  3.Properties:

  (1)Appearance:HEMC is a white or light gray pellet or fibril power with odorless and tasteless.
  (2)Solubility:It can dissolve in other cold or hot water ,hardly dissolve in all arganic solvents.
  (3)PH stable:viscosity change is small when PH is within 2-12 but decrease when     PH low than the range.
  (4)Particle size:100 screen pass rate: ≥ 90%
  (5)Density:0.30~0.60g/cm³
  (6)Thicker agent, suspending agent, adhesive agent, emulsification agent, coating agent, water keeping agentand protective agent,etc. Whater keeping ability is better MC. It is stable in viscosity and anti-mildew and dispersant is stronger HEC.

  4.Application:
  HEMC is mainly used as adhesive protective gelatin, thicker agent and stabilizing agent as well as additives to make emulsion, frozen gelatin, lotion, eye clear agent, suppository and tablets.
  
  5.Packing,storage,transportation:
  It is packed in 20kg bags,prevent from raining and fire,wet must be avoided
