Description

Hand sanitizer and preparation method thereof

Technical Field

The invention relates to the technical field of washing daily chemical products, in particular to a hand sanitizer and a preparation method thereof.

Background

In the daily activities of people, hands contact with various things and the adhered stains are various, so that hand washing is the most frequent action in daily sanitary cleaning life of people, and hand washing products are produced at present. However, due to the restrictions of living conditions and markets, perfumed soaps, washing powders and the like are commonly used for washing hands of people before, and although the perfumed soaps, the washing powders and the like can achieve a certain cleaning effect, the perfumed soaps have an irritant effect on the skin, and after long-term use, part of the skin is rough, chapped and peeled.

The hand sanitizer is a common washing product, and is popular with consumers due to the characteristics of convenient use and convenient preservation. The common hand sanitizer can only decontaminate, has limited killing effect on bacteria and viruses, and has the functions of diminishing inflammation and regenerating and repairing skin wounds.

Therefore, aiming at the defects of the hand sanitizer products in the current market, the invention provides a novel hand sanitizer with the functions of sterilization, decontamination, inflammation diminishing and the like.

The invention aims to provide a hand sanitizer and a preparation method thereof, wherein the hand sanitizer has excellent permeability, bactericidal property and cleaning ability, has the anti-inflammatory and regenerative repair capabilities on skin wounds, and solves the problems that the hand sanitizer in the current market only can decontaminate and does not have the functions of sterilization, disinfection, anti-inflammatory and regenerative repair on the skin wounds.

The invention provides a hand sanitizer which is prepared from the following components in percentage by weight:

0.3-0.6% of hydroxypropyl methyl cellulose, 3-6% of sodium alkyl benzene sulfonate, 3-6% of sodium laureth sulfate, 1-4% of coconut oil diethanolamide, 3-6% of water-soluble silicon, 0.1-0.3% of preservative, 0.1-0.3% of essence and the balance of water.

The water soluble silicon is water soluble silicon crystal solution formed by dissolving silicon trioxide in water, and has the chemical characteristics of no radioactivity, no explosiveness, no toxicity, no sterility and the like. The water-soluble silicon element contained in the water-soluble silicon has super-strong permeability, and the water-soluble silicon element has fine molecules of about 0.4 nanometer, so that the water-soluble silicon element can quickly permeate into cells and has extremely strong permeability to skin. The water-soluble silicon element has super-strong bactericidal property and is mainly reflected in having strong instant bactericidal effect on escherichia coli and legionella (gram-negative bacteria). The water-soluble silicon element has super-strong anti-inflammatory power and has the function of strongly preventing the development of cell inflammation. Can quickly diminish inflammation of damaged skin tissues, such as injured wounds, scalds, burns, frostbites and the like, and can quickly relieve pain and quickly recover the damaged tissues by coating the affected parts with the soluble silicon element. The water-soluble silicon element has super strong cleaning power, can quickly decompose greasy dirt residues on hands when the hands are washed by the liquid soap containing the silicon element, and has extremely strong purification and cleaning effects. The water-soluble silicon element has super strong regenerative power, and can repair and activate damaged cell tissues, skin tissues and connective tissues to promote the regeneration of the damaged cell tissues, skin tissues and connective tissues.

The hydroxypropyl methyl cellulose not only has the characteristics of salt resistance, pH stability, water retention property, dimensional stability, excellent film forming property, wide enzyme resistance, dispersibility, cohesiveness and the like, but also has thickening capability and plays a role in thickening in the invention. The hydrophobic main chain of the cellulose thickener molecules contained in the hydroxypropyl methyl cellulose can be associated with the surrounding water molecules through hydrogen bonds, so that the fluid volume of the polymer is increased, the free movement space of particles is reduced, and the viscosity of the system is increased.

The sodium alkyl benzene sulfonate is solid and soluble in water, has active matter content of 30-40%, unsaponifiable matter content of 3%, pH value of about 8, and has the surface activity of cleaning, moistening, foaming, emulsifying and dispersing. Sodium alkyl benzene sulfonate is easy to oxidize, strong in foaming power, high in detergency, easy to compound with various assistants, low in cost, mature in synthesis process and very excellent in anionic surfactant. The sodium alkyl benzene sulfonate has obvious detergency effect on granular dirt, protein dirt and oily dirt, excellent detergency on granular dirt on natural fiber, raised detergency with the raised washing temperature, high protein dirt effect and rich foam.

Sodium laureth sulfate is a white or pale yellow gel paste or a colorless or pale yellow liquid. From the structure, the sodium laureth sulfate belongs to an amphoteric surfactant, but the sodium sulfate group is dominant, so the sodium laureth sulfate belongs to an anionic type, can be dissolved in water and alcohol, has good washing performance and diffusivity, is easy to generate a large amount of foam, and has antistatic property, smoothness, softness and strong detergency.

The coconut oil diethanolamide has good thickening, foam increasing and foam stabilizing properties; has good emulsifying and decontaminating capabilities; the surfactant has good combination and synergistic effect with other surfactants; has the performances of static resistance, rust prevention, corrosion prevention and the like.

The preservative may inhibit the growth of bacteria, fungi, mold and mildew in the hand sanitizer.

The essence has the main function of generating pleasant smell in the hand sanitizer provided by the invention and covering the smell of a product substrate.

The hand sanitizer prepared from the raw materials can remove dirt on hand skin and kill germs on the surface of the skin. Moreover, the hand sanitizer has an anti-inflammatory effect on a wound part of skin, and can promote regeneration of skin tissues and repair damaged skin.

Further, the hand sanitizer is prepared from the following components in percentage by weight:

0.4 to 0.5 percent of hydroxypropyl methyl cellulose, 4 to 5 percent of sodium alkyl benzene sulfonate, 4 to 5 percent of sodium laureth sulfate, 2 to 3 percent of coconut oil diethanolamide, 4 to 5 percent of water-soluble silicon, 0.1 to 0.2 percent of preservative, 0.1 to 0.2 percent of essence and the balance of water.

The hand sanitizer prepared from the components in percentage by weight has the remarkable effects of decontaminating, sterilizing and diminishing inflammation and regenerating and repairing wounded skin.

Further, the preservative is methylisothiazolinone. Methylisothiazolinone is a high-efficiency bactericide, a heat-resistant aqueous preservative, has a good effect on inhibiting the growth of microorganisms, and can inhibit the growth of bacteria, fungi, molds and mildew.

Further, the water is deionized water.

Deionized water refers to pure water from which impurities in the form of ions are removed, and the water quality is more pure.

The invention also provides a preparation method of the hand sanitizer, which comprises the following steps:

s1: dissolving hydroxypropyl methylcellulose in water to obtain a hydroxypropyl methylcellulose solution;

s2: adding sodium alkyl benzene sulfonate into the hydroxypropyl methyl cellulose solution, stirring until the sodium alkyl benzene sulfonate is completely dissolved, adding a sodium hydroxide solution into the mixture, and adjusting the pH value to 6-8 to obtain a mixed solution 1;

s3: adding sodium laureth sulfate into the mixed solution 1, and stirring until the sodium laureth sulfate is dissolved to obtain a mixed solution 2;

s4: adding coconut oil diethanolamide, water-soluble silicon, preservative and essence into the mixed solution 2, and uniformly stirring to obtain the hand sanitizer.

The hydroxypropyl methyl cellulose solution obtained in the step S1 can increase the viscosity of the hand sanitizer. Step S2, sodium alkyl benzene sulfonate is added, so that the hand sanitizer is easy to foam, and protein dirt and oily dirt can be effectively removed; the pH value is adjusted to be alkalescent by adding sodium hydroxide solution, which is beneficial to enhancing the dirt-removing capability of the hand sanitizer because sweat secreted by a human body is acidic, and dirt on skin is acidic generally due to inorganic salt separated out along with the sweat and grease secreted on the skin surface. In step S3, the stirring process of sodium laureth sulfate is performed slowly to prevent the generation of bubbles. Through the step S4, the prepared hand sanitizer not only has the functions of removing dirt, sterilizing and promoting the regeneration of damaged skin, but also has pleasant fragrance.

Further, the step S2 specifically includes:

heating hydroxypropyl methylcellulose solution to 44-46 ℃ in water bath, adding sodium alkyl benzene sulfonate, stirring to completely dissolve, adding 1-3% by mass of sodium hydroxide solution, and adjusting pH to 6-8 to obtain mixed solution 1.

Heating in water bath to 44-46 deg.c is favorable to the fast dissolution of sodium alkyl benzene sulfonate. And adding 1-3% by mass of sodium hydroxide solution to effectively adjust the pH value of the mixed solution 1.

Further, the water-soluble silicon is prepared by the following method:

burning the silicon dioxide at 1650-2000 ℃ for 8-10 hours, and rapidly cooling to form silicon crystals; and combining the silicon crystals with water to prepare the water-soluble silicon.

Using high grade silicon dioxide (SiO)₂) Recovering gasified silicon element component by 1650-2000 deg.C high-temperature physical extraction method and special method of continuous burning for more than 8 hr, neutralizing harmful component, decomposing, and quickly cooling to form soluble crystal (SiO)₃). Soluble crystals (SiO)₃) Combined with water, can be dissolved in water body by 100 percent to form ionic free molecules, namely water-soluble silicon.
