Example Embodiment

[0040]The preparation method of the panpo powder is as follows: The dried grate is pulverized, and the mesh powder is obtained.

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

[0042] Fake Chain Bacteria, Latin Name: Bifidobacterium Pseudocateenulatum, strain number: ATCC27919, purchased in Beijing Baio Bowei Biotechnology Co., Ltd.

[0043] PEG40-hydrogenated castor oil, CAS: 61788-85-0, HLB value: 13, pH: 6.0, purchased in Hai'an Petrochemical Plant, Jiangsu Province.

[0044] Poly quaternary ammonium salt-51, CAS: 125275-25-4, content: 99%, purchased in Yunnan Lily Biological Co., Ltd.

Example Embodiment

[0045] Example 1

[0046] A whitening cosmetic, consisting of 12.6 wt% gauze, 0.2 wt% carboxymethylcellulose, 8 wt% butanediol, 0.1 wt% sodium hydroxide, 3 wt% 1,2-pentanediol 0.8 wt% PEG40-hydrogenated castor oil, 0.5 wt% phenoxy ethanol, 3.8 wt% poly quarantine-51, margin is deionized water.

[0047] The gobbial grass extract is prepared from the following method:

[0048] The gauge powder and deionized water are mixed by mass ratio 2: 7, and the pH is adjusted to 6.5 to give a slurry, then the slurry weight of 0.05% of the fake bifurcus is mixed, and then placed in the biochemical incubator, 35 At ° C fermented 24 h, then centrifuge at 8000 rpm at a rotational speed of 8000 rpm, the upper tank X1 and the bottom precipitate Y1; the supernatant X1 was concentrated, and dried to give a spurbladed grass extract.

Example Embodiment

[0049] Example 2

[0050] A whitening cosmetic, consisting of 12.6 wt% gauze, 0.2 wt% carboxymethylcellulose, 8 wt% butanediol, 0.1 wt% sodium hydroxide, 3 wt% 1,2-pentanediol 0.8 wt% PEG40-hydrogenated castor oil, 0.5 wt% phenoxy ethanol, 3.8 wt% poly quarantine-51, margin is deionized water.

[0051] The gobbial grass extract is prepared from the following method:

[0052] (1) Mix the panched powder and deionized water in mass ratio of 2: 7, and adjust the pH to 6.5 to give a slurry, then add a slurry weight of 0.05%, a fake bispiobacteria mixed and uniformly placed in a biochemical incubator. Inside, 35 ° C fermentation 24 h, after the end of 8000 rpm was centrifuged for 20 min, and the upper cleaner X1 and the bottom precipitation Y1 were collected.

[0053] (2) The bottom precipitate Y1 is added to a water solution of 80% by weight of the mass fraction, and the mass ratio of the bottom precipitate Y1 and the mass fraction of 80% by weight is 1: 8, then the ultrasound extracti...

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...
