| 1,3-Propanediol | 504-63-2 | C3H8O2 | 76.10 |
1,3-Propanediol (byitwa Propanediol nyuma), ikoreshwa cyane cyane.Irashobora gusana umunzani wangiritse mubicuruzwa byita kumisatsi, gukora umusatsi neza.Irinde umusatsi kurakara, ongeramo 5%.Ikoreshwa kandi nka agent igenzura.Pure 1,3-Propanediol ifite pH hafi ya 7 ndetse no mubitekerezo birenga 70% nta kurakara kuruhu cyangwa gukangurira.
Propanediol yongerera amazi iyo ikoreshejwe mumisatsi nibicuruzwa byumubiri, kandi kuri 5%, ikora neza kurusha Propylene glycol na Butylene glycol.Iyo uhujwe na Glycerine, Propanediol yerekana ingaruka zoguhuza zigabanya ubukana bwa Glycerine, mugihe zitanga inyungu zo kwiyongera kwamazi.Kurwego rugera kuri 75%, rwerekana ubushobozi buke bwo kurakaza cyangwa gukangurira uruhu.
1,3-Propanediol (byitwa Propanediol nyuma) irashobora kongera imbaraga zo kubungabunga ibidukikije.Propanediol ntabwo ifatwa nkuburinzi ubwayo, ariko irashobora gukora nka sisitemu yo kubungabunga ibintu byinshi.Propanediol niyongera cyane cyane muri Phenoxyethanol ishingiye kuri bagiteri (garama nziza nibibi) hamwe numusemburo.Gukoresha Propanediol birashobora kugabanya cyane umubare wibintu bikenerwa mukubikora.
