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

Polyethylene glycol ili ndi katundu wosiyana malinga ndi kulemera kwake kwa maselo, kuchokera ku zakumwa zopanda mtundu komanso zopanda fungo za viscous mpaka zolimba za waxy. Omwe ali ndi mamolekyu olemera a 200-600 ndi zakumwa kutentha kwa firiji, pamene omwe ali ndi kulemera kwa maselo pamwamba pa 600 pang'onopang'ono amakhala olimba. Zinthuzo zimasiyananso ndi kulemera kwa maselo. Kuchokera pamadzi opanda mtundu komanso osanunkhiza a viscous mpaka olimba.
