Determination of Distillation Range of Polyethylene Glycol (CAT#: STEM-PPA-0154-YJL)

Introduction

Polyethylene glycol is a high molecular polymer with a chemical formula of HO(CH2CH2O)nH, non-irritating, slightly bitter taste, good water solubility, and good compatibility with many organic components. It is widely used in various pharmaceutical formulations such as injections, topical formulations, ophthalmic formulations, oral and rectal formulations.<br /><br />Solid grade polyethylene glycol can be added to liquid polyethylene glycol to adjust viscosity for topical ointment. Polyethylene glycol mixtures can be used as suppository bases. The aqueous solution of polyethylene glycol can be used as a suspending agent or used to adjust the viscosity of other suspension media. Polyethylene glycol is used in combination with other emulsifiers to increase the stability of the emulsion. In addition, polyethylene glycol is also used as a film coating agent, tablet lubricant, controlled release material, etc.
