摘要:
An object of the present invention is to provide a water-soluble acrylate polymer that can form a gelling base. When used in forming a poultice or cooling sheet, the gelling base not only imparts desirable stretchability, but also has an appropriate reaction rate with a polyvalent metal. The gelling base is free from gel penetration to the back side of a support or gel seeping from the support while the gel is being cured, and is easily applied to the support. When the gelling base is gelated by being allowed to stand under the conditions of 25°C and a relative humidity of 60%, the gel strength is 3,200 to 7,000 dyn/cm 2 after standing for 7.5 hours and 5,000 to 9,000 dyn/cm 2 after standing for 200 hours, and satisfies the following relationship: Gel strength after standing for 7.5 hours] ≤ Gel strength after standing for 200 hours.

摘要:
The present invention relates to a water-soluble polymer composition which comprises a water-soluble poly(meth)acrylic polymer and a gelation rate retarding agent, and a composition for forming a plaster layer of a skin patch which is obtainable by adding a polyvalent metal compound to the 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 hardening of the gel. When the water-soluble polymer composition is used for forming a plaster layer of a skin patch, therefore, additive ingredients can be uniformly mixed and the procedure for coating to a support can be facilitated.
