Problems solved by technology

Cosmetic pigments obtained by coating the surface of the pigment with a silicone compound or a fluorine compound can impart water resistance, thereby being excellent in preventing smudges and improving the durability of makeup, but there is a problem that there is no powdery feeling due to the compound. Moisturizing feeling; poor adhesion to skin due to poor affinity for organisms
However, the existing biosurfactants have low hydrophobicity, so they are not suitable for cosmetic pigments
On the other hand, it is known that mannose erythritol lipid (MEL) has the effect of improving skin roughness in skin care because it easily forms a lamellar structure, but it has not been reported as a pigment for cosmetics

manufacture Embodiment 1

[0069] (Manufacturing Example 1: Manufacturing Examples of MEL-A, MEL-B, and MEL-C)

[0070] One inoculation loop of Pseudozyma antarctica NBRC 10736 (obtained from: NITE Biological Resource Center) flora was inoculated into a seed medium (20 ml / 500 ml shaking flask) to perform seed culture. Incubate overnight at 30°C. The obtained culture solution was used as an inoculum. The composition of the seed medium is: 4W / V% glucose, 0.3W / V% NaNO 3 , 0.02W / V%MgSO 4 ·7H 2 O, 0.02W / V% KH 2 PO 4 , 0.1W / V% yeast extract. For cultivation, 75 ml of the above inoculum was inoculated into 1.5 L of production medium (5 L tank), and cultured in a 5 L tank at 30° C., 300 rpm (stirring rotation), and 0.5 L / min (Air). The composition of the production medium is: 3W / V% soybean oil, 0.02W / V% MgSO 4 ·7H 2 O, 0.02W / V% KH 2 PO 4 , 0.1W / V% yeast extract. 250 ml of the culture solution was centrifuged (6500 rpm, 30 min), the supernatant was removed, and the precipitate (bacteria) was recovere...

[0072] (Manufacturing Example 2: Manufacturing Example of Inverted MEL-B)

[0073]Inoculate 0.2ml of Pseudozyma tsukubaensis (シュードザイマッックババンシス) frozen stocks into 20ml of YM medium (1W / V% glucose, 0.3W / V% yeast extract, 0.5W / V% polypeptone, 0.3W / V (V% malt extract, pH 5.6) / 500ml capacity shaking flask, cultured overnight at 26°C, 180rpm, as seed bacteria. 0.2 ml of seed bacteria were inoculated again into 20 ml of YM seed medium / 500 ml capacity shaking flask, and cultured overnight at 26° C. and 180 rpm to obtain seed bacteria. Inoculate 20 ml of inoculum into 2 L of YM medium / 5 L tank containing 15 W / V% olive oil, and cultivate for 8 days at 26° C., 300 rpm (1 / 4 VVM, 0.5 L air / min). The culture solution was centrifuged at 7,900rpm·60min·4°C, and separated into bacteria (including MEL-B) and supernatant. Add 80ml of ethyl acetate to the cell components, stir up and down to fully suspend the cells, and then perform centrifugation at 7,900rpm·30min·4°C. An equal amount of satu...

manufacture Embodiment 3

[0075] (Manufacturing Example 3: Manufacturing Example of MEL-C)

[0076] Inoculate 0.2 ml of the frozen stock of Pseudozyma hubeiensis into 20 ml of YM seed medium / 500 ml of shaking flask, and cultivate it overnight at 26° C.·180 rpm to serve as seed bacteria. 0.2 ml of seed bacteria was re-inoculated into 20 ml of YM seed medium / 500 ml capacity shaker flask, and cultured overnight at 26° C.·180 rpm to serve as seed bacteria. Inoculate 20ml of inoculum into 2L of YM medium / 5L·tank and culture at 26°C·300rpm (1 / 4VVM, 0.5L·air / min) for 8 days. The culture solution was centrifuged at 7,900rpm·60min·4°C, and separated into bacteria (including MEL-C) and supernatant. Add 80ml of ethyl acetate to the cell components, stir up and down to fully suspend the cells, and then perform centrifugation at 7,900rpm·30min·4°C. An equal amount of saturated brine was added to the obtained supernatant, followed by stirring to obtain an ethyl acetate layer. An appropriate amount of anhydrous so...

Abstract

To provide cosmetic pigments that are human-body friendly with good skin adhesion and that provide good feeling, their production method, and cosmetics containing such cosmetic pigments which provide fresh and enriched feeling accordingly. Pigment surfaces are coated with mannosylerythritol lipid, which is glucolipids, consisting of mannose, sugar alcohol and a fatty acid as shown in the general expression(1) below: (Note: In the general expression, R 1 and R 2 denote aliphatic acyl group with carbon numbers 6 through 20, which can be either same or different. R 3 and R 4 denote hydrogen or acetyl group, which can be either same or different. n denotes an integer in the range of 2 to 4.)
