The laundry detergent has the advantages of mild sterilization, no residue and easy degradation, is suitable for washing infant clothes and close-fitting clothes, and has wide application prospect. Meanwhile, the invention also provides a preparation method of the mild sterilization laundry detergent.
Description
Technical Field
The invention belongs to the field of washing products, and particularly relates to a mild bactericidal laundry detergent and a preparation method thereof.
Background
Compared with washing powder, the laundry detergent has the advantages of easy dissolution, high active matter content, convenient use and the like, and is very popular with people. However, most of the conventional laundry detergent formulations use sulfate, alcohol ether carboxylate or sulfonate surfactants as active substances, alkanolamide 6501 as a thickening agent, alcohol ether and alcohol ether glycoside substances as main components, dioxane easily remains, and C is8-16The quaternary ammonium salt cationic surfactant is used as a bactericide, so that the laundry detergent has strong irritation, harmful substances are easy to remain on washed articles, the laundry detergent is used for washing clothes, especially infant clothes and underwear, the body health of people can be affected, and meanwhile, the formula contains a part of difficultly-degradable components and can pollute the environment. Therefore, the development of a laundry detergent which has biocompatibility, has a killing effect on pathogenic microorganisms, has no harmful substance residue, and is mild and moist to skin can meet new requirements of people on clothes health and environmental protection.
The glucoside citrate surfactant has good stability, can chelate metal ions to improve the hard water resistance of a formula, has excellent low-temperature solubility and easy rinsing performance, can be compounded with various surfactants and assistants, cannot form an insoluble organic complex particularly when being compounded with a cationic surfactant or other cationic assistants, and is a green multifunctional surfactant. Although alkyl glycoside citrate belongs to alkyl glycoside citrate surfactants, the main production raw materials of fatty alcohol, glucose, citric acid and the like are biomass-based renewable raw materials derived from natural products, are safe, non-toxic and easy to degrade, the product is not localized at present due to the limitation of the production technology of the alkyl glycoside citrate, and the application cost is greatly improved mainly by depending on the over-high price of the imported product. Therefore, the method for synthesizing the alkyl glycoside citrate which is low in cost and easy to dissolve in the laundry detergent is developed, and has important practical significance for developing the bactericidal laundry detergent with mild research performance.
Disclosure of Invention
In view of the above, the invention provides a mild bactericidal laundry detergent and a preparation method thereof, so as to solve the above problems.
Specifically, the invention adopts the following technical scheme:
the mild sterilization laundry detergent comprises the following components in parts by mass based on 100 parts by mass: 1.0-3.0 parts of alkyl glycoside citrate, 3.0-10.0 parts of alkyl glycoside, 1.5-2.5 parts of glycosyl amide quaternary ammonium salt, 1.5-3.0 parts of artemisinin extracting solution, 0.1-1 part of thickening agent, 0.1-5 parts of other auxiliary agents and the balance of deionized water.
Preferably, the alkyl glycoside citrate is a compound having the general formula:
wherein R is an alkyl group having a carbon chain length of 8 to 14 carbons, and n is 1.2 to 1.6.
Preferably, the quaternary ammonium glycosylamide salt is a compound having the general formula:
wherein R is1Is glucosyl or lactose group; r2Is an alkyl group having a carbon chain length of 10 to 16 carbons.
Based on the above, it comprises the following components in parts by mass, calculated as 100 parts by mass: 1.8-2.5 parts of alkyl glycoside citrate, 7.0-7.5 parts of alkyl glycoside, 1.5-2.5 parts of glycosyl amide quaternary ammonium salt, 2.0-2.5 parts of artemisinin extracting solution, 0.5-4 parts of thickening agent, 0.5-0.7 part of other auxiliary agents and the balance of deionized water.
Based on the above, the artemisinin extracting solution is obtained by steaming, extracting and concentrating dry artemisia apiacea leaves by deionized water, and the concentration of artemisinin in the artemisinin extracting solution is 1.5-2.5 g/ml.
Based on the above, the thickener is sodium alginate, xanthan gum or pectin.
Based on the above, the other auxiliary agents are one or a mixture of at least two of essence, fluorescent whitening agent, sodium hydroxide, potassium hydroxide and pigment.
Based on the above, the pH value of the mild sterilization laundry detergent is 7.0-7.5.
The preparation method of the mild bactericidal laundry detergent comprises the following steps: firstly, reacting citric acid and alkyl glucoside in a reaction kettle with a stirring head and an emulsifying head in the kettle under the vacuum condition under the catalysis of a hydrogen peroxide composite catalyst to obtain a mixed solution of alkyl glucoside citrate and alkyl glucoside; adding glycosyl amide quaternary ammonium salt, artemisinin extracting solution, thickening agent, other auxiliary agents and deionized water into the mixed solution, and uniformly mixing to obtain a laundry detergent product; the hydrogen peroxide composite catalyst comprises ethylene diamine tetraacetic acid and hydrogen peroxide, and the mass ratio of the ethylene diamine tetraacetic acid to the hydrogen peroxide is (96-99): (1-4).
