1,3-Propanediol (oo loo yaqaan Propanediol wixii ka dambeeya), inta badan waxaa loo isticmaalaa dareere ahaan. Waxay hagaajin kartaa qolofta dhogorta ee dhaawacan ee alaabada daryeelka timaha, waxayna ka dhigi kartaa timaha kuwo siman. Waxay ka hortagtaa cuncunka timaha, ku dar 5%. Sidoo kale waxaa loo isticmaalaa sidii wakiilka xakamaynta viscosity. Saafiga ah 1,3-Propanediol wuxuu leeyahay pH u dhow 7 xitaa marka uu ka sarreeyo 70% ma jiro cuncun maqaarka ama dareen-celin.
Propanediol waxay kordhisaa fuuq-baxa marka loo isticmaalo timaha iyo waxyaabaha jirka laga sameeyo, 5%-na, waxay ka fiican tahay Propylene glycol iyo Butylene glycol. Marka lagu daro Glycerin, Propanediol waxay muujisaa saameyn isku-dhafan oo yareysa jilicsanaanta Glycerin, iyadoo bixinaysa faa'iidooyinka heerarka fuuq-baxa oo kordha. Heerarka ilaa 75%, waxay muujinaysaa awood yar oo lagu xanaaqo ama lagu dareensiiyo maqaarka.
1,3-Propanediol (oo loo yaqaan Propanediol wixii ka dambeeya) waxay kor u qaadi kartaa waxtarka ilaaliyayaasha. Propanediol looma tixgeliyo inuu yahay ilaaliye lafteeda, laakiin wuxuu u dhaqmi karaa sidii xoojiye nidaamyo badan oo ilaalin ah. Propanediol waa xoojiye wax ku ool ah gaar ahaan qaacidooyinka ku salaysan Phenoxyethanol ee ka dhanka ah bakteeriyada (labada garaam togan iyo kuwa tabanba) iyo khamiirka. Isticmaalka Propanediol wuxuu si weyn u yareyn karaa xaddiga ilaaliyayaasha loo baahan yahay ee ku jira qaacidada.
