preparation example Construction

[0035] The invention provides the preparation method of the aforementioned nano-silver antibacterial hand sanitizer, which comprises the following steps: according to mass ratio, mixing and dissolving water with lauryl sulfate, fatty alcohol ether sulfate and lauroyl sarcosinate and then adding moisturizing skin care agent, viscosity regulator, nano-silver antibacterial agent, stabilizer and pH regulator in sequence to obtain the nano-silver antibacterial hand sanitizer.

[0036] Specifically, the process steps of the preparation method described in the embodiment of the present invention are:

[0037] Water (usually deionized water) is added to the reactor, preferably heated to 40-80° C., sodium lauryl sulfate, sodium fatty alcohol ether sulfate, sodium lauroyl sarcosinate are added, and stirring is started until the dissolution is complete.

[0038] When the temperature is cooled to room temperature, it is preferable to add moisturizing skin care agent, viscosity modifier an...

Embodiment 1

[0043] 64.1kg of deionized water was added to the reactor, 5kg of sodium lauryl sulfate, 10kg of sodium aliphatic alcohol ether sulfate, 10kg of sodium lauroyl sarcosinate were added after being warming up to 70°C, and the stirring was started until the dissolution was complete. After the temperature was cooled to room temperature, 2kg of propylene glycol, 2kg of hyaluronic acid, 2kg of carbomer and 0.5kg of jasmine essence were added in sequence, and stirred until completely dissolved. After dissolving completely, add 2kg of nano-silver antibacterial agent, 1kg of glycerol, and 1kg of ascorbic acid to the reaction kettle, add 0.4kg of lactic acid after stirring for 30 minutes, stir evenly to make pH 5-6, and obtain 100kg of finished product.

Embodiment 2

[0045] 72.4kg of deionized water was added to the reactor, and 5kg of sodium lauryl sulfate, 8kg of sodium aliphatic alcohol ether sulfate, and 7kg of sodium lauroyl sarcosinate were added after being warming up to 75° C., and stirring was started until the dissolution was complete. After the temperature was cooled to room temperature, 2kg of propylene glycol, 1kg of coconut oil, 2kg of carbomer and 0.3kg of lavender essence were added successively, and the mixture was stirred until it was completely dissolved. After the dissolution is complete, add 1kg of nano-silver antibacterial agent and 1kg of glycerol into the reaction kettle, stir for 30 minutes and then add 0.3kg of citric acid, stir evenly so that the pH is 5-6, that is, 100kg of finished products are obtained.

Abstract

The invention provides a nano-silver antibacterial hand sanitizer and a preparation method thereof.The antibacterial hand sanitizer is prepared from, by mass, 5%-25% of a mixed surfactant, 0.1%-5% of a moisturizing skin care agent, 0.025%-2% of a nano-silver antibacterial agent, 1%-5% of a stabilizer, 0.5%-5% of a viscosity modifier, 0.1%-0.5% of a pH modifier and the balance water; the mixed type surfactant is a mixture of dodecyl sulfate, fatty alcohol ether sulfate and lauroyl sarcosine salt. The hand sanitizer disclosed by the invention has the advantages of strong decontamination capability, mildness, no irritation, good stability and no need of adding preservatives. Meanwhile, the nano-silver antibacterial agent and the lauroyl sarcosine salt have antibacterial performance and are uniformly dispersed in the hand sanitizer, a synergistic antibacterial effect is generated by combined use of the nano-silver antibacterial agent and the lauroyl sarcosine salt, and the antibacterial effect is excellent and lasting.

Description

technical field [0001] The application belongs to the technical field of daily chemical processing, and in particular relates to a nano-silver antibacterial hand sanitizer and a preparation method thereof. Background technique [0002] In people's daily life, the hands are easily exposed to dirt and bacteria. Only using water or ordinary hand sanitizer cannot completely remove the bacteria on the surface of the hands, and it will still cause harm to the human body. Frequent hand washing has become a consensus among people at present, and the use of antibacterial hand sanitizer can effectively prevent the spread of bacteria and viruses. Antibacterial hand sanitizer is gradually accepted by people due to its strong antibacterial properties and convenient use. [0003] At present, most of the antibacterial hand sanitizers on the market use organic antibacterial agents as the main sterilization ingredients, and add a large amount of anionic surfactants. However, when the organ...
