Cosmate®AVB ,ʻAvobenzone,Butyl Methoxydibenzoylmethane. He mea ia o ka dibenzoyl methane. Hiki ke hoʻopili ʻia e ka avobenzone kahi ākea ākea o nā lōʻihi kukui ultraviolet. Aia ia i loko o ka nui o nā sunscreens ākea ākea i loaʻa i ke kālepa. Hana ia ma ke ʻano he sunblock. ʻO kahi pale UV topical me kahi kikoʻī ākea, nā poloka avobenzone i UVA I, UVA II, a me UVB nā lōʻihi hawewe, e hōʻemi ana i ka pōʻino i hiki i nā kukuna UV ke hana i ka ʻili.
ʻO ka Avobenzone (BMDM, Butyl methoxydibenzoylmethane) he lāʻau kemika pale e hāʻawi ana i ka pale ākea i nā kukuna UVA. Hoʻopili ʻo Avobenzone i nā kukuna UV-(380-315 nm e pili ana i ka pōʻino o ka ʻili lōʻihi) a me UV-B (315-280 nm e hoʻoulu ai i ka lā). ʻIke ʻia ʻo Avobenzone ma ke ʻano he hoʻokahi o nā mea hoʻohana pale lā.
ʻAvobenzoneHe mea hoʻohana nui ʻia ka lāʻau pale lā i ʻike ʻia no kona hiki ke hāʻawi i ka pale ākea ākea i nā kukuna UVA. ʻO ia kekahi o nā kānana UVA maikaʻi loa i loaʻa a loaʻa pinepine ʻia i nā pale lā, nā moisturizers, a me nā huahana mālama lā. ʻO kona hiki ke komo i ka radiation UVA e kōkua i ka pale ʻana i ka paʻi kiʻi, ka lā, a me ka pōʻino ʻili lōʻihi.
Nā Hana Nui o Avobenzone
* Palena UVA ākea ākea: Hoʻopau i nā kukuna UVA, nona ke kuleana no ka ʻelemakule mua a me ka pōʻino o ka ʻili.
* Kāohi Paʻi Kiʻi: Mālama i ka ʻili mai nā wrinkle i hoʻokomo ʻia e UVA, nā laina maikaʻi, a me ka nalowale o ka elasticity.
*Pale ʻana i ka lā: Hana pū me nā kānana UVB e hāʻawi i ka pale piha i ka lā.
*Stabilized Formulations: Hoʻohana pinepine ʻia me nā stabilizers e hoʻonui i kona photostability a me ka pono.
*Kili Pili: He kūpono no nā ʻano ʻili ākea, me ka ʻili paʻakikī.
Avobenzone Mechanism of Action
*UVA Absorption: Hoʻopau i ka radiation UVA (320-400 nm) a hoʻololi iā ia i ikehu wela liʻiliʻi, e pale ana i ka pōʻino DNA.
*Free Radical Neutralization: Kōkua e hōʻemi i ka hoʻokumu ʻana o nā radical manuahi i hoʻokumu ʻia e ka ʻike ʻana o UV, e hōʻemi ana i ke kaumaha oxidative.
* Palekana Collagen: Kāohi i ka haki ʻana o ka collagen a me ka elastin i ka UVA, mālama i ka paʻa a me ka elasticity.
* Nā hopena Synergistic: Hoʻohui pinepine ʻia me nā kānana UVB (e laʻa, octinoxate) a me nā stabilizers (e laʻa, octocrylene) e hoʻonui i kona photostability a me ka pale ākea ākea.
ʻO nā pono a me nā pono o Avobenzone
*Ka palekana UVA maikaʻi: Hāʻawi i ka pale maikaʻi loa mai nā kukuna UVA, ʻo ia ke kumu nui o ke kiʻi ʻana.
* Ka hoʻohālikelike ʻana i ka laulā ākea: Hana maikaʻi me nā kānana UV ʻē aʻe e hāʻawi i ka pale ʻana i ka lā holoʻokoʻa.
*Photostability: Ke hoʻopaʻa ʻia, hoʻomau ʻia ia ma lalo o ka hoʻolaha UV lōʻihi.
*Malu ma ka ʻili: He kūpono no nā ʻano ʻili āpau, me ka ʻili koʻikoʻi, ke hana pololei ʻia.
*Apono Hoʻoponopono: Apono ʻia e nā kino hoʻoponopono nui, me ka FDA a me EU, no ka hoʻohana ʻana i nā pale lā.
