Kodi Polyethylene Glycol CAS 25322-68-3 ndi chiyani?

Polyethylene glycol ili ndi makhalidwe osiyanasiyana kutengera kulemera kwake kwa mamolekyu, kuyambira zakumwa zopanda mtundu komanso zopanda fungo mpaka zinthu zolimba ngati sera. Zomwe zimakhala ndi kulemera kwa mamolekyu a 200-600 zimakhala zamadzimadzi kutentha kwa chipinda, pomwe zomwe zimakhala ndi kulemera kwa mamolekyu opitilira 600 pang'onopang'ono zimakhala zolimba pang'onopang'ono. Makhalidwewo amasiyananso ndi kulemera kwapakati kwa mamolekyu. Kuyambira madzi opanda mtundu komanso opanda fungo mpaka madzi olimba ngati sera.
