1,2-Propylene Glycol CAS NO.57-55-6
Fa'amatalaga o oloa
- 1,2 Propylene glycol o se vaeluaga o le bactericide difenoconazole ma se mea mata'utia taua mo polyester unsaturated, epoxy resin, ma polyurethane resin. O le aofaʻi i lenei vaega e tusa ma le 45% o le aofaʻi o le faʻaaogaina o le 1,2 propylene glycol. O lenei poly Ester e le'i tumu e fa'aaogaina lautele i fa'alavalava i luga ma palasitika fa'amalosia. 1,2 Propylene glycol o loʻo i ai le viscosity lelei ma le hygroscopicity, ma e le o se mea oona, o lea e masani ona faʻaaogaina e pei o se susu susu, antifreeze, lubricant ma solvent i meaʻai, vailaʻau ma fale gaosi oloa. I totonu o le alamanuia taumafa, e masani ona faʻaaogaina e avea o se meaʻai emulsifier; i le taimi lava e tasi o se solvent sili ona lelei mo faʻamaʻi ma pigments.
- O le faʻagasologa o le faʻaaogaina o le 1,2 propylene glycol e aʻafia i le matata faʻapitoa o le vavaeeseina o vailaʻau. O lenei faiga e fa'aogaina ai uiga e faigofie ona fa'ama'a'a'a'i ai masima minerale, a'o masima fa'aola o lo'o i totonu o le propylene glycol fermentation broth e le faigofie ona tioata. Ose aofaiga talafeagai ole acid inorganic e faaopoopo i le propylene glycol fermentation broth e sui ai masima acid organic i totonu ole sua fa'afefete i acids organic. Ole masima minerale tutusa e gaosia; o le sua fa'afefete e fa'atumauina, ina ia fa'ama'i ai le masima minerale, ma vavae'ese mai le sua fa'afefete; o le susu faʻafefete faʻamalosi e avea propylene glycol, succinic acid, lactic acid, acetic acid, glycerol ma le 2,3-butane O le faʻafefiloi o le ava malosi, faʻamama faʻafefeteina o le paluga e maua ai oloa o vaega taʻitasi. I le falema'i vaila'au, o le propylene glycol e masani ona fa'aaogaina e avea o se solvent, fa'amalulu ma fa'amalosi mo le gaosiga o suauu eseese ma suauu. Ona o lona fetaui lelei ma mea manogi eseese, e faʻaaogaina foi e avea o se solvent ma le faʻamaluluina mo cosmetics.Propylene glycol o loʻo faʻaaogaina foi e avea o se tapaa moisturizer, antifungal agent, mea gaosi meaʻai lubricating suauu ma meaʻai maka vaitusi solvent. O se vaifofo vai o le propylene glycol o se anti'aisa lelei.
