1,3-Propanediol (raug xa mus rau propanediol tom qab no), tsuas yog siv los ua cov kuab tshuaj. Nws tuaj yeem kho cov ntaub plaub tawm hauv cov khoom tu plaub hau, ua plaub hau kom du. Tiv thaiv cov plaub hau muaj kev chim siab, ntxiv 5%. Kuj tseem siv ua viscosity tswj tus neeg sawv cev. Ntshiab 1,3-Propanediol muaj qhov thib rau 7 thiab txawm tias muaj siab dua 70% muaj tsis muaj daim tawv nqaij lossis tsis zoo.
Propanediol nce hydration thaum siv nyob rau hauv cov plaub hau thiab cov khoom siv lub cev, thiab ntawm 5%, ua tau zoo dua li propylene glycole glycol. Thaum ua ke nrog glycerin, propanediol qhia tau cov nyhuv synergistic uas txo cov txiaj ntsig ntawm glycerin, thaum muab cov txiaj ntsig ntawm kev nce qib ntawm kev haus dej. Nyob rau theem nce txog 75%, nws qhia tau cov peev xwm tsawg los ua kom tawv nqaij lossis cov tawv nqaij.
1,3-Propanediol (raug xa mus rau propanediol heragter) tej zaum yuav txhawb txoj kev ua tau zoo ntawm cov tshuaj txuag hluav taws xob. Propanediol tsis suav hais tias yog cov tshuaj tiv thaiv nws tus kheej, tab sis tuaj yeem ua raws li koob tshuaj tiv thaiv hauv ntau cov tshuab hluav taws xob. Propanediol yog ib qho kev siv hluav taws xob ua tau zoo hauv phenoxyethanol raws cov qauv tawm tsam cov kab mob tiv thaiv kab mob (ob qho tib si gram zoo thiab cov poov xab) thiab cov poov xab. Kev siv ntawm Propanediol tuaj yeem txo cov nyiaj uas xav tau hauv cov qauv.
