  By the way, it is known that the performance of the obtained powder is greatly influenced by the type of coating and the conditions of modification with respect to the surface treatment, and the feel, texture, etc. obtained are affected by the coating conditions (manufacturing conditions). There was a problem that the characteristics of the treated powder were difficult to control stably. In general, high molecular weight compounds have been confirmed to form a dense network structure film or a porous structure film. However, when surface treatment is performed by this film forming ability, bonding between powders is not possible. As a result, there is a problem in that it tends to become hard and, as a result, hard agglomeration that is difficult to grind easily occurs, and when blended with cosmetics, the feeling is remarkably impaired.

  Further, according to the study by the present inventors, even when the coating is a suizendinori-derived sugar derivative, after dissolving the suizendinori-derived sugar derivative in water and uniformly dispersing the powder in this solution, It has been found that the method of heating and drying / pulverizing produces a hard agglomerate that exhibits a remarkable film forming effect and is difficult to grind.

  The present invention has been made in view of the above-described problems, and is based on the genus A. sacrum belonging to the genus Aphanothece of the family Chrooccaceae of the Cyanophyceae. ), And a method for producing the same, which is excellent in moisture retention, adhesion, antiviral activity, and antioxidant activity, and a method for producing the same. By blending, the object is to provide a cosmetic having an excellent moisturizing effect, feel, adhesion / affinity to the skin, uniformity of the cosmetic film, and an effect of improving makeup.

  As a result of intensive studies to achieve the above-mentioned object, the present inventors made a slurry in which a powder is uniformly dispersed in a suizendinori-derived sugar derivative solution into a viscous slurry and then freeze-dried and pulverized or sprayed. It has been found that by drying, a treated powder having a weak cohesive force and excellent in touch can be obtained. And when this treated powder was blended into cosmetics, it was found that cosmetics excellent in feel, skin adhesion / affinity, moisturizing effect, uniformity of makeup film, and improvement effect of makeup retention were obtained. .

In short, the suizendinori-derived sugar derivative-coated powder according to the first invention is:
A sugar structure having a hexose structure and a sugar structure having a pentose structure derived from the freshwater cyanobacteria Suizendinori and having a hexose structure on the powder surface is an α-glycoside bond or a β-glycoside. The sugar chain unit includes a sulfated sugar having a repeating bond of a sugar chain unit linked in a straight chain or a branched chain by a bond, wherein the sugar chain unit is lactated as a sugar structure. It is characterized in that 2.7 or more hydroxyl groups per group are sulfated, or a sugar derivative containing 1.5% by mass or more of sulfur element in all elements is coated.

Next, a method for producing a suizendinori-derived sugar derivative-coated powder according to the second invention,
After mixing the slurry in which the powder and the suizendinori-derived sugar derivative are dispersed to form a viscous slurry, the viscous slurry is freeze-dried and pulverized or spray-dried so that the suizendinori-derived sugar derivative is It is characterized in that it is directly coated.

The cosmetic according to the third invention is
It is characterized in that it is formed by blending a suizendinori-derived sugar derivative-coated powder according to the first invention.

When the viscous slurry obtained by dispersing the powder and the sugar derivative derived from Suizendinori is simply heated and dried, an agglomerate having a high density is formed and it is difficult to grind. On the other hand, in the present invention, the viscous slurry is freeze-dried or spray-dried.
When the viscous slurry is freeze-dried, an agglomerate having a low density is formed and can be easily pulverized, so that a treated powder with excellent feel can be obtained. In addition, when the viscous slurry is spray-dried, the viscous slurry is sprayed in a device set to an appropriate drying temperature and dried in a sprayed state. Can be obtained.

Examples of a method for coating the surface of the powder with a suizendinori-derived sugar derivative include the following.
First, using a disperser such as a homogenizer, the sugar derivative derived from suizendinori is dissolved in the solution. Next, using a stirrer, the sugar derivative-derived sugar derivative solution and the powder are uniformly stirred. The viscous solution is freeze-dried and pulverized with an impact pulverizer (hammer mill), and then sized using an automatic sieving machine, or spray-dried while stirring the heated viscous slurry. After feeding into the machine tank, spray drying, and sizing using an automatic sieving machine or the like, the desired suizendinori-derived sugar derivative-coated powder is obtained.

Here, the concentration of the sugar derivative derived from suizendinori that dissolves in water is preferably 0.5% by mass or less based on the mass of water. When the concentration exceeds 0.5% by mass, the viscosity of the viscous slurry becomes extremely high and handling is difficult.
The amount of water in which the powder is dispersed depends on the amount of water absorbed by the powder, but is preferably a concentration that does not cause sedimentation in the viscous slurry when freeze-dried. It is preferable that it is less than 50-300 mass%. If the amount is less than 50% by mass, the viscosity of the viscous slurry becomes remarkably high, so that uniform dispersion may be difficult. If the amount exceeds 300% by mass, powder sedimentation occurs and a uniform treated powder cannot be obtained.
In addition, the amount of water in the case of spray drying is preferably an amount that provides a viscosity that can be fed into the spray dryer tank without being clogged, and specifically ranges from 500% by mass to 1000% by mass. . If the amount is less than 500% by mass, the spray dryer tank may be clogged. If the amount exceeds 1000% by mass, the total amount increases and handling of the viscous slurry becomes difficult.
The surface treatment amount of the sugar derivative derived from Suizendinori is 0.0001 to 0.5% by mass with respect to the mass of the powder, although it depends on the particle diameter and specific surface area of the surface-treated powder. It is preferable that it exists in the range. If the amount is less than 0.0001% by mass, the effects of the present invention may not be achieved. If the amount exceeds 0.5% by mass, aggregation may be too strong and the feel may be deteriorated, and handling in the manufacturing process may be difficult. It is not preferable. A more preferable range of the surface treatment amount is 0.0001 to 0.1% by mass.

  In the present invention, various kinds of surface treatments such as conventionally known surface treatments may be further performed on the powder coated with the suzenzinori-derived sugar derivative. Examples of this surface treatment include fluorine compound treatment (perfluoroalkyl phosphate treatment, perfluoroalkylsilane treatment, perfluoropolyether treatment, fluorosilicone treatment, fluorinated silicone resin treatment, etc.), silicone treatment (methyl hydrogen). Polysiloxane treatment, dimethylpolysiloxane treatment, vapor phase tetramethyltetrahydrogencyclotetrasiloxane treatment, etc.) Silicone resin treatment (trimethylsiloxysilicic acid treatment, etc.), pendant treatment (addition of alkyl chain etc. after vapor phase silicone treatment) Silane coupling agent treatment, titanium coupling agent treatment, aluminum coupling treatment, silane treatment (alkylated silane, alkylated silazane treatment, etc.), oil agent treatment, N-acylated lysine treatment, polyacrylic treatment Acid treatment, metal soap treatment (a stearate salt or myristate treatment, etc.), acrylic resin treatment, an inorganic compound treatment, plasma treatment, mechanochemical treatment. A plurality of these processes can be used in combination.
