Fa'amatalaga o oloa
E gaosia i luga o se fua tele mo le gaosiga o polymers. I le Iuni a Europa, o loʻo i ai le E-numera E1520 mo meaʻai. Mo cosmetics ma pharmacology, o le numera o le E490. O lo'o iai fo'i le propylene glycol i le propylene glycol alginate, lea e ta'ua o le E405. O le propylene glycol o se tuufaatasiga lea e GRAS (e masani ona iloa e saogalemu) e le US Food and Drug Administration i lalo ole 21 CFR x184.1666, ma ua faʻatagaina foi e le FDA mo nisi faʻaoga e avea o se meaʻai faʻaopoopo. O le propylene glycol ua fa'amaonia ma fa'aaogaina e fai ma ta'avale mo le fa'aogaina o le toto, tautala, ma nisi o vaila'au fa'amalositino i totonu o Amerika ma Europa.

Fa'atatauga
| E masani ona faʻaaogaina e avea o se faʻaopoopoga i fanua o vali, faʻapipiʻi ma faʻapipiʻi e faʻaleleia ai le susulu ma le mautu o le ufiufi. E mafai foi ona faʻaaogaina e avea o se solvent ma emulsifier i le gaosiga o mea faʻamama, vali vali ma vali. |
I vailaʻau faʻapitoa, MEA e faʻaaoga muamua mo le faʻafefe poʻo le saunia o faʻamaʻi. E mafai ona fa'aogaina le MEA e fai ma fa'atonu pH i mea teuteu.
O se sclerosant injectable e fai ma togafitiga o fa'ama'i ma'i toto. 2-5 ml ole ethanolamine oleate e mafai ona tui ile mucosa i luga a'e o le hemorrhoids e mafua ai le ma'i ma'i ma le mucosal fix ma taofia ai le alu ifo i fafo mai le anal canal.
Ose vaega fo'i e fa'amama ai le vai mo tioata o ta'avale.
Fa'amanuiaga
O le tuufaatasiga e taʻua i nisi taimi (alpha) α-propylene glycol e iloagofie ai mai le isomer propane-1,3-diol, ua taʻua o le (beta) β-propylene glycol. O le propylene glycol o le chiral. O faiga fa'apisinisi e masani ona fa'aogaina le racemate. O le S-isomer e gaosia e ala i biotechnological.
1,2-Propanediol o se mea taua tele mo polyester unsaturated, epoxy resin, polyurethane resin, plasticizer, ma surfactant. O le aofaʻi o loʻo faʻaaogaina i lenei vaega e tusa ma le 45% o le aofaʻi o le faʻaaogaina o le propylene glycol. E masani ona faʻaaogaina i luga o faʻaofuofu ma palasitika faʻamalosia. 1,2-propanediol o loʻo i ai le viscosity lelei ma le hygroscopicity, ma o loʻo faʻaaogaina lautele e pei o le hygroscopic agent, antifreeze agent, lubricant ma solvent i meaʻai, vailaʻau ma mea teuteu. I totonu o le fale gaosi meaʻai, 1,2-propanediol e faʻafefe ma gaʻo gaʻo e fausia ai le propylene glycol fatty acid esters, lea e masani ona faʻaaogaina e avea ma meaʻai emulsifiers; 1,2-propanediol o se soli sili ona lelei mo faʻamaʻi ma lanu. Ona o lona maualalo oona, e faʻaaogaina e avea o se solvent mo mea manogi ma lanu meaʻai i totonu o pisinisi taumafa. 1,,2-Propanediol e masani ona faʻaaogaina e avea o se solvent, softener ma le faʻaogaina i le gaosiga o suauu eseese ma suauu i totonu o le falemaʻi vailaʻau, ma o se solvent mo le faʻafefiloi o vailaʻau, faʻasao, suauu, vitamini, penicillin, ma isi mea i totonu o vailaʻau. alamanuia . Talu ai ona o le propylene glycol e lelei le faʻafefeteina ma mea manogi eseese, e faʻaaogaina foi e avea o se solvent ma le faʻamaluluina mo mea teuteu. 1,2-Propanediol o loʻo faʻaaogaina foi e avea o se tapaa moisturizer, antifungal agent, meaʻai gaosi meafaigaluega lubricant ma solvent mo meaʻai maka inks. O vaifofo vai o le 1,2-propanediol o ni vailaʻau faʻamaʻi lelei. E faʻaaogaina foʻi e fai ma sui susu tapaa, vailaʻau faʻamaʻi, faʻasao fualaʻau fualaʻau, faʻamaʻi ma vevela, ma isi.
