Description

Technical Field

[0001] The present invention relates to the field of A61K8 / 18, and in particular to an antibacterial clothing cleaning composition containing colloidal silver and a preparation method thereof. Background Art

[0002] As people pay more attention to daily hygiene, demand for antibacterial hand soaps, disinfectants, and laundry detergents is increasing. Currently, the antibacterial ingredients used in detergents on the market mostly include triclosan, triclocarban, parachlorometaxylenol, and sodium hypochlorite. Literature suggests that triclosan and triclocarban may be reproductively toxic and pose certain risks. Parachlorometaxylenol and surfactants can easily cause the antibacterial properties of these products to be lost. Sodium hypochlorite is a strong oxidizing agent, highly alkaline, and highly corrosive. Silver ions, as a new type of antibacterial agent, particularly colloidal silver, offer broad-spectrum antibacterial effects, anti-inflammatory properties, immune-boosting properties, and a high safety profile, making them increasingly popular in detergents. For example, a Chinese patent (authorization publication number CN 110106039B) discloses an antibacterial laundry detergent containing colloidal silver for infants and young children. This solution primarily addresses the needs of infants and young children by adding colloidal silver to the laundry detergent system. However, colloidal silver antimicrobial agents have poor stability and are easily affected by light and heat. They also age and degrade after prolonged storage, causing the product's appearance to change to gray and reducing its antibacterial effect. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides an antibacterial clothing cleaning composition containing colloidal silver. By optimizing the product formula system, the problem of poor stability of colloidal silver antibacterial agents is overcome. The color of the product does not change significantly when affected by light or heat or after being stored for a long time, and the antibacterial rate of the product remains within the standard range.

[0004] On one hand, the present invention provides an antibacterial clothing cleaning composition containing colloidal silver. The raw materials for preparing the composition include, by mass percentage, 11-25% of a sulfate ester salt, 2-6% of an alkylbenzenesulfonic acid anionic surfactant, 2-6% of a zwitterionic surfactant, 0.5-1.0% of colloidal silver, 0.5-5.0% of a thickener, 0.02-0.5% of magnolol, 0-0.5% of a chelating agent, 0-1.0% of a preservative, 0-2.0% of a fragrance, 0.3-0.8% of an alkaline regulator, 0.01-0.2% of an acidic regulator, 0-2.0% of sodium chloride, and the balance made up of deionized water.

[0005] As a preferred technical solution, the sulfate ester salt is sodium lauryl sulfate and / or sodium lauryl polyether sulfate, preferably sodium lauryl polyether sulfate.

[0006] As a preferred technical solution, the alkylbenzenesulfonic acid anionic surfactant includes at least one of dodecylbenzenesulfonic acid and sodium dodecylbenzenesulfonate, preferably dodecylbenzenesulfonic acid.

[0007] As a preferred technical solution, the zwitterionic surfactant is an amine oxide surfactant, preferably cocamidopropylamine oxide.

[0008] As a preferred technical solution, the mass ratio of the alkylbenzene sulfonic acid anionic surfactant, sulfate ester salt, and zwitterionic surfactant is (2-6): (11-18): (2-6), preferably (3-5): (12-16): (3-5).

[0009] The cleaning composition provided by the present invention simultaneously incorporates dodecylbenzenesulfonic acid, sodium laureth sulfate, and cocamidopropylamine oxide, thereby ensuring the product's cleaning effectiveness while reducing its irritation. In particular, when the mass ratio of the alkylbenzenesulfonic acid anionic surfactant, sulfate ester salt, and zwitterionic surfactant is controlled to (2-6):(11-18):(2-6), the thickener and magnolol in the system ensure the stability of the cleaning composition containing colloidal silver. However, when nonionic surfactants of fatty alcohol polyethers (such as AEO-3, AEO-7, and AEO-9) are added, the sample becomes less stable, easily thins at low temperatures, and has an antibacterial effect of less than 50%.

[0010] As a preferred technical solution, the thickener is selected from at least one of maleic acid-acrylic acid copolymer and acrylic acid (ester) / C10-30 alkyl acrylate cross-linked polymer, preferably maleic acid-acrylic acid copolymer.

[0011] As a preferred technical solution, the mass ratio of the magnolol to the maleic acid-acrylic acid copolymer is (0.02-0.5):(0.5-5), preferably (0.02-0.5):(2-5), and more preferably 0.05:(3-5).

[0012] Furthermore, the present invention fully ensures the stability of the cleaning composition containing colloidal silver by simultaneously introducing magnolol and maleic acid-acrylic acid copolymer, ensuring that the provided composition will not change color or reduce the antibacterial effect under the influence of external factors such as temperature changes.

[0013] As a preferred technical solution, the chelating agent is disodium EDTA.

[0014] As a preferred technical solution, the acidic regulator is citric acid; the alkaline regulator is sodium hydroxide.

[0015] As a preferred technical solution, the preservative is selected from at least one of chlorphenesin, phenoxyethanol, caprylyl glycol, p-hydroxyacetophenone, and chlorphenesin, preferably chlorphenesin.

[0016] Another aspect of the present invention provides a method for preparing an antibacterial clothing cleaning composition containing colloidal silver, comprising at least the following steps:

[0017] (1) adding a chelating agent, a thickener, and an alkylbenzene sulfonic acid anionic surfactant into deionized water, and adding an alkaline regulator and stirring and mixing;

[0018] (2) adding sulfate ester salt and zwitterionic surfactant and stirring and mixing;

[0019] (3) Add colloidal silver, magnolol, flavor, and preservative and stir to mix;

[0020] (4) Add an acidity regulator and sodium chloride and stir to obtain an antibacterial clothing cleaning composition containing colloidal silver.

[0021] The present invention further ensures the stability of the cleaning composition by optimizing the preparation process and controlling the addition sequence of the raw materials.
