Abstract
The invention relates to the technical field of daily chemicals, in particular to a clothes detergent composition, a preparation method and application thereof. The laundry detergent composition of the present invention comprises a foaming agent, a degreasing agent, and a biocide comprising parachlorometaxylenol and a silver ion biocide. The parachlorometaxylenol and the silver ion bactericide are compounded in a mass ratio of 10-40:5-25 to generate obvious synergistic effect, and the antibacterial effect on common opportunistic pathogens in clothes is greatly improved in a compounding mode under the condition that the concentration of single active ingredients and the concentration of total active ingredients are obviously lower than the concentration of conventional dosage. The addition amount of the bactericide in the laundry detergent composition is obviously lower than the conventional dosage, the production cost is lower, the market prospect is high, and the antibacterial requirement of a low-and-medium-price laundry detergent product on various common opportunistic pathogens can be met.
Description
Technical Field
The invention relates to the technical field of daily chemicals, in particular to a clothes detergent composition, a preparation method and application thereof.
Background
The antibacterial agent component is added into the clothes washing agent, so that on one hand, the fabric can be protected, and on the other hand, the damage of bacteria to the skin can be inhibited. With the development of economy and technology, laundry detergents with bacteriostatic action are favored by consumers.
In currently marketed underwear detergent products, the added antibacterial agent is usually triclosan, dichloroson, silver ion or the like. The triclosan or triclocarban has strong skin irritation, and may cause allergic symptoms such as erythra and pruritus, and even leukemia, and has certain carcinogenic risk. Triclosan is a bactericide developed by BASF corporation, has a chemical structure very similar to triclosan, and has a good inhibitory effect on mold, but has a high effective concentration, and generally requires more than 0.5%. And the bactericide has high price, so the comprehensive cost of using the triclosan is high. While the safety of silver ions is improved, the cost is high.
In view of this, the present invention has been made.
Disclosure of Invention
In order to solve the technical problems, the invention provides a laundry detergent composition. The antibacterial agent compounded by the parachlorometaxylenol and the silver ion antibacterial agent is added in the clothes detergent composition, has a synergistic effect, can realize a good antibacterial effect with lower cost, has mild product property, does not hurt hands, and is suitable for washing clothes (especially underwear or underpants) by hand. The laundry detergent composition provided by the invention is used for cleaning laundry, and the laundry can maintain an obvious antibacterial effect for a long time after being dried.
Specifically, the technical scheme of the invention is as follows:
in a first aspect, the present invention provides a laundry detergent composition comprising a foaming agent, a degreasing agent and a biocide, the biocide comprising parachlorometaxylenol and a silver ion biocide, the mass ratio of parachlorometaxylenol to the silver ion biocide being 10-40:5-25.
Para-chloro-m-xylenol is an organic compound with bactericidal activity that is highly corrosive and typically requires dilution to a safe concentration prior to use. The diluted parachlorometaxylenol solution has no broad-spectrum bactericidal property, has weak antibacterial effect on common opportunistic pathogenic bacteria such as candida albicans and escherichia coli in clothes, and is difficult to meet the antibacterial function requirement of a clothes detergent product on various common pathogenic bacteria. The silver ion bactericide is a long-acting bactericide, and can realize the antibacterial function by destroying proteins. The sterilizing effect of the silver ion sterilizing agent is positively correlated with the silver ion concentration. Although the silver ion bactericide with higher concentration can effectively inhibit various pathogenic bacteria, the production cost can be obviously increased; the silver ion bactericide with lower concentration has weaker antibacterial effect on common opportunistic pathogens in clothes such as staphylococcus aureus, candida albicans, escherichia coli and the like, and the defects limit the application of the silver ion bactericide in low-and-medium-price clothes detergent products.
The laundry detergent composition of the invention is added with a bactericide compounded by parachlorometaxylenol and silver ion bactericide. The parachlorometaxylenol and the silver ion bactericide are compounded in a mass ratio of 10-40:5-25, so that obvious synergistic effect can be generated. Under the condition that the concentration of single active ingredients and the concentration of total active ingredients of the parachlorometaxylenol and silver ion bactericide are obviously lower than the concentration of the conventional dosage, the antibacterial effect on common opportunistic pathogens (such as staphylococcus aureus, escherichia coli, candida albicans and the like) in clothes is greatly improved in a compound mode.
