Liquorice extract skin care product composition and preparation method thereof

Abstract

The invention belongs to the technical field of skin care products, and particularly relates to a licorice extract skin care product composition and a preparation method thereof. The invention aims to provide the cosmetic which is strong in stability, natural, safe, hypoallergenic and capable of anti-inflammation, relieving and repairing. The composition comprises 1.5-6 wt% of a licorice extract, 0.1-1 wt% of a pepper kava extract, 1-3 wt% of a soybean milk fermentation product, and 0.5-1.5 wt% of a bifidus yeast fermentation product lysate. The licorice extract, the pepper kava extract and the bifidus yeast fermentation product lysate adopted by the invention can effectively promote proliferation and metabolism of human epidermis cells, also have a good anti-inflammatory effect, help problem skin to grow and inhibit inflammation, and enable the skin to recover a normal state, the licorice extract, the Kava pepper extract and the bifidus yeast fermentation product lysate can also effectively resist skin oxidation and slow down skin aging, and the bean fermentation product contained in the skin care product can control the skin micro-ecology by inhibiting the growth of harmful bacteria and promoting the reproduction of beneficial bacteria.

Description

technical field

[0001] The invention relates to the technical field of skin care products, in particular to a licorice extract skin care product composition and a preparation method thereof. Background technique

[0002] Cosmetics are used for the preparation of the human body (except soap) for the purpose of beautifying, preserving or changing the appearance of a person (for example, for performance), or for cleansing, coloring, abrading, correcting or protecting the skin, hair, nails, eyes or teeth adjust.

[0003] As the external living environment of human beings is polluted and destroyed more and more seriously, the possibility of toxic and harmful pollutants, such as PM2.5, causing damage to the skin and epidermis is gradually increasing. In addition, long-term use of artificially synthesized chemicals and minimally invasive beauty treatments has also aggravated the damage to the skin barrier. Therefore, beauty lovers all need skin care products or cosmetics that can...

Examples

Embodiment

[0022]

[0023] The remaining components of each example are polyhydric alcohols and nonionic surfactants.

[0024] The bean fermented product that each embodiment all adopts is black bean fermented product.

[0025] Each example was prepared by the following steps:

[0026] S1. Weighing licorice extract, kava pepper extract, soybean milk fermentation product and bifid yeast fermentation product lysate, and blending each raw material;

[0027] S2. adding the blended raw material obtained in step 1 into the water-soluble auxiliary material, and shearing to obtain a turbid liquid;

[0028] S3. The turbid liquid obtained in step 2 is made into an emulsion by using micro-fluidic technology to obtain a licorice extract skin care composition.

experiment example 1

[0030] Carry out anti-inflammatory test to the skin care composition of embodiment 1-4, specifically adopt mouse ear swelling experiment to test, the skin care composition prepared in each embodiment is applied to the red and swollen place of mouse ear, according to 100mg / The application amount of kg was applied, and the swelling inhibition rate was recorded in the table below.

[0031] group Example 1 Example 2 Example 3 Example 4 swelling inhibition rate 42.5％ 53.1％ 47.2％ 61.3％

experiment example 2

[0033] The antioxidation performance of the skin care composition of embodiment 1-4 is detected, specifically adopt the scavenging rate of DPPH / methanol solution to measure the antioxidation performance of each embodiment,

[0034] Prepare 0.2mmol / L DPPH / methanol solution; prepare different concentrations of sample solutions to be tested; pipette 2mL sample solution and 2mL DPPH / solution into stoppered test tubes, mix well, react in the dark for 30min, and measure the absorbance value at 517nm wavelength A 1 ; Take 2mL of sample solution and 2ml of methanol respectively into a stoppered test tube, mix well, and react in the dark for 30 minutes, and measure the absorbance value A at a wavelength of 517m 2 ; Take 2mL of DPPH solution and 2mL of methanol respectively into a stoppered test tube, mix well, and react in the dark for 30 minutes, and measure the absorbance value A at a wavelength of 517nm o ; Among them, the calculation formula of DPPH clearance rate is
