I-Propylene glycol iwuketshezi olungenambala, olungenaphunga, oluqinile kancane olunokwakheka okujiyile kancane kunamanzi. Ayinambitheki cishe futhi iyisithako sokudla esenziwe ngamakhemikhali. Njenge-ethanol, iyinto edakayo.

Ngaphezu kwalokho, njenge-organic solvent, ingancibilikisa ezinye izinto eziphilayo ezincibilikayo kangcono kunamanzi futhi ingagcina nomswakama kahle. Ngenxa yalezi zakhiwo zamakhemikhali ezikhethekile, isetshenziswa kabanzi ezimonyweni. I-Propylene glycol ingasetshenziswa njenge-moisturizer, i-softener, i-solvent, njll., futhi inemiphumela emihle kakhulu yokuthambisa nokusetshenziswa. Ingasetshenziswa cishe kuzo zonke izimonyo, ikakhulukazi amanzi, i-lotion, ukhilimu, i-facial mask neminye imikhiqizo.

Ngaphezu kwensimu yezimonyo, ibalulekile futhi emkhakheni wokudla. Iyasazi, kodwa asiyinaki kangako. Ngokusho kwe-“GB 2760-2014 National Food Safety Standard – Food Additive Usage Standard”, imisebenzi ye-propylene glycol yile: i-stabilizer, i-coagulant, i-anti-caking agent, i-defoaming agent, i-emulsifier, i-moisture retaining agent, kanye ne-thickener.

Ngakho-ke, ivame ukusetshenziswa njenge-emulsifier yokudla okufanele ifakwe esinkweni, ebhotela nakweminye imikhiqizo. Ngaphezu kwalokho, i-propylene glycol ivame ukusetshenziswa ezinqubweni zokucubungula nokukhipha ubhiya njengesinyibilikisi sezinto ezinephunga elimnandi.

Ngaphezu kwalokho, kubangani abathanda ukubhaka, i-propylene glycol iwumkhiqizo ovame ukusetshenziswa, ongasiza ama-pastry ukuthi athole ukunambitheka okungcono kanye nokunambitheka.

Ngokwezindinganiso zikazwelonke, ukudla okuphephile kwe-propylene glycol kulandela izindinganiso ezibekwe yi-International Joint Expert Group on Food Additives, okungukuthi, ukudla kwansuku zonke akufanele kudlule ama-25 mg ngekhilogramu yesisindo somzimba.

Kumuntu omdala onesisindo esingama-70 kg, ukudla okuphezulu kwansuku zonke akudluli ku-1.75 g. Njengamanje, emkhakheni wokukhiqizwa kokudla okuphekiwe njengamakhekhe, lapho kusetshenziswa i-propylene glycol njengesithako, indlela esetshenziswayo ngokuyisisekelo ukuthi okuqukethwe akudluli amagremu ama-3 ngekhilogramu ngayinye yokudla.

I-Propylene glycol ingavunyelwa ukusetshenziswa njengesithasiselo sokudla futhi idlule ekuhlolweni okuqinile kokuphepha. Ngaphansi "kwezimo zokusetshenziswa ezijwayelekile kanye nokudla", "ukusetshenziswa kwesikhathi eside" ngeke kube yingozi empilweni.
