I-1,3-Propanediol (ebizwa ngokuthi i-Propanediol kusukela manje), isetshenziswa kakhulu njengesithako sokuhlanza. Ingalungisa izikali zoboya ezonakele emikhiqizweni yokunakekelwa kwezinwele, yenze izinwele zibe bushelelezi kakhudlwana. Vimbela ukucasuka kwezinwele, engeza u-5%. Isetshenziswa futhi njenge-ejenti yokulawula i-viscosity. I-1,3-Propanediol emsulwa ine-pH eseduze no-7 futhi ngisho noma amazinga aphezulu kuno-70% akukho ukucasuka kwesikhumba noma ukuzwela.
I-Propanediol ikhulisa umswakama uma isetshenziswa emikhiqizweni yezinwele nomzimba, futhi ku-5%, isebenza kangcono kune-Propylene glycol kanye ne-Butylene glycol. Uma ihlanganiswa ne-Glycerin, i-Propanediol ikhombisa umphumela wokubambisana onciphisa ukuqina kwe-Glycerin, ngenkathi inikeza izinzuzo zamazinga aphezulu omswakama. Emazingeni afinyelela ku-75%, ikhombisa amandla aphansi okucasula noma ukuzwela isikhumba.
I-1,3-Propanediol (ebizwa ngokuthi i-Propanediol ngemuva kwalokhu) ingathuthukisa ukusebenza kahle kwezilondolozi. I-Propanediol ayibhekwa njengesilondolozi ngokwayo, kodwa ingasebenza njengesikhuthazi ezinhlelweni eziningi zokulondoloza. I-Propanediol iyisikhulisi esisebenzayo ikakhulukazi ekwakhiweni okusekelwe ku-Phenoxyethanol ngokumelene namagciwane (kokubili i-gram positive ne-negative) kanye nemvubelo. Ukusetshenziswa kwe-Propanediol kunganciphisa kakhulu inani lezilondolozi ezidingekayo ekwakhiweni.
