Description

Essential oil hand sanitizer and preparation method thereof

Technical field

The invention relates to the technical field of daily necessities, and relates to an essential oil hand sanitizer and a preparation method thereof.

technical background

Current hand sanitizers usually use a certain amount of chemical components as the antibacterial ingredients of hand sanitizers. Using these hand sanitizers only removes bacteria and dirt on the surface of the skin of the hands, and cannot achieve a long-lasting antibacterial effect. This is The shortcomings of hand sanitizers currently on the market. With the progress and development of society, people's daily living standards continue to improve, and their requirements for detailed supplies are getting higher and higher. In the process of using hand sanitizer, people not only require it to be able to remove dirt and scale, but also hope to have a long-lasting cleaning effect. Antibacterial function.

The main function of hand sanitizer is to clean and protect skin. Some specific ingredients can disinfect and sterilize, such as Escherichia coli, Staphylococcus aureus, Streptococcus, etc. However, counterfeit products can cause damage to the skin of the hands after washing. larger. There are many types of hand sanitizers, such as: ordinary hand sanitizer, which only has the function of cleaning and decontamination; disinfectant hand sanitizer, which has antibacterial, bacteriostatic or sterilizing effects; heavy oil stain hand sanitizer, which is used for industrial oil stains (machine oil, gasoline, Butter, diesel, etc.) and stubborn stains.

Hand sanitizer directly faces the skin and is applied directly to the skin, so the pH has higher requirements and cannot be alkaline or acidic. In addition, hand sanitizers generally do not contain phosphorus, aluminum, alkali, sodium alkyl benzene sulfonate and other ingredients.

Certain traditional Chinese medicine ingredients can inhibit the formation of bacterial cell membranes and increase the sensitivity of bacteria to antibacterial and antibacterial ingredients by increasing the conductivity of bacteria, changing the structure of bacterial cell membrane proteins, thereby changing the permeability of bacterial cell membranes, and destroying bacterial cell wall structures. Inhibit bacterial respiratory metabolism and inhibit the adhesion of pathogenic bacteria to achieve antibacterial and bacteriostatic purposes. It uses pure plant-derived ingredients without adding additional preservatives. It is natural and environmentally friendly, safe, non-irritating, and has no toxic side effects. It not only ensures the antibacterial and antibacterial activity, but also ensures the stability of the hand sanitizer itself, and has a good moisturizing and moisture-absorbing effect.

Eucalyptus leaf is a commonly used Chinese herbal medicine in southern China. Eucalyptus leaf oil has antibacterial, anti-inflammatory, antioxidant and local anesthetic effects. The main components of eucalyptus leaf volatile oil are 3-carene, α-terpineol, (-)glomerol, D-terpene, 1-terpineol, etc., which can be used to treat influenza, upper respiratory tract infections, pneumonia, Coughs and skin diseases. Artemisia annua oil has antibacterial, anticancer, antiviral, anti-inflammatory, mosquito repellent, insecticidal, antioxidant and other activities.

In the present invention, eucalyptus essential oil and artemisia annua oil are added to the hand sanitizer at the same time, and polyvinylpyrrolidone k32 (hereinafter referred to as PVPk32), poloxamer 407, and decaglycerol are used as emulsifiers, so that poloxamer 407 astringes the skin. In order to improve the antibacterial effect of hand sanitizer and increase the antibacterial rate of hand sanitizer, it can effectively improve the hygiene, health and skin care purposes of hand sanitizer. There are currently no scientific research reports on this method, and there is no information on the use of such technology in production.

Contents of the invention

The present invention mainly provides an essential oil hand sanitizer and a preparation method thereof to solve the technical problems raised in the above background technology.

The technical solutions adopted by the present invention to solve the above technical problems are:

An essential oil hand sanitizer and its preparation method, characterized in that it consists of the following ingredients in parts by weight: 1-6 parts of eucalyptus oil, 1-6 parts of artemisia annua oil, 321-4 parts of PVPk, and poloxamer 4071 -6 parts, 1-4 parts of polyglycerol, 100-400 parts of water.

Preferably, 3 parts of eucalyptus oil, 3 parts of artemisia annua oil, 1 part of PVPk32, 1 part of poloxamer 407, 1 part of decalycerol, and 150 parts of water.

The water used in the present invention is all deionized water.

Eucalyptus oil and Artemisia annua oil have a synergistic bactericidal effect. The addition of poloxamer 407 as an emulsifier also enhances the bactericidal effect. The emulsifiers used in the present invention are PVPk32, poloxamer 407, and decapolyglycerol. The combined use of these three as emulsifiers is the first invention of the present invention. While serving as an emulsifier, poloxamer 407 also has an astringent effect. Together with eucalyptus The sterilization effect is better when used with Artemisia annua oil.

Detailed ways

1. Weigh the eucalyptus oil, artemisia annua oil, PVPk32, poloxamer 407, ten polyglycerol and water according to the weight parts in Table 1.

2. In the mixing kettle, first add water and heat to 70-80°C. Under stirring conditions, add PVPk32, poloxamer 407 and decapolyglycerol, cool to 30-40°C, then add eucalyptus oil and Artemisia annua oil, stir evenly to obtain the essential oil hand sanitizer of the present invention.

Table 1 Formulas of various examples and comparative examples (parts by weight)

It can be seen from Table 1 that the emulsions obtained in Examples 1 to 5 and Comparative Examples 1 and 2 did not stratify after being placed for 2 years. The emulsions obtained in Comparative Examples 3 and 4 without adding PVPk32 or Poloxamer 407 were unstable and separated after 1 day and 15 days respectively. Comparative Example 5 without adding any emulsifier separated into oil and water.

Antibacterial effect test

In accordance with the industry standard QB/T2850-2007 antibacterial and bacteriostatic detergents, the antibacterial effect was tested. The action concentration was 1wt% and the action time was 15 minutes. The specific test data are shown in Table 2.

Table 2 Antibacterial effect test table of essential oil hand sanitizer

It can be seen from Table 2 that compared with the comparative examples, since eucalyptus oil and artemisia annua oil were added in Examples 1-5, only one essential oil was added in Comparative Examples 1 and 2, and only one of them was added in Comparative Examples 3-5. Either or without adding poloxamer 407, the bactericidal effect of the embodiment is better than that of the comparative example. Eucalyptus oil and Artemisia annua oil have a synergistic bactericidal effect, and poloxamer 407 is added as an emulsifier.
