O le propylene glycol e faʻaaogaina mo faʻaoga tutusa e pei o isi glycols.
O le propylene glycol ose mea taua tele mo polyester unsaturated, epoxy resin, ma polyurethane resin.Ole aofa'i ole fa'aoga ile vaega lea e tusa ma le 45% ole aofa'iga ole fa'aaogaina ole propylene glycol.O ia polyester unsaturated e faʻaaogaina tele mo palasitika faʻamalosia ma faʻapipiʻi luga.O le propylene glycol e sili ona lelei i le viscosity ma le hygroscopicity ma e le oona, ma o lea e faʻaaogaina lautele e pei o le hygroscopic agent, antifreeze, lubricants ma solvents i totonu o meaʻai, vailaʻau ma mea teuteu.I totonu o le alamanuia o mea'ai, e tali atu le propylene glycol ma le ga'o ga'o e tu'uina atu ai le propylene ester o ga'o ga'o, ma e masani ona fa'aaogaina e fai ma mea'ai emulsifier;O le propylene glycol o se vaifofo lelei mo mea manogi ma lanu.O le propylene glycol e masani ona faʻaaogaina e pei o solvents, softeners ma excipients, ma isi mea i totonu o fale gaosi oloa mo le gaosiga o ituaiga eseese o suauu ma salves.O le propylene glycol o loʻo faʻaaogaina foi e avea o se solvent ma se faʻamaluluina mo cosmetics talu ai e lelei le solubility ma mea manogi eseese.O le propylene glycol o loʻo faʻaaogaina foi e avea ma vailaʻau moisturizing tapaa, vailaʻau faʻamaʻi, mea e gaosia ai meaʻai lubricants ma solvents mo meaʻai maka vaitusi.Ole vaifofo vai ole propylene glycol ose vaila'au fa'ato'a fa'a'aisa lelei.
I tafatafa o le vai, o le propylene glycol o le taʻavale masani e ave ai le susu e faʻaaogaina i mea teuteu.E sili atu le pa'u o le pa'u nai lo le glycerin, ma e maua ai fo'i se lagona manaia e itiiti ifo le ga'o nai lo le glycerin.O le propylene glycol o lo'o fa'aaogaina e fai ma humectant aua e mitiia ai le vai mai le ea.E galue foi o se solvent mo anti-oxidants ma preservatives.E le gata i lea, o loʻo i ai mea faʻasao e faasaga i siama ma sigi pe a faʻaaogaina i faʻasalalauga o le 16 pasene pe sili atu.O lo'o iai le atugaluga o le propylene glycol ose mea e fa'aita i le maualuga, e ui lava e foliga mai e matua saogalemu pe a fa'aoga i lalo ole 5 pasene.
O le propylene Glycol ose mea e fa'amama ma fa'afefeteina le tofo o le polyhydric alcohol (polyol).o se vai manino, viscous ma atoatoa solu- i le vai i le 20°c ma solvency lelei suauu.e galue e pei o se humectant, e pei o le glycerol ma le sorbitol, i le faatumauina o le susū manaʻomia i totonu o meaʻai e pei o le niu tipi ma aisa.e galue o se solvent mo tofo ma lanu e le mafai ona solu i le vai.e fa'aaogaina fo'i i meainu ma lole.
