Name: Polyethylene Oxide
CAS No.: 25322-68-3
Package: 1kg/bag; 5kg/bag; 20kg/drum; 25kg/drum
Appearance: White to off-white, free-flowing powder; with a slight ammonia odor. Soluble in water and many common organic solvents, such as acetonitrile, chloroform, dichloromethane, insoluble in aliphatic hydrocarbons, ethylene glycol and ethanol.
Quality Standard: CP2020; USP; EP
Features:
Polyethylene Oxide films have excellent lubricity when wet, and this property has been used to improve medical device coatings.
Polyethylene Oxide can be used as a tablet binder. Polyethylene Oxide with large molecular weight delays drug release by swelling the hydrophilic matrix.
Advantages:
■Polyethylene Oxide has low toxicity when applied to various routes of drug administration
■Rapid hydration and gel formation when used in hydrophilic matrix tablets
■Broad molecular weight range allowing for greater formulation flexibility
Application:
Application | Dosage |
Sustained release skeleton material | 10-30% |
Binder | 1-10% |
Storage: Preserve in tight, light-resistant containers. No storage requirements specied.
