Description

Composition for skin care comprising flocurin

To a composition for skin care.

Flocculin is a lectin-like protein in the Lager yeast cell wall, which serves to precipitate lager yeast. In particular, it has a strong binding property with mannose, binds with mannose of other yeast walls, produces precipitates of yeast cells, and also has a function of protecting yeast from stress factors such as nutrient depletion, temperature and UV in the culture.

On the other hand, yeast is used as a cosmetic ingredient for the purpose of skin improvement such as wrinkle improvement and whitening effect. The yeast extract is used as a cosmetic ingredient by removing yeast cells from the cell wall by proteolytic enzymes, organic solvents or autolysis, and then removing the insoluble portions and concentrating them. The thus-treated yeast extract is composed of a complex of various proteins, peptides, amino acids, minerals and vitamin B groups and is useful as a cosmetic additive. Other yeast extracts are known in skin wound healing and collagen synthesis effects (US Patent 5,776,441, US Patent 6,177,105) and are used as cosmetic raw materials. However, to date, there has been no use of flocurin in cosmetic compositions for skin care purposes.

For induction of melanogenesis, 0.1 μM α-MSH was added, and then added for each sample, followed by culturing for 3 days. As a positive control for melanin production, arbutin was treated at 100 ppm. The cultured cells were washed with PBS and trypsin. The recovered cells were counted with a hematocytometer and collected at 1 × 10 ⁶ cells / mL for each treatment group, and centrifuged at 1000 rpm for 10 minutes to obtain cells. The recovered cells were dried at 60 ° C for 1 hour, and 100 μl of a 1 M NaOH solution containing 10% DMSO was added to obtain melanin in the cells. This melanin solution was assayed for absorbance at 490 nm with a microplate reader to evaluate the inhibition of melanin formation.
