1,3-Propanediol (e tsejoang e le Propanediol ho tloha ka nako eo), e sebelisoa haholo-holo e le solvent. E ka lokisa makhakhapha a ulu a senyehileng lihlahisoa tsa tlhokomelo ea moriri, ea etsa hore moriri o be boreleli haholoanyane. Thibela moriri ho halefa, eketsa 5%. E boetse e sebelisoa e le sesebelisoa sa taolo ea viscosity. 1,3-Propanediol e hloekileng e na le pH e haufi le 7 'me esita le maemong a holimo ho 70% ha ho na ho halefa ha letlalo kapa ho utloa bohloko.
Propanediol e eketsa metsi ha e sebelisoa lihlahisoa tsa moriri le 'mele, 'me ka 5%, e sebetsa hantle ho feta Propylene glycol le Butylene glycol. Ha e kopantsoe le Glycerin, Propanediol e bontša phello ea tšebelisano-'moho e fokotsang ho tiea ha Glycerin, ha ka nako e ts'oanang e fana ka melemo ea maemo a eketsehileng a metsi. Maemong a fihlang ho 75%, e bontša bokhoni bo tlase ba ho halefisa kapa ho nyenyefatsa letlalo.
1,3-Propanediol (e tsejoang e le Propanediol ho tloha ka nako eo) e ka eketsa katleho ea li-preservative. Propanediol ha e nkoe e le se-preservative ka boeona, empa e ka sebetsa e le se-adjuster litsamaisong tse ngata tsa ho boloka. Propanediol ke se-adjuster se sebetsang hantle haholo-holo mefuteng e thehiloeng ho Phenoxyethanol khahlanong le libaktheria (tse nang le gram positive le negative) le tomoso. Tšebeliso ea Propanediol e ka fokotsa haholo palo ea li-preservative tse hlokahalang mofuteng.
