1,3-Propanediol (yomwe imatchedwanso Propanediol pambuyo pake), imagwiritsidwa ntchito makamaka ngati chosungunulira. Imatha kukonza mamba a ubweya omwe awonongeka muzinthu zosamalira tsitsi, kupangitsa tsitsi kukhala losalala. Kuletsa tsitsi kusakwiya, kuwonjezera 5%. Imagwiritsidwanso ntchito ngati chowongolera kukhuthala. 1,3-Propanediol yoyera ili ndi pH yoyandikira 7 ndipo ngakhale pamlingo woposa 70% palibe kuyabwa pakhungu kapena kukhudzidwa.
Propanediol imawonjezera madzi akagwiritsidwa ntchito mu zinthu za tsitsi ndi thupi, ndipo pa 5%, imagwira ntchito bwino kuposa Propylene glycol ndi Butylene glycol. Ikaphatikizidwa ndi Glycerin, Propanediol imawonetsa mphamvu yogwirizana yomwe imachepetsa kuuma kwa Glycerin, pomwe imapereka ubwino wowonjezera madzi. Pamlingo wofika 75%, imasonyeza kuthekera kochepa kokwiyitsa kapena kupangitsa khungu kukhala lolimba.
1,3-Propanediol (yomwe imatchedwa Propanediol pambuyo pake) ingalimbikitse mphamvu ya zosungira. Propanediol siiganiziridwa ngati chosungira chokha, koma imagwira ntchito ngati chowonjezera m'machitidwe ambiri osungira. Propanediol ndi chowonjezera chogwira ntchito makamaka mu mapangidwe opangidwa ndi Phenoxyethanol motsutsana ndi mabakiteriya (onse gram positive ndi negative) ndi yisiti. Kugwiritsa ntchito Propanediol kungachepetse kwambiri kuchuluka kwa zosungira zomwe zimafunikira mu kapangidwe kake.
