一般描述

聚乙二醇（PEG）是环氧乙烷和水通过缩合反应产生的聚合物。当暴露在空气中时，PEG易被氧化降解。尽量减少PEG暴露于高度和/或暴露于氧气或添加抗氧化剂，可以限制降解量。PEG在储存过程中不会水解或变质。PEG不支持霉菌生长。
聚乙二醇（PEG）被用于洗涤剂、乳化剂、香皂、金属加工过程、药物制剂和化妆品中。PEG常被用作润滑剂。它也被用于色谱的固定相中。PEG可防止乳液中的晶体形成。
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.
