Document Type and Number:
WIPO Patent Application WO/2011/013546
Kind Code:
A1
Abstract:
Disclosed are a water-soluble polymer composition which comprises a water-soluble poly(meth)acrylic acid polymer and a gelation rate retarding agent, and a composition for forming plaster layer of skin patch which is obtained by adding a polyvalent metal compound to said water-soluble polymer composition.
When a polyvalent metal compound is added, the aforesaid water-soluble polymer composition shows an appropriate induction period before the start of the gel hardening. When the water-soluble polymer composition is used for forming a plaster layer of a skin patch, therefore, added components can be uniformly mixed and the procedure for coating to a support can be facilitated.
