Ukusetshenziswa
Izakhiwo zeGlycerol ziyenza ibe usizo ezinhlotsheni eziningi. Amaqembu amathathu e-hydroxyl ku-glycerol avumela ukubopha okukhulu kwe-hydrogen okunikeza i-glycerol ukuthungwa kwayo okuyingqayizivele kwe-syrupy viscous kanye nohlamvu lwe-hygroscopic. Cishe u-40% wokusetshenziswa kwe-glycerol kungokwemikhiqizo yokunakekela umuntu siqu njengezimonyo, insipho, ama-shampoo, ama-lotion, i-mouthwash, kanye ne-toothpaste. Izakhiwo ze-hygroscopic ze-Glycerol zenza kube umswakama omuhle emikhiqizweni yesikhumba. Okunye u-25% womkhiqizo waminyaka yonke we-glycerol usetshenziswa ekukhiqizweni kokudla. Embonini yokudla i-glycerol isetshenziswa njenge-ejenti yokuthambisa, njengesithako sokufaka umbala ekudleni kanye nama-syrups, ukuvimbela ukwakheka kweshukela kumaswidi kanye nama-icing, njengesivikelo, kanye ne-ejenti yokuthambisa. Cishe u-10% wokusetshenziswa kwe-glycerol uya ekucutshungulweni kukagwayi, lapho ufafazwa khona emaqabungeni kagwayi ngaphambi kokuba anqunywe ukuze asebenze njenge-ejenti yokuthambisa. I-Glycerol inenzuzo eyengeziwe yokunikeza ukunambitheka okumnandi kugwayi ohlafunwayo. Ama-25% asele okusetshenziswa kwe-glycerol asatshalaliswa phakathi kokusetshenziswa okuhlukahlukene kwezimboni. Isetshenziswa kuma-syrups okukhwehlela kanye nemithi ye-elixir. Ezimbonini, i-glycerol itholakala ezintweni zokugcoba, kuma-plasticizer, kuma-adhesive, kuma-antifreeze, kuma-resin, kanye nama-foam okuvikela umswakama. Ngesinye isikhathi yayisetshenziswa cishe kuphela ngesimo sayo se-nitrate njengesiqhumisi (bheka i-Nitroglycerin), namuhla equkethe cishe ama-3% okusetshenziswa kwayo.
I-Glycerol iyi-humectant esetshenziswa kuma-moisturizer. Ibopha amanzi futhi iyakwazi ukudonsa nokumunca amanzi emoyeni, ngaleyo ndlela isize isikhumba ukugcina umswakama. I-glycerin ihlolwe kabanzi ngamakhono ayo okugcina umswakama. Ngokusekelwe kudatha etholakalayo, i-glycerin isungulwe njenge-ejenti enhle yokufumisa isikhumba. Okungenani ingxenye yomsebenzi wayo ibangelwa ukuthi ikhuthaza ukusabela kwama-enzyme esikhumbeni, ngaleyo ndlela ikhuthaze ukususwa kwe-corneocyte. I-glycerin iphinde ithuthukise izimfanelo zokusabalala kwama-creams nama-lotion. Iwuketshezi olucacile, olune-syrup olwenziwe ngokuhlanganisa amanzi namafutha ngamakhemikhali ngokuvamile atholakala ku-oyela wemifino. Nakuba i-glycerin ingazange ibonakale ibangela ukungezwani komzimba, ingaba yi-comedogenic futhi icasule ulwelwesi lwama-mucous uma isetshenziswa ezixazululweni ezihlanganisiwe.
I-Glycerol isetshenziswa kokubili ekulungiseleleni amasampula kanye nokwakheka kwejeli ye-polyacrylamide gel electrophoresis. I-Glycerol (5-10%) yandisa ubuningi besampula ukuze isampula ibe ungqimba phansi komthombo wejeli. I-Glycerol isetshenziselwa futhi ukusiza ekubunjweni kwamajeli e-gradient kanye nanjenge-protein stabilizer kanye ne-storage buffer component.
Njenge-solvent, i-humectant, i-plasticizer, i-emollient, i-sweetener, ekukhiqizweni kwe-nitroglycerol (i-dynamite), izimonyo, insipho ewuketshezi, ama-liqueur, ama-confectioneries, i-blacking, i-printing and copying inks, ama-lubricants, ama-elastic glues, ama-lead oxide cements; ukugcina izindwangu zithambile; ukugcina ukuphrinta kukotini; kokuphrinta ama-roller, ama-hectograph; ukugcina iqhwa lingangeni ezibukweni zangaphambili; njenge-antifreeze ezimotweni, amamitha egesi kanye nama-hydraulic jacks, ku-shock absorber fluids. Ekuzalweni kokubilisa ekukhiqizweni kwama-antibiotic. Usizo lwemithi (i-humectant; i-solvent, imoto). ULeffingwell noLesser (op. cit.) banikeza ukusetshenziswa okuhlukile okungu-1583.
