Abstract

The invention provides a compound antibacterial aerosol. The compound antibacterial aerosol is prepared from the following raw material components: 17.5 to 23.5 parts of chitosan quaternary ammonium salt, 0.9 to 4.7 parts of emulsifier, 37.1 to 54.9 parts of distilled water, 20.5 to 45.9 parts of propellant, 1.3 to 3.5 parts of sodium chloride, 0.1 to 1.2 parts of potassium chloride, 3.5 to 7.5 parts of dry tea leaves, 1.5 to 2.9 parts of vitamin C and 1.9 to 3.1 parts of sodium higher fatty acid; the emulsifier is one of Arabic gum, soybean phospholipid or fatty glyceride; the concentration of hydrogen peroxide is 0.1 to 5 percent; chitosan diquaternary ammonium salt, the vitamin C and sodium chloride all have good antibacterial properties; by combining the three substances to achieve theantibacterial effect of wound, wound infection can be prevented and controlled while antibacterial and anti-inflammatory properties are achieved; the chitosan diquaternary quaternary ammonium salt, the hydrogen peroxide and the sodium chloride have good sterilization effects on the skin surface; the compound antibacterial aerosol has the advantages of simple preparation, short production cycle and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of aerosols, in particular to a composite antibacterial aerosol. Background technique [0002] Chitosan, a natural polymer, has excellent properties such as biocompatibility, non-toxicity, antibacterial activity, and microbial degradability. The current research on the modification of chitosan is mainly to introduce a quaternary ammonium salt structure on the C2-NH2 group. , this chemically obtained chitosan quaternary ammonium salt has good biocompatibility, not only has good water solubility, antibacterial, film-forming, cationic adsorption, moisture absorption, flocculation and anti- It also has excellent properties such as non-toxic, safe, bactericidal and antibacterial, and biodegradable, and its antibacterial properties are much better than chitosan and other chitosan derivatives. These excellent properties make chitosan double Quaternary ammonium salts are widely used in medicine, bioengineering, foo...
