1,3-Propanediol (izwi nka Propanediol nyuma y'ibi), ikoreshwa cyane cyane nk'umuti. Ishobora gusana imiterere y'ubwoya yangiritse mu bikoresho byo kwita ku musatsi, bigatuma umusatsi urushaho kuba mwiza. Irinda umusatsi kurakara, wongereho 5%. Ikoreshwa kandi nk'umuti ugenzura ubushyuhe. 1,3-Propanediol nziza ifite pH hafi ya 7 kandi nubwo yaba iri hejuru ya 70% nta ruhu rubabara cyangwa ngo rugire ubukana.
Propanediol yongera ubushyuhe iyo ikoreshejwe mu musatsi no mu mubiri, kandi kuri 5%, ikora neza kurusha Propylene glycol na Butylene glycol. Iyo ihujwe na Glycerin, Propanediol igaragaza ingaruka nziza zigabanya ubushyuhe bwa Glycerin, mu gihe itanga inyungu zo kwiyongera k'ubushyuhe. Ku rugero rugera kuri 75%, igaragaza ubushobozi buke bwo gukangura cyangwa kuvura uruhu.
1,3-Propanediol (izwi nka Propanediol nyuma y'ibi) ishobora kongera ubushobozi bw'imiti irinda ubushyuhe. Propanediol ntabwo ifatwa nk'imiti irinda ubushyuhe ubwayo, ahubwo ishobora no gukora nk'iyongera mu buryo bwinshi bwo kwirinda ubushyuhe. Propanediol ni itera imbaraga cyane cyane mu miti ishingiye kuri Phenoxyethanol irwanya bagiteri (zaba garama nziza na garama mbi) ndetse n'umusemburo. Gukoresha Propanediol bishobora kugabanya cyane ingano y'imiti irinda ubushyuhe ikenewe muri iyo miti.
