Abstract

It is intended to provide a soft capsule film composition excellent in a manufacturing property (such as easy operability), and suitable for a non-animal soft capsule, particularly a seamless capsule, which is safe as a food or a pharmaceutical product, wherein a resulting soft capsule has a sufficient physical strength (such as initial stiffness and burst strength), and is excellent in stability against humidity and heat, disintegratability and releasability from a container or a bag, and capsules are less likely to adhere to one another. The soft capsule film composition contains a non-animal water-soluble polymer, polyvinyl alcohol and/or polyvinylpyrrolidone and a gelling agent as essential components.

[0002] 従来、医薬品等に用いられるカプセル皮膜の原料としては、ゥシゃブタの骨や皮な どを原料とするゼラチンが多く用いられてきた。しかしながら、ゼラチンをはじめとする 動物由来の材料は、狂牛病 (BSE)などの発生を見るに至り、安全性、安定供給等の 観点からその問題性が指摘され、非動物性材料へのシフトに対する社会的要求が高 まっている。  [0002] Conventionally, as a raw material for capsule coatings used for pharmaceuticals and the like, gelatin made mainly from bones and skins of swine pigs has been used in many cases. However, animal-derived materials such as gelatin have seen the occurrence of mad cow disease (BSE), etc., and their problems have been pointed out from the viewpoint of safety, stable supply, etc., and there has been a shift to non-animal materials. The social demand for is increasing.

From the viewpoint of practicality that comprehensively judges strength, disintegration, etc., compared to the above, it is still not enough as a substitute. More specifically, the known soft capsule film has a problem that when it is placed in an environment having a temperature of 25 ° C. and a relative humidity of 50% or more, the film strength rapidly decreases due to moisture absorption. ing.

Regarding the capsule film composition and the effects obtained by using the composition, no description is disclosed or suggested.
