Properties

l.Good solubility in water, its solution is tiansparent and colorless,and good stability

2.1t works stably in acid,alkali condition.The gelatinization temperatiue is lower than the native starch.

The viscosity changes little than native starch's as the temperatiue changes.

3.It is compatible with salt,sugar etc.

Advantage

1 .Rapid thickening ability is available.

2.It has medium viscosity wliile high water retention.

3.It can improve the cellulose ether's fimction such water retention, open time,anti-sagging when used with cellulose ether together so it can reduce the dosage of cellulose ether like hydioxyporpyl methyl cellulose to save more cost.
