<p>Provides a water-containing gel form which exhibits reduced stickiness to the attached material, good sence of use and low irritation to skin, forms no syneresis liquid, has simple composition and is easily prepared. Further, provides a method to adjust arbitrarily crosslinking speed on production of a water-containing gel form using a (meth)acrylic acid-based polymer. (1) a composition for water-containing gel form comprising at least one kind of compound (D) selected from the group consisting of compounds containing a monovalent or divalent metal ion, and a (meth)acrylic acid-based polymer (A), water (C) and a crosslinker (B), which reacts with carboxyl groups, as major components, (2) a water-containing gel form obtained from the composition, (3) a production method of the water-containing gel form and (4) a transdermal formulation, cooling sheet and cosmetics using the water-containing gel form. A production method of a water-containing gel form, wherein crosslinking speed of the (meth)acrylic acid-based polymer is adjusted by adding at least one kind of metal salt (component D') selected from the group consisting of metal salts containing a monovalent or divalent metal ion when the (meth)acrylic acid-based polymer (component A) is crosslinked by mixing with an aluminum-containing compound (component B') and water (component C).</p> |
