Peg300 Polyethylene Glycol 300

I-Polyethylene glycol kunye ne-polyethylene glycol ene-acid ester isetyenziswa ngokubanzi kwizithambiso nakumashishini amayeza. Ngenxa yeepropathi ezilungileyo ze-polyethylene glycol, ukunyibilika kwamanzi, okungagungqiyo, inertia yomzimba, ukuthamba, ukuthambisa kunye nokumanzisa, ulusu oluthambileyo, ukusetyenziswa kwemvakalo emnandi, njl njl. I-polyethylene glycol enamanqanaba ahlukeneyo okuma kobunzima beemolekyuli. I-Polyethylene glycol (Mnu <2000) enobunzima obuncinci beemolekyuli zilungele ukumanzisa iiarhente kunye nolawulo lokungaguquguquki. Isetyenziselwa ukhilimu, into yokuthambisa, intlama yamazinyo kunye nokucheba cream Ikwasebenza nakwimveliso yeenwele engakhange ihlanjwe, inika iinwele ukubengezela okuqaqambileyo. I-Polyethylene glycol (Mnu 2000) enobunzima obuphezulu beemolekyuli ilungile kwimilebe yomlomo, intonga yokuhambisa, isepha, isepha yokucheba, isiseko kunye nezithambiso Kwi-arhente yokucoca, i-polyethylene glycol ikwasetyenziswa njenge-suspension kunye ne-thickener. Kwishishini lokuxuba amayeza, lisetyenziswa njenge matrix yokuthambisa, i-emulsion, ioyile, into yokuthambisa kunye ne-suppository. I-Polyethylene glycol (enjenge-polyethylene glycol NF, yenza iChemical Co) efumanekayo ukuba ithengiselwe ukutya kunye nokusetyenziswa kweziyobisi ilungele ukusetyenziswa kwezithambiso. Ukusetyenziswa kwe-methoxy polyethylene glycol kunye ne-polypropylene glycol kuyafana ne-polyethylene glycol.
I-Polyethylene glycol yipolmer engenakunyibilikiswa ngamanzi. Inokuhambelana nezinto ezininzi ezinobuninzi obuphezulu. Inokuhambelana okungalunganga kunye nezinto ezisezantsi ze-polar kunye nokuhambelana okuhle ne-polyethylene glycol enobunzima obuphantsi beemolekyuli. Isikhonkwane sinokuhambelana neprotein, isitatshi esine-oxidized, nitrocellulose, polyvinyl acetate kunye ne-zein. Ayinyibiliki inyosi, i-oyile ye-castor, i-gelatin, i-Arabhu, i-oyile yezimbiwa, i-oyile ye-olive kunye neparafini.
