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.)

The invention discloses novel anthocyanin lipidosome lyophilized powder. The novel anthocyanin lipidosome lyophilized powder is prepared from mannosylerythritol lipid or a mannosylerythritol lipid / phospholipid mixture as a wall material. A specific preparation method comprises following steps: (1), mannosylerythritol lipid is dissolved in an organic solvent, and a solution A is obtained; (2), anthocyanin is dissolved in a solvent, and a solution B is obtained; (3), the solution A obtained in the step (1) and the solution B obtained in the step (2) are mixed uniformly, subjected to ultrasonic treatment and left to stand for balance, a mixture is put in a rotary evaporator and subjected to reduced-pressure evaporation, and a lipid membrane is obtained; (4), a phosphate buffer solution is added to the lipid membrane obtained in the step (3), membrane filtration is performed after stirring and dissolving, and a lipidosome suspension is obtained; (5), a lyophilized protective agent is added to the lipidosome suspension obtained in the step (4), and the novel anthocyanin lipidosome lyophilized powder is obtained through lyophilization. The prepared anthocyanin lipidosome is good in stability; the preparation method is simple and low in cost; the preparation wall material of the lipidosome is enriched, and the novel anthocyanin lipidosome lyophilized powder can be applied to the fields of food and cosmetics.

The present invention relates to a cosmetic composition using a mannosylerythritol lipid, which is a kind of glycolipid, as a stabilizer in order to prevent kojyl methylenedioxycinnamate, which is an active ingredient having various skin effects such as antiaging, whitening and antioxidation, from causing crystallization inside a dosage form. Even if the cosmetic composition according to the present invention contains a high concentration of an active ingredient, crystal precipitation does not occur in various dosage forms, and thus the functionality of the active ingredient is maximized, skin delivery is increased and the texture during use is improved.
