1,3-Propanediol (i kapa ʻia ʻo Propanediol ma hope aku), hoʻohana nui ʻia e like me ka solvent.Hiki iā ia ke hoʻoponopono i nā unahi huluhulu pohō i nā huahana mālama lauoho, e hoʻomaʻemaʻe i ka lauoho.Kāohi i ka lauoho irritable, hoʻohui i 5%.Hoʻohana pū ʻia ma ke ʻano he mea hoʻomalu viscosity.Loaʻa ka 1,3-Propanediol maʻemaʻe i ka pH kokoke i ka 7 a hiki i nā ʻike kiʻekiʻe ma mua o 70% ʻaʻohe ʻili a i ʻole ka ʻike.

Hoʻonui ka propanediol i ka hydration ke hoʻohana ʻia i ka lauoho a me nā huahana kino, a ma ka 5%, ʻoi aku ka maikaʻi ma mua o propylene glycol a me Butylene glycol.Ke hui pū ʻia me Glycerin, hōʻike ʻo Propanediol i kahi hopena synergistic e hōʻemi ana i ka tackiness o Glycerin, ʻoiai e hāʻawi ana i nā pono o ka piʻi ʻana o ka hydration.Ma nā pae a hiki i ka 75%, hōʻike ia i ka haʻahaʻa haʻahaʻa e hoʻonāukiuki a i ʻole ka ʻili.

1,3-Propanediol (i kapa ʻia ʻo Propanediol ma hope) hiki ke hoʻonui i ka pono o nā preservatives.ʻAʻole i manaʻo ʻia ʻo Propanediol he mea hoʻomalu ponoʻī, akā hiki ke hana i mea hoʻoikaika i nā ʻōnaehana preservative.He mea hoʻoikaika maikaʻi ʻo Propanediol i ka hoʻokumu ʻana o Phenoxyethanol e kūʻē i ka bacteria (ʻelua gram maikaʻi a maikaʻi ʻole) a me nā hū.Hiki i ka hoʻohana ʻana o Propanediol ke hōʻemi nui i ka nui o nā preservatives e pono ai i ka hoʻokumu ʻana.
