Problems solved by technology

[0003] However, in the process of using pure tea tree oil, problems such as high irritation, rapid volatilization, decreased efficacy, and flammability of tea tree oil will be encountered. At the same time, because it is insoluble in water, this greatly limits the scope of use of tea tree oil.

Embodiment 1

[0027] (1) Add tea tree oil into the reaction kettle;

[0028] (2) Add the emulsifier, antibacterial agent, and defoamer to the tea tree oil respectively, heat to 30°C, and under the action of an emulsifier, the emulsification temperature is 30°C, the stirring time is 10min, and the stirring speed is 2000rpm;

[0029] (3) Dissolve the essence in water, heat it to 30°C, and slowly add it to the above mixture. Under the action of an emulsifier, the emulsification temperature is 30°C, the stirring time is 10 minutes, and the stirring speed is 2000rpm to obtain water-soluble tea tree oil.

[0030] The ratio is as follows: (unit: kg)

[0031]

Embodiment 2

[0033] The difference between this example and Example 1 is: step (2) (3) emulsification temperature 40°C, stirring time 20min, stirring speed 8000rpm, others are as follows: (unit: kg)

[0034]

Embodiment 3

[0036] The difference between this example and Example 1 is: step (2) (3) emulsification temperature 60°C, stirring time 30min, stirring speed 15000rpm, others are as follows: (unit: kg)

[0037]

[0038] Three kinds of water-soluble tea tree oil performance effects in the embodiment

[0039]

[0040] Described floating layer height experiment is, respectively get experimental sample 5mL, centrifuge 10min under the rotating speed of 1000r / min, compare the pros and cons of stability according to the number of the top floating layer that comes out, the less top floating layer is more stable. it is good.

[0041] The sample deterioration test is to take 100 mL of each experimental sample, expose it to the air for 15 days, and then judge whether it has deteriorated.

[0042] Described diffusivity experiment is to get experimental sample 10mL respectively, will pour into 200ml water, observe whether to become uniform emulsion rapidly, can rapidly become homogeneous emulsion ...

Abstract

The invention discloses water-soluble tea tree oil and a method for preparing the same. The water-soluble tea tree oil comprises from 5.00 to 50.00 parts of tea tree oil, from 1.40 to 6.50 parts of emulsifiers, from 0.05 to 0.20 part of antibacterial agents, from 0.01 to 0.05 part of antifoaming agents, from 0.01 to 0.15 part of essence and from 43.0 to 90.0 parts of water. The method includes (1), adding the emulsifiers, the antibacterial agents and the defoaming agents into the tea tree oil, heating the tea tree oil with the emulsifiers, the antibacterial agents and the defoaming agents until the temperature of the tea tree oil reaches an emulsification temperature, and uniformly stirring the tea tree oil to obtain a mixture; and (2), dissolving the essence in the water, heating the water with the essence so that the temperature of the water reaches an emulsification temperature, slowly adding the water with the essence into the mixture, and uniformly stirring the water and the mixture to obtain the water-soluble tea tree oil. The water-soluble tea tree oil and the method have the advantages that operation is simple, the production cost is low, and the prepared water-soluble tea tree oil is low in volatilization speed, high in efficacy, free of layering, skinning, oil slick and pollution and good in flowability and diffusion performance, is non-toxic, nonflammable, non-explosive, safe, stable and environment-friendly, and can be dissolved in water solution.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a preparation method of water-soluble tea tree oil. Background technique [0002] Tea tree oil, also known as Melaleuca oil, is a colorless or light yellow essential oil obtained by steam distillation from the branches and leaves of Melaleuca alternifolia. The main component is terpineol-4,1,8- Eucalyptol, α-terpinene, γ-terpinene and α-terpineol, among which the content of terpineol-4 is about 30% to 45%. It is generally believed that tea tree oil is one of the natural extracts with the best health care and medical effects found so far. It is sterilizing and antibacterial, preventing bacterial infections of the skin, oral cavity, and urinary system, treating surface wounds, maintaining skin and promoting skin metabolism. Has a unique effect. At present, tea tree oil is widely used in medicine, health care, daily chemical, food, spices and other industries as antisepti...
