Product Description:
Polyethylene glycol thiab polyethylene glycol fatty acid esters yog dav siv hauv kev lag luam tshuaj pleev ib ce thiab kev lag luam tshuaj. Vim hais tias polyethylene glycol muaj ntau yam zoo heev: dej-soluble, tsis-volatile, physiologically inert, mos, lubricating, thiab ua rau daim tawv nqaij moist, mos, thiab qab ntxiag tom qab siv. Polyethylene glycol nrog cov txheeb ze sib txawv molecular pawg pawg tuaj yeem raug xaiv los hloov cov viscosity, hygroscopicity thiab cov qauv tsim ntawm cov khoom.
Polyethylene glycol (Mr <2000) uas tsis muaj qhov hnyav molecular yog tsim rau cov neeg sawv cev ntub dej thiab cov khoom sib xws, siv rau hauv qab zib, tshuaj pleev, tshuaj txhuam hniav thiab shaving cream, thiab lwm yam, thiab kuj tsim nyog rau cov khoom tu plaub hau tsis tu, muab cov plaub hau zoo nkauj. . Polyethylene glycol nrog qhov hnyav molecular (Mr> 2000) yog tsim rau lipsticks, deodorant sticks, soaps, shaving soaps, foundations thiab tshuaj pleev ib ce zoo nkauj. Hauv cov tshuaj ntxuav tes, polyethylene glycol kuj tseem siv los ua cov tshuaj tua kab mob thiab ua kom tuab. Hauv kev lag luam kws tshuaj, siv los ua lub hauv paus rau cov tshuaj pleev, tshuaj pleev, tshuaj pleev, tshuaj pleev thiab tshuaj suppositories.
