Polyacrylic Acid-Based Pharmaceutical and Quasi-Drug Ingredients
ARONVIS®, JUNLON®, RHEOGIC®, JURYMER®
Features
Polyacrylic acid (sodium polyacrylate) is an anionic polymer containing numerous carboxyl groups (-COOH) in its molecules. Aqueous solutions of linear polyacrylic acid (sodium polyacrylate) form viscous, adhesive gels with controlled stringiness. Combining different polyacrylic acids (sodium polyacrylates) with crosslinking agents enables adjustment of strength and adhesion to produce water-resistant gels. These technologies are used not only in pharmaceutical poultices but also in a wide range of non-pharmaceutical products such as cooling sheets and poultices, as well as cosmetics.
