He aha nā Nanoparticles i ka Sunscreen?

Ua hoʻoholo ʻoe ʻo ka hoʻohana ʻana i ka pale lā maoli ka koho kūpono no ʻoe. Manaʻo paha ʻoe ʻo ia ka koho maikaʻi loa no ʻoe a me ke kaiapuni, a i ʻole ka pale lā me nā mea hana synthetic e hoʻonāukiuki i kou ʻili oh-so-sensitive.

A laila lohe ʻoe e pili ana i nā "nanoparticles" i loko o kekahi mau pale lā maoli, me kekahi ʻike weliweli a paio hoʻi e pili ana i nā ʻāpana e hāʻawi iā ʻoe i ka hoʻomaha. ʻO kaʻoiaʻiʻo, pono anei ke koho ʻana i kahi pale lā kūlohelohe?

Me ka nui o ka ʻike ma laila, hiki ke manaʻo nui loa. No laila, e ʻoki kākou i ka walaʻau a nānā pono ʻole i nā nanoparticles i ka sunscreen, ko lākou palekana, nā kumu e makemake ai ʻoe iā lākou i loko o kāu pale lā a inā ʻaʻole ʻoe.

He aha nā Nanoparticles?

ʻO nā nanoparticles he mau ʻāpana liʻiliʻi loa o kahi mea i hāʻawi ʻia. ʻOi aku ka mānoanoa o nā nanoparticles ma mua o 100 nanometers. No ka hāʻawi ʻana i kekahi hiʻohiʻona, ʻo ka nanometer he 1000 mau manawa liʻiliʻi ma mua o ka mānoanoa o hoʻokahi kaula lauoho.

ʻOiai hiki ke hana maoli ʻia nā nanoparticles, e like me nā kulu liʻiliʻi o ka ehu kai no ka laʻana, hana ʻia ka hapa nui o nā nanoparticles i ka lab. No ka pale lā, ʻo nā nanoparticles i nīnau ʻia he zinc oxide a me titanium dioxide. Hoʻopau ʻia kēia mau mea i loko o nā ʻāpana ultra-fine ma mua o ka hoʻohui ʻia ʻana i kāu pale lā.

Ua loaʻa mua nā nanoparticles i nā pale lā i ka makahiki 1980, akā ʻaʻole i loaʻa a hiki i ka makahiki 1990. I kēia lā, hiki iā ʻoe ke manaʻo i kāu pale lā maoli me ka zinc oxide a / a i ʻole titanium dioxide he mau mea nano-nui ke ʻole i kuhikuhi ʻia.

ʻO nā huaʻōlelo "nano" a me "micronized" he like like. No laila, ʻo ka pale lā e kau ana i ka "micronized zinc oxide" a i ʻole "micronized titanium dioxide" lepili aia nā nanoparticles.

ʻAʻole loaʻa nā nanoparticles i nā pale lā. Nui nā mea mālama ʻili a me nā mea hoʻonaninani, e like me nā kumu, nā shampoos, a me nā niho niho, loaʻa pinepine nā mea micronized. Hoʻohana pū ʻia nā nanoparticles i nā mea uila, nā lole, nā aniani pale pale, a me nā mea hou aku.

Mālama nā Nanoparticles i nā pale lā maoli mai ka waiho ʻana i kahi kiʻiʻoniʻoni keʻokeʻo ma kou ʻili

Ke koho ʻana i kāu pale lā maoli, ʻelua mau koho; nā mea me nā nanoparticles a me nā mea ʻole. E ʻike ʻia ka ʻokoʻa ma waena o nā mea ʻelua ma kou ʻili.

Ua ʻae ʻia ka titanium dioxide a me ka zinc oxide e ka FDA ma ke ʻano he mea hoʻonaninani kūlohelohe. Hāʻawi kēlā me kēia i ka pale UV ākea ākea, ʻoiai ʻoi aku ka maikaʻi o ka titanium dioxide i ka hui pū ʻana me ka zinc oxide a i ʻole kekahi mea hoʻonaninani sunscreen.

Hana ʻia ka Zinc oxide a me ka titanium dioxide ma ka hoʻohālikelike ʻana i nā kukuna UV mai ka ʻili, e pale ana i ka ʻili mai ka lā. A maikaʻi loa lākou.

I ko lākou ʻano maʻamau, ʻaʻole nano-nano nui, zinc oxide a me titanium dioxide he keʻokeʻo loa. Ke hoʻokomo ʻia i loko o ka pale lā, e waiho lākou i kahi kiʻiʻoniʻoni keʻokeʻo opaque ma ka ʻili. E noʻonoʻo i ka mea mālama ola stereotypical me ke keʻokeʻo ma ke alahaka o ka ihu-ʻae, ʻo ia ka zinc oxide.

E hoʻokomo i nā nanoparticles. ʻOi aku ka maikaʻi o ka pale lā i hana ʻia me ka zinc oxide micronized a me ka titanium dioxide i loko o ka ʻili, a ʻaʻole e waiho i hope o ka nānā ʻana. ʻO nā nanoparticles maikaʻi loa e hoʻemi iki i ka pale lā akā e like me ka maikaʻi.

ʻIke ʻia ka hapa nui o ka noiʻi i nā nanoparticles i ka pale ʻana i ka lā

Mai ka mea a mākou i ʻike ai i kēia manawa, ʻaʻole ʻike ʻia nā nanoparticles o ka zinc oxide a i ʻole titanium dioxide i mea pōʻino ma kekahi ʻano. Eia naʻe, ʻo nā hopena lōʻihi o ka hoʻohana ʻana i ka micronized zinc oxide a me ka titanium dioxide, he mea pohihihi. I nā huaʻōlelo ʻē aʻe, ʻaʻohe mea hōʻoia e palekana loa ka hoʻohana ʻana i ka wā lōʻihi, akā ʻaʻohe mea hōʻike ʻino.

Ua nīnau kekahi i ka palekana o kēia mau ʻāpana micronized. Ma muli o ka liʻiliʻi, hiki iā lākou ke komo i ka ʻili a i loko o ke kino. ʻO ka nui o ke komo ʻana a me ka hohonu o ke komo ʻana ma muli o ka liʻiliʻi o ka zinc oxide a i ʻole ka titanium dioxide particle, a me ke ʻano o ka lawe ʻia ʻana.

No nā kiki, he aha ka hopena i kou kino inā hoʻokomo ʻia nā nano-particles zinc oxide a titanium dioxide? ʻO ka mea pōʻino, ʻaʻohe pane akaka no kēlā.

Aia nā manaʻo noʻonoʻo hiki iā lākou ke koʻikoʻi a hōʻino i nā ʻāpana o ko mākou kino, e wikiwiki ana i ka ʻelemakule ma loko a ma waho. Akā, pono e hana ʻia nā noiʻi hou aʻe e ʻike maopopo i kekahi ala a i ʻole.

Ua hōʻike ʻia ka Titanium dioxide, i kona ʻano pauda a inhaled, e hoʻoulu i ka maʻi maʻi maʻi maʻi i nā ʻiole lab. ʻOi aku ka hohonu o ka micronized titanium dioxide i ka ʻili ma mua o ka micronized zinc oxide, a ua hōʻike ʻia ka titanium dioxide e hele i ka placenta a hoʻopaʻa i ka pale koko-lolo.

E hoʻomanaʻo naʻe, ʻo ka hapa nui o kēia ʻike mai ka ʻai ʻana i ka titanium dioxide (no ka mea, loaʻa ia i loko o nā meaʻai a me nā mea ʻono i hoʻopaʻa mua ʻia). Mai nā noiʻi he nui o ka micronized titanium dioxide a me ka zinc oxide i hoʻohana ʻia, i kekahi manawa wale nō kēia mau mea i loaʻa i loko o ka ʻili, a laila aia lākou i nā haʻahaʻa haʻahaʻa loa.

ʻO ia hoʻi, inā ʻoe e hoʻopili i kahi pale lā i loaʻa nā nanoparticles, ʻaʻole paha lākou e komo ma mua o ka papa mua o ka ʻili. ʻOkoʻa ka nui o ka hoʻomoʻa ʻia ʻana ma muli o ke ʻano o ka pale lā, a ʻaʻole e komo hohonu ka nui o ia mea inā ʻaʻole.

Me ka ʻike i loaʻa iā mākou i kēia manawa, ʻike ʻia ka pale lā me nā nanoparticles he palekana a maikaʻi loa. ʻAʻole maopopo ka hopena o ka hoʻohana lōʻihi ʻana o ka huahana i kou olakino, ʻoi aku ka nui inā hoʻohana ʻoe i ka huahana i kēlā me kēia lā. Eia hou, ʻaʻohe mea hōʻoia i ka hoʻohana lōʻihi ʻana i ka micronized zinc oxide a i ʻole titanium dioxide he mea pōʻino, ʻaʻole maopopo mākou i ka hopena (inā loaʻa) i kou ʻili a i ʻole kino.

He huaolelo mai Verywell

ʻO ka mea mua, e hoʻomanaʻo ʻo ka hoʻohana ʻana i ka pale lā i kēlā me kēia lā ʻo ia kekahi o nā mea maikaʻi loa e hiki ai iā ʻoe ke hana no ke olakino lōʻihi o kou ʻili (a ʻo ia hoʻi ke ʻano anti-aging maikaʻi loa). No laila, mahalo iā ʻoe no ka hoʻoikaika ʻana i ka pale ʻana i kou ʻili!

Nui nā pale lā kūlohelohe i loaʻa, nā koho nano a me nā koho ʻole, aia kahi huahana ma laila no ʻoe. ʻO ka hoʻohana ʻana i kahi pale lā me ka micronized (AKA nano-particle) zinc oxide a i ʻole titanium dioxide e hāʻawi iā ʻoe i kahi huahana ʻoi aku ka liʻiliʻi o ka pasty a me ka hamo ʻana.

Inā hopohopo ʻoe e pili ana i nā nano-particles, me ka hoʻohana ʻana i kahi pale lā non-micronized e hāʻawi iā ʻoe i nā ʻāpana nui i emi ʻole ke komo ʻia e kou ʻili. ʻO ke kālepa-off e ʻike ʻoe i kahi kiʻiʻoniʻoni keʻokeʻo ma kou ʻili ma hope o ka noi.

ʻO kahi koho ʻē aʻe inā hopohopo ʻoe e pale aku i nā huahana titanium dioxide micronized, ʻoiai ʻo kēia mea hoʻohui ka mea i hoʻopili ʻia i nā pilikia olakino. E hoʻomanaʻo naʻe, ʻo ka hapa nui o kēia mau pilikia ma muli o ke komo ʻana a i ʻole ka ʻai ʻana i nā nanoparticles titanium dioxide, ʻaʻole mai ka ʻili ʻana.

ʻO ka pale lā maoli, ʻelua micronized a ʻaʻole hoʻi, ʻokoʻa i ko lākou kūlike a me ka manaʻo i ka ʻili. No laila, inā ʻaʻole makemake ʻoe i kekahi brand, e hoʻāʻo i kekahi a loaʻa iā ʻoe ka mea kūpono iā ʻoe.
