Problems solved by technology

[0003] Bitter almond is the seed of mountain apricot (Armeniaca vulgaris Lam), and bitter almond oil is rich in vitamin E, linolenic acid, linoleic acid and other nutrients, but it is greasy and insoluble in water, so it is difficult to use directly, so it is very popular in the market. microemulsion with little bitter almond oil

Embodiment 1

[0026] 1) To improve the water solubility of bitter almond oil: add 1 mL of bitter almond oil and 2 mL of hydrogenated castor oil (specifically PEG-40) into a reactor equipped with a thermometer and a magnetic stirrer, mix well, control the temperature and heat at 70°C for 30 min.

[0027] 2) Emulsified bitter almond oil: mix the product from the previous step with non-ionic emulsifier Q-185S at a mass ratio of 3:0.06, melt at 70°C, stir evenly, and then use non-ionic emulsifier: co-emulsifier A co-emulsifier (glycerin) was added at a mass ratio of =0.06:9, then water was added to 100 mL, and homogeneously stirred for 5 min to obtain a clear and transparent microemulsion of bitter almond oil.

Embodiment 2

[0029] 1) To improve the water solubility of bitter almond oil: add 1 mL of bitter almond oil and 8 mL of hydrogenated castor oil (specifically PEG-40) into a reactor equipped with a thermometer and a magnetic stirrer, mix well, control the temperature and heat at 65°C for 40 min.

[0030] 2) Emulsifying Bitter Almond Oil: Mix the product from the previous step with the nonionic emulsifier Q-18D at a mass ratio of 9:0.06, melt at 65°C, stir evenly, and then use nonionic emulsifier:co-emulsifier= A co-emulsifier (glycerin) was added at a mass ratio of 0.06:10, then water was added to 100 mL, and homogeneously stirred for 4 min to obtain a clear and transparent microemulsion of bitter almond oil.

Embodiment 3

[0032] 1) Improve the water solubility of bitter almond oil: Add 1.5mL bitter almond oil and 4mL hydrogenated castor oil (specifically PEG-60) into a reactor with a thermometer and a magnetic stirrer, mix well and control the temperature at 50°C for 50min .

[0033] 2) Emulsified bitter almond oil: mix the product from the previous step with the nonionic emulsifier Q-18F at a mass ratio of 5.5:0.04, melt at 50°C, stir evenly, and then use nonionic emulsifier: co-emulsifier = Add a co-emulsifier (1,3-butanediol) at a mass ratio of 0.04:4, then add water to 100 mL, and stir homogeneously for 3 minutes to obtain a clear and transparent microemulsion of bitter almond oil.

Abstract

The invention provides a preparation method for nonionic bitter almond oil microemulsion. Hydrogenated castor oil is used for improving the water solubility of bitter almond oil and improving the solubility of the bitter almond oil in an aqueous solution in a heating state, then a nonionic emulsifier is used for emulsifying a bitter almond oil mixture, and a fixed amount of de-ionized water is added. The obtained nonionic bitter almond oil microemulsion has the physical and chemical characteristics of clear and transparent appearance, nanometer particles, spontaneous formation and the like, also has the advantages of low toxicity, high safety and the like, and has broader application prospect in the fields of food, medicine, cosmetics and the like.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a preparation method of nonionic bitter almond oil microemulsion. Background technique [0002] Microemulsion was first proposed by Schulman and Hoar in 1943. Its theory and application have developed rapidly and have been widely used in the fields of tertiary oil recovery, washing and decontamination, catalysis, chemical reaction medium and drug delivery. Microemulsions are usually mixed with water, oil and surfactants to form transparent or translucent dispersions spontaneously. Compared with ordinary emulsions, microemulsions have special properties: the interfacial tension is small, usually 10 -5 N / m~10 -9 N / m; micellar particles are very small, with a diameter of about 10nm to 100nm; they are thermodynamically more stable and can form spontaneously without external energy supply, and no stratification occurs after high-speed centrifugation; the appearance is tr...
