Lasting antibacterial laundry detergent and preparation method thereof

Abstract

The invention discloses a lasting bacteriostatic laundry detergent and a preparation method thereof. The lasting bacteriostatic laundry detergent is prepared from the following raw materials in percentage by mass: 5 to 20 percent of anionic surfactant, 5 to 20 percent of nonionic surfactant, 0.5 to 10 percent of fatty acid, 0.1 to 5 percent of bacteriostatic agent, 0.1 to 5 percent of citric acid monohydrate, 1 to 10 percent of alkali, 0.1 to 5 percent of modified acrylic polymer, 0.05 to 0.5 percent of protease, 0.05 to 0.5 percent of preservative, 0.05 to 0.5 percent of essence, 0.05 to 0.5 percent of sodium chloride and the balance of deionized water. The laundry detergent has an efficient and rapid antibacterial effect and can be used for rapidly removing escherichia coli and staphylococcus aureus; the laundry detergent has a good lasting bacteriostatic effect, can achieve 72-hour lasting bacteriostasis on escherichia coli, staphylococcus aureus and klebsiella pneumoniae, and can effectively inhibit bacterial reproduction, prevent peculiar smell and maintain long-acting freshness of fabrics for clothes aired indoors or dried in the shade in a humid environment.

Description

technical field [0001] The invention relates to the technical field of household cleaners, in particular to a long-lasting antibacterial laundry detergent and a preparation method thereof. Background technique [0002] With the continuous impact of the new crown epidemic, the daily chemical products of disinfection and sterilization have shown explosive growth. For laundry detergent, the antibacterial effect is an important subdivision and development direction of laundry detergent. But there are many shortcomings in the laundry detergent of current bacteriostatic effect, can not fully meet the needs of consumers, such as: the bacteriostatic technology represented by silver ion can quickly bacteriostatic effect, but the lasting bacteriostatic effect is poor; The antibacterial technology represented by triclosan and triclosan has good long-lasting antibacterial effect, but in the laundry process, its antibacterial effect is easily shielded by the surfactant in the laundry liq...

Problems solved by technology

But there are many shortcomings in the laundry detergent of current bacteriostatic effect, can not fully meet the needs of consumers, such as: the bacteriostatic technology represented by silver ion can quickly bacteriostatic effect, but the lasting bacteriostatic effect is poor; The antibacterial technology represented by triclosan and triclosan has good long-lasting antibacterial effect, but in the laundry process, its antibacterial effect is easily shielded by the surfactant in the laundry liquid, so the rapid antibacterial effect is poor. In addition, three Chlorosan and triclocarban have potential health risks, which have greatly affected the application in laundry detergent; bacteriostatic agents represented by p-chlororesorcinol have heavy raw material odor, poor stability, and poor antibacterial efficacy; Cationic bacteriostatic agents represented by quaternary ammonium salts and guanidines have poor compatibility with anionic surfactants in laundry detergent, which affects the performance of laundry detergent; bleaching agents represented by sodium hypochlorite and hydrogen peroxide, due to the poor stability of raw materials, It is highly corrosive, has poor compatibility with laundry detergent, and has a strong smell of sodium hypochlorite, making it difficult to apply in laundry detergent

[0003] Therefore, the preparation of antibacterial laundry detergent in the prior art has the following disadvantages more or less: poor rapid antibacterial effect, weak persistent antibacterial effect, heavy smell, poor stability, high safety risk, etc., and affects the cleaning and thickening of laundry detergent Etc performance
