Title:

CATAPLASM AND ITS PRODUCTION

Document Type and Number:

Japanese Patent JP2000053564

Kind Code:

A

Abstract:

To obtain a cataplasm having excellent adhesiveness, shape-retaining properties, having neither oozing out of a paste to a substrate nor reduction in adhesion showing excellent stability of gel paste with time and high safety by including a specific acrylic polymer as a component.

This cataplasm comprises a gel paste obtained by mixing (A) a carboxyl group-containing acrylic polymer having ≤0.1 wt.% unreacted monomer with preferably (B) a polyvalent metal compound. The mixing ratio of the gel paste comprises, for example, 1-20 wt.% of the acrylic polymer such as a (meth)acrylic acid/ (meth)acrylate copolymer 1-30 wt.%; of a humectant such as glycerol, 0.001-1 wt.% of a polyvalent metal compound such as aluminum hydroxide, 1-10 wt.% of an inorganic additive such as kaolin, 0.5-10 wt.% of a pharmacodynamic component and 40-80 wt.% of water.
