Kānana UV Octyl Methoxycinnamate CAS 5466-77-3 Octyl 4-Methoxycinnamate

ʻO Octyl methoxycinnamate, i ʻike ʻia ʻo ethylhexyl methoxycinnamate (EHMC), he mea hoʻohui i hoʻohana mua ʻia ma ke ʻano he kānana UV i nā huahana hoʻonaninani a me nā huahana mālama pilikino. Loaʻa iā ia ke ʻano kemika C16H24O3 a ua helu ʻia ma ke ʻano he ester methoxycinnamate. Ua ʻike nui ʻia kēia pūhui no kona hiki ke komo i ka radiation ultraviolet (UV), ʻo ia hoʻi nā kukuna UVB, he mea pōʻino i ka ʻili kanaka.

Ke Kinohi a me nā waiwai

ʻO ke kemika, loaʻa mai ka octyl methoxycinnamate mai ka methoxycinnamic acid, he mea ia o ka cinnamic acid me kahi hui methoxy i hoʻopili ʻia. ʻO ka octyl moiety, i loaʻa mai ka 2-ethylhexanol, hāʻawi i ka pūhui me nā waiwai lipophilic, e hoʻoheheʻe ʻia i loko o nā aila a me nā mea hoʻoheheʻe organik ʻē aʻe, no laila e hoʻonui ai i kona kūlike me nā mea hoʻonaninani.

Hōʻike ʻo Octyl methoxycinnamate i kahi kikoʻī hoʻoheheʻe ʻana o UV, ʻoi aku ka nui o ka lawe ʻana i ka radiation UVB ma ka laulā o 280 a 320 nanometers (nm). He mea koʻikoʻi kēia ʻano no ka mea ʻo nā kukui UVB ke kuleana no ka sunburn a kōkua i ka pōʻino o ka ʻili, me ka ʻelemakule mua a me ka piʻi nui ʻana o nā maʻi maʻi ʻili. Ma ka lawe ʻana i kēia mau kukuna ʻino, kōkua ka octyl methoxycinnamate i ka pale ʻana i ka ʻili mai kēia mau hopena ʻino.

Hoʻohana ʻia i nā mea hoʻonaninani a me nā huahana pale lā

I loko o ka ʻoihana hoʻonaninani, ʻo ka octyl methoxycinnamate kahi mea hoʻohana nui ʻia i ka hoʻokumu ʻana o ka sunscreen. Hoʻohui pinepine ʻia me nā kānana UV ʻē aʻe e hana i nā sunscreens ākea ākea e hāʻawi i ka pale mai ka UVA a me ka UVB radiation. He mea koʻikoʻi ka hui ʻana o nā kānana ʻokoʻa no ka mea e hoʻopaʻa ʻia kēlā me kēia ʻano kānana i kahi kikoʻī kikoʻī o nā lōʻihi nalu, a laila e hāʻawi i ka pale ākea.

Hoʻolālā maʻamau ʻia nā sunscreens i loaʻa i ka octyl methoxycinnamate i mea e pale ai i ka wai, e hōʻoia ana i ka maikaʻi o ka huahana ma hope o ka ʻike ʻana i ka wai a i ʻole ka hou. He mea koʻikoʻi kēia no nā hana o waho a me nā haʻuki, kahi e holoi ʻia ai nā pale lā kahiko, e waiho ana i ka ʻili i ka pōʻino UV.

Nā Manaʻo Palekana a Hoʻoponopono

Ua loiloi nui ʻia ka palekana o ka octyl methoxycinnamate e nā kino hoʻoponopono e like me ka US Food and Drug Administration (FDA) a me ka European Commission's Scientific Committee on Consumer Safety (SCCS). Wahi a kēia mau hui, ua manaʻo ʻia ka octyl methoxycinnamate i palekana no ka hoʻohana ʻana i nā huahana cosmetic, me nā sunscreens, ke hoʻohana ʻia i loko o nā palena o ka manaʻo.

Eia nō naʻe, e like me nā kānana UV kemika, hiki i ka octyl methoxycinnamate ke loaʻa i nā hopena maikaʻi ʻole ke hoʻohana hewa ʻia a inā ʻoi aku ka nui o ka ʻike ma mua o nā pae i ʻōlelo ʻia. Ua manaʻo kekahi mau haʻawina e hoʻoulu ai i ka huhū a i ʻole ka maʻi maʻi i nā poʻe maʻi. No laila, pono i nā mea hana ke hoʻopili i nā alakaʻi i hāʻawi ʻia e nā kino hoʻoponopono a no nā mea kūʻai aku e heluhelu pono a hahai i nā ʻōlelo kuhikuhi.

Ka hopena o ke kaiapuni

ʻO ka hopena kaiapuni o ka octyl methoxycinnamate kahi kumuhana o ka noiʻi mau. Ua hōʻike ʻia kekahi mau haʻawina e hiki ke loaʻa i kahi hopena ʻona i hilinaʻi ʻia i nā mea ola wai, ʻoi aku ma nā pae kiʻekiʻe. Ua alakaʻi kēia i nā hopohopo e pili ana i ka hiki ke hōʻiliʻili ʻia i loko o nā kaiapuni kai, ʻo ia hoʻi ma nā wahi kahakai kahi i hoʻohana nui ʻia ai nā huahana pale lā.

ʻO ka hopena, ke ulu nei ka hoihoi i ka hoʻomohala ʻana i nā mea ʻē aʻe e pili ana i ka lā. ʻOiai e mau ana ka octyl methoxycinnamate i kānana UV i hoʻohana nui ʻia a maikaʻi hoʻi, ua hoʻoikaika kona hopena kaiapuni i ka ʻimi ʻana i nā koho hoʻomau hou aku, e like me nā mea pale kino (e laʻa, zinc oxide a me titanium dioxide) a me nā kānana kemika hou i ʻoi aku ka pōʻino i ke ola wai.
