I-Propylene glycol lulwelo olungenambala, olungenavumba, olunencasa encinci olunobume obutyebileyo kunamanzi. Ayinancasa kangako kwaye sisongezelelo sokutya esenziwe ngeekhemikhali. Njenge-ethanol, sisithako esinxilisayo.

Ukongeza, njengesinyibilikisi sendalo, sinokunyibilikisa ezinye izinyibilikisi zendalo ngcono kunamanzi kwaye sinokugcina umswakama kakuhle. Ngenxa yezi mpawu zikhethekileyo zeekhemikhali, isetyenziswa kakhulu kwizithambiso. I-Propylene glycol ingasetyenziswa njenge-moisturizer, i-softener, i-solvent, njl.njl., kwaye inefuthe elihle kakhulu lokuthambisa kunye nokusetyenziswa. Ingasetyenziswa phantse kuzo zonke izithambiso, ngakumbi amanzi, i-lotion, i-cream, i-facial mask kunye nezinye iimveliso.

Ukongeza kwicandelo lezinto zokuthambisa, ikwabalulekile kwicandelo lokutya. Iyayazi, kodwa asiyikhathaleli kangako. Ngokwe-“GB 2760-2014 National Food Safety Standard – Food Additive Usage Standard”, imisebenzi yepropylene glycol yile: i-stabilizer, i-coagulant, i-anti-caking agent, i-defoaming agent, i-emulsifier, i-moisture retaining agent, kunye ne-thickener.

Kungoko ke, isetyenziswa njenge-emulsifier yokutya ukuze yongezwe kwisonka, ibhotolo kunye nezinye iimveliso. Ukongeza, i-propylene glycol isetyenziswa rhoqo kwiinkqubo zokucubungula nokukhupha ibhiya njengesinyibilikisi sezinto ezinevumba elimnandi.

Ukongeza, kubahlobo abathanda ukubhaka, ipropylene glycol yimveliso esetyenziswa kakhulu, enokunceda iipastries zifumane incasa engcono kunye nencasa.

Ngokwemigangatho yesizwe, ukutya okukhuselekileyo kwepropylene glycol kulandela imigangatho ebekwe yi-International Joint Expert Group on Food Additives, oko kukuthi, ukutya kwemihla ngemihla akufanele kudlule kwi-25 mg ngekhilogram nganye yobunzima bomzimba.

Kumntu omdala obunzima buyi-70 kg, ubuninzi bokutya okudliwayo ngemini abudluli kwi-1.75 g. Okwangoku, kwicandelo lokuveliswa kokutya okuphekiweyo okufana neekhekhe, xa kusetyenziswa i-propylene glycol njengesongezelelo, indlela eyamkelweyo kukuba umxholo ungadluli kwi-3 grams ngekhilogram yokutya.

I-Propylene glycol ingavunyelwa ukuba isetyenziswe njengesongezelelo sokutya kwaye iphumelele uvavanyo oluqinileyo lokhuseleko. Phantsi "kweemeko zokusetyenziswa kunye nokuthathwa okuqhelekileyo", "ukusetyenziswa ixesha elide" akuyi kuba yingozi empilweni.
