How does ethyl cellulose act as a large particle binder

Answer:

Ethylcellulose (DS: 2.3-2.6) The most commonly used mixed solvents are aromatic hydrocarbons and alcohols. Aromatic hydrocarbons can be benzene, toluene, ethylbenzene, xylene, the amount of 60-80%; alcohol available methanol, ethanol, the amount of 20-40%.
Ethyl cellulose due to its water insoluble, mainly for tablet adhesives and film coating materials, can also be used as a skeleton material blockers, the preparation of various types of skeleton sustained-release tablets; used as a mixture of materials preparation coating Sustained release tablets, sustained-release pellets; used as encapsulation materials to prepare sustained-release microcapsules, so that the sustained release of efficacy, to avoid the role of some water-soluble drugs prematurely; can also be used for a variety of pharmaceutical formulations for dispersant, , Water-retaining agent, to prevent the deterioration of drugs and improve the safe storage of tablets.
This product is white or light gray flow of powder or particles, odorless and tasteless, softening point 135-155 ℃, false weight 0.3-0.4 /, the relative density of 1.07-1.18, the melting point of 165-185 ℃, insoluble in water, soluble In a variety of organic solvents such as ethyl acetate, benzene, toluene, acetone, methanol, ethanol, etc., where k specifications have high hardness, strength and heat resistance, N specifications with solubility and wide range of compatibility and soft Sex, T-only organic solvents that are soluble in hydrocarbons and insoluble in oxygen-containing atoms.
