Preparation method of hand-washing-free disinfection preparation

[0032] Preparation of hand sanitizer preparations:

[0033] (1) Preparation of chemical disinfection components: respectively dissolve 4 g of chlorhexidine gluconate and 4 g of benzalkonium chloride in ethanol to form a saturated solution at 25 ° C, then mix the saturated solution at a speed of 300 r / min for 5 min to obtain chemical disinfection Element;

[0034] (2) Preparation of plant disinfection components: 12g Kudingcha extract, 10g dandelion extract, 8g purslane extract and 5g Scutellaria baicalensis extract were mixed for 10min at a rotating speed of 300r / min to obtain plant disinfection components;

[0035] (3) Preparation of hand-free disinfection preparation: add above-mentioned 8g chemical disinfection composition and 10g plant disinfection composition to 30g aloe vera gel, and add 50g deionized water, mix 15min under rotating speed 300r / min (observe plant after mixing 15min The colored substance in the disinfectant composition is uniformly dispersed in the alo
