Ingcaciso yeMveliso:
I-Polyethylene glycol kunye ne-polyethylene glycol fatty acid esters zisetyenziswa ngokubanzi kwishishini lokuthambisa kunye neshishini loxubo mayeza.Ngenxa yokuba i-polyethylene glycol ineempawu ezininzi ezintle kakhulu: i-soluble yamanzi, i-non-volatile, inert ye-physiologically, i-mild, i-lubricating, kwaye yenza ulusu lufume, luthambile kwaye lube mnandi emva kokusetyenziswa.I-Polyethylene glycol kunye namaqhezu ahlukeneyo obunzima be-molecular inokukhethwa ukutshintsha i-viscosity, i-hygroscopicity kunye nesakhiwo sombutho wemveliso.
I-Polyethylene glycol (Mnu<2000) enesisindo esiphantsi se-molecular ifanelekile kwi-agent yokumanzisa kunye nomlawuli ohambelanayo, osetyenziswe kwi-cream, i-lotion, i-toothpaste kunye ne-cream yokucheba, njl. .I-Polyethylene glycol enobunzima obuphezulu be-molecular (Mr> 2000) ifanelekile kwi-lipstick, i-deodorant stick, iisepha, iisepha zokucheba, iziseko kunye nezithambiso zobuhle.Kwizinto zokucoca, i-polyethylene glycol iphinda isetyenziswe njenge-agent yokumisa kunye ne-thickening.Kumashishini amayeza, asetyenziswa njengesiseko se-ointments, i-creams, i-ointments, i-lotions kunye ne-suppositories.
Umqulu:25 kgs/ibhegi okanye njengoko ucela.
Ugcino:Gcina kwindawo engenamoya, kwindawo eyomileyo.
Umgangatho wesiGqeba:Umgangatho wamazwe ngamazwe.
