1,3-Propanediol (eo ho thoeng ke Propanediol ka morao ho mona), haholo-holo e sebelisoang e le solvent.E ka lokisa likala tsa boea tse senyehileng lihlahisoa tsa tlhokomelo ea moriri, ea etsa hore moriri o be boreleli haholoanyane.Thibela moriri o halefileng, eketsa 5%.E boetse e sebelisoa e le moemeli oa taolo ea viscosity.1,3-Propanediol e hloekileng e na le pH e haufi le 7 esita le maemong a holimo ho feta 70% ha ho na ho teneha ha letlalo kapa ho utloahala.
Propanediol e eketsa metsi ha e sebelisoa moriri le lihlahisoa tsa 'mele,' me ka 5%, e sebetsa hantle ho feta Propylene glycol le Butylene glycol.Ha e kopantsoe le Glycerin, Propanediol e bonts'a phello ea synergistic e fokotsang tackiness ea Glycerin, ha e ntse e fana ka melemo ea ho eketseha ha maemo a metsi.Ho maemo a fihlang ho 75%, e bonts'a monyetla o tlase oa ho halefisa kapa ho thoba letlalo.
1,3-Propanediol (e bitsoang Propanediol ka morao ho mona) e ka eketsa katleho ea li-preservatives.Propanediol ha e nkoe e le ntho e sireletsang ka boeona, empa e ka sebetsa e le matlafatso lits'ebetsong tse ngata tsa ho boloka.Propanediol ke booster e sebetsang hantle ka ho khetheha ho Phenoxyethanol e thehiloeng ho metsoako e khahlanong le libaktheria (bobeli ba gram-positive le negative) le tomoso.Tšebeliso ea Propanediol e ka fokotsa haholo palo ea li-preservative tse hlokahalang ha ho etsoa.
