Abstract: The present invention addresses the problem of providing a double-layer seamless soft capsule having a water-soluble composition as its fill, and by preparing a capsule shell from an ultraviolet-curing resin composition, a double-layer seamless capsule is made which consists of a capsule shell and a water-soluble composition as a fill and where volatility of the fill due to permeation through the shell is low.

Abstract: When preparing a soft capsule shell by forming a film from a composition for a soft capsule shell comprising a base containing either gelatin or a mixture of starch and carrageenan as a main component and a plasticizer containing sorbitol, maltitol and glycerin as main components, it is possible to provide a soft capsule in which the soft capsule shell thereof does not easily soften and the surface of the soft capsule shell is resistant to adherence and which has excellent gloss and transparency even if the plasticizer contains glycerin.
