I-1,3-Propanediol (ebizwa ngokuba yiPropanediol emva koku), isetyenziswa kakhulu njengesinyibilikisi. Ingalungisa amaxolo oboya obonakeleyo kwiimveliso zokhathalelo lweenwele, yenze iinwele zibe bushelelezi ngakumbi. Ithintela ukurhawuzelelwa kweenwele, yongeza i-5%. Ikwasetyenziswa njengearhente yokulawula ukurhawuzelelwa. I-1,3-Propanediol ecocekileyo ine-pH ekufutshane ne-7 kwaye nokuba kumanqanaba aphezulu kune-70% akukho kurhawuzelelwa kwesikhumba okanye ukuvakalelwa.
I-Propanediol yonyusa ukufuma xa isetyenziswa kwiimveliso zeenwele nomzimba, kwaye kwi-5%, isebenza ngcono kune-Propylene glycol kunye ne-Butylene glycol. Xa idityaniswe ne-Glycerin, i-Propanediol ibonisa isiphumo sokusebenzisana esinciphisa ukunamathela kwe-Glycerin, ngelixa inikezela ngeenzuzo zokunyuka kwamanqanaba okufuma. Kumanqanaba afikelela kwi-75%, ibonisa amandla aphantsi okucaphukisa okanye ukuchukumisa ulusu.
I-1,3-Propanediol (ebizwa ngokuba yiPropanediol emva koku) inokunyusa ukusebenza kwezigcini. I-Propanediol ayithathwa njengesigcini ngokwayo, kodwa inokusebenza njengesincedisi kwiinkqubo ezininzi zezigcini. I-Propanediol sisixhobo esisebenzayo ngakumbi kwiifomyula ezisekwe kwiPhenoxyethanol ngokuchasene neebhaktheriya (zombini i-gram positive ne-negative) kunye ne-yeast. Ukusetyenziswa kwePropanediol kunokunciphisa kakhulu inani lezigcini ezifunekayo kwifomyula.
