Embodiment 1

[0035] Dissolve chitosan oligosaccharides with a molecular weight of 2000 in 0.05 mg / mL water-soluble Vc solution to prepare a 10 mg / mL chitosan solution, and prepare a 52 mmol / L solution with a molecular weight of 20 kDa seaweed polysaccharide , in the preparation process of Panax notoginseng face cream, add 3wt% chitosan oligosaccharide solution (accounting in chitosan, the same in the following examples), 0.15wt% seaweed polysaccharide solution (accounting in seaweed polysaccharide, following examples Same), 1wt% Panax notoginseng extract, then prepare into Panax notoginseng face cream.

[0036]The preparation method of Radix Notoginseng extract in the present embodiment comprises the steps:

[0037] (1) Put Panax notoginseng in a refrigerator at -20°C, let it stand for 20 hours, pulverize it with a pulverizer, pass through a 80-mesh sieve, and obtain Panax notoginseng powder;

[0038] (2) Mix notoginseng powder with 70% ethanol in a mass ratio of 1:8, adjust the pH to 4, ...

Embodiment 2

[0041] Dissolve chitosan oligosaccharides with a molecular weight of 3000 in 0.05 mg / mL water-soluble Vc solution to prepare a 10 mg / mL chitosan oligosaccharide solution, and prepare a 50 mmol / L solution with a molecular weight of 35 kDa seaweed polysaccharide , adding 3wt‰ chitosan oligosaccharide solution, 0.15wt% seaweed polysaccharide solution and 1wt% notoginseng extract in the preparation process of notoginseng face cream, and then prepared into notoginseng face cream.

[0042] The preparation method of the Panax notoginseng extract in this example is the same as in Example 1. The content of arbutin in the Panax notoginseng extract in this example is 7.10mg / g.

Embodiment 3

[0044] Dissolve chitosan oligosaccharides with a molecular weight of 3000 in 0.05 mg / mL water-soluble Vc solution to prepare a 10 mg / mL chitosan oligosaccharide solution, and prepare a 50 mmol / L solution with a molecular weight of 35 kDa seaweed polysaccharide , adding 6wt‰ chitosan oligosaccharide solution, 0.05wt% seaweed polysaccharide solution and 0.5wt% notoginseng extract in the preparation process of notoginseng face cream, and then prepared into notoginseng face cream.

[0045] The preparation method of the Panax notoginseng extract in this example is the same as in Example 1. The content of arbutin in the Panax notoginseng extract in this example is 7.21mg / g.

Abstract

The invention discloses a method for improving the whitening effect of radix notoginseng face cream, and belongs to the technical field of cosmetics. According to the method, chitosan oligosaccharide, algal polysaccharide and a radix notoginseng extract are added into the radix notoginseng face cream, the dosage of the chitosan oligosaccharide in the radix notoginseng face cream is 0.3-0.8% by weight, thedosage of the algal polysaccharide in the radix notoginseng face cream is 0.05-0.2% by weight, and the dosage of the radix notoginseng extract in the radix notoginseng face cream is 0.5-2wt%. The radix notoginseng face cream disclosed by the invention can effectively promote skin microcirculation, is beneficial to absorption of active ingredients of radix notoginseng, deeply whitens and removes freckles, can effectively fade and remove various stubborn color spots, and inhibits generation of new pigments; meanwhile, the mask is rich in various polysaccharides, proteins and other nutrient substances, effectively nourishes the skin and enables the skin color to be uniform and shiny.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a method for improving the whitening effect of notoginseng face cream. Background technique [0002] Melanin is the main cause of human skin pigmentation. The molecular mechanism of most whitening ingredients is to improve skin color by reducing the production of melanin. Among them, inhibiting tyrosinase activity is one of the main strategies to reduce melanin production. However, long-term use of some traditional and effective whitening raw materials that inhibit tyrosinase activity, such as kojic acid and hydroquinone, can cause side effects such as skin sensitivity and canceration. [0003] Panax notoginseng, also known as Tianqi, is an Umbelliferae Araliaceae plant, mainly distributed in Yunnan, Guangxi, Jiangxi, Sichuan and other places. The Chinese herbal medicine with the same name, Panax notoginseng uses the root of the plant as a medicinal part, which has the effects...
