DETAILED DESCRIPTION

[0017] The embodiments of the present application provide a preparation method of massage essential oil, which can obtain massage essential oil with stable and uniform component distribution during long-term storage. The preparation method of massage essential oil of the present embodiment is especially suitable for the preparation of massage essential oil with mixed base oil and mixed single essential oil, which can avoid the problem of uneven distribution of components caused by sinking or floating of different components when essential oil components with different densities and different mutual solubilities are mixed.

[0018] Specifically, the preparation method of the present embodiment includes the following steps: Step one: prepare raw materials, including base oil 500 parts by mass, single essential oil 13-16 parts by mass, xanthan gum 1-2 parts by mass, hyaluronic acid 0.5-1 parts by mass, isopropyl myristate 1-3 parts by mass; wherein the base oil is a mixture of coconut oil, jojoba oil and sweet almond oil, and the single essential oil is a mixture of coffee essential oil, sandalwood essential oil, frankincense essential oil and cedar essential oil; Step two: stir the single essential oil, xanthan gum and hyaluronic acid under heating conditions at a first rotation speed, then stir at a second rotation speed at room temperature, and then stand under cooling conditions, and after returning to room temperature, stir at a third rotation speed to obtain an essential oil mixture; the second rotation speed is less than the first rotation speed, and the third rotation speed is less than the second rotation speed; Step three: stir the essential oil mixture, base oil and isopropyl myristate at room temperature at a fourth rotation speed to obtain a massage essential oil; the fourth rotation speed is less than the third rotation speed.

[0019] In step one, the mixture of coconut oil, jojoba oil and sweet almond oil is used as the base oil as the basic carrier of the massage essential oil, with the highest proportion, mainly to dilute the single essential oil, reduce the irritation of the single essential oil, at the same time, provide nourishment and moisturizing for the skin, enhance the spreadability of the essential oil, facilitate the application and push during massage, and also help the penetration of nutrients into the skin. The mixture of the three oils can combine the characteristics of easy absorption of coconut oil, strong stability of jojoba oil and mild and skin-friendly sweet almond oil.

[0020] The single essential oil adopts a mixture of coffee essential oil, sandalwood essential oil, frankincense essential oil and cedar essential oil, which is the functional core component of the massage essential oil. Coffee essential oil can refresh the mind, promote blood circulation and boost mood; sandalwood essential oil can calm, anti-inflammatory, antibacterial and promote skin healing; frankincense essential oil can calm and pacify the nerves, promote healing, soothe inflamed skin and fight acne bacteria; cedar essential oil can calm, reduce pressure, promote lymph circulation and improve edema. The above single essential oil combined with massage techniques can have the effects of calming, reducing swelling, reducing redness, detoxifying, unblocking lymph and the like.

[0021] The combination of xanthan gum and hyaluronic acid can play a stabilizing role, forming intermolecular forces with each single essential oil component, preventing stratification of each component, making the composition of essential oil more uniform, and enhancing the stability of the formula.

[0022] Isopropyl myristate has lubricating and penetration promoting effects, can reduce the gel feeling of essential oil, promote the spread of essential oil, and at the same time help the base oil and single essential oil to penetrate the skin better, enhance the absorption efficiency.

[0023] Step two, the single essential oil, xanthan gum, hyaluronic acid are first heated and stirred rapidly, so that the single essential oil is fully dispersed and mixed evenly with other ingredients, then stirred at room temperature, which is conducive to the full contact of xanthan gum and hyaluronic acid with the single essential oil and the formation of intermolecular forces, and enhances the compatibility. Subsequent low-temperature standing can make the intermolecular interaction more stable.

[0024] Step three, the essential oil mixture is stirred with base oil and isopropyl myristate at low speed, so that all components are fully integrated. The base oil serves as the main body to disperse other ingredients, and the isopropyl myristate adjusts the overall texture, finally forming a uniform, stable and suitable viscosity essential oil product. Low-speed stirring can avoid damaging the stable structure formed in the early stage, ensuring the long-term stability of the product.

[0025] In some examples, the raw materials include 500 parts by mass of base oil, 13-15 parts by mass of single essential oil, 1-1.5 parts by mass of xanthan gum, 0.5-0.6 parts by mass of hyaluronic acid, and 2-3 parts by mass of isopropyl myristate. When each component is within the above range, the uniformity and stability of the massage essential oil can be further improved.

[0026] In some examples, in the base oil, the mass ratio of coconut oil, jojoba oil and sweet almond oil is 1:(2-3):(4-5) to obtain the desired spreadability and delicate feel.

[0027] In some examples, in the single essential oil, the mass ratio of coffee essential oil, sandalwood essential oil, frankincense essential oil and cedar essential oil is 1:(0.5-1):(0.3-0.5):(0.3-0.5) to obtain the desired efficacy.

[0028] In some examples, in step two, the single essential oil, xanthan gum and hyaluronic acid are stirred at 40-50°C at a speed of 300-500 rpm for 5-10 min, then stirred at room temperature at a speed of 200-300 rpm for 30-60 min, then placed at 0-5°C for 1-2 h, and then stirred at 100-200 rpm for 10-20 min after returning to room temperature to obtain the essential oil mixture.

[0029] In some examples, in step two, the single essential oil, xanthan gum and hyaluronic acid are stirred at 40-45°C at a speed of 300-400 rpm for 6-8 min, then stirred at room temperature at a speed of 200-250 rpm for 40-60 min, then placed at 0-5°C for 1-1.5 h, and then stirred at 100-150 rpm for 10-15 min after returning to room temperature to obtain the essential oil mixture.

[0030] In some examples, in step three, the essential oil mixture, base oil and isopropyl myristate are stirred at room temperature at a rotation speed of 50-100 rpm for 20-30 min to obtain the massage essential oil.

[0031] In some examples, in step three, the essential oil mixture, base oil and isopropyl myristate are stirred at room temperature at a rotation speed of 80-100 rpm for 20-25 min to obtain the massage essential oil.

[0032] In some examples, in step three, after the essential oil mixture, base oil and isopropyl myristate are stirred at room temperature at the third rotation speed, the obtained product is further placed at room temperature for 1-1.5 h, and then filtered with a 40-80 mesh filter screen to remove a small amount of insoluble substances to obtain the massage essential oil.
