1, {{2-} {propanediol yog ib qho tseem ceeb organic sib txuas nrog kev siv hauv ntau thaj teb:
- Kev lag luam khoom noj: Propylene glycol muaj cov khoom siv solubility zoo thiab tuaj yeem siv los ua cov kuab tshuaj ntxiv los txhim kho cov tsos thiab qab ntawm cov zaub mov; Nws tuaj yeem nqus noo noo hauv huab cua, tiv thaiv cov zaub mov los ntawm ziab, thiab txuas rau lub neej ntawm cov khoom noj; Nws tuaj yeem txo cov dej khov thiab muab ntxiv rau qee cov zaub mov khov kom tiv thaiv cov txheej txheem dej khov ntau dhau thaum lub sijhawm khov thiab saj ntawm cov zaub mov.
- Kws Tshuaj Kev Lag Luam: Ntau ntau cov khoom xyaw siv tshuaj muaj ntau muaj solubility tsis zoo hauv dej. Propylene Glycol tuaj yeem siv los ua cov kuab tshuaj los pab yaj tshuaj thiab ua rau muaj ntau cov ntawv ntau npaum li cas; Hauv qee cov ntsiab lus npaj, 1, 2-}}} {propanediol tuaj yeem tiv thaiv cov kev npaj los ntawm kev ziab. Nws tseem muaj qee cov nyhuv tiv thaiv kab mob, uas pab txhawb kom ntev lub txee lub neej ntawm cov yeeb tshuaj; PG tuaj yeem nce cov khoom siv ntawm daim tawv nqaij, txhawb kev nqus tshuaj los ntawm daim tawv nqaij, thiab txhim kho cov tshuaj.
- Cov tshuaj pleev ib ce kev lag luam: pg yog ib qho ntawm cov moisturizing cov khoom xyaw hauv cov tshuaj pleev ib ce. Nws tuaj yeem tsim cov yeeb yaj kiab moisturizing ntawm daim tawv nqaij kom tiv thaiv kom tsis txhob muaj dej poob thiab ua kom daim tawv nqaij noo thiab du. Nws yog siv los yaj cov khoom xyaw roj roj hauv cov tshuaj pleev ib ce, xws li cov vitamins, cog cov tshuaj ntawm cov tshuaj pleev ib ce ntau ruaj khov thiab hnav khaub ncaws. Hauv qee cov tshuaj pleev ib ce siv hauv qhov chaw tsawg-ib puag ncig, nws tuaj yeem siv los ua cov tshuaj tiv thaiv kom tiv thaiv cov khoom lag luam los ntawm khov thiab ua kom khov.
- Muaj cov teb: pg yog ib qho tseem ceeb raw rau kev tsim cov khoom siv polymer xws li polyester resin, polyether cob, thiab polyurethane. Cov tshuaj aqueous ntawm 1, 2-}}}}}}}}}}}}}}}}}}}}}}} }ol muaj cov tshuaj tiv thaiv zoo thiab tuaj yeem siv rau hauv cov tsheb txias thiab cov nkoj. Vim tias nws muaj lub siab npau npau thiab muaj tshuaj lom neeg khov kho, nws tuaj yeem siv tau los hloov cov cua sov hauv qee cov txheej txheem uas yuav tsum tau tswj qhov kub thiab txias.
