ʻOktil 4-methoxycinnamateʻO (OMC) kahi mea pale lā i hoʻohana pinepine ʻia, mea anti-aging a me ka mea hoʻomoʻa ultraviolet, me ka helu CAS o 5466-77-3. ʻO ke ʻano molekala ʻo C18H26O3 a ʻo ke kaumaha molekala he 290.4. ʻO nā huaʻōlelo like Kina e komo pū me 4-Methoxycinnamic Acid octyl Ester, 4-methoxycinnamic acid isooctyl ester, a pēlā aku. ʻO nā huaʻōlelo like Pelekania e komo pū me Isooctyl-4-methoxycinnamate, 2-ethylhexyl-p-methoxycinnamate, Octyl-methoxycinnamate (OMC), a pēlā aku.

Aia i loko o ka molekole Octyl 4-methoxycinnamate kahi pilina π nui i hoʻohui ʻia. Hoʻoholo kēia ʻano hoʻohui ʻia he waiwai ka mea o ka omo ʻana i nā kukuna ultraviolet, hiki ke omo i nā kukuna ultraviolet i loko o ka pae nalu o 280-310nm, me ka omo nui loa ma 311nm, e pale pono ana i ka hōʻino ʻana o ka UVB i ka ʻili.

ʻO nā pono koʻikoʻi o Octyl 4-methoxycinnamate

1. ʻOktil-methoxycinnamate (OMC)Ua kuhikuhi nui ʻia ka sunscreen a ke kālele nui nei i ka pale UVB. Loaʻa iā OMC kahi piko absorption ikaika ma kahi o 311nm a hiki ke pale pono i ke kāʻei kī e hoʻoulu ai i ka ʻulaʻula o ka ʻili a me ka lā.

2. Loaʻa i ka Octyl 4-methoxycinnamate ka hoʻohālikelike maikaʻi loa a hiki ke hoʻohui ʻia me nā sunscreens kino e like me ka zinc oxide a me ka titanium dioxide, a i ʻole nā ​​​​sunscreens kemika e like me ka oxalilin, me ka ʻole o ka hoʻopilikia ʻana i ke kūpaʻa o ka huahana.

3. He ʻano ʻoluʻolu ka ʻili o Isooctyl-4-methoxycinnamate, aia i loko o ke ʻano wai a maʻalahi hoʻi e hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik. Ke hoʻohui ʻia i ka sunscreen, ʻaʻole e hoʻoulu ka octyl methoxycinnamate i ke kaumaha a i ʻole nā ​​pilikia keʻokeʻo, a kūpono ia no nā ʻano hana hou.

4. Me ka hana kumukūʻai kiʻekiʻe, ka ʻenehana hana makua a me nā kumukūʻai maka maka kūpono, ʻo ka octyl 4-methoxycinnamate kahi koho maʻamau no nā huahana sunscreen kūpono a waena a kiʻekiʻe.

5. Loaʻa i ka Octyl 4-methoxycinnamate ke kūpaʻa maikaʻi loa a ʻaʻole ia e palaho ma lalo o nā kūlana mālama a me ka hoʻohana maʻamau, e hōʻoiaʻiʻo ana i ka lōʻihi o ka hopena pale lā.

He aha nā hoʻohana o ka Octyl 4-methoxycinnamate?

ʻO ka hoʻohana nui ʻana o ka octyl methoxycinnamate (CAS 5466-77-3) e pili ana i ka pale ultraviolet, e uhi ana i nā kahua e like me nā mea hoʻonani a me nā mea hana ʻoihana, penei:

Nā hoʻohana nui: Kahua hoʻonani (nā hiʻohiʻona koʻikoʻi-ʻO ka octyl methoxycinnamate no ka ʻili)

ʻO ka mea nui o ka pale lā o ka sunscreen he kūpono ia me nā huahana pale lā like ʻole e like me ka lotion, kirīmi, spray a me ka gel. Hoʻoikaika ʻo Octyl 4-methoxycinnamate i ka pale UVB e pale i ka ʻili mai ka ʻulaʻula, ka puhi ʻana i ka lā a me ka ʻeleʻele.

ʻO ka hoʻohui ʻana i nā huahana mālama ʻili i kēlā me kēia lā e like me ka toner, essence a me ka lotion ʻaʻole wale nā ​​​​hana o ka pale ʻana i ka lā a me ka anti-aging, akā e hōʻemi ana hoʻi i ka photodamage o nā kukuna ultraviolet i ka ʻili.

ʻO nā mea maka o ka huahana mālama ʻili kūikawā, ʻo isooctyl-4-methoxycinnamate, i hoʻohana ʻia i nā huahana mālama ʻili no ka mālama kōkua ʻana i ka dermatitis photosensitive, e hōʻoluʻolu i ka ʻike o ka ʻili i hoʻokumu ʻia e nā kukuna ultraviolet.

Nā hoʻohana lua: ʻOihana a me nā kahua ʻē aʻe

ʻO nā mea anti-kahiko a me nā mea hoʻoheheʻe ultraviolet no nā mea plastik a me nā resin, e hoʻopaneʻe ana i ka ʻelemakule, melemele a me ka embrittlement o nā huahana plastik i hoʻokumu ʻia e ka radiation ultraviolet.

Hoʻonui ka ʻīnika a me nā mea hoʻohui uhi i ke kūpaʻa o nā huahana i ka wā, pale i ka mae ʻana a me ka palaho ma hope o ka ʻike ʻana i ka lā, a hoʻolōʻihi i ko lākou ola lawelawe.

Ke hoʻohana ʻia me nā sunscreens ʻē aʻe, hiki i ka hoʻohana ʻana o octyl methoxycinnamate ke hoʻokō i nā pono palekana like ʻole a hoʻonui i ka laulā pale ultraviolet o ka huahana (e like me ka hui pū ʻana me nā mea hoʻomoʻa UVA).

ʻOktil 4-methoxycinnamate He kūpaʻa maikaʻi loa kona a ʻaʻole ia e palaho ke mālama ʻia ma ka mahana o ka lumi a ma kahi ʻē aʻe mai ka mālamalama. Noho paʻa kona ʻano i loko o ka pae pH (5.5-7.5) o nā mea hoʻonani maʻamau. Hiki ke hoʻomalu ʻia ka palekana octyl methoxycinnamate. Ua ʻae ʻia ʻo Octyl-methoxycinnamate (OMC) e nā luna hoʻoponopono ma nā ʻāina he nui no ka hoʻohana ʻana i nā mea hoʻonani. Ke hoʻohana ʻia e like me nā lula, he akahai ia i ka ʻili o ka hapa nui o ka poʻe.
