O le propylene glycol o se vai e leai se lanu, e leai se manogi, e fai si viscous ma lona tino e sili atu le mafiafia nai lo le vai. E toetoe lava a leai se tofo ma ose mea'ai fa'apipi'i fa'a kemikolo. E pei o le ethanol, o se mea inu ava malosi.

E le gata i lea, i le avea ai o se solvent organic, e mafai ona faʻamavaeina nisi solutes organic sili atu nai lo le vai ma mafai foi ona taofi lelei le susu. Ona o nei vailaʻau faʻapitoa, e faʻaaogaina lautele i mea teuteu. O le propylene glycol e masani lava ona faʻaaogaina e avea o se faʻasusu, faʻamaluluina, solvent, ma isi mea, ma e sili ona lelei le susu ma le faʻaogaina o aʻafiaga. E mafai ona faʻaaogaina i toetoe lava o mea teuteu uma, aemaise lava vai, lotion, kulimi, ufimata mata ma isi oloa.

I le faaopoopo atu i le fanua cosmetics, e taua foi i le fanua meaai. Na te silafia i tatou, ae tatou te le ano i ai. E tusa ai ma le "GB 2760-2014 National Food Safety Standard - Food Additive Usage Standard", o galuega a le propylene glycol o: stabilizer, coagulant, anti-caking agent, defoaming agent, emulsifier, moisture retaining agent, ma mafiafia.

O le mea lea, e masani ona faʻaaogaina o se meaʻai emulsifier e faʻaopoopo i falaoa, pata ma isi oloa. E le gata i lea, o le propylene glycol e masani ona faʻaaogaina i le gaosiga o pia ma faʻagasologa o le faʻaaogaina e avea o se solvent mo mea manogi.

E le gata i lea, mo uo e fiafia e tao, o le propylene glycol o se mea e masani ona faʻaaogaina, lea e mafai ona fesoasoani i pastries e maua ai se tofo sili atu ma le tofo.

E tusa ai ma tulaga faʻale-atunuu, o le saogalemu o le faʻaogaina o le propylene glycol e mulimulitaʻia tulaga faʻatulagaina e le International Joint Expert Group on Food Additives, o lona uiga, o le taumafa i aso uma e le tatau ona sili atu i le 25 mg i le kilokalama o le mamafa o le tino.

Mo se tagata matua e mamafa 70 kilokalama, o le maualuga o le taumafa i aso taitasi e le sili atu i le 1.75 g. I le taimi nei, i le tulaga o le gaosiga o meaʻai e pei o keke, pe a faʻaaogaina le propylene glycol e fai ma faʻaopoopoga, o le auala e faʻaaogaina e le sili atu i le 3 kalama i le kilokalama o meaʻai.

E mafai ona fa'amaonia le propylene glycol mo le fa'aogaina e fai ma mea'ai fa'aopoopo ma ua pasia su'esu'ega mo le saogalemu. I lalo o "fa'ata'ita'iga fa'aoga masani ma mea'ai", "fa'aumi umi" o le a le afaina ai le soifua maloloina.
