetraacetate, the pH adjuster is citric acid, and the enzyme preparation is a protease.

[0023] More preferably, the weight ratio of the Cnidium monnieri extract to the matrine is 1:0.2-1:5.

[0024] More preferably, the antibacterial laundry detergent has a pH value of 6.0-8.0.

[0025] This invention provides a method for preparing the aforementioned antibacterial laundry detergent, comprising the following steps:

[0026] S1. Add Marseille soap to some water, heat to 40-80℃ and stir to dissolve, to obtain Marseille soap solution;

[0027] S2. Add the Cnidium monnieri extract, matrine, surfactant, and auxiliaries to the remaining water, and stir and mix evenly at 20-60℃ to obtain a mixture.

[0028] S3. Combine the Marseille soap solution obtained in step S1 with the mixture obtained in step S2, stir evenly, and adjust the pH value to 6.0-8.0 to obtain the antibacterial laundry detergent.

[0029] More preferably, the heating temperature in step S1 is 50-70℃; the stirring and mixing temperature in step S2 is 25-50℃, and the stirring time is 10-60 minutes.

[0030] In a further preferred embodiment, citric acid is used to adjust the pH value in step S3.

[0031] The present invention provides the application of the antibacterial laundry detergent described above in the preparation of laundry detergent, wherein the antibacterial laundry detergent has an inhibitory effect on Staphylococcus aureus, Escherichia coli and Candida albicans.

[0032] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0033] I. This invention constructs a plant-derived binary synergistic antibacterial system by compounding Cnidium monnieri extract and matrine in a specific ratio (1:0.2-1:5). Osthol focuses on inhibiting fungi, while matrine focuses on inhibiting bacteria. The two have complementary antibacterial mechanisms, resulting in a significant synergistic effect. The inhibition rate against Staphylococcus aureus, Escherichia coli, and Candida albicans all reach over 99%, achieving a broad-spectrum and highly effective antibacterial effect. A specific Marseille soap (olive oil source, 72% fatty acid content) is selected as the soap base source. Its fatty acid composition is pure and has excellent compatibility with plant active ingredients, effectively avoiding stability problems such as stratification and precipitation. At the same time, the "soap base + mild synthetic surfactant" compound system is adopted, which takes into account both detergency and gentleness, avoiding the compatibility defects of chemical bactericides and soap base. The use of water-soluble Cnidium monnieri extract to replace traditional plant essential oils fundamentally solves the technical problem of easy stratification and turbidity of plant-derived components in water.

[0034] II. In terms of the preparation process, this invention employs a "stepwise dissolution and low-temperature mixing" technique. After the Marseille soap is dissolved by heating alone, heat-sensitive plant extracts are introduced at a low temperature. This effectively avoids the damage to osthol and matrine caused by high temperatures, maximizing the preservation of the antibacterial efficacy of the active ingredients. Furthermore, controlling the pH value between 6.0 and 8.0 ensures the dual stability of the soap base and the plant active ingredients.
