That is, in the present invention, 1 to 30 mol% of the constituent monomers are 2-acrylamide-2-methylpropanesulfonic acid, 70 to 99 mol% is acrylic acid, 20 to 60 mol% of the acid is neutralized, fine powdery and fine. A patch for patch comprising a water-soluble copolymer (a), a polyhydric alcohol (b), a polyvalent metal compound (c) and water (d) as an essential component having a content of a reaction monomer of 0.5% by mass or less, and a patch for skin formed using the base Jay. |
