- the present invention when used as an excipient, exhibits excellent compression moldability and retention of liquid components in the production of molded articles containing various active ingredients.
- An object of the present invention is to provide a cellulose powder capable of realizing a tablet having sufficient tablet hardness without a tableting trouble and having a sufficient tablet hardness in a simple manufacturing process. Means for solving the problem
- the present inventors have conducted intensive studies to solve the above problems, and as a result, by controlling the powder physical properties of the cellulose powder to a specific range, a cellulose powder having both compression moldability and liquid component retention properties was obtained. The inventors have found that they can be obtained, and have accomplished the present invention.
- the present invention is as follows.
- Senorelose powder having an average degree of polymerization of 150 450, an average particle size of 30 250 xm, an apparent specific volume of more than 7 cm 3 / g, and a polyethylene glycol having a molecular weight of 400 and a retention of 190% or more.
- a molded composition comprising one or more active ingredients and the cellulose powder of the above (1).
- the cellulose powder of the present invention has various properties such as compression moldability and retention properties of a liquid component.
- the composition containing the cellulose powder can be used in addition to a solid active ingredient.
- the active ingredient When the active ingredient is compression-molded, it has the effect of obtaining a molded article having an appropriate hardness in a simple process and having no tableting obstruction in which the liquid ingredient does not ooze out.
- the cellulose powder of the present invention needs to have an average degree of polymerization of 150 to 450. If the average degree of polymerization is less than 150, the compression moldability is insufficient, which is not preferable. On the other hand, if the average weight exceeds 450, the hydrolysis of the raw material cellulose is not sufficiently advanced, so that the cellulose contains a large amount of amorphous portion, and the fibrousness is strong and the elasticity is easily recovered, which impairs the moldability. There is a tendency. On the other hand, if the average degree of polymerization exceeds 450, even if the polyethylene glycol retention rate described later is high, the liquid component oozes out at the time of molding and compression, resulting in tableting failure.
- the average particle size of the cellulose powder of the present invention needs to be 30 to 250 xm. Average grain When the particle diameter is less than 30 ⁇ , the particles are excessively impacted when the particles are atomized, and the retention of the liquid component is undesirably reduced. Further, when the cellulose particles are aggregated and immediately mixed with the active ingredient, the active ingredient is not uniformly dispersed, and the resulting tablet has a large variation in the active ingredient content, which is not preferable. On the other hand, if the average particle size exceeds 250 zm, the active ingredient may be separated and biased during pneumatic transportation, leading to a decrease in content uniformity.
- the apparent specific volume of the cellulose powder of the present invention needs to exceed 7.0 cm 3 Zg. If the apparent specific volume is 7.0 cm 3 Zg or less, sufficient formability cannot be given to a sufficient molded body because of insufficient formability. The larger the apparent specific volume is, the better it is. There is no particular upper limit, but it is usually 13.0 cm 3 / g. 13. If it exceeds OcmVg, the fluidity of the cellulose powder deteriorates, and the cellulose particles tend to agglomerate. When mixed with the active ingredient, the active ingredient is not uniformly dispersed, and the content of the active ingredient in the obtained tablet is reduced. Is not preferred because the variation in
- the cellulose powder of the present invention must have a polyethylene glycol retention rate of average molecular weight 400 of 190% or more. It is preferably at least 200%, particularly preferably at least 250%.
- the cellulose powder of the present invention when the polyethylene glycol having an average molecular weight of 400 has a polyethylene glycol retention of 190% or more, retains the liquid active ingredient when compression-molding a molded article containing a liquid or semi-solid active ingredient, The exudation can be prevented. If the retention rate of polyethylene glycol having an average molecular weight of 400 is less than 190%, when compression-molding with the liquid active ingredient, the liquid component cannot be retained and the liquid component oozes out into the powder layer. This is not preferable because the contact of the molded product becomes coarse, and sufficient mechanical strength cannot be imparted to the molded product, and tableting failure occurs.
- the cellulose powder of the present invention can be obtained, for example, by drying a cellulose dispersion obtained by dispersing a hydrolyzed natural cellulosic substance in an appropriate medium.
- a solid content containing the hydrolyzed cellulose-based substance is isolated from the reaction solution obtained by the hydrolysis treatment, and the solid content is separately dispersed in an appropriate medium.
- the dispersion may be directly dried.
- the natural cellulosic material is a fibrous material derived from natural products containing cellulose such as wood, bamboo, cotton, ramie, sea squirt, bagasse, kenaf, and bacterial cellulose, which can be plant or animal. It preferably has a cellulose I type crystal structure.
- cellulose such as wood, bamboo, cotton, ramie, sea squirt, bagasse, kenaf, and bacterial cellulose, which can be plant or animal. It preferably has a cellulose I type crystal structure.

Water and organic solvents may be used alone or in combination of two or more.After once dispersing in one kind of medium, the medium is removed and dispersed in a different medium. You may. [0023]
- the average particle diameter of the cellulose dispersed particles present in the cellulose dispersion thus obtained must be 50 ⁇ m or more. When the average particle size is less than 50 ⁇ m, the apparent specific volume of the obtained cellulose powder is small even when the cellulose dispersion is dried, and the cellulose powder of the present invention is excellent in compression moldability and liquid component retention. Cannot be obtained.
- a cellulose dispersion having an average particle diameter of less than 50 zm contains a relatively large amount of a cellulose-dispersed fine particle component. Due to the change in structure, even when a dispersion containing a large amount of fine particle components is dried, the retention of liquid components is high, and cellulose powder cannot be obtained.
