I-Propylene glycol, eyaziwa ngokuba yi-IUPAC i-propane-1,2-diol, i-viscous, ulwelo olungenambala kunye nencasa eswiti ngokungakhathali. Ngokwemichiza, yi-CH3CH(OH)CH2OH. Ipropylene glycol, enamaqela amabini otywala, isetyenziswe kwiindidi ezahlukeneyo zamashishini. Ihlala isetyenziswa njengenyibilikisi, isithako sokutya, nasekuveliseni iikhompawundi ezininzi.
Ipropylene glycol isetyenziswa kakhulu kwishishini lokutya. Ngenxa yesakhono sayo sokuthintela ukukhula kweentsholongwane kunye nokungunda, isetyenziswa ngokuqhelekileyo njengento egcina ukutya. Ukutya kugcinwa kumanzi kusetyenziswa ipropylene glycol, esebenza njenge-humectant ukubamba emanzini. Ngenxa yolu phawu, ipropylene glycol yongezelela esetyenziswa ngokubanzi kwiintlobo ezahlukeneyo zokutya okucutshungulwayo, kubandakanywa ukuxuba ikhekhe kunye nokugqoka isaladi. Njenge-emulsifier, isetyenziswa rhoqo ukuqinisekisa ukuba amanzi kunye neoli zidibanisa ngokufanayo kwiintlobo ezahlukeneyo zeempahla.
Esinye isicelo sepropylene glycol kukwenziwa kweekhompawundi ezahlukeneyo. Ipropylene glycol isetyenziswa njengesipholisi kwiinkqubo zoshishino, enye yezona zinto zibalulekileyo zokusetyenziswa. Kumashishini amaninzi, ukupholisa kuyafuneka ukuze kugcinwe izixhobo ezishushu kakhulu okanye zingaphumi. Ipropylene glycol ikwasetyenziswa njengenjini yokupholisa iimoto. Ukongeza, ukuveliswa kwezinto zokuncamathelisa, iipeyinti, kunye namafutha ezithuthi zisebenzisa rhoqo ipropylene glycol.
Ipropylene glycol iyagqwesa kwizinto ezigqobhozayo njengesinyibilikisi. Iluncedo kakhulu kwiinkqubo zeshishini kunye nemveliso ngenxa yolu phawu. Ukongeza kokusetyenziswa njenge-solvent yokunyibilikisa i-insecticide kunye ne-herbicides ngaphambi kokusetyenziswa, i-propylene glycol iphinda isetyenziswe ekukhutshweni kwe-flavour yendalo okanye yokwenziwa.
Nangona kunjalo, ukusebenzisa ipropylene glycol kuthwala iingozi ezithile zempilo, njengokusebenzisa nayiphi na imichiza, ngoko ke kubalulekile ukusebenzisa izilumkiso zokhuseleko ngamaxesha onke. Ukusela kunokubangela isicaphucaphu kunye nesiyezi, ngelixa ukudibana ngokuthe ngqo kwesikhumba kunokucaphukisa ulusu. Nangona kunjalo, xa isetyenziswe ngokuchanekileyo kunye nezixa ezifanelekileyo, iinkxalabo zempilo yepropylene glycol zincinci.
Isishwankathelo, ipropylene glycol yimolekyuli yeekhemikhali ezixabisekileyo ezinoluhlu olubanzi lwezicelo kumacandelo ahlukeneyo. Iimpawu ezahlukileyo zePropylene glycol zenza kube lukhetho oluhle kakhulu kwizicelo ezininzi, kubandakanya ukuveliswa kokutya, ukwenziwa kweekhemikhali, iimoto kunye nokusetyenziswa kwemizi-mveliso ngokubanzi. Ipropylene glycol kufuneka iphathwe ngokucophelela, njengazo zonke iikhemikhali, kodwa xa yenziwe, ingaba yinto esebenzayo kunye neyobuchule kumacandelo ahlukeneyo.
