Hydroxypropyl starch ether (HPS) is a natural plant as raw material, modified, highly etherified reaction, and then spray-dried white fine powder, without plasticizer. It is completely different from ordinary starch or modified starch.
Method: hydroxypropyl starch is a chemically modified starch, from propylene oxide and starch etherification reaction, replacing the polymer structure of starch hydroxyl, as an etherified starch.
Physical properties: white (colorless) powder, good fluidity, good water solubility, the aqueous solution transparent colorless, good stability. Stability of acid and alkali, and the temperature is lower than the original starch, hot and cold viscosity changes than the original starch stability. And salt, sucrose mixed with no effect on viscosity. After etherification, the stability and transparency of the ice melt are improved.
Chemical properties: Hydroxypropyl substituents of the starch derivatives of the properties of starch glucose units have three units can be replaced hydroxypropyl, so different degrees of replacement products can be obtained.
Technical index Appearance: white powder, easy to absorb moisture
Solubility: soluble in water, a transparent solution
Viscosity (5% aqueous solution, 20 ° C): 500-20000 mPa · s
PH value (2% aqueous solution): 8-10.5
