Description

Kitchen detergent and preparation method thereof

Technical Field

The application relates to the technical field of cleaning agents, in particular to a kitchen detergent and a preparation method thereof.

Background

The tea saponin has certain antibacterial property and is a surfactant. The tea saponin molecule mainly comprises hydrophobic aglycone, hydrophilic organic acid and saccharide (the hydrophilic organic acid and saccharide contain a large amount of hydrophilic carboxyl and hydroxyl); because of the unique hydrophilic-hydrophobic structure, pure tea saponin can be used as a surfactant, but the surface activity of the tea saponin can exert excellent surface activity effect after further modification.

Modification of tea saponin molecules is generally undertaken from two aspects: 1. modifying hydroxyl or carboxyl, and modifying nonionic tea saponin into an anionic, cationic or zwitterionic surfactant, so as to improve the surface activity of the tea saponin; 2. degrading glycosyl of tea saponin to obtain active aglycone with physiological activity of resisting tumor, virus and diabetes.

The current method for modifying tea saponin comprises obtaining tea saponin modified by organosilicon quaternary ammonium salt through organosilicon modification of tea saponin; polymerizing epoxypropane and tea saponin under the action of a catalyst to obtain a tea saponin polyether derivative; the tea saponin high-grade fatty acid ester is obtained by modifying the tea saponin with high-grade fatty alcohol; modifying the tea saponin by a sulfating reagent to obtain tea saponin sulfate; modifying tea saponin with succinic anhydride to obtain tea saponin succinate.

However, after the tea saponin is modified, although the surface activity of the modified tea saponin is greatly improved, the antibacterial performance of the modified tea saponin is reduced. When the detergent is used for cleaning kitchens, due to the fact that oil stains, bacteria, mold and the like are contained in kitchens, and in order to achieve excellent sterilization and decontamination effects, the detergent for kitchens, which is based on tea saponin and has excellent antibacterial and cleaning capabilities, is very necessary to be obtained.

Performance detection

(I) sterilizing Properties

According to disinfection technical specification-2019, a suspension quantitative sterilization experiment is adopted, a sample to be detected is diluted by 100 times with sterile water, and then the sterilization effect is measured, wherein the sterilization time is 1 h.

The kitchen detergents prepared in examples 1 to 13 and comparative examples 1 to8 were tested for their bactericidal effects, and the bactericidal effects on staphylococcus aureus ATCC 6538, pseudomonas aeruginosa ATCC 15442, escherichia coli 8099, candida albicans ATCC 10231 and aspergillus niger ATCC16404 were measured, respectively, and the viable bacteria concentration (cfg/mL) of each group after sterilization was calculated, and the sterilization rate (%) was calculated, and the specific results are shown in table 1.

Sterilization rate (%) = (initial viable cell count (cfu/mL) -viable cell count after sterilization (cfu/mL))/initial viable cell count (cfu/mL) × 100%.

TABLE 1

As seen from the data results of examples 1-13 in Table 1, the kitchen detergent prepared by the method has excellent antibacterial capacity, and the sterilization rates of the kitchen detergent on staphylococcus aureus, pseudomonas aeruginosa, escherichia coli, candida albicans and aspergillus niger are 96.3-99.6%, 95.2-99.7%, 94.6-99.2%, 84.4-98.8% and 86.7-98.7%, respectively.

As can be seen from the data results of examples 3-6, the kitchen detergent prepared using two organic acids has a higher bactericidal activity when the organic acids are selected than when one organic acid is used alone. Especially for fungi (candida albicans and aspergillus niger), the sterilizing rate is obviously improved; the sterilization rate of the kitchen detergent in the embodiment 6 on candida albicans is improved by 7.65-12.46% compared with that of the kitchen detergent in the embodiments 3-5; compared with the kitchen detergent of embodiments 3-5, the kitchen detergent of embodiment 6 has an Aspergillus niger sterilization rate improved by 5.13-10.55%.

As seen from the data results of examples 6 to 7, when acrylic acid and glycolic acid are used as the organic acid, the amount of acrylic acid and glycolic acid can be properly controlled within the range of 1:0.1 to 0.8 by weight ratio, and if the amount exceeds the weight ratio range, the sterilizing ability of the kitchen detergent is reduced.

In addition, the results of example 6 and example 8 show that, when ellagic acid is added to the raw material for preparation in the preparation of the kitchen detergent, the sterilization rate of the kitchen detergent is further improved, so that the kitchen detergent has a stronger sterilization capability.

In example 9, three kinds of auxiliaries, tetrasodium glutamate diacetate, citric acid and glycerol, were added to the raw materials for preparing the detergent, and the addition of these three kinds of auxiliaries had no significant effect on the antibacterial effect of the kitchen detergent.

Further, the influence of the total amount of the organic acid on the kitchen detergent was further investigated by examples 10 to 11 and comparative example 6, and as a result, it was found that: the total amount of the organic acid is recommended to be controlled within the range of 5-45 g (namely 0.5-4.5 parts by weight), otherwise the sterilization rate of the prepared kitchen detergent on staphylococcus aureus, pseudomonas aeruginosa, escherichia coli, candida albicans and aspergillus niger is obviously reduced. In addition, the data result of comparative example 1 also shows that when the kitchen detergent is prepared, the organic acid must be added, otherwise the sterilization performance of the prepared kitchen detergent is significantly reduced.

While examples 12-13 and comparative examples 7-8 further explore the effect of total nuciferine usage on kitchen detergents and found that: the total dosage of the nuciferine is recommended to be controlled within the range of 50-100 g (namely 5-10 parts by weight), otherwise the sterilization rate of the prepared kitchen detergent is obviously reduced.

In addition, in comparative example 2, when the modified tea saponin was replaced with the ordinary tea saponin in the preparation of the kitchen detergent, the sterilization effect of the product was significantly reduced, so that it was difficult to obtain a product having excellent sterilization ability when the unmodified tea saponin was selected for the preparation system. The arrangements of comparative examples 3 to 4 further demonstrate that the kitchen detergent of the present application exhibits excellent bactericidal effect when modified tea saponin and nuciferine are added together, which is indispensable to the preparation of the kitchen detergent.

The detergent of comparative example 5 does not contain nuciferine, organic acid and ellagic acid which are specially added in the detergent preparation of the application, so that the sterilization effect is remarkably reduced, and the sterilization rate of each experimental bacterium is not higher than 50%.

In conclusion, when the kitchen detergent is prepared, the kitchen detergent has excellent sterilizing capability by adding nuciferine, organic acid and ellagic acid on the basis of selecting general raw materials for preparing the detergent.

(II) cleaning Properties

The detection is carried out according to GB/T35833-2018 kitchen oil stain cleanser, and the concentration of the sample is 3%.

The kitchen detergents prepared in example 3, example 6, examples 8 to 9 and comparative example 5 were measured for their cleaning ability, and the results are shown in Table 2.
