Abstract
An object of the present invention is to improve the hardness of the capsule film of a hard capsule. The present invention improves the hardness of the capsule film of a hard capsule by adding a starch decomposition product, and/or at least one clay mineral selected from the group consisting of talc, bentonite, and kaolin, to a hard capsule film.
Claims28
A hard capsule comprising a film containing a base and a hardness improving agent,
- the base being at least one member selected from the group consisting of cellulose compounds, polyvinyl alcohol, and polyvinyl alcohol copolymers;
- and
- the hardness improving agent being at least one member selected from the group consisting of starch decomposition products having a DE value of more than 11 and less than 40, and two or more kinds of starch decomposition product combined to have a calculated DE value of more than 11 and less than 40 (provided that the two or more kinds of starch decomposition product exclude starch decomposition products solely having a DE value of 5 or less and monosaccharides).
A hard capsule-preparing solution comprising a base and a hardness improving agent,
- the base being at least one member selected from the group consisting of cellulose compounds, polyvinyl alcohol, and polyvinyl alcohol copolymers;
- and
- the hardness improving agent being at least one member selected from the group consisting of starch decomposition products having a DE value of more than 11 and less than 40, and two or more kinds of starch decomposition product combined to have a calculated DE value of more than 11 and less than 40 (provided that the two or more kinds of starch decomposition product exclude starch decomposition products solely having a DE value of 5 or less and monosaccharides).
A hard capsule comprising a film containing a base and a hardness improving agent,
- (i) the base being at least one member selected from the group consisting of cellulose compounds, polyvinyl alcohol, and polyvinyl alcohol copolymers;
- the hardness improving agent being at least one member selected from the group consisting of talc, bentonite, and kaolin;
- the amount of talc contained in the hard capsule being more than 10 wt % and not more than 50 wt % based on 100 wt % of the total film components of the hard capsule, excluding moisture;
- the amount of bentonite contained in the hard capsule being more than 0.5 wt % and less than 10 wt % based on 100 wt % of the total film components of the hard capsule, excluding moisture;
- and
- the amount of kaolin contained in the hard capsule being not less than 10 wt % and not more than 50 wt % based on 100 wt % of the total film components of the hard capsule, excluding moisture.
A hard capsule-preparing solution comprising a base and a hardness improving agent,
- (i) the base being at least one member selected from the group consisting of cellulose compounds, polyvinyl alcohol, and polyvinyl alcohol copolymers;
- the hardness improving agent being at least one member selected from the group consisting of talc, bentonite, and kaolin;
- the amount of talc contained in the hard capsule being more than 10 wt % and not more than 50 wt % based on 100 wt % of the total components of the preparing solution, excluding solvent;
- the amount of bentonite contained in the hard capsule is more than 0.5 wt % and less than 10 wt % based on 100 wt % of the total components of the preparing solution, excluding solvent;
- and
- the amount of kaolin contained in the hard capsule being not less than 10 wt % and not more than 50 wt % based on 100 wt % of the total components of the preparing solution, excluding solvent.
