Problems solved by technology

CN105567454A discloses an antibacterial laundry liquid, which contains a composite antibacterial agent comprising nano-silver and a natural plant-derived antibacterial agent. The natural plant-derived antibacterial agent is aloe extract and lemon extract, but, due to the aloe extract and lemon extract Poor stability limits its application to a large extent
But CN106798716A, CN102860923B relate to hand sanitizer, and its formula is not suitable for washing liquid
[0007] In addition, in order to make the laundry detergent clean, soft, color-protecting, antistatic, and non-irritating to the skin, it is necessary to add a variety of additives. The formula is very complicated, the cost increases, and the content of effective substances decreases.

Embodiment 1

[0033] The preparation method of the laundry detergent is as follows: add 40 grams of fatty alcohol polyoxyethylene ether sodium sulfate, 40 grams of α-alkenyl sodium sulfonate, 80 grams of fatty acid potassium and 70 grams of fatty alcohol polyoxyethylene ether into water at 40°C. Then, with rapid stirring, 90 grams of polyacrylic acid was slowly added. After stirring evenly, add 10 grams of biological enzyme (liquid protease), 10 grams of enzyme stabilizer 4-formylphenylboronic acid, 10 grams of chelating agent, and 5 grams of essence. When the temperature is lowered to 30° C., add 1 gram of silver nanoparticles Ag-cit, make up the remaining water, and stir evenly to obtain the laundry detergent with antibacterial properties.

Embodiment 2

[0035] The preparation method of the laundry detergent is as follows: 60 grams of fatty alcohol polyoxyethylene ether sodium sulfate, 40 grams of α-alkenyl sodium sulfonate, 80 grams of fatty acid potassium and 30 grams of fatty alcohol polyoxyethylene ether are added to water at 60°C. Then, with rapid stirring, 100 grams of polyacrylic acid was slowly added. After stirring evenly, add 10 grams of biological enzyme (liquid protease), 10 grams of enzyme stabilizer 4-formylphenylboronic acid, 10 grams of chelating agent, and 5 grams of essence. When the temperature is lowered to 20° C., 5 grams of silver nanoparticles Ag-cit are added, the remaining water is supplemented, and the mixture is evenly stirred to obtain the laundry detergent with antibacterial properties.

Embodiment 3

[0037] The preparation method of the laundry detergent is as follows: add 40 grams of fatty alcohol polyoxyethylene ether sodium sulfate, 20 grams of α-alkenyl sodium sulfonate, 60 grams of fatty acid potassium and 80 grams of fatty alcohol polyoxyethylene ether into water at 50°C. Then, with rapid stirring, 50 grams of polyacrylic acid was slowly added. After stirring evenly, add 10 grams of biological enzyme (liquid protease), 10 grams of enzyme stabilizer 4-formylphenylboronic acid, 10 grams of chelating agent, and 5 grams of essence. When the temperature is lowered to 30° C., 10 grams of silver nanoparticles Ag-cit are added, the remaining water is supplemented, and the mixture is evenly stirred to obtain the laundry detergent with antibacterial properties.

Abstract

The invention relates to an antibacterial laundry detergent and application thereof. The antibacterial laundry detergent is composed of, by weight percentage, 0.1-1.0% of silver nanoparticles and 13.0-30.0% of surfactant, wherein the surfactant is a mixture of anionic surfactant and nonionic surfactant, the anionic surfactant is composed of fatty alcohol-polyoxythylene ether sodium sulfate, alpha-sodium alkenyl sulfonate and potassium aliphatate, and the nonionic surfactant is fatty alcohol-polyoythylene ether. The antibacterial laundry detergent also comprises acrylic polymers and other auxiliaries such as bio-enzymes, enzyme stabilizer, chelating agent and fragrance. The antibacterial laundry detergent has the advantages of being clean in washing, easy to rinse, antibacterial, anti-static, soft, good in color preservation and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of detergents, in particular to an antibacterial laundry detergent and its application. Background technique [0002] Laundry liquid has the characteristics of mildness, easy dissolution and low energy consumption. In the European, American and Japanese markets, laundry detergent has accounted for 40-80% of the detergent market. Laundry liquid started late in my country, and its market share is still very low, but the laundry liquid market has maintained rapid growth in recent years. As people's awareness of laundry detergent continues to deepen, people's demand for laundry detergent is also increasing. In addition to requiring good detergency, other functions are also required, such as mild and not hurting hands, easy to rinse, soft, and anti-aging. Static electricity, brightening, green and environmental protection. [0003] Improving cleanliness is a constant goal of laundry detergent manufacturers. I...
