Hydroxypropyl Starch Ether
First, Product overview
Hydroxypropyl starch ether is an ionic starch ether produced by a series of chemical and physical reactions under alkaline conditions. Hydroxypropyl starch ether is a non-toxic tasteless irregular phosphorus tablet or white powder, which can be dissolved in cold water to form a transparent or translucent viscous liquid. It has the properties of thickening, adhesion, dispersion, emulsification, suspension, adsorption, surface activity, water retention and so on.
