Description

Technical Field

[0001] The invention relates to a method for preparing a natural antibacterial, skin-protecting and insect-repellent super-fat soap based on clove oil, and belongs to the technical field of soap production. Background Art

[0002] Conventional soaps generally only have a single function of cleaning. Currently available antibacterial soaps generally rely on the addition of chemical synthetic antibacterial agents to achieve their antibacterial properties, which is not suitable for pregnant women and some sensitive skin. Carboxymethyl chitosan, which exists in chitin in the biological world, has a natural antibacterial function and is widely used in clinical practice. Its safety is recognized. In addition, it has moisturizing and skin repair functions. Sodium humate is the sodium salt of humic acid and is a natural high molecular organic compound. In the field of daily chemicals, it has been proven to have antibacterial, moisturizing and antioxidant functions, and can effectively reduce skin inflammation and allergic reactions and improve skin texture. For example, Chinese patent CN109576095A discloses a method for preparing sodium humate soap, but the antibacterial rate of the soap prepared is only 95%. Clove oil has antibacterial and anti-inflammatory effects, is rich in antioxidant ingredients, and has a certain insecticidal effect; Chinese patent CN117603770A discloses a method of encapsulating eucalyptus oil and clove oil into an essential oil inclusion complex to prepare an antibacterial and insect repellent soap, but there is also a problem that the antibacterial effect is not outstanding. Summary of the invention

[0003] [Technical issues]

[0004] Most traditional soaps use chemical synthetic antibacterial agents, which are not suitable for use by pregnant women and people with sensitive skin. Most antibacterial soaps feel dry and hard, have poor antibacterial effects, have relatively simple functions, and have no skin repair, anti-inflammatory, or insect repellent effects.
