Abstract: The invention is to provide a method for producing a soft capsule type external preparation (and a softening liquid (L) used for the production thereof, and an external preparation composed of such a capsule body (C)) which can be stably stored and leaves no film residues when rubbed with the finger when used as an external preparation although the external preparation is structured only as a capsule body (C) substantially having no external solution. An original capsule body (c) in which at least the external surface region inside an alginate capsule is present in the form of a polyvalent metal alginate is contacted with a softening liquid (L) composed of an aqueous solution comprising both “a basic amino acid (1)” and “an acid (2) selected from an organic acid or a phytic acid,” thereby impregnating the softening liquid (L) into the original capsule body (c) to obtain the capsule body (C).

Abstract: The invention provides edible pearly capsules containing a large amount of an oleaginous substance as the core substance. The above capsules can be provided by the method which comprises contacting liquid drops (a) of a composition comprising an aqueous solution of a water-soluble macromolecular substance at least a portion of which is marmelo mucilage (a.sub.1), an oleaginous substance (a.sub.2), e.g. animal or vegetable oil, a water-soluble polyvalent metal salt (a.sub.3), e.g. calcium chloride, and sodium chloride (a.sub.4) with an aqueous solution of a water-soluble salt of alginic acid (b) to thereby form a water-insoluble film of alginic acid salt on the outer surface of said liquid drops (a).
