Abstract

The invention relates to the field of hand sanitizers, in particular to a silver nanowire wash-free antibacterial hand sanitizer. The silver nanowire wash-free antibacterial hand sanitizer is preparedby mixing the following raw materials in percentage by weight: 10-75% of ethanol, 0.1-0.5% of a surfactant, 0.1-1% of a thickener, 1-5% of a humectant, 1-25% of a silver nanowire diluent, 0.01-0.5% of a pH regulator, 0.01-2% of tetrahydromethylpyrimidine carboxylic acid, 0.01-3% of a fragrance extracting solution, 0.1-2% of vitamin E and the balance of deionized water. According to the invention,the unique antibacterial effect of the nano-silver is utilized to effectively sterilize; and meanwhile, compared with a traditional silver antibacterial agent, the nano-silver wire diluent has extremely large specific surface area, is easier to be in close contact with pathogenic microorganisms, and has a more obvious antibacterial effect; meanwhile, tetrahydromethylpyrimidine carboxylic acid with bioactivity is added, so that hands are not hurt while bacteria are effectively inhibited and killed; the wash-free function is achieved, and water resources are saved.

Description

technical field [0001] The invention relates to the field of hand sanitizers, in particular to a nano-silver wire wash-free antibacterial hand sanitizer. Background technique [0002] In daily life, people need to frequently use their hands to contact the outside world, so hands are the most easily polluted body parts and an important channel for infectious bacteria. As a skin cleaner for hand washing, hand sanitizer can keep hands clean and hygienic, which is of great significance to disease prevention and protection of health. [0003] At present, hand sanitizers on the market are roughly divided into three categories according to the decontamination effect. One is common common hand sanitizers, which have conventional cleaning and decontamination effects; Function; the third is the hand sanitizer for heavy oil stains, which has the effect of cleaning stubborn industrial stains. At the same time, according to the method of use, it can be divided into flushing type and di...
