He aha ka hoʻohana ʻana o Avobenzone?

Avobenzone,ʻike ʻia hoʻi ʻo Parsol 1789 a i ʻole butyl methoxydibenzoylmethane, he hui kemika i hoʻohana mau ʻia ma ke ʻano he mea hoʻohui i nā pale lā a me nā huahana mālama pilikino ʻē aʻe. He mea hoʻoheheʻe UV maikaʻi loa ia e kōkua i ka pale ʻana i ka ʻili mai nā kukuna UVA ʻino, ʻo ia ke kumu i loaʻa pinepine ai i nā sunscreens ākea ākea.

ʻO ka helu CAS o Avobenzone he 70356-09-1. He pauda melemele ia, ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai akā hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik, me ka aila a me nā ʻawaʻawa. ʻO ka Avobenzone kahi mea hiki ke kiʻi kiʻi, ʻo ia hoʻi, ʻaʻole ia e wāwahi i ka wā e ʻike ʻia ai ka lā, e lilo ia i koho kaulana no nā sunscreens.

ʻAvobenzonehoʻopaʻa i nā kukuna UVA ma ka hoʻololi ʻana iā lākou i ka ikehu liʻiliʻi ma mua o ke komo ʻana i ka ʻili. He kiʻekiʻe loa ka absorbance peak o ka pūhui ma 357 nm a maikaʻi loa i ka pale ʻana i ka radiation UVA. Ua ʻike ʻia nā kukuna UVA e hoʻoulu i ka wā ʻelemakule, nā wrinkles, a me nā mea ʻino ʻē aʻe o ka ʻili, no laila, ʻo ka avobenzone kahi mea pāʻani waiwai i ka pale ʻana i ka ʻili mai nā hopena o ka lā.

Ma waho aʻe o nā pale lā,avobenzonehoʻohana pū ʻia i nā huahana mālama pilikino ʻē aʻe, e like me nā moisturizers, lip balms, a me nā huahana mālama lauoho. ʻO kāna pale ākea ākea e kūʻē i nā kukuna UVA he mea pono ia i nā huahana like ʻole e ʻimi nei e pale i ka ʻili a me ka lauoho mai ka pōʻino.

ʻOiai kekahi mau hopohopo e pili ana i ka palekana o ka avobenzone, ua hōʻike nā haʻawina he palekana a maikaʻi hoʻi ke hoʻohana ʻia e like me ke kuhikuhi ʻana i nā sunscreens a me nā huahana mālama pilikino. Hoʻokomo ʻia ia ma ka papa inoa o ka FDA o nā mea hana i ʻae ʻia no ka hoʻohana ʻana i nā pale lā ma luna o ka counter, a hoʻohana nui ʻia i nā ʻano huahana like ʻole.

Nui,avobenzoneHe mea waiwai ia i loko o nā huahana mālama pilikino he nui, ʻoi aku ka sunscreens, ma muli o kona hiki ke pale aku i nā kukuna UVA ʻino. ʻO kona photostability a me ka hiki ke hoʻohana ʻia i nā ʻano ʻano like ʻole e lilo ia i mea hoʻohui like ʻole e noho nei. No laila, i ka wā e ʻimi ai ʻoe i kahi pale lā, e nānā i ka avobenzone ma ka papa inoa o nā mea hana e hōʻoia ai e loaʻa ana iā ʻoe ka palekana maikaʻi loa.
