Problems solved by technology

However, due to the complex composition of plant essential oils, the solubilizing effects of the same solubilizer on different essential oils are quite different.
For example, using Tween 20 can solubilize mint essential oil very well, making its water solvent achieve a clear and transparent effect, but it cannot make lemon essential oil and tea tree essential oil achieve the same solubilizing effect

Embodiment 1

[0038] Weigh 0.15 grams of cinnamon essential oil, 0.15 grams of litsea cubeba essential oil, 0.05 grams of lemon essential oil, 0.05 grams of thyme essential oil, 0.05 grams of peppermint essential oil, and 0.05 grams of tea tree essential oil into a 100 ml glass beaker. Add 3 grams of fatty alcohol polyoxyethylene ether 7 and 2.5 grams of absolute ethanol into the beaker. Stir the above essential oil, absolute ethanol and solubilizer evenly with a glass rod. Continue to add 25 grams of distilled water to the beaker. An electric stirrer was used to stir the above aqueous solution for 5 minutes at normal temperature to obtain a clear and transparent essential oil water solvent.

Embodiment 2

[0040] Weigh 2 grams of cinnamon essential oil, 1 gram of litsea cubeba essential oil, 0.5 gram of lemon essential oil, 0.5 gram of thyme essential oil, 0.5 gram of peppermint essential oil, and 0.5 gram of tea tree essential oil into a 500 ml glass beaker. Add 25 grams of fatty alcohol polyoxyethylene ether 7 and 25 grams of absolute ethanol in the beaker. Stir the above essential oils, absolute ethanol and solubilizer evenly with an electric mixer. Continue to add 195 grams of distilled water to the beaker. An electric stirrer was used to stir the above aqueous solution for 10 minutes at normal temperature to obtain a clear and transparent essential oil water solvent.

Embodiment 3

[0042]In this example, the antibacterial effect of the water solvents made from the individual essential oils included in the compound essential oils of the present invention was measured. At the same time, a water solvent containing no essential oil but containing ethanol and fatty alcohol polyoxyethylene ether 7 was used as a control group.

[0043] Preparation of essential oil water solvent: weigh 2 grams of cinnamon, litsea cubeba, tea tree, lemon, peppermint, and thyme essential oils and add them to a 500 ml glass beaker. Add 12 grams of fatty alcohol polyoxyethylene ether 7 and 10 grams of absolute ethanol to the beaker. Stir the above essential oil, absolute ethanol and fatty alcohol polyoxyethylene ether 7 evenly with a glass rod. Continue to add 76 grams of distilled water to the beaker. An electric stirrer was used to stir the above aqueous solution for 10 minutes at normal temperature to obtain a clear and transparent essential oil water solvent.

Abstract

The invention discloses a plant essential oil aqueous solvent with an air purification effect and a preparation method thereof. The plant essential oil aqueous solvent is composed of, by weight, the following components: 1-2 parts of plant essential oil, 3-12 parts of fatty alcohol polyoxyethylene ether 7, 2-12 parts of absolute ethyl alcohol, and 74-94 parts of distilled water. Wherein the plantessential oil is composed of 20-40 parts of cinnamon essential oil, 20-40 parts of Litsea cubeba essential oil, 5-15 parts of thyme essential oil, 5-15 parts of peppermint essential oil, 5-15 parts ofMelaleuca alternifolia essential oil, and 5-15 parts of lemon essential oil. A preparation process of the plant essential oil aqueous solvent includes the following steps: first adding the parts by weight of plant essential oil, fatty alcohol polyoxyethylene ether 7, and ethyl alcohol to a container and uniformly mixing, then adding the parts by weight of distilled water, and stirring until beingclear and transparent. The plant essential oil aqueous solvent can be used to purify air by spreading the plant essential oil aqueous solvent into the air by a spraying or aromatherapy manner. The prepared essential oil aqueous solvent is clear and transparent in appearance, smells fragrant, and can also play the role of refreshing the air.

Description

technical field [0001] The invention relates to a plant essential oil water solvent composition and a preparation method thereof, belonging to the technical field of air purifiers. Background technique [0002] At present, people spend 57% and 75% of the 24 hours a day on average during work and holidays in the indoor environment, so indoor air quality is one of the factors that cannot be ignored that affect people's health. The number of bacteria in the air is an important indicator of air quality. Excessive bacteria in the indoor air will not only irritate the eyes of the human body, cause allergies to the skin and respiratory system, but also may make people feel uncomfortable all over the body, resulting in symptoms such as headache, chest pain, cough, and diarrhea. Certain bacteria in the air may also cause a variety of respiratory infectious diseases when the body's immunity is low. It can be seen that controlling the number of bacteria in the indoor air within a cer...
