Problems solved by technology

[0006] However, since liposomes are unstable emulsification systems, there are many factors affecting their stability, among which ionic strength, HLB values ​​of other substances in the system, mixing methods, etc. may affect the stability of liposomes in the system, so it is not supported Add nano liposomes to cream system

Embodiment 1

[0023] A preparation method of resveratrol nano crystals, the preparation steps are as follows:

[0024] (1) use alcohol and stearic acid to make an alcoholic solution containing 2% stearic acid under heating and reflux, which is solution A;

[0025] (2) Gradually add resveratrol powder with a content of 98% to A, and make a saturated solution of resveratrol under reflux, which is solution B;

[0026] (3) Immediately transfer B to an ultrasonic oscillator with a power of 250W and a frequency of 33kHz, and naturally cool down while ultrasonically, during which crystallization is continuously precipitated; this process continues until the temperature is 15 degrees, and then cooled with ice water in the later stage;

[0027] (4) After the ultrasound is finished, carry out suction filtration, and wash the filter cake with 1 times the amount of pure water of A; when the suction filtration starts, there is a large amount of material leakage, and after the filter cake is formed and c...

Embodiment 2

[0030] A preparation method of resveratrol nano crystals, the preparation steps are as follows:

[0031] (1) make the alcoholic solution containing stearic acid 7% under heating reflux with alcohol and stearic acid, be solution A;

[0032] (2) Gradually add resveratrol powder with a content of 98% to A, and make a saturated solution of resveratrol under reflux, which is solution B;

[0033] (3) Immediately transfer B to an ultrasonic oscillator with a power of 250W and a frequency of 33kHz, and cool down naturally while ultrasonically, during which crystallization is constantly precipitated; this process continues until the temperature is 25 degrees, and then cooled with ice water in the later stage;

[0034] (4) After the ultrasonic wave is finished, perform suction filtration, and wash the filter cake with 2 times the amount of pure water of A; when the suction filtration starts, there is a large amount of material leakage, and after the filter cake is formed and compacted, ...

Embodiment 3

[0037] A preparation method of resveratrol nano crystals, the preparation steps are as follows:

[0038] (1) use alcohol and stearic acid to make an alcoholic solution containing 5% stearic acid under reflux, which is solution A;

[0039] (2) Gradually add resveratrol powder with a content of 98% to A, and make a saturated solution of resveratrol under reflux, which is solution B;

[0040] (3) Immediately transfer B to an ultrasonic oscillator with a power of 250W and a frequency of 33kHz, and naturally cool down while ultrasonically, during which crystallization is continuously precipitated; this process continues until the temperature is 20 degrees, and then cooled with ice water in the later stage;

[0041] (4) After the ultrasound finishes, perform suction filtration, and wash the filter cake with pure water of 1.5 times the amount of A; when the suction filtration begins, there is a large amount of material leakage, and after the filter cake is formed and compacted, there...

Abstract

The invention relates to the beauty skin-care cosmetic technical field, specifically relates to a method for preparing white chenopodium album alcohol nanometer crystal and application, wherein the water-solubility of white chenopodium album alcohol is bad, biological utility is low and seriously influences wide application in each field. Therefore, the invention provides a method for preparing white chenopodium album alcohol nanometer crystal which is provided with better stability, higher utility and water-solubility, which not only results in effective component of extract dissolve completely, saves raw material greatly, but also is provided with little extract usage, fast adsorption, high utility, good action effect, little side effect and convenient to use. The invention provides white chenopodium album alcohol nanometer crystal that completely overcomes the insufficiency of the prior nanometer cosmetics, which has a plurality of advantages in the cosmetics when using.

Description

technical field [0001] The invention relates to the technical field of beauty and skin care cosmetics, in particular to a preparation method and application of resveratrol nanocrystals. Background technique [0002] Resveratrol is the main raw material in medicine, chemical industry, food and cosmetics. It has been found to have a variety of pharmacological activities, including antioxidant activity, antiplatelet aggregation, antiatherosclerosis, anti-inflammatory, estrogen-like activity, growth inhibitory activity, immunomodulatory and chemopreventive effects. [0003] Application of resveratrol in cosmetics The molecular structure of resveratrol has the characteristics of capturing free radicals, anti-oxidation, and absorbing ultraviolet light. It has excellent efficacy in cosmetics and is a good natural antioxidant. Generally speaking, antioxidants used in cosmetics mainly play the role of skin antioxidant, so that the skin can delay aging. In addition, resveratrol can ...
