Abstract

The invention belongs to the field of articles for daily life and in particular relates to a hand sanitizer. The hand sanitizer is prepared by taking sodium alginate as a film forming base material and chitosan as a raw material of a blended film; a molecular chain of the chitosan has primary amino and a molecular chain of the sodium alginate has carboxyl; under the action of an electrostatic force, a polyelectrolyte film can be formed through positive and negative charge attraction, so that one layer of protection film is formed on skin; by a low molecular weight plasticizer glycerol, a plasticizer molecule and a polymer have a mutual effect, so that a mutual action force between macromolecules is weakened and the hydrogen-bond interaction in the molecules is weakened; the ratio of a crystallization region to an amorphous region of the film is reduced and the water seepage steam penetration rate of the film is improved, so that the loss of moisture in the skin is prevented or alleviated and the wetting property of the skin is kept; rosemary essential oil is added and essential oil molecules exist in the film with a plurality of micro-pores; after active substances with a bacterium-inhibition effect in the essential oil molecules enter the film, the active substances are dispersed to the surface of the film gradually through the micro-pores, so that the antibacterial performance of the surface of the skin is improved.

Description

technical field [0001] The invention belongs to the field of daily chemical products, and in particular relates to a hand sanitizer. Background technique [0002] In people's life, hands are easy to come into contact with bacteria and dirt, and if they cannot be cleaned in time and effectively, it may endanger their health. Especially for special occupational groups such as doctors and nurses, hand hygiene is even more important. As a new type of hand cleaning product, hand sanitizer appeared later than traditional cleaning products such as soap and soap, but it is popular because of its convenient use, saving time and water, avoiding cross-infection, easy storage, and reducing natural consumption. More and more consumers love it. With the improvement of people's quality of life requirements, the product performance requirements for hand sanitizers are also increasing. Not only must the cleanliness be guaranteed, but also certain health benefits, no skin irritation, and fe...
