1,3-Propanediol (hu ua Propanediol hereafter), feem ntau yog siv los ua cov kuab tshuaj.Nws tuaj yeem kho cov plaub hau puas hauv cov khoom tu plaub hau, ua kom cov plaub hau du.Tiv thaiv cov plaub hau khaus, ntxiv 5%.Kuj tseem siv los ua tus neeg saib xyuas viscosity.Ntshiab 1,3-Propanediol muaj pH ze rau 7 thiab txawm tias nyob rau hauv ntau dua 70% tsis muaj tawv nqaij khaus lossis rhiab heev.
Propanediol nce hydration thaum siv cov plaub hau thiab lub cev cov khoom, thiab ntawm 5%, ua tau zoo dua Propylene glycol thiab Butylene glycol.Thaum ua ke nrog Glycerin, Propanediol qhia tau hais tias muaj kev sib koom ua ke uas txo cov tackiness ntawm Glycerin, thaum muab cov txiaj ntsig ntawm cov dej ntau ntxiv.Ntawm qib mus txog 75%, nws qhia tau tias tsis tshua muaj peev xwm ua rau khaus lossis ua rau tawv nqaij.
1,3-Propanediol (hu ua Propanediol hereafter) tuaj yeem txhawb kev ua haujlwm ntawm cov tshuaj tua kab mob.Propanediol tsis yog suav tias yog ib qho tshuaj tiv thaiv nws tus kheej, tab sis tuaj yeem ua raws li kev txhawb nqa hauv ntau lub tshuab khaws cia.Propanediol yog ib qho kev txhawb zog tshwj xeeb hauv Phenoxyethanol raws li cov tshuaj tiv thaiv kab mob (ob qho tib si gram zoo thiab tsis zoo) thiab cov poov xab.Kev siv ntawm Propanediol tuaj yeem txo qis ntau ntawm cov khoom noj uas xav tau hauv kev tsim.
