He aha nā Nanoparticles i loko o ka Sunscreen?

Ua hoʻoholo ʻoe ʻo ka hoʻohana ʻana i ka sunscreen kūlohelohe ke koho kūpono nou. Manaʻo paha ʻoe ʻo ia ke koho olakino nou a me ke kaiapuni, a i ʻole ka sunscreen me nā mea hana synthetic e hoʻonāukiuki i kou ʻili palupalu loa.

A laila lohe ʻoe e pili ana i nā "nanoparticles" i loko o kekahi mau pale lā kūlohelohe, me kekahi ʻike hopohopo a kūʻē hoʻi e pili ana i nā ʻāpana i ʻōlelo ʻia e hoʻomaha ai ʻoe. ʻOiaʻiʻo, pono anei ke koho ʻana i kahi pale lā kūlohelohe e huikau loa?

Me ka nui o ka ʻike ma waho, hiki ke manaʻo ʻia he mea nui loa. No laila, e ʻoki kākou i ka walaʻau a nānā pono i nā nanoparticles i loko o ka sunscreen, ko lākou palekana, nā kumu e makemake ai ʻoe iā lākou i loko o kāu sunscreen a me ka wā ʻaʻole ʻoe.

He aha nā Nanoparticles?

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

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

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

Ua like nā huaʻōlelo "nano" a me "micronized". No laila, ʻo ka sunscreen me ka lepili "micronized zinc oxide" a i ʻole "micronized titanium dioxide" aia nā nanoparticles.

ʻAʻole i loaʻa wale nā ​​nanoparticles i nā sunscreens. He nui nā huahana mālama ʻili a me nā mea hoʻonani, e like me nā foundation, shampoos, a me ka toothpaste, loaʻa pinepine nā mea micronized. Hoʻohana ʻia nā nanoparticles i nā mea uila, nā lole, ke aniani pale ʻōpala, a me nā mea hou aku.

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

I ke koho ʻana i kāu sunscreen kūlohelohe, ʻelua āu koho; ʻo ia 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 ʻāpono ʻia ka titanium dioxide a me ka zinc oxide e ka FDA ma ke ʻano he mau mea hoʻohui sunscreen kūlohelohe. Hāʻawi lākou i ka pale UV ākea, ʻoiai ʻoi aku ka maikaʻi o ka titanium dioxide ke hui pū ʻia me ka zinc oxide a i ʻole kekahi mea hoʻohui sunscreen synthetic ʻē aʻe.

Hana ka zinc oxide a me ka titanium dioxide ma ka hoʻohuli ʻana i nā kukuna UV mai ka ʻili aku, e pale ana i ka ʻili mai ka lā. A he kūpono loa lākou.

I ko lākou ʻano maʻamau, ʻaʻole nui ka nui o ka nano, he keʻokeʻo loa ka zinc oxide a me ka titanium dioxide. Ke hoʻohui ʻia i loko o ka sunscreen, e waiho lākou i kahi ʻili keʻokeʻo opaque maopopo ma ka ʻili. E noʻonoʻo i ka lifeguard stereotypical me ke keʻokeʻo ma ke alahaka o ka ihu—ʻae, ʻo ia ka zinc oxide.

E komo i nā nanoparticles. ʻOi aku ka maikaʻi o ka hamo ʻana o ka lā i hana ʻia me ka micronized zinc oxide a me ka titanium dioxide i loko o ka ʻili, a ʻaʻole e waiho i kahi ʻano pasty. ʻO nā nanoparticles ultra-fine e hoʻolilo i ka sunscreen i emi iki ka opaque akā like ka maikaʻi.

Ua ʻike ka hapa nui o ka noiʻi i nā nanoparticles i loko o ka Sunscreen Safe

Mai ka mea a mākou e ʻike nei i kēia manawa, ʻaʻole like me he mea lā he mea ʻino nā nanoparticles o ka zinc oxide a i ʻole ka titanium dioxide. Eia nō naʻe, he mea pohihihi iki nā hopena lōʻihi o ka hoʻohana ʻana i ka micronized zinc oxide a me ka titanium dioxide. I nā huaʻōlelo ʻē aʻe, ʻaʻohe hōʻike e palekana loa ka hoʻohana lōʻihi, akā ʻaʻohe hōʻike he mea ʻino hoʻi.

Ua nīnau kekahi i ka palekana o kēia mau ʻāpana micronized. No ka mea, he liʻiliʻi loa lākou, hiki ke omo ʻia e ka ʻili a i loko o ke kino. ʻO ka nui o ka omo ʻia a me ka hohonu o ko lākou komo ʻana, pili ia i ka liʻiliʻi o nā ʻāpana zinc oxide a i ʻole titanium dioxide, a pehea lākou e lawe ʻia ai.

No ka ʻakaʻaka, he aha ka mea e hana ʻia i kou kino inā e omo ʻia nā nano-particles zinc oxide a i ʻole titanium dioxide? ʻO ka mea pōʻino, ʻaʻohe pane maopopo no kēlā.

Aia kekahi kuhi e hoʻokaumaha a hōʻino paha lākou i nā hunaola o ko kākou kino, e hoʻolalelale ana i ka ʻelemakule ma loko a ma waho. Akā, pono e hana hou ʻia ka noiʻi e ʻike pono ai i kekahi ʻano a i ʻole kekahi.

Ua hōʻike ʻia ka titanium dioxide, i kona ʻano pauka a hanu ʻia, e hoʻoulu ai i ka maʻi kanesa māmā i nā ʻiole lab. Hoʻokomo pū ka titanium dioxide micronized i loko o ka ʻili i ʻoi aku ka hohonu ma mua o ka zinc oxide micronized, a ua hōʻike ʻia ka titanium dioxide e hele ma waena o ka placenta a hoʻopili i ka pale koko-lolo.

E hoʻomanaʻo naʻe, ʻo ka hapa nui o kēia ʻike mai ka ʻai ʻana i ka titanium dioxide (ʻoiai ua loaʻa ia i loko o nā meaʻai a me nā mea ʻono i hoʻopaʻa mua ʻia). Mai nā haʻawina he nui o ka titanium dioxide micronized i hoʻopili ʻia ma ke ʻano topical a me ka zinc oxide, i kekahi manawa wale nō i loaʻa ai kēia mau mea i loko o ka ʻili, a ʻoiai i kēlā manawa aia lākou i loko o nā ʻano haʻahaʻa loa.

ʻO ia hoʻi, inā ʻoe e hoʻopili i kahi sunscreen me nā nanoparticles, ʻaʻole paha lākou e omo ma mua o ka papa mua o ka ʻili. ʻOkoʻa loa ka nui o ka mea i omo ʻia ma muli o ke ʻano o ka sunscreen, a ʻo ka hapa nui o ia mea ʻaʻole e omo hohonu inā loaʻa.

Me ka ʻike i loaʻa iā mākou i kēia manawa, ʻike ʻia he palekana a he pono loa nā nanoparticles sunscreen. ʻAʻole maopopo loa ka hopena o ka hoʻohana lōʻihi ʻana o ka huahana i kou olakino, ʻoiai inā ʻoe e hoʻohana ana i ka huahana i kēlā me kēia lā. Eia hou, ʻaʻohe hōʻike e hōʻino ana ka hoʻohana lōʻihi ʻana o ka micronized zinc oxide a i ʻole titanium dioxide, ʻaʻole mākou i ʻike i kona hopena (inā he) i kou ʻili a i ʻole ke kino.

He ʻŌlelo Mai Verywell

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

Nui nā ʻano pale lā kūlohelohe i loaʻa, nā koho nano a me nā koho non-nano, aia nō kahi huahana nou. ʻO ka hoʻohana ʻana i ka pale lā me ka micronized (AKA nano-particle) zinc oxide a i ʻole titanium dioxide e hāʻawi iā ʻoe i kahi huahana i emi iki ka pasty a hamo hou aku.

Inā ʻoe e hopohopo nei e pili ana i nā nano-particles, ʻo ka hoʻohana ʻana i kahi sunscreen non-micronized e hāʻawi iā ʻoe i nā ʻāpana nui aʻe i emi iki ka omo ʻia e kou ʻili. ʻO ke kūkaʻi ʻana, e ʻike ʻoe i kahi ʻili keʻokeʻo ma kou ʻili ma hope o ka hoʻopili ʻana.

ʻO kekahi koho inā ʻoe e hopohopo nei, ʻo ia ke pale aku i nā huahana titanium dioxide micronized āpau, ʻoiai ʻo kēia mea hoʻohui ka mea i pili i nā pilikia olakino. E hoʻomanaʻo naʻe, ʻo ka hapa nui o kēia mau pilikia mai ka hanu ʻana a i ʻole ka ʻai ʻana i nā nanoparticles titanium dioxide, ʻaʻole mai ka omo ʻana o ka ʻili.

ʻOkoʻa loa ka ʻano o ka sunscreen kūlohelohe, ʻelua i micronized a ʻaʻole hoʻi, i ko lākou kūlike a me ka manaʻo ma ka ʻili. No laila, inā ʻaʻole makemake ʻoe i kekahi brand, e hoʻāʻo i kekahi a loaʻa iā ʻoe ka mea e kūpono iā ʻoe.
