Embodiment 1

[0055] 1) Weigh 0.10g eugenol, 0.77g isopropyl myristate, 0.15g jojoba oil, 0.08g vitamin E oil, Tween-805.83g, Span-801.17g, deionized water 91.90g g, standby;

[0056] 2) At room temperature of 25°C, first place the weight of isopropyl myristate, jojoba oil, vitamin E oil, Tween-80 and Span-80 on a constant temperature magnetic stirrer and stir at 300rpm 10min, mix well;

[0057] 3) Slowly add deionized water dropwise to the mixture, and stir while adding dropwise. At the beginning, the viscosity of the system is small. As the amount of water increases, the system will become viscous. At this time, the system may appear liquid crystal phase or oil-in-water nanoemulsion. Continue to add drops and stir continuously. When the amount of water reaches 24.00g, The system will suddenly become thinner. At this time, the O / W nanoemulsion is produced. Add deionized water to 91.90g to prepare a clear and transparent O / W type nanoemulsion, and finally add the eugenol of the stated wei...

Embodiment 2

[0059] 1) Weigh 4.62g of isopropyl myristate, 0.92g of jojoba oil, 0.46g of vitamin E oil, 1.67g of Tween-8011.67g, 2.33g of Span-802.33g of each drug component, 85.00g of deionized water, and 5.00g of eugenol g, standby;

[0060] 2) At room temperature of 25°C, first place the weight of isopropyl myristate, jojoba oil, vitamin E oil, Tween-80 and Span-80 on a constant temperature magnetic stirrer and stir at 300rpm 10min, mix well;

[0061] 3) Slowly add deionized water dropwise to the mixture, and stir while adding dropwise. At the beginning, the viscosity of the system is small. As the amount of water increases, the system will become viscous. At this time, the system may appear liquid crystal phase or oil-in-water nanoemulsion. Continue to add drops and stir continuously. When the amount of water reaches 21.00g, The system will suddenly become thinner. At this time, the O / W nanoemulsion will be produced. Add deionized water to 85.00g to prepare a clear and transparent O / ...

Embodiment 3

[0063] 1) Weigh each drug component isopropyl myristate 15.38g, jojoba oil 3.08g, vitamin E oil 1.54g, Tween-8037.50g, Span-807.50g, ionized water 25.00g, eugenol 10.00g ,spare;

[0064] 2) At room temperature of 25°C, first place the weight of isopropyl myristate, jojoba oil, vitamin E oil, Tween-80 and Span-80 on a constant temperature magnetic stirrer and stir at 300rpm 10min, mix well;

[0065] 3) Slowly add deionized water dropwise to the mixture, and stir while adding dropwise. At the beginning, the viscosity of the system is small. As the amount of water increases, the system will become viscous. At this time, the system may appear liquid crystal phase or oil-in-water nanoemulsion. Continue to add drops and stir continuously. When the amount of water reaches 12.00g, The system will suddenly become thinner. At this time, the O / W nanoemulsion is produced. Add deionized water to 25.00g to prepare a clear and transparent O / W type nanoemulsion, and finally add the eugenol ...

Abstract

The invention discloses the eugenic nanometer drug, comprising isopropyl microstate, croton oil, vitamin E oil, tuwen-80, spans-80 and eugenic. The drug has the advantages of improving the antibiosis, anti-inflammation, disinfection, analgesic, and ant parasitic. So the drug is green, safe and highly effective ant parasitic agent.

Description

technical field [0001] The invention belongs to the field of veterinary medicine, and relates to a medicine with antibacterial and anti-inflammatory properties, insecticidal and anthelmintic repellent, antipyretic and analgesic properties, and anti-animal parasite, in particular to a eugenol nanoemulsion medicine and a preparation method thereof. Background technique [0002] Eugenol (Eugenol) is a light yellow or colorless clear oily compound with aroma, and it is a good plant-derived medicine. Eugenol has a wide range of pharmacological effects, mainly antibacterial and anti-inflammatory, anti-corrosion and fresh-keeping, insecticidal and anthelmintic, antipyretic and analgesic, and anti-animal parasites. Because eugenol is a volatile oil, it is extremely difficult to dissolve in water, has poor stability, and is easy to lose during the production and storage of traditional preparations and affect the efficacy of the medicine. It is a technical problem to be solved in the ...
