Problems solved by technology

[0006] The ultraviolet absorbers used in existing sunscreen products, such as p-aminobenzoic acid derivatives, cinnamate derivatives, salicylic acid derivatives, etc., are poor in safety and easy to penetrate into the skin, especially the degraded small molecules, which are easily absorbed Skin absorption, so the country strictly regulates its usage

Embodiment 1

[0044] The preparation of embodiment 1 arbutin lipid nanoemulsion

[0045] The raw materials for preparing arbutin lipid nanoemulsion are listed in Table 1. Among them, arbutin was purchased from Xi'an Rongsheng Biotechnology Co., Ltd.

[0046] Table 1

[0047]

[0048]

[0049] The preparation mode of this lipid nanoemulsion is as follows:

[0050] 1) According to the above prescription, add the first part of raw materials into the shear mixer, and shear at a high speed under the condition of 10000rpm until there is no visible solid in the system;

[0051] 3) Add the second part of raw materials to the product of step 1), and shear at a high speed under the condition of 10000rpm to obtain colostrum, which is processed by a high-pressure homogenizer at a pressure of 2000bar and circulated 10 times to obtain transparent and clear arbutin Lipid nanoemulsion.

Embodiment 2

[0052] Embodiment 2 whitening essence

[0053] The raw material ratio of this embodiment is shown in Table 2. Wherein the arbutin lipid nanoemulsion is prepared for Example 1.

[0054] Table 2

[0055]

[0056]

[0057] The preparation method of this whitening essence is as follows:

[0058] Mix and heat the components of component C to 75°C, stir for 15min at a stirring speed of 1000rpm, add component B when cooled to 50°C, stir at 500rpm for 10min, add component A after cooling to room temperature, and homogenize to obtain .

Embodiment 3

[0059] Embodiment 3 whitening essence

[0060] The raw material ratio of this embodiment is shown in Table 3. Wherein the arbutin lipid nanoemulsion is prepared for Example 1.

[0061] table 3

[0062]

[0063] The preparation method of the whitening essence is the same as in Example 2.

Abstract

The invention provides whitening essence containing bearberry extract lipid nanoemulsion. The whitening essence is prepared from a component A, a component B and a component C, wherein the component A comprises arbutin lipid nanoemulsion, antioxidant biological active peptide, vitamin C and the like; the component B is selected from glycerinum, glycerin monostearate, hexadecyl alcohol, squalane, licoflavone, vitamin E, microcrystalline wax and the like; the component C is selected from avocado oil, silicon oil, vitamin E, stearate, hexadecyl alcohol, Vaseline, beeswax, lanum and the like. The whitening essence does not contain chemical ultraviolet absorbent and is a pure natural cosmetic composition by use of plant whitening agent and biological active peptide as functional components, the bearberry extract based whitening essence can reduce the tyrosinase activity and inhibit melanosome maturity, and can be further effectively combined with licoflavone and biological active peptide, thereby achieving good whitening effect.

Description

technical field [0001] The invention belongs to the field of cosmetics, in particular to a whitening essence containing lipid nanoemulsion of bearberry extract. Background technique [0002] Under normal conditions, melanin can absorb excess sunlight, especially ultraviolet rays, and protect the body. If the generated melanin cannot be metabolized in time and accumulates and deposits in the epidermis, freckles, chloasma, age spots, etc. will appear on the skin. It is generally believed that the formation mechanism of melanin is the synthesis of tyrosine in melanocytes catalyzed by tyrosinase. The process of oxidizing tyrosine into melanin is quite complicated, and the rate-limiting step is tyrosinase. Causes the enhancement of tyrosinase and melanocyte activity, thereby promoting the formation of melanin. [0003] When the skin is directly exposed to sunlight, cosmic rays, air and physical and chemical pollutants, it will cause the skin to produce a kind of active oxygen f...
