Ukusetyenziswa
Iimpawu zeGlycerol ziyenza ibe luncedo kwiindlela ezininzi. Amaqela amathathu e-hydroxyl kwi-glycerol avumela ukudityaniswa okukhulu kwe-hydrogen okunika i-glycerol ubume bayo obufana ne-syrup kunye ne-hygroscopic. Malunga ne-40% yokusetyenziswa kwe-glycerol kukwiimveliso zokhathalelo lomntu ezifana nezinto zokuthambisa, isepha, ii-shampoo, ii-lotions, i-mouthwash, kunye ne-toothpaste. Iimpawu zeGlycerol ezihambelana ne-hygroscopic zenza ukuba ibe yi-moisturizer elungileyo kwiimveliso zesikhumba. Enye i-25% yemveliso yonyaka ye-glycerol isetyenziswa kwimveliso yokutya. Kwishishini lokutya, i-glycerol isetyenziswa njenge-moisturizer, njengesinyibilikisi sombala wokutya kunye ne-syrups, ukuthintela ukwakheka kweswekile kwiilekese kunye nee-icing, njengesigcini, kunye ne-sweetening agent. Malunga ne-10% yokusetyenziswa kwe-glycerol iya ekucutshungulweni kwecuba, apho itshizwa kumagqabi ecuba ngaphambi kokuba anqunyulwe ukuze asebenze njenge-moisturing agent. I-Glycerol inenzuzo eyongezelelweyo yokunika incasa emnandi kwicuba elihlafunwayo. I-25% eseleyo yokusetyenziswa kwe-glycerol isasazwa phakathi kweendlela ezahlukeneyo zokusetyenziswa kwimizi-mveliso. Isetyenziswa kwi-cough syrups kunye namayeza e-elixir. Kwimizi-mveliso, i-glycerol ifumaneka kwizithambiso, kwi-plasticizers, kwi-adhesives, kwi-antifreezes, kwi-resins, nakwi-insulating foams. Ngaxa lithile yayisetyenziswa phantse kuphela kwimo yayo ene-nitrate njengesiqhushumbisi (jonga i-Nitroglycerin), namhlanje ebiza malunga ne-3% yokusetyenziswa kwayo.
I-Glycerol sisithambisi esisetyenziswa kwii-moisturizer. Iyakwazi ukubopha amanzi kwaye iyakwazi ukutsala nokufunxa amanzi emoyeni, ngaloo ndlela inceda ulusu lugcine umswakama. I-glycerin ifundwe kakhulu ngenxa yezakhono zayo zokufumisa. Ngokusekelwe kwidatha ekhoyo, i-glycerin iye yasekwa njengearhente elungileyo yokufumisa ulusu. Ubuncinane inxalenye yomsebenzi wayo ibangelwa kukwenza kube lula ukusabela kwe-enzyme eluswini, ngaloo ndlela ikhuthaza ukususwa kwe-corneocyte. I-glycerin ikwaphucula iimpawu zokusasazeka kweekhrimu kunye neeloshini. Lulwelo olucacileyo, olune-syrup olwenziwe ngokudibanisa amanzi kunye namafutha ngokweekhemikhali oluhlala luvela kwioyile yemifuno. Nangona i-glycerin ingakhange ibonakale ibangela i-allergies, inokuba yi-comedogenic kwaye icasule ii-mucous membranes xa isetyenziswa kwizisombululo ezixineneyo.
IGlycerol isetyenziswa kokubili ekulungiseleleni isampuli kunye nokwenziwa kwejeli kwi-polyacrylamide gel electrophoresis. IGlycerol (5-10%) yonyusa uxinano lwesampuli ukuze isampuli ibe maleko ezantsi kwequla lejeli. IGlycerol ikwasetyenziswa ukunceda ekubunjweni kweejeli zegradient kunye njenge-protein stabilizer kunye ne-storage buffer component.
Njenge-solvent, i-humectant, i-plasticizer, i-emollient, i-sweetener, ekwenzeni i-nitroglycerol (i-dynamite), izinto zokuthambisa, isepha zolwelo, ii-liqueurs, ii-confectioneries, i-blacking, i-printing and copying inks, ii-lubricants, i-elastic glues, i-lead oxide cements; ukugcina amalaphu ethambile; ukugcina ushicilelo kwikotoni; kwiirola zokuprinta, ii-hectographs; ukugcina iqhwa kwi-windscreens; njenge-antifreeze kwiimoto, ii-gas meter kunye ne-hydraulic jacks, kwi-shock absorber fluids. Kwi-fermentation izondlo ekuveliseni ii-antibiotics. Uncedo lwe-Pharmaceutic (i-humectant; i-solvent, isithuthi). ULeffingwell kunye noLesser (op. cit.) banika iindlela ezili-1583 ezahlukeneyo zokusetyenziswa.
