1,3-Propanediol (inozivikanwa sePropanediol kubva pano), inonyanya kushandiswa semushonga wekugadzirisa bvudzi. Inogona kugadzirisa makwande emvere akakuvara muzvigadzirwa zvekuchengetedza bvudzi, kuita kuti bvudzi rive rakatsetseka. Dzivirira bvudzi kuti risanyanye kutsamwisa, wedzera 5%. Inoshandiswawo semushonga wekudzivirira kutsvuka kweganda. 1,3-Propanediol yakachena ine pH iri pedyo ne7 uye kunyangwe pahuwandu hwakakwira kupfuura 70% hapana kutsamwisa kweganda kana kunzwa.
Propanediol inowedzera kunyorova kana ikashandiswa muzvigadzirwa zvebvudzi nemuviri, uye pa5%, inoshanda zviri nani pane Propylene glycol neButylene glycol. Kana ikasanganiswa neGlycerin, Propanediol inoratidza simba rekubatsirana rinoderedza kunyorova kweGlycerin, ukuwo ichipa mabhenefiti ekuwedzera kwemvura. Pamazinga anosvika 75%, inoratidza mukana mudiki wekutsamwisa kana kunzwa ganda.
1,3-Propanediol (inozivikanwa sePropanediol kubva zvino) inogona kuwedzera kushanda kwemishonga yekuchengetedza. Propanediol haionekwi semushonga wekuchengetedza, asi inogona kushanda semushonga wekuchengetedza mune akawanda masisitimu ekuchengetedza. Propanediol imushonga unoshanda zvakanyanya mumishonga yakavakirwa paPhenoxyethanol kurwisa mabhakitiriya (ese ari maviri gram positive ne negative) uye mbiriso. Kushandiswa kwePropanediol kunogona kuderedza zvakanyanya huwandu hwemishonga yekuchengetedza inodiwa mumishonga iyi.
