[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...
