Polyethylene Glycol PEG 20000
Polyethylene Glycol 20000 is widely used in various pharmaceutical preparations, such as injection, local preparation, eye preparation, oral and rectal preparations.
Polyethylene Glycol Miralax at the solid level can be added to the liquid polyethylene glycol to adjust the viscosity for local ointments. Polyethylene glycol mixtures can be used as suppository matrix; The aqueous solution of polyethylene glycol can be used as a suspension or to adjust the viscosity of other suspension media.
Polyethylene glycol and other emulsifiers are used to increase the stability of emulsion.
In addition, polyethylene glycol is also used as film coating agent, tablet lubricant, controlled release material and so on.
Chemical formula H(OCH2CH2)nOH
CAS No.: 25322-68-3
CharacteristIcs:
1. Ethylene oxide condensation;
2. Polyethylene glycol with relatively low molecular weight can be used as solvent,
cosolvent, O/W type emulsifier and stabilizer
3. Solid waxy polyethylene glycol with high relative molecular weight is often used to increase the viscosity and solidification of low molecular weight liquid PEG
4. Polyethylene glycol series products can be used as raw materials for ester surfactants
