ʻO ka pūhui kemika waiʻona kekahi ʻano o nā mea hoʻohuihui i loaʻa i kahi hui hydroxyl (-OH) i hoʻopaʻa ʻia i kahi ʻātoma kalapona.Hoʻohana maʻamau ia i nā ʻoihana e like me nā lāʻau lapaʻau, nā mea hoʻonaninani, a me ka hana wahie.ʻO ka ethanol, ka methanol, a me ka propanol kekahi o nā waiʻona i hoʻohana mau ʻia.Loaʻa pinepine ʻia ka Ethanol i nā mea inu ʻawaʻawa a hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe, wahie, a me ka antiseptic.Hoʻohana ʻia ka Methanol ma ke ʻano he mea hoʻoheheʻe a me ka wahie, a hoʻohana mau ʻia ka propanol i nā mea hoʻonaninani a me nā lāʻau lapaʻau.Loaʻa i nā waiʻona nā waiwai kino a me nā kemika e pono ai i nā ʻoihana he nui.Eia nō naʻe, hiki iā lākou ke lilo i mea ʻawaʻawa a hiki ke puhi ʻia, e hoʻoweliweli iā lākou inā ʻaʻole mālama pono ʻia.
