ʻO Octocrylene (CAS:6197-30-4) me ka ʻike kikoʻī

ʻO Octylin, ka inoa Pelekane ʻo OCTOCRYLENE, alias: 2-cyano-3,3-diphenyl acrylic acid isooctyl ester, octyl octyl ester. I nā mea hoʻonani a me nā huahana mālama ʻili, hoʻohana nui ʻia ʻo Octalin ma ke ʻano he sunscreen kemika, me kahi kumu pilikia o 3. He palekana a hiki ke hoʻohana maʻalahi ʻia. ʻAʻohe ona hopena i nā wahine hāpai ma ke ʻano holoʻokoʻa. ʻAʻole ʻo Octalin ke kumu o ka ʻākena. No ka mea hoʻomoʻa ultraviolet cinnamic acid, a ʻo ka lōʻihi o ka nalu omo o ka mālamalama ultraviolet he 308nm. Loaʻa iā Octocrylene a me nā hui ʻē aʻe ka hopena maʻamau o ke apo benzene a me ka hui kipi, kahi e loaʻa ai iā lākou ke koina molar absorption kiʻekiʻe ma ka ʻāpana ultraviolet, ʻoi aku hoʻi no ka mālamalama ultraviolet (UVB) me ka nalu ma ka pae o 280 ~ 320nm. ʻO ka hapa nui o nā kukuna ultraviolet i loko o kēia kāʻei e omo ʻia e ka ʻili. ʻO ka hoʻohana lōʻihi ʻana e hoʻoulu ai i ka ʻulaʻula o ka ʻili, ka pehu ʻana, ka ʻelemakule, a me ke kanesa ʻili. ʻO ke kāʻei ultraviolet e pono e kālele ʻia i ka pale ʻana.

Hoʻopaʻa ia i ka avobenzone a hoʻolilo iā ia i mea kūpono. He lā pale lā maikaʻi ʻo Avobenzone e kūʻē i ka UVA nalu lōʻihi. ʻAʻole maʻalahi ke komo ʻana o kēia mea hoʻohui a palekana loa ia no ke kino kanaka, akā ʻo kekahi o kona mau hemahema make loa, ʻo ia ka hoʻokuʻu ʻana i nā radical manuahi i ka lā. I ka hoʻohana ʻana i nā lā pale lā e loaʻa ana iā Aucklylin, ua ʻōlelo ʻia e hoʻohana pū me ka ʻano antioxidant e pale aku i ka pōʻino o nā radical manuahi.
