Which polymer are used in sustained release drug formulation?
A combination of various polymers are used such as Hydroxypropyl cellulose, carboxymethyl cellulose and many others. These sustained release (XR, ER, SR) tablets may or may not be film coated as well.
What is the molecular formula of Cellulose?
it's C6H7O2(OH)3
What is the composition of linen?
Linen has a very complicated composition, which should be sought in some reference source. It is largely cellulose, a natural carbohydrate polymer, that may have many variations in molecular weight and possible heteroatoms.
What is the molecular weight for Vitamin E?

Sodium carboxymethylcellulose Molecular weight?
This is a chemical used in many products like detergents, tooth pastes, shampoos, conditioners, ice cream, pharmaceuticals, water based paints, and many more.. It is manafactured by treating cellulose with NaOH and chloro acetic acid. In this process the -OH groups of the cellulose ring are replaced by -CH2COONa groups
Which is the best viscosity agent Sodium Carboxy methyl cellulose or Calcium Carboxy methyl cellulose?
Sodium Carboxymethyl cellulose will be better viscosifier as compared to calcium carboxymethyl celluose.Since during washing process sodium chloride will be removed as impurities therefore leading to pure Na CMC with viscosity depending upon the molecular weight of wood pulp or cotton linter.
What is the common name of sodium carboxymethyl?
cellulose
What is the molecular weight of cellulose acetate butyrate?
Typically 20,000 to 60,000. Cellulose is natural macro molecule without any specific size or molecular weight. The same applies to the esters of cellulose.
What is the HLB value for carboxymethyl cellulose?
The value of HLB is 10-12.
Which high molecular weight substances are made up of repeating units of these molecules?
starch and cellulose
Which polymer are used in sustained release drug formulation?
A combination of various polymers are used such as Hydroxypropyl cellulose, carboxymethyl cellulose and many others. These sustained release (XR, ER, SR) tablets may or may not be film coated as well.
Why are use Carboxymethyl cellulose in cake?
Probably a stabilizer, to help bind everything together to aid rising (cost cutting; that way less mixture is needed per cake).
What ingredients are used in KY gel?
I belive that KY intense gel is to make your sex life more intense while in bed.
What is the molecular formula of Cellulose?
it's C6H7O2(OH)3
What is the molecular weight of chymotrypsin?
It has a molecular weight of 21,600 Daltons
What is the molecular weight and molecular formula of potassium humate?
molecular structur C9H8K2O4molecular weight: 258.35
