In the putty powder, it plays three roles of thickening, water retention and construction. Thickening: Cellulose can be thickened to suspend and keep the solution uniform up and down, and resist sagging. Water retention: Make the putty powder dry slowly to assist the ash calcium to react under th...Read more »

01. The difference between fake hydroxypropyl methyl and high-quality hydroxypropyl methyl Appearance: Pure starch HPCM appears too homogeneous, between 0.3 and 0.4 g/ml. Amylum binds to starch so HPCM is a liquid and less stressed than regular detoxifiers. Conditions: starch full of starch, hpm ...Read more »
