I-1,3-Propanediol (okubhekiselwa kuyo njenge-Propanediol kamuva), esetshenziswa ikakhulukazi njengesixazululi.Ingakwazi ukulungisa izikali zoboya ezilimele emikhiqizweni yokunakekelwa kwezinwele, yenze izinwele zibe bushelelezi.Vimbela izinwele ezicasulayo, engeza u-5%.Ibuye isetshenziswe njenge-ejenti yokulawula i-viscosity.I-1,3-Propanediol ehlanzekile ine-pH esondele ku-7 futhi ngisho nasezindaweni zokugxila ezingaphezulu kuka-70% akukho ukucasuka kwesikhumba noma ukuzwela.
I-Propanediol yandisa uketshezi lapho isetshenziswa ezinweleni nasemikhiqizweni yomzimba, futhi ku-5%, yenza kangcono kune-Propylene glycol ne-Butylene glycol.Lapho ihlanganiswa ne-Glycerin, i-Propanediol ikhombisa umphumela we-synergistic onciphisa ukuqina kwe-Glycerin, ngenkathi inikeza izinzuzo zamazinga anyusiwe we-hydration.Emazingeni afika ku-75%, kukhombisa amandla aphansi okucasula noma ukuqwashisa isikhumba.
I-1,3-Propanediol (okubhekiselwa kuyo njenge-Propanediol ngemuva kwalokhu) ingase ikhulise ukusebenza kahle kwezilondolozi.I-Propanediol ayibhekwa njengesilondolozi ngokwayo, kodwa ingasebenza njenge-booster ezinhlelweni eziningi zokulondoloza.I-Propanediol iyi-booster esebenzayo ikakhulukazi ekwenziweni okusekelwe kwe-Phenoxyethanol ngokumelene namagciwane (kokubili i-gram-positive ne-negative) kanye nemvubelo.Ukusetshenziswa kwePropanediol kunganciphisa ngokuphawulekayo inani lezilondolozi ezidingekayo ekubunjweni.
