Ko te 1,3-Propanediol (e kiia nei ko te Propanediol i muri nei), e whakamahia ana hei whakarewa. Ka taea e ia te whakatika i ngā unahi huruhuru kua pakaru i roto i ngā hua tiaki makawe, kia maeneene ake ai te makawe. Ārai i te riri o te makawe, tāpirihia he 5%. Ka whakamahia hoki hei kaihoko whakahaere matotoru. He tata ki te 7 te pH o te 1,3-Propanediol parakore, ā, ahakoa he nui ake i te 70% te kukū, kāore he riri kiri, he pāwera rānei.
Ka whakanui ake te propanediol i te makuku ina whakamahia i roto i ngā hua makawe me te tinana, ā, i te 5%, ka pai ake te mahi i te Propylene glycol me te Butylene glycol. Ina honoa ki te Glycerin, ka whakaatu te Propanediol i te pānga mahi tahi e whakaiti ana i te piri o te Glycerin, me te tuku hoki i ngā painga o te pikinga o ngā taumata makuku. I ngā taumata tae atu ki te 75%, e whakaatu ana i te iti o te kaha ki te whakapataritari, ki te whakararuraru rānei i te kiri.
Tērā pea ka whakanui ake te 1,3-Propanediol (e kiia nei ko Propanediol i muri nei) i te whai huatanga o ngā mea tiaki. Kāore te propanediol e kiia he mea tiaki tonu, engari ka taea te mahi hei whakakaha i roto i te maha o ngā pūnaha tiaki. He whakakaha whai hua te propanediol, inā koa i roto i ngā whakatakotoranga e hangai ana ki te Phenoxyethanol hei patu i ngā huakita (gram pai me te kino) me ngā rewena. Mā te whakamahinga o te propanediol ka taea te whakaiti nui i te nui o ngā mea tiaki e hiahiatia ana i roto i te whakatakotoranga.
