ʻO ka Hydroxyethylcellulose (HEC) he polymer hiki ke hoʻoheheʻe ʻia i ka wai i hoʻohana mau ʻia i ka hana ʻana i nā gels ma muli o kona mānoanoa, hoʻopaʻa, a me nā waiwai gelling. Hoʻohana ʻia nā gel HEC i nā ʻano noi like ʻole, me nā huahana mālama pilikino, nā lāʻau lapaʻau, a me nā meaʻai.
No ka hana ʻana i kahi gel HEC, hoʻopuehu mua ʻia ka polymer i ka wai a laila hui ʻia a hiki i ka hydrated piha. Pono kēia i ka hoʻoulu ʻana a i ʻole ka hui ʻana no kekahi mau minuke e hōʻoia i ka hoʻopuehu piha ʻana o ka polymer a me ka hydrated. ʻO ka hopena HEC e hoʻomehana ʻia i kahi mahana kikoʻī, e hilinaʻi ana i ka pae kikoʻī o HEC i hoʻohana ʻia, e hoʻāla i nā waiwai gelling o ka polymer.
Hiki ke hoʻololi hou ʻia ka gel HEC e ka hoʻohui ʻana i nā mea ʻē aʻe, e like me nā mea hana, nā mea ʻala, a me nā kala. ʻO ka hoʻonohonoho kikoʻī o ka gel e hilinaʻi i nā waiwai i makemake ʻia o ka huahana hope.
ʻO kekahi o nā pōmaikaʻi o ka hoʻohana ʻana i ka HEC i ka hoʻokumu ʻana i ka gel ʻo ia ka hiki ke hāʻawi i kahi ʻano maʻemaʻe a me ka momona i ka huahana hope. He paʻa loa nā gels HEC a hiki ke mālama i ko lākou ʻano a me ka viscosity ma luna o kahi ākea o nā mahana a me nā pae pH.
Ma waho aʻe o kāna mau mea hoʻokūpaʻa a me ka mānoanoa, loaʻa iā HEC nā waiwai moisturizing a me nā mea hana kiʻiʻoniʻoni, hiki iā ia ke lilo i mea hoʻohana pono i nā huahana mālama pilikino e like me nā moisturizers a me nā sunscreens. Hiki ke hoʻohana ʻia ʻo HEC ma ke ʻano he suspending agent i nā formulations e koi ai i ka hāʻawi like ʻana o nā ʻāpana a i ʻole nā mea ʻai.
Hoʻohana pinepine ʻia nā gel HEC i nā ʻano huahana mālama pilikino, e like me nā gel lauoho, nā mea hoʻomaʻemaʻe maka, a me nā holoi kino. Hiki ke hoʻohana ʻia i nā lāʻau lapaʻau ma ke ʻano he ʻōnaehana hoʻopuka no nā lāʻau lapaʻau topical a i ʻole he mea mānoanoa i nā lāʻau wai.
