Description

Technical Field

[0001] The invention relates to a preparation method of a natural antibacterial, moisturizing and skin-care hand soap based on clove oil, belonging to the technical field of hand soap production. Background Art

[0002] Hand sanitizer is a daily cleaning product with a wide variety of products, but most of the current hand sanitizers contain certain chemically synthesized ingredients. Excessive contact with non-natural surfactants, organic solvents, etc. can easily irritate the skin and cause allergies. Some hand sanitizers can make the skin feel dry and uncomfortable after washing, which can also have a certain impact on human health.

[0003] In the prior art, there are antibacterial skin care hand sanitizers with certain biomass raw materials. For example, Chinese patent CN105616285A discloses a method for preparing a bactericidal skin care hand sanitizer, which contains biomass raw materials such as clove oil, but the total composition is complex and not all-natural biomass materials. For example, Chinese patent CN108721126A discloses an antibacterial hand sanitizer, which has too many ingredients and has a certain antibacterial effect, but the skin feel is poor.
