Problems solved by technology

In the existing skin care products, although there are many whitening products, the basic functional ingredients are often artificially synthesized, for example, niacinamide, which is now highly regarded in the whitening industry; Synthetic-based, it is easy to introduce impurities, so it is easy to cause certain irritation to the skin; secondly, this kind of pure functional ingredients often have a single component, and multiple pure functional ingredients exist independently of each other, and it is not easy to form a good synergistic effect. Under the premise of independently exerting their effects, the effect will be unstable because the content used in skin care products is limited by various factors such as price.
[0004] Although plant extracts are used in some skin care products, the different compatibility of plants will greatly affect the efficacy of skin care products. At the same time, different extraction methods have great differences in the extraction of active ingredients in plants. , and the active ingredients in the extract will greatly affect the efficacy of skin care products

preparation example Construction

[0064] Such as figure 1 Shown, the present invention also provides a kind of preparation method according to a kind of whitening essence described above, comprising:

[0065] S100, the preparation of the mixed extract of Angelica sinensis and Radix Astragali: crush Angelica sinensis, add ethanol to it, mix and freeze, and at the same time, pass nitrogen into the freezing container to a pressure of 10-15 atmospheres, keep it for 1-2h, and then use 5- The heating rate of 6°C / h is raised to not lower than 20°C to obtain a mixed solution; adding Astragalus membranaceus to the mixed solution and grinding and extracting at 50-60°C; Under the condition of 70-90°C, reflux extraction for 2-3 times, combine the extracts; centrifuge the extracts, take the supernatant, and concentrate the supernatant to a volume of 1 / 1 of the volume of the supernatant 20-1 / 10, to get mixed extracts of angelica and astragalus;

[0066] S200. After mixing the base material at a temperature of 60-80°C unti...

Embodiment 1

[0094]The preparation of the mixed extract of angelica and astragalus (the weight ratio of angelica and astragalus is 5:1): after the angelica is broken, add 20 parts by weight of ethanol to it, mix and freeze at -10°C under normal pressure for 2h, and then Cool down to -25°C at a cooling rate of 5°C / h, and at the same time pass nitrogen gas into the freezing container at a rate of 0.3 MPa / h to pressurize to 10 atmospheres, keep it for 2 hours, and then pressurize it for 5 The heating rate of °C / h is raised to not less than 20 °C to obtain a mixed solution; adding Astragalus membranaceus to the mixed solution and placing it in an extraction device at 60 °C for grinding and extraction; the extracted mixed solution The liquid is refluxed and extracted 2-3 times at a temperature of 90°C (starting from the second extraction, each time adding 5 parts by weight of ethanol to the residue and continuing to reflux), combining the extracts; centrifuging the extracts Finally, take the su...

Embodiment 2

[0097] Prepare as in the preparation method of Example 1, the difference is that the dosage of mixed extracts of Angelica sinensis and Radix Astragali is 8 parts by weight, and the dosage of Rhodiola rosea extract and white fungus extract is 1.5 parts by weight respectively, to prepare whitening essence A2 .

Abstract

The embodiment of the invention discloses a whitening essence and a preparation method thereof. The whitening essence includes mixed extracts of angelica and astragalus, rhodiola rosea extracts, white fungus extracts and base materials; the preparation method includes: mixed extracts of angelica and astragalus Preparation; mixture of angelica and astragalus mixed extract, rhodiola rosea extract, white fungus extract and base material. The present invention uses specific plant extracts as functional components to avoid the irritation of synthetic functional components. At the same time, some specific plants are mixed and extracted to further improve the extraction method. With the help of the synergistic effect of the plant's own components, it is more effective. Maximize the whitening performance and improve the stability of its overall efficacy.

Description

technical field [0001] The embodiments of the present invention relate to the field of preparation of essence, in particular to a whitening essence and a preparation method thereof. Background technique [0002] Essence, as a kind of facial skin care product, usually repairs and improves the skin through a higher content and more types of functional ingredients. [0003] There is such a record in "Tao An Meng Yi" in the Ming Dynasty, "In front of the lamp and under the moon, people have no right color. The so-called 'one white can cover a hundred ugliness' is the power of powder."

Abandoning makeup methods such as applying foundation to brighten skin tone, skin care, which essentially improves skin tone, is more popular among most people. acceptance. In the existing skin care products, although there are many whitening products, the basic fun...
