He mea ino anei ka hydroxyethyl cellulose?

ʻO ka Hydroxyethyl cellulose (HEC) he polymer non-ionic, wai-soluble i loaʻa mai ka cellulose, he mea maoli ia i loaʻa i loko o nā paia pūnaewele o nā mea kanu. Loaʻa iā ia ka nui o nā noi i nā ʻoihana like ʻole, me nā lāʻau lapaʻau, nā mea hoʻonaninani, nā meaʻai, a me ke kūkulu ʻana, ma muli o kona mānoanoa, hoʻopaʻa, emulsifying, a me ka hoʻopaʻa ʻana i nā waiwai. Eia nō naʻe, e like me nā mea ʻē aʻe, pili ka palekana o HEC i kāna hoʻohana kikoʻī, ka noʻonoʻo, a me ka ʻike.

Ma keʻano laulā, manaʻo ʻia ʻo HEC he palekana no ka hoʻohana ʻana i nā ʻoihana i ʻōlelo ʻia i ka wā i hoʻohana ʻia i loko o nā kuhikuhi i kuhikuhi ʻia. Eia naʻe, aia kekahi mau manaʻo e noʻonoʻo e pili ana i kona palekana:

Oral Ingestion: ʻOiai ʻike ʻia ʻo HEC he palekana no ka hoʻohana ʻana i ka meaʻai a me nā noi lāʻau lapaʻau, hiki i ka ʻai nui ʻana o HEC ke alakaʻi i ka ʻeha o ka ʻōpū. Eia nō naʻe, pono e hoʻomaopopo ʻaʻole ʻai ʻia ka HEC maʻamau a loaʻa mau i nā huahana i nā haʻahaʻa haʻahaʻa loa.

Hoʻomaʻamaʻa ʻili: I nā mea hoʻonaninani a me nā huahana mālama pilikino, hoʻohana maʻamau ʻia ʻo HEC ma ke ʻano he mānoanoa, hoʻopaʻa, a me ka stabilizer i nā hana e like me nā creams, lotions, a me nā shampoos. Manaʻo maʻamau ia he palekana no ka hoʻohana ʻana i ke kumuhana, akā hiki i kekahi poʻe ke ʻike i ka ʻili ʻili a i ʻole ka maʻi maʻi i HEC, ʻoi aku ka nui inā loaʻa iā lākou nā ʻano maʻamau i ka cellulose derivatives.

Huhu Maka: I kekahi mau hihia, hiki i nā huahana i loaʻa iā HEC, e like me nā hāʻule o ka maka a i ʻole nā ​​ʻoluʻolu lens contact, hiki ke hoʻonāukiuki i nā maka, ʻoiai inā ua haumia a hoʻohana pono ʻia ka huahana. Pono nā mea hoʻohana e hahai mau i nā ʻōlelo kuhikuhi no ka hoʻohana ʻana a e ʻimi i ka lāʻau lapaʻau inā loaʻa ka huhū.

ʻIke ʻana i ka hanu: ʻO ka hoʻohu ʻana i ka lepo HEC a i ʻole nā ​​​​aerosol hiki ke hoʻoulu i ka ʻeha a i ʻole ka ʻike ʻana i kekahi poʻe, ʻoi aku ka poʻe me nā maʻi hanu a i ʻole nā ​​​​mea ʻeleʻele i ka ea. Pono e hoʻopaʻa ʻia ka mālama pono ʻana a me ka ea i ka wā e hana ai me nā ʻano pauda o HEC.

Ka hopena o ke kaiapuni: ʻOiai ʻo HEC ponoʻī he biodegradable a maikaʻi hoʻi i ke kaiapuni, hiki i ke kaʻina hana hana a me ka hoʻokuʻu ʻana i nā huahana HEC i loaʻa i nā hopena kaiapuni. Pono e hoʻoikaika ʻia e hōʻemi i ka ʻōpala a me ka haumia e pili ana i ka hana ʻana, hoʻohana, a me ka hoʻolei ʻana i nā huahana HEC.

ʻO nā keʻena hoʻoponopono e like me ka US Food and Drug Administration (FDA), ka European Food Safety Authority (EFSA), a me ka Cosmetic Ingredient Review (CIR) Expert Panel ua loiloi i ka palekana o HEC a ua manaʻo ʻia he palekana ia no kāna hoʻohana ʻana i loko o ka mea i kuhikuhi ʻia. hoʻopaʻa ʻana. Eia nō naʻe, he mea nui i nā mea hana e hoʻopili i nā alakaʻi hoʻoponopono a hōʻoia i ka maikaʻi a me ka palekana o kā lākou huahana ma o ka hoʻāʻo kūpono a me nā ana kaohi maikaʻi.

ʻO ka hydroxyethyl cellulose ka mea maʻamau i manaʻo ʻia he palekana no ka hoʻohana ʻana i nā ʻoihana like ʻole ke hoʻohana pono ʻia a ma loko o nā kuhikuhi i kuhikuhi ʻia. Eia nō naʻe, e like me nā mea kemika, pono e hahai ʻia nā hana kūpono, mālama, a me ka hoʻolei ʻana i mea e hōʻemi ai i nā pilikia i ke olakino kanaka a me ke kaiapuni. Pono nā kānaka me nā hopohopo kūikawā e pili ana i ka HEC a i ʻole nā ​​​​huahana i loaʻa iā HEC e kūkākūkā me nā limahana mālama olakino a i ʻole nā ​​mana hoʻoponopono no ka ʻōlelo aʻo pilikino.
