General description
聚乙二醇（PEG）是一种亲水性聚合物。它可以通过环氧乙烷的阴离子开环聚合反应而进行合成，产生不同的分子量和端基。当PEG交叉成网状建构，能够有高水含量，形成水凝胶PEG，是很好的生物材料因为它不会引起免疫应答。
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.
