Sodium polyacrylate is a kind of high-molecular compound with a hydrophilic group that looks like odorless and tasteless white powder. It will form transparent solution of great viscosity while slowly dissolved into water. The viscosity is engendered by the dissociation of numerous anions and hence causes the growth of molecular chain.
Viscidity: about 15-20 times higher than carboxymethyl cellulose, sodium alginate, carrageenan, gelatin etc.
