1,3-Propanediol (a na-akpọ ya Propanediol ma emechaa), a na-ejikarị ya eme ihe dị ka ihe mgbaze. Ọ nwere ike idozi akpụkpọ anụ mebiri emebi na ngwaahịa nlekọta ntutu, mee ka ntutu dị nro. Na-egbochi ntutu iwe, tinye 5%. A na-ejikwa ya dị ka ihe na-achịkwa viscosity. 1,3-Propanediol dị ọcha nwere pH dị nso na 7, ọbụlagodi na njupụta karịrị 70%, ọ dịghị enwe mgbakasị ahụ ma ọ bụ mmetụta.
Propanediol na-eme ka mmiri dị ọcha mgbe ejiri ya na ntutu na ihe ndị e ji eme ihe n'ahụ, na pasentị ise, ọ na-arụ ọrụ nke ọma karịa Propylene glycol na Butylene glycol. Mgbe ejikọtara ya na Glycerin, Propanediol na-egosi mmetụta njikọta nke na-ebelata ike Glycerin, ebe ọ na-enye uru nke mmụba nke mmiri mmiri. Na ọkwa ruru pasentị iri asaa na ise, ọ na-egosi obere ike ịkpasu akpụkpọ ahụ iwe ma ọ bụ mee ka ọ dị nro.
1,3-Propanediol (nke a na-akpọ Propanediol ma emechaa) nwere ike ime ka arụmọrụ nke ihe nchekwa dịkwuo mma. A naghị ewere Propanediol dị ka ihe nchekwa n'onwe ya, mana ọ nwere ike ịrụ ọrụ dị ka ihe nkwado n'ọtụtụ sistemụ nchekwa. Propanediol bụ ihe nkwado dị irè karịsịa na usoro Phenoxyethanol megide nje bacteria (ma gram positive na negative) na yist. Ojiji nke Propanediol nwere ike ibelata nke ukwuu ọnụọgụ ihe nchekwa dị mkpa na usoro ahụ.
