概述
有轻微特殊气味。微有吸湿性。遇热易熔化。溶于水和乙醇
聚乙二醇（PEG）是非离子、亲水、无毒的聚合物。它广泛用于基于聚合物的新兴药物递送领域。PEG有不同的分子量。它有助于蛋白质和核酸的纯化和晶体生长。PEG和葡聚糖一起产生生物材料纯化所需的聚合物双水相体系。它还可与细胞膜相互作用，从而促进细胞融合
应用：
聚乙二醇已用于制备基于甲基纤维素(MC)的聚合物电解质，它还被用作分析纳滤膜的截留分子量和截留研究的溶剂。
Usually used to modify therapeutic proteins and peptides to increase their solubility and lower their toxicity.
Polyethylene glycol is used in electron microscopy. It is used as a solvent, a dye carrier in inks and a dispersant in water based coatings. Its derivatives like PEG esters are used as surfactants. In the textile industry, it is used as a lubricant, softener, dye carrier dispersant and an anti-static agent. It finds application in personal care products like skin creams, lotions and bath gels.
