1,3-Propanediol (yotchedwa Propanediol pambuyo pake), yomwe imagwiritsidwa ntchito makamaka ngati zosungunulira.Ikhoza kukonza mamba a ubweya wowonongeka muzinthu zosamalira tsitsi, kupangitsa tsitsi kukhala losalala.Pewani kukwiyitsa tsitsi, onjezerani 5%.Amagwiritsidwanso ntchito ngati viscosity control agent.1,3-Propanediol yoyera imakhala ndi pH pafupi ndi 7 ndipo ngakhale pamiyeso yoposa 70% palibe kupsa mtima kapena kulimbikitsa khungu.
Propanediol imawonjezera hydration ikagwiritsidwa ntchito muzogulitsa tsitsi ndi thupi, ndipo pa 5%, imachita bwino kuposa Propylene glycol ndi Butylene glycol.Pophatikizana ndi Glycerin, Propanediol imawonetsa mphamvu ya synergistic yomwe imachepetsa mphamvu ya Glycerin, pomwe ikupereka phindu la kuchuluka kwa hydration.Pamilingo yofikira 75%, imawonetsa kuthekera kocheperako kukwiyitsa kapena kutsitsimutsa khungu.
1,3-Propanediol (yotchedwa Propanediol pambuyo pake) ikhoza kulimbikitsa mphamvu zotetezera.Propanediol sichimatengedwa ngati chosungira chokha, koma imatha kukhala ngati chilimbikitso m'machitidwe ambiri oteteza.Propanediol ndiwowonjezera bwino kwambiri mu Phenoxyethanol based formulations motsutsana ndi mabakiteriya (onse gram positive ndi negative) ndi yisiti.Kugwiritsiridwa ntchito kwa Propanediol kungachepetse kwambiri kuchuluka kwa zosungira zofunika pakupanga.
