Description

Technical Field

[0001] The invention belongs to the technical field of washing products, and relates to a detergent containing natural plant extracts and a preparation method thereof. Background Art

[0002] As a necessity in daily life, dishwashing liquid is widely used to clean kitchen utensils and other supplies. Modern dishwashing liquid usually contains surfactants to remove oil and moisturizers to protect hands. It has the ability to quickly decompose grease and remove dirt, but most products are insufficient in terms of bactericidal and antibacterial properties. With the improvement of health awareness, consumers not only pursue the decontamination effect of dishwashing liquid, but also begin to pay attention to its safety and environmental protection characteristics. People have higher and higher expectations for dishwashing liquid, not only requiring it to have efficient decontamination ability, but also hoping that it is safe, has good bactericidal effect and is non-irritating. However, although the common dishwashing liquids on the market have strong decontamination ability, they are insufficient in terms of bactericidal effect. Some products are too alkaline and may cause irritation to the skin when used. Long-term use may cause dryness, peeling and roughness of the skin, which cannot meet the all-round needs of modern people for detergents.

[0003] With the rapid development of surface chemistry, some dishwashing liquids with disinfection and sterilization functions have appeared on the market. These products mainly improve their sterilization and disinfection effects by adding chemical bactericides and disinfectants. However, long-term use of such dishwashing liquids may cause damage to the skin, and may also pose a threat to human health if they are not completely removed or degraded during the rinsing process. In addition, these detergents may also pollute the environment. Therefore, choosing safe and environmentally friendly dishwashing liquids is essential to protect personal health and the environment. Summary of the invention

[0004] The present invention aims at solving the technical problems of safety and environmental protection in the existing dishwashing liquid, and provides a dishwashing liquid containing natural plant extracts. By adding oregano extract and other plant extracts, the dishwashing liquid is safe and harmless, has good decontamination ability, and performs well in sterilization effect.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The invention provides a detergent containing natural plant extracts.

[0056] Product performance test:

[0057] (1) Product testing and evaluation

[0058] 1) Physical and chemical indicators. Test and evaluate the physical and chemical properties, usage effects, and sensory effects of the product, referring to GB / T24691-2009 standard; pH value is tested with a pH meter.

[0059] 2) Appearance indicators: Observe whether the product is stratified, and whether there is any suspended matter or precipitation.

[0060] 3) Stability. Place in a refrigerator at -5±2℃ for 24 hours, take out and return to room temperature to observe whether the product has precipitation, discoloration and turbidity; place in an incubator at 40±1℃ for 24 hours, take out and return to room temperature, and observe whether the product has odor, stratification, discoloration and turbidity. The results are shown in Table 1.

[0061] Table 1 Product testing and evaluation results

[0062]

[0063]

[0064] The results show that the detergent products prepared in Examples 1 to 7 of the present invention have stable quality and excellent appearance quality.

[0065] (2) Determination of detergency

[0066] According to the requirements of the foam position method in Appendix A.2 of GB / T 9985-2022, the detergency of the detergents in Examples 1 to 3 and Comparative Examples 1 to 2 was tested. A certain amount of artificial synthetic dirt was evenly applied on the plate, and after drying, the plate was placed in a surfactant solution with a certain concentration for washing. The washing process continued until the foam layer on the surface of the solution was reduced to half, and finally, the detergency of the detergent was evaluated according to the number of plates washed. The results are shown in Table 2.

[0067] Table 2 Determination results of detergent detergency with different ratios

[0068] Example Washing plate number Example 1 4 Example 2 4.5 Example 3 5 Comparative Example 1 3 Comparative Example 2 3 Standard dishwashing detergent 2.5

[0069] The results show that the present invention uses two anionic surfactants, fatty alcohol polyoxyethylene ether sodium sulfate and secondary alkyl sulfonate, and diethanolamide and isomeric alcohol ether ( NE 9) The decontamination effect of the compound of two nonionic surfactants is better than that of the compound of a single anionic surfactant and a nonionic surfactant. The decontamination effect of the detergent of the present invention is significantly stronger than that of the standard dishwashing detergent.

[0070] (3) Determination of antibacterial rate

[0071] The plate count method was used to compare the antibacterial rates of the detergents of Examples 1 to 7 and Comparative Example 3 against Escherichia coli, Staphylococcus aureus and miscellaneous bacteria in the air. Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 6538 were purchased from the China Institute for the Authentication of Pharmaceutical and Biological Products.

[0072] Inhibition rate of Escherichia coli and Staphylococcus aureus: Use a pipette to take 0.2 mL of Examples 1 to 7, Comparative Example 3, and 0.1 mL of the test bacterial suspension, respectively, and evenly cover the surface of the LB solid culture medium with the liquid. After 30 minutes of coating, invert the plate and culture it in a 37°C incubator for 24 hours, and count the number of colonies. Each treatment was repeated 3 times, and a control group was set up. The control group used an equal amount of sterile saline instead of detergent. The concentration of Escherichia coli and Staphylococcus aureus was 1×10 5 CFU / mL.

[0073] Inhibition rate of miscellaneous bacteria in the air: Use a pipette to take 0.2 mL of Examples 1 to 5 and Comparative Example 3 respectively, so that the liquid is evenly covered on the surface of the bacterial culture medium, exposed to the air for 15 minutes, collect bacteria, culture in a 37°C incubator for 24 hours, count the number of colonies, and repeat 3 times for each treatment. A control group is also set up, and the control group uses an equal amount of sterile saline instead of detergent.

[0074] Bacterial inhibition rate = (the number of test bacteria colonies in the control group - the number of test bacteria colonies in the experimental group) / the number of test bacteria colonies in the control group × 100%. The colony counts of the control group are as follows: 121 Escherichia coli, 135 Staphylococcus aureus, and 118 miscellaneous bacteria in the air.

[0075] Table 3 Determination results of antibacterial rate of detergents in different embodiments

[0076] Escherichia coli, % Staphylococcus aureus, % Bacteria in the air, % Example 1 38.8 41.5 49.6 Example 2 52.3 54.8 65.6 Example 3 51.9 56.1 64.8 Example 4 56.7 59.3 68.5 Example 5 61.8 60.6 70.1 Example 6 64.1 61.5 69.8 Example 7 63.5 62.4 68.4 Comparative Example 3 12.3 14.5 16.6

[0077] The results show that the antibacterial effect of the dishwashing liquid with oregano extract added is significantly better than that of the dishwashing liquid without oregano extract added. The antibacterial effect of Examples 2 and 3 is stronger than that of Example 1, indicating that the antibacterial rate increases with the increase in the amount of oregano extract added. The antibacterial rates of Examples 2 to 7 all reach more than 50%, showing obvious antibacterial effects, especially the dishwashing liquids with clove leaf extract, purslane extract, Kochia scoparia extract, and honeysuckle vine extract added, the antibacterial effect is further improved.

[0078] The embodiments described above are only preferred embodiments of the present invention and are only used to explain the present invention, not to limit the scope of implementation of the present invention. For those skilled in the art, other implementation methods can certainly be easily made by replacement or modification based on the technical contents disclosed in this specification.
