Description

Technical Field

[0001] The present invention relates to the technical field of antibacterial products, and more particularly to a soybean unsaturated fatty acid odor-removing, cleaning and antibacterial liquid. Background Art

[0002] Traditional antibacterial and deodorizing cleaners generally have the following problems:

[0003] Irritation and safety risks: Most products rely on chemically synthesized ingredients (such as quaternary ammonium salts and phenolic compounds), which can easily cause skin allergies or respiratory irritation. For example, chlorine-containing disinfectants commonly used in hospitals can damage the skin of medical staff and are environmentally unfriendly.

[0004] Short-lived antibacterial effects: Traditional products often achieve short-term deodorization by sterilizing surfaces, but they cannot prevent bacterial regeneration. For example, pet deodorants require frequent reapplication and can potentially harm pets due to residual ingredients.

[0005] Single function: Existing cleaning agents are often only targeted at specific scenarios (such as home or medical), and it is difficult to meet the needs of multiple fields such as food processing and maternal and child care at the same time.

[0006] The contradiction between moisturizing and deodorizing: Although some antibacterial agents (such as alcohol) can kill bacteria quickly, they will cause dryness of the skin and cannot take into account the moisturizing function.

[0007] Therefore, how to provide a soybean unsaturated fatty acid deodorizing, cleaning and antibacterial liquid that uses pure natural soybean unsaturated fatty acid extract to perform mild antibacterial activities while having high moisturizing properties, antioxidant and anti-inflammatory properties, and deodorizing and odor removal is a problem that technicians in this field urgently need to solve.

[0015] (4) dilution: adding purified water in proportion to dilute the prepared mixed nanoemulsion solution according to the dilution rate;

[0016] (5) Filling: After low-frequency shearing again, the mixed solution is filled into the product container.

[0017] Preferably, the process of extracting and purifying soybean unsaturated fatty acids in step (1) is as follows:

[0018] S1. Raw material pretreatment: remove soybean oil impurities and improve oil purity;

[0019] S2. The soybean oil refining process includes degumming, deacidification, decolorization, and deodorization;

[0020] S3. Preparation of unsaturated fatty acids from soybeans (ester exchange method);
