Technical Field

[0001] The invention belongs to the technical field of daily necessities, and in particular relates to a washing disinfectant with a long-lasting bactericidal effect and a preparation method thereof. Background Art

[0002] As an indispensable product in daily life and industrial production, the performance and quality of detergents and disinfectants have also received more and more attention. Traditional detergents and disinfectants are mainly chemically synthesized. Although they have strong cleaning and sterilization capabilities, they often have problems such as severe skin irritation and serious environmental pollution.

[0003] With the advancement of science and technology and the enhancement of environmental awareness, new chemical ingredients are gradually introduced into detergents and disinfectants to improve the cleaning and sterilization effects of the products while reducing skin irritation and environmental pollution.

[0004] However, there are still some problems with the detergent disinfectants in the prior art, such as the bactericidal effect is not long-lasting enough. In order to solve the above problems, a detergent disinfectant with a long-lasting bactericidal effect is proposed. Summary of the invention

[0005] The object of the present invention is to provide a detergent disinfectant with a long-lasting bactericidal effect and a preparation method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0009] The pH of the detergent disinfectant is greater than 12.

[0010] A method for preparing a detergent disinfectant with a long-lasting bactericidal effect comprises the following steps:

[0011] S1, filtering the aloe vera extract and the soybean fermentation extract through a microfiltration membrane;

[0012] Cut fresh soap nuts into small pieces and soak them in water for 24 hours, boil them to extract the active ingredients, and filter them;

[0013] S2. Heat deionized water to 50°C-55°C, add water-soluble permanganate, oxidant, pH adjuster and boron-containing stabilizer, and stir slowly until completely dissolved;

[0014] S3. While maintaining gentle stirring, slowly add the nano-platinum disinfection component and use ultrasonic dispersion technology to evenly disperse the nanoparticles in the solution;

[0015] S4, slowly adding the pretreated coconut oil, aloe vera extract, soybean fermentation extract and saponin extract into the mixed solution, stirring while adding, and adjusting the pH value;

[0016] S5. The mixed solution is matured at a constant temperature of 60°C-65°C for 2 hours, with regular stirring during the period. After maturation, the mixed solution is cooled to room temperature to obtain a detergent disinfectant.

[0017] Preferably, in S1, the Aloe vera extract is filtered through a 0.22 micron microfiltration membrane, and the filtration rate is controlled at 500 mL / min;

[0018] The soybean fermentation extract was filtered through a 0.22-μm microfiltration membrane, and the filtration rate was maintained at 400 mL / min;

[0043] Embodiment 2:

[0044] The difference from the first embodiment is that a detergent disinfectant with a long-lasting bactericidal effect comprises the following components in parts by weight:

[0045] 2.5% soluble permanganate, 1.2% oxidant, 20% pH adjuster, 1.5% boron stabilizer, 0.0028% nano-platinum disinfection component, 8% coconut oil, 7% aloe vera extract, 6% soybean fermentation extract, 1.8% fresh saponin, and the balance is deionized water;

[0046] The rest of the parts are the same as those in the first embodiment and will not be described in detail here.

[0047] Application test examples:

[0048] The test materials are:

[0049] Sample A: a detergent disinfectant prepared in the prior art;

[0050] Sample B: a detergent disinfectant prepared according to Example 2;

[0051] Sample C: a detergent disinfectant prepared according to Example 1.

[0052] Test stains:

[0053] Artificially simulated daily stains (such as grease, protein, carbohydrates, etc.);

[0054] Microbial contamination (such as Escherichia coli, Staphylococcus aureus, etc.).

[0055] Cleaning ability test:

[0056] Samples A, B, and C were applied to fabrics containing simulated daily stains, and washed according to the standard washing procedure. The residual stains on the fabrics after washing were evaluated, as shown in the following table:

[0057]

[0058] The stain residue of sample A after cleaning is 0.05g, and the cleaning efficiency is 90%; the stain residue of sample B after cleaning is 0.03g, and the cleaning efficiency is 94%; the stain residue of sample C after cleaning is 0.02g, and the cleaning efficiency is the highest, reaching 96%, which indicates that sample C performs best in terms of cleaning ability.

[0059] Skin mildness test:

[0060] Samples A, B, and C were applied to the artificial skin model, and the changes in the skin model (such as redness, swelling, irritation, etc.) were observed and recorded to evaluate the skin mildness of the detergent and disinfectant, as shown in the following table:

[0061]

[0062] The skin irritation index of sample A is 3, which is slightly irritating; the skin irritation index of sample B is 2, which is relatively mild; the skin irritation index of sample C is 1, which is very mild, which indicates that sample C performs best in terms of skin mildness.

[0063] Stability test:

[0064] Samples A, B, and C were placed in high temperature, low temperature, and light stability test chambers, respectively, and tested according to the standard stability test procedure to evaluate the stability of the detergent disinfectant (such as color change, odor change, component degradation, etc.), as shown in the following table:

[0065]

[0066] All samples (A, B, C) showed good stability under high temperature (50℃ / 30 days), low temperature (-5℃ / 30 days) and light (168 hours) conditions; sample A changed color slightly and had a slight odor after the high temperature stability test, and the ingredient degraded by 2%; samples B and C had no changes in appearance and odor after the stability test, and the ingredient degradation rate was extremely low (<1%).

[0067] From the above, it can be seen that samples A and B show good cleaning ability and bactericidal effect, but may be insufficient in skin mildness or stability. Sample C has the ability to maintain good cleaning ability and bactericidal effect while improving skin mildness and stability.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
