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

[0068] (Manufacturing Example 1: Manufacturing Examples of MEL-A, MEL-B, and MEL-C)

[0069] One loop of Pseudozyma antarctica NBRC 10736 (obtained from: NITE Biological Resource Center) flora was inoculated into a seed medium (20 ml / 500 ml shaker flask) to carry out 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 recovered. Add 50m...

[0071] (Manufacturing Example 2: Manufacturing Example of Inverted MEL-B)

[0072]Inoculate 0.2ml of Pseudozyma tsukubaensis (シユ一ドザイマッックバアンシス) frozen stock into 20ml of YM medium (1W / V% glucose, 0.3W / V% yeast extract, 0.5W / V% polypeptone, 0.3 W / V% malt extract, pH 5.6) / 500 ml volume shaking flask, cultured overnight at 26° C., 180 rpm, and used 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...

manufacture Embodiment 3

[0074] (Manufacturing Example 3: Manufacturing Example of MEL-C)

[0075] 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

Disclosed are: a pigment for cosmetic preparations, which is safe for use on the human body and has good adhesion to the skin and excellent feeling of use; a method for producing the pigment for cosmetic preparations; and a cosmetic preparation which is capable of obtaining moist and fresh feeling of use by containing the pigment for cosmetic preparations. Specifically disclosed is a pigment for cosmetic preparations, which is obtained by coating the surface of a pigment with a mannosylerythritol lipid that is a glycolipid represented by general formula (1) and configured of mannose, a sugar alcohol and a fatty acid. (In the formula, R1 and R2 may be the same or different and each represents an aliphatic acyl group having 6-20 carbon atoms; R3 and R4 may be the same or different and each represents a hydrogen atom or an acetyl group; and n represents an integer of 2-4.)

Description

technical field [0001] The present invention relates to a cosmetic pigment preferably blended in makeup cosmetics such as foundations, eye shadows, and lipsticks, sunscreen cosmetics, or basic cosmetics such as emulsions and creams, a method for producing the same, and cosmetics containing the same. Background technique [0002] Traditionally, it has been used as a pigment in foundation cosmetics such as foundation, eye shadow, and blush, sunscreen cosmetics, emulsions, creams, and other basic cosmetics to improve water resistance to prevent smudges, or to improve the texture of pigments, etc. A pigment made by coating the surface of a pigment with various compounds. [0003] Here, as means for improving water resistance, a method of coating the surface of a pigment with a silicone compound or a fluorine compound is known (see Patent Documents 1 and 2). Cosmetic pigments obtained by coating the surface of the pigment with a silicone compound or a fluorine compound can impar...
