It appears odorless and tasteless white powder. It will form transparent solution of great viscosity while slowly dissolved into water. The viscosity of 0.5% solution is about 1000cp. The viscosity is engendered by the dissociation of numerous anions and hence causes the growth of molecular chain not by expansion of water absorption that normally happens to CMC and sodium alginate. The viscidity is about 15-20 times higher than carboxymethyl cellulose sodium and sodium alginate, carrageenen,Geltin etc.  It shows high alkal... [详细介绍]
