Embodiment Construction

[0011] The present invention is a kind of preparation method of improved water-free hand sanitizer, each component of this water-free hand sanitizer is: ethanol, carbomer (carbomer), deionized water, aminomethyl propanol, propylene glycol, triclosan ( triclosan), glycerin. The present invention assembles above-mentioned each component according to following steps:

[0012] (1) Stir and heat carbomer and deionized water in a vacuum turbo mixer at 40-45°C until completely dispersed. Then the temperature was lowered, ethanol was added, and the mixture was stirred for 5 minutes. Then add aminomethyl propanol to adjust the pH value of the solution to between 6 and 7. This phase A reactant is rotated rapidly with the blades of the vacuum turbo mixer.

[0013] (2) In another mixer, triclosan is added to propylene glycol to fully dissolve and become phase B reactant. Pour phase B reactants into phase A reactants and mix in vacuum turbo mixer for 5 minutes with vacuum turbo mixer r...

Abstract

An improved hand-washing liquid without water is prepared from alcohol, carbomer, deionized water, aminomethyl propanol, propanediol, triclosan and glycerin proportionally through mixing carbomer with deionized water, stirring while heating, cooling, mixing with alcohol, adding aminomethyl propanol to obtain phase A, high-speed stirring, mixing it with the mixture of triclosan and propanediol while stirring, slow stirring, and adding glycerin.

Description

technical field [0001] The invention relates to a hand sanitizer, in particular to a preparation method of an improved water-free hand sanitizer. Background technique [0002] Chinese patent document CN1596877A discloses a kind of water-free disinfectant hand sanitizer and its preparation method. In the hand sanitizer, ethanol, tea tree oil, carbopol, cosolvent, moisturizing agent and other components are mainly combined, and each group is weighed according to the formula ratio. First add pure water accounting for 20% of the total weight of the hand sanitizer into the stainless steel reaction pot with a cover, slowly add carbopol to the pure water in 3 to 5 times, stir while adding, at 80 to 100 rpm Mechanically stir at a speed of 150 minutes for 150 minutes, fully disperse to obtain a uniform turbid dispersion, let stand overnight, fully swell, and obtain liquid A. Add 10% ethanol to the total weight of the hand sanitizer in another stainless steel reaction pot with a cove...
