preparation example Construction

[0036] The present invention provides the preparation method of eucommia seed oil microcapsules described in the above scheme, comprising the following steps:

[0037] 1) mixing gum arabic and water to obtain the first solution;

[0038] 2) mixing chitosan and acetic acid aqueous solution to obtain a second solution;

[0039] 3) mixing Eucommia ulmoides seed oil, Tween 85 and the first solution to obtain a third solution;

[0040] 4) adding the second solution dropwise to the third solution to obtain a fourth solution; the dropping speed is to add 8 to 12 g of the second solution per minute;

[0041] 5) After adjusting the pH of the fourth solution to 4.1-4.3, let stand at 4-6° C. for 25-35 minutes to obtain a gel;

[0042] 6) Adjust the pH of the gel to 6.3-6.8 to obtain a weak acid gel, mix the weak acid gel with an aqueous solution of transglutaminase, and let it stand at 28-32° C. for 0.8-1.2 hours, solid-liquid Separation and collection of precipitates;

[0066] 5. Coagulation: Add dilute hydrochloric acid to the fourth solution to adjust the coagulation pH to 4.2; put it in an ice-wat...

Embodiment 2

[0129] The yield and encapsulation efficiency of Eucommia ulmoides seed oil microcapsules obtained in Example 1 and Comparative Examples 1-17 were determined.

[0130] 1,

[0131] 2. Encapsulation efficiency: full scan to find the maximum wavelength of eucommia seed oil, establish a standard curve of eucommia seed oil at this wavelength, surface oil: take 0.5g microcapsules, add 5mL n-hexane to dissolve, centrifuge at 7000rpm for 5min, and take the supernatant The absorbance of the solution at the lower side of the maximum wavelength was brought into the standard curve to calculate the concentration. Total oil: Take 0.5g of microcapsules, add 5mL of n-hexane to dissolve, fully dissolve in a shaker for 12h, then sonicate for 1h, centrifuge at 7000rpm for 20min, take the absorbance of the supernatant at the lower side of the maximum wavelength, and bring it into the standard curve to calculate the concentration.

Abstract

The invention provides an eucommia seed oil microcapsule, an eucommia seed oil whitening essence and a preparation method and application thereof, and belongs to the technical field of cosmetics. The core material of the eucommia seed oil microcapsule comprises eucommia seed oil; the wall material of the eucommia seed oil microcapsule comprises Arabic gum and chitosan. The eucommia seed oil is encapsulated by adopting the Arabic gum and the chitosan as wall materials, so that oxidative rancidity of the eucommia seed oil can be delayed, the stability of the eucommia seed oil is improved, and the applicability of the eucommia seed oil is improved. In addition, the eucommia seed oil microcapsule can be applied to preparation of cosmetics, and the bearing rate of a water agent formula is increased. In addition, compared with the eucommia seed oil, the eucommia seed oil microcapsule disclosed by the invention has the advantages that the oxidation resistance and the whitening performance are improved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to eucommia seed oil microcapsules, eucommia seed oil whitening essence, a preparation method and application. Background technique [0002] Eucommia ulmoides seed oil is rich in unsaturated fatty acids, the content of oleic acid in the unsaturated fatty acids is 16%-18%, the content of linoleic acid is 11%-13%, and the content of α-linolenic acid is 61%-63%. α-linolenic acid has various physiological functions such as lowering blood pressure, reducing blood fat and platelet coagulation, anti-tumor and enhancing human immunity, promoting the development of nervous system, brain and retina, and delaying aging. However, polyunsaturated fatty acids such as α-linolenic acid are sensitive to light, heat and oxidizing agents, and are easily damaged by oxidation, resulting in oxidative rancidity of Eucommia seed oil. Contents of the invention [0003] The object of the present inventi...
