[0040]The preparation method of the weeding grass powder is as follows: the dried weeding grass is pulverized and passed through a 100-mesh sieve to obtain the weeding weed powder.

[0041] 2,6-Dimethyl-β-cyclodextrin, CAS number: 128446-36-6, purity: 98%, purchased from Shanghai Yuanye Biotechnology Co., Ltd.

[0042] Bifidobacterium pseudocatenulatum, Latin name: Bifidobacterium pseudocatenulatum, strain number: ATCC27919, purchased from Beijing Biobowell Biotechnology Co., Ltd.

[0043] PEG40-hydrogenated castor oil, CAS number: 61788-85-0, HLB value: 13, pH value: 6.0, purchased from Haian Petrochemical Plant, Jiangsu Province.

[0044] Polyquaternium-51, CAS No.: 125275-25-4, content: 99%, purchased from Yunnan Lilian Biological Co., Ltd.

Embodiment 1

[0046] A whitening cosmetic, consisting of the following raw materials: 12.6wt% sage extract, 0.2wt% carboxymethyl cellulose, 8wt% butanediol, 0.1wt% sodium hydroxide, 3wt% 1,2-pentanediol , 0.8wt% PEG40-hydrogenated castor oil, 0.5wt% phenoxyethanol, 3.8wt% polyquaternium-51, and the balance is deionized water.

[0047] Described weeping grass extract is prepared by the following method:

[0048] Mix the weeping grass powder and deionized water in a mass ratio of 2:7, and adjust the pH to 6.5 to obtain a slurry, then add 0.05% of the slurry weight of Bifidobacterium pseudochain and mix evenly and place it in a biochemical incubator, 35 After fermentation at ℃ for 24 hours, centrifuge at 8000rpm for 20 minutes to collect the supernatant X1 and the bottom sediment Y1; the supernatant X1 was concentrated and freeze-dried to obtain the Herba chinensis extract.

Embodiment 2

[0050] A whitening cosmetic, consisting of the following raw materials: 12.6wt% sage extract, 0.2wt% carboxymethyl cellulose, 8wt% butanediol, 0.1wt% sodium hydroxide, 3wt% 1,2-pentanediol , 0.8wt% PEG40-hydrogenated castor oil, 0.5wt% phenoxyethanol, 3.8wt% polyquaternium-51, and the balance is deionized water.

[0051] Described weeping grass extract is prepared by the following method:

[0052] (1) Mix the weeping grass powder and deionized water in a mass ratio of 2:7, and adjust the pH to 6.5 to obtain a slurry, then add pseudochain bifidobacteria with a weight of 0.05% of the slurry, mix evenly, and place in a biochemical incubator Inside, ferment at 35°C for 24 hours, centrifuge at 8000rpm for 20 minutes after the end, collect the supernatant X1 and the bottom sediment Y1;

[0053] (2) The bottom precipitate Y1 is added to an aqueous ethanol solution with a mass fraction of 80 wt%, and the mass ratio of the bottom precipitate Y1 to an aqueous ethanol solution with a ma...

Abstract

The invention discloses a plant whitening extract and application thereof to whitening cosmetics. The plant whitening extract provided by the invention is extracted from natural medicinal plants, in addition, the extraction process is green and safe, and the obtained extract can inhibit the formation of skin melanin from a plurality of ways and achieve the skin whitening effect; and meanwhile, the plant whitening extract also has the effects of moisturizing, nourishing, bacterium inhibition, sun screening and the like. The plant whitening extract also has good skin whitening and brightening effects when being used in whitening cosmetics.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a plant whitening extract and its application in whitening cosmetics. Background technique [0002] With the improvement of people's living standards, accelerated pace of life, and irregular work and rest time, skin aging has become a top priority for people, and the external manifestations of skin aging are mainly the formation of wrinkles and pigmentation. The proportion of products is also increasing. [0003] Melanin is a kind of complex and irregular very stable macromolecular compound composed of phenolic and / or indole substances through multi-step oxidation polymerization and firmly combined with proteins and polysaccharides. Melanin is the main cause of human skin pigmentation. It is mainly formed by melanocytes in the basal layer of the epidermis, and then transferred to the basal cells. With the migration of epidermal cells, it is brought to the whole layer of the ep...
