HPMC manufacturer-4 ways to identify the quality of HPMC
Hydroxypropyl methyl cellulose (HPMC) is an odorless, tasteless, non-toxic white powder. After being fully dissolved in water, hydroxypropyl methyl cellulose will form a transparent viscous colloid.
Comparison of the advantages and disadvantages of HPMC：
1.The pure hydroxypropyl methyl cellulose HPMC has a loose visual condition and a small bulk density. The scale is 0.3-0.4/ml.
The adulterated HPMC has very good fluidity and feels heavier, which is significantly different from the genuine appearance.
2.The pure hydroxypropyl methyl cellulose HPMC aqueous solution is clear, the light transmittance is high, and the water retention rate is >97%.
The adulterated HPMC aqueous solution is relatively dirty, and the water retention rate is difficult to reach 80%.
3.Pure hydroxypropyl methylcellulose HPMC should not smell ammonia, starch and alcohol.
The adulterated HPMC can usually smell all kinds of smells.
4.Pure hydroxypropyl methylcellulose HPMC powder is fibrous under a microscope or magnifying glass.
The adulterated HPMC can observe granular solids or crystals under a microscope or magnifying glass.
