3.Resistance to Oils, Greases and solvents .
4.Water binding by hydrogen bonding.
5.It acts as an emulsifier and stabilizer. It binds the free water in the system.
USE IN FOLLOWING INDUSTRIES
1.In pharmaceutical industries it is used as disintegrating agent in tablet formulation,tablet binding, film forming, jelly forming flocculent.
