1,3-Propanediol (hu ua Propanediol tom qab no), feem ntau yog siv ua cov kuab tshuaj. Nws tuaj yeem kho cov plaub hau puas tsuaj hauv cov khoom saib xyuas plaub hau, ua rau plaub hau du dua. Tiv thaiv kom plaub hau tsis khaus, ntxiv 5%. Kuj siv ua tus neeg sawv cev tswj viscosity. 1,3-Propanediol ntshiab muaj pH ze li 7 thiab txawm tias ntawm cov concentration siab dua 70% tsis muaj kev khaus lossis sensitization ntawm daim tawv nqaij.
Propanediol ua rau cov dej noo ntau ntxiv thaum siv rau hauv cov khoom siv rau plaub hau thiab lub cev, thiab ntawm 5%, ua haujlwm zoo dua li Propylene glycol thiab Butylene glycol. Thaum ua ke nrog Glycerin, Propanediol qhia txog kev sib koom ua ke uas txo qhov tackiness ntawm Glycerin, thaum muab cov txiaj ntsig ntawm kev nce qib ntawm kev noo. Ntawm cov theem txog li 75%, nws qhia txog qhov tsis tshua muaj peev xwm ua rau khaus lossis ua rau tawv nqaij rhiab heev.
1,3-Propanediol (hu ua Propanediol tom qab no) yuav ua rau cov tshuaj preservatives ua haujlwm tau zoo dua. Propanediol tsis suav tias yog cov tshuaj preservative nws tus kheej, tab sis tuaj yeem ua haujlwm ua tus txhawb nqa hauv ntau lub tshuab preservative. Propanediol yog tus txhawb nqa zoo tshwj xeeb tshaj yog hauv Phenoxyethanol raws li cov qauv tsim tawm tsam cov kab mob (ob qho tib si gram positive thiab negative) thiab cov poov xab. Kev siv Propanediol tuaj yeem txo qhov ntau ntawm cov tshuaj preservatives uas xav tau hauv cov qauv.
