Abstract

The invention provides a non-rinse bacteriostatic hand sanitizer and a preparation method thereof. The non-rinse hand sanitizer comprises the following raw materials by weight percentage: 0.5-0.8% of carbomer resin-U20, 1-3% of a moisturizing agent, 1-2% of a tea tree extracted liquid, 1-2% of a skin care agent, 65-69% of anhydrous ethanol, 0.8-1.2% of a surfactant, 0.4-0.8% of triethanolamine, 0.3-0.7% of essence, and the balance deionized water. According to the invention, the components are mixed according to certain order to obtain the non-rinse hand sanitizer. With the formula, the non-rinse bacteriostatic hand sanitizer can have a good inhibition effect on Escherichia coli and Staphylococcus aureus, and has good stability, is mild and non-irritating, has moisturizing and skin care efficacy, is free from rinse and convenient for carrying outside, and saves water.

Description

technical field [0001] The invention relates to a hand sanitizer, in particular to a rinse-free antibacterial hand sanitizer and a preparation method thereof. Background technique [0002] Tea tree extract is extracted from the fresh branches and leaves of Melaleuca alternifolia, a shrub species of Melaleuca alternifolia. Because of its broad antibacterial spectrum and strong antibacterial activity, it has a good inhibitory effect on common bacteria such as Staphylococcus aureus, Escherichia coli, and Bacillus subtilis, and is also used to treat related diseases caused by fungi, bacteria, or viruses (such as Acne, ringworm, cold sores, oral candidiasis, etc.), is expected to be developed as a natural antibacterial agent that can alleviate the global "antibacterial drug crisis". [0003] At present, the ethanol content of general no-rinse hand sanitizers on the market is about 75%, and high-concentration ethanol can irritate the skin. In addition, the bactericidal components...
