THE DIFFERENCE IS THAT OF VISCOSITY .... HPMC K15M (15 cps)
HPMC K100M (100000 cps )
k4m (4000 cps )and k15m (15cps) differs in viscosity they are two grades of hpmc polymer by Ajit ajit5_incredible@yahoo.com
viscosity of hpmc k4m was 4000cps.
cps stands for centipoise.They have different viscosities.
METHOCEL is a well known trademark of The Dow Chemical Company manufacturing cellulose ethers for various industries. Methocel is a trademark for methycellulose whereas HPMC E5 is Hydroxypropyl Methyl Cellulose with very low viscosity of 5 CPS (centipoise) used as rheology modifier as well as water retaining agent for film formation, synthetics adhesives as well as tablet coating. It has excellent water retaining properties. Samsung fine Chemicals, SE Tylose are one of the competitors of The Dow Chemical Company in the global market along with many Chinese companies.
The term HPMC can be HydroxyPropyl MethylCellulose is a science term. It is is the category of chemistry. It is a a synthentic compound that is used in eye and oral medications.

If you mean HPMC: Hydoroxypropylmethylcellulose then you need to: 1-heat 100ml of DW (deionized water) to 80-90c 2-weight HPMC grams you need to dissolve(1-5%) 3-added HPMC gradually to about 1/4 of water(25ml) while strong mixing is needed 4-then prepare 3/4 of left water with ice in it 5-then added ice water to solution while mixing and you will end in clear solution of HPMC
HPMC, Ethyl cellulose, CAP..
E for excellent elephant
K means 1000 as a multiplier of 1000
K means 1000 as a multiplier of 1000
Methocel (HPMC) is soluble in cold water, forming a viscous colloidal solution; practically insoluble in chloroform, ethanol, and ether, but soluble in mixtures of difernt organic solvents.
