preparation example Construction
[0076] In a specific embodiment, the preparation method includes: the raw materials used in the preparation are:
[0077] - ectoine;
[0078] - Alcohol components;
[0079] - ester components;
[0080] - the balance of deionized water;
[0081] And based on the above-mentioned raw materials, the oil-phase ectoine inclusion complex is prepared through the following steps:
[0082] - Mix and dissolve ectoine, alcohol components and deionized water evenly to obtain the first phase;
[0083] - Heating the ester component, mixing evenly, to obtain the second phase;
[0084] - Heating the first phase, then mixing it into the second phase, stirring and mixing to obtain the third phase;
[0085] - homogenization of the third phase;
[0086] - Lower the temperature to normal temperature under mechanical stirring and discharge.
[0087] The preparation method according to the present application is also simply referred to below as "two-phase preparation method".

[0110] Preparation example 1 Preparation example using the most ideal conditions
[0111] 1) Weigh 20g ectoine, 5g butanediol, 3g pentanediol, 28.5g deionized water and mix and stir to obtain phase A;
[0112] 2) 27g of jojoba esters, 15g of sunflower seed wax, and 1.5g of green wattle flower wax were heated to 85°C, mixed, dissolved, and stirred to obtain phase B;
[0113] 3) heating phase A to 85°C, adding phase B, stirring and mixing to obtain the third phase;
[0114] 4) under the condition of 85 ℃, the third phase is homogenized, the homogenization speed is 12000rpm, and the homogenization is 3min;
[0115] 5) Under the condition that the rotating speed is 800rpm, mechanically stir to cool down to normal temperature, discharge the material, and obtain a milky white to pale yellow oil wrapped with ectoine.
[0116] The smear was observed under an electron microscope, and the oil-encapsulated ectoine showed a uniform state (see figure 1 ), the particle size analysis repo...
preparation example 2
[0117] Preparation example 2 uses lower ectoine content and higher stirring speed to obtain smaller average particle size
[0118] 1) Weigh 10g ectoine, 7g butanediol, 3g pentanediol, 34g deionized water and mix and stir to obtain phase A;
[0119] 2) 30g of jojoba esters, 14g of sunflower seed wax, and 2g of green wattle flower wax were heated to 90° C., mixed, dissolved, and stirred to obtain phase B;
[0120] 3) heating phase A to 85°C, adding phase B, stirring and mixing to obtain the third phase;
[0121] 4) Under the condition of 80 ℃, the third phase is homogenized, the homogenization speed is 15000rpm, and the homogenization is 5min;
[0122] 5) Under the condition that the rotating speed is 1000rpm, the temperature is lowered to normal temperature by mechanical stirring, and the material is discharged to obtain a milky white to pale yellow oil wrapped with ectoine.
[0123] The smear was observed under an electron microscope, and the oil-coated ectoine was in a unif...
