Hydroxypropyl methyl cellulose is a non-ionic cellulose ether. It has

uncommon and valuable composite physical and chemical properties,

according to difference replacement degree of replacement group and modified degree.

(1)Water-soluvility

It can dissolve in water at any ratio,their max.concentration depend on their viscosity.

(2)None ionic charge
It belong to non-ionic type,will not act to metal salt and ionic

organic compound,complex-forming to insluble precipitate.

(3)Heat gelation
When their water solution is heated to certain temp.,it will formen to gel.After

having been cooled the formed gel becomes to solution again.

(4)Surface activity
In solution,it provids a surface activity,attaining to considered emulsifying and protective colloid and phase stabilization.

(5)Metabolic inert
It is used as additives for food and medicament.It will not be metabolized,and will not provide heat energy in food(6)Anti-enzyme
It has better antienzyme ability.When longterm storage,it has good viscosity stability.

(7)PH stability
It has a broad PH range.(PH:3~11)

(8)Water retention
After its porous surface having absorbed moisture,it can preserve moisture.

(9)Thickening Its water solution system has thickening power.The thickening degree is related to the used viscosity of

product and type of compound.

(10)Film formation
It can make clean and pure,tough and tensile,flexible film,and has excellent

(11)Bonding
It can make clean bonding agent for pigment,tobacco product,and paper etc.,and has excellent properties,is also used in coating.

(12)Lubricating
It used in rubber,asbestos,cement,and ceramic product,thus decreasing its friction force,and modifying pumping of concrete.

(13)Suspension
It can prevent solid particles from precipitating,thus inhibiting formation of deposition.

(14)Protective colloid
It can prevent droplet and particles to be changed to agglomerate state.

(15)Emulsification
Because of decreasing surface and interfacial tension,and thickening water phase,thus it can stabilize emulsion.Typical physicochemical properties
