No. 49529. According to this method, a monolithic capsule in which the enzyme is dispersed in wax particles is obtained. In the case of the monolith type, only the enzyme that comes out in the section where the capsule has collapsed will work, so the efficiency of the enzyme will be low. According to the present invention, a powdery enzyme is dispersed in a liquid or a water-soluble solid that does not affect the enzyme activity, and is encapsulated with wax, whereby a reserve-type capsule having a wax film can be obtained. In the reserve type capsule, the inclusions are released by the collapse of the membrane,
Enzymes contained therein can work efficiently and reliably.

ので、任意に調製が可能である。According to a preferred embodiment of the present invention, a film material in a molten state is floated on a liquid having a higher specific gravity and not compatible with the film material. The core material is cooled to a temperature lower than the melting point of the film material, and the core substance is dropped therein. While the core material passes through the melted layer of film material, the film material adheres around the core material, and then moves to a layer of liquid in which the film material does not dissolve and is cooled to cure the film material. To complete the encapsulation. It is preferable to cool the core material below the melting point of the film material because the film material immediately adheres and hardens around the core material while the core material passes through the layer of the film material in the molten state. Since the size of the capsule is determined by the size of the droplet or solid to be dropped, it can be arbitrarily prepared.

The lower part is cooled below the melting point of paraffin (membrane material) (5 ° C), and the vicinity of the gas-liquid interface is above the melting point of paraffin (melting point + 10
(~ 20 ° C) to keep the paraffin in a molten state
(Specific gravity about 0.78). Then, float the paraffin on the water in a molten state (less than 1 mm thick). Then, polyethylene glycol (average molecular weight: 400) (core substance: specific gravity: 1.13) cooled below the melting point of paraffin (about 7 ° C) is added dropwise. The size of the capsule can be changed by arbitrarily changing the size of the polyethylene glycol to be dropped. The paraffin (membrane material) surrounds the polyethylene glycol (core material) while the polyethylene glycol falls down the paraffin (membrane material) phase due to the difference in specific gravity.
Is formed, and moves to a water phase due to a difference in specific gravity, and is cooled by water and hardened. The cured capsules are taken out of the container (curing tank) by a belt conveyor and collected. The resulting capsule is covered with a very thin film of paraffin and collapses under light load. Also, since it is made of paraffin, it has excellent moisture barrier properties and is harmless to humans.

る。Example 2 FIG. 2 shows a method for producing an enzyme-containing capsule of the present invention. Container (300ml measuring cylinder)
Approximately 200 ml of water (a liquid in which the film material is insoluble; specific gravity 1.00) is added to the mixture, and the lower part is cooled to below the melting point of paraffin (film material) (5 ° C). Heat to above (melting point + 10-20 ° C) to keep paraffin in a molten state (specific gravity about 0.78). Then, float the paraffin on the water in a molten state (less than 1 mm thick). Enzyme cooled to below the melting point of paraffin (about 7 ° C)
Polyethylene glycol (average molecular weight: 400) (core substance: specific gravity: 1.13) in which (protease (20% papain powder)) is dispersed at about 20% concentration is added dropwise. The size of the capsule can be changed by arbitrarily changing the size of the droplet to be dropped. While the polyethylene glycol in which the enzyme is dispersed falls through the paraffin (membrane material) phase due to the difference in specific gravity, a paraffin (membrane material) film is formed around the polyethylene glycol (core material) in which the enzyme is dispersed. Moves to the water phase due to the difference in specific gravity, and is cooled and hardened by water. The obtained capsule has a capsule diameter of 4
〜5 mm, average film thickness about 300 μm, enzymatic encapsulation rate about 3%,
It collapses under light load. Also, since it is made of paraffin, it has excellent moisture barrier properties and is harmless to humans. The obtained capsule is used as a material for a face wash.

る。According to the present invention, capsules can be obtained simply, easily and economically. In addition, it is possible to obtain a reserve type enzyme-containing capsule which is difficult by the conventional method. Also, capsules of any size can be obtained simply by changing the size of the diameter of the drop regardless of solid or liquid. Furthermore, the enzyme can be completely encapsulated because it is less exposed to high temperatures. The obtained capsule can be used as a cosmetic material such as a shaving hot gel, a shaving cream, and a face wash.
