Octyl 4-methoxycinnamateKo te (OMC) he mea e whakamahia whānuitia ana hei ārai i te koroheketanga, hei ārai i te hihi ultraviolet, me te nama CAS o 5466-77-3. Ko te tātai ngota ko C18H26O3, ā, ko te taumaha ngota ko 290.4. Ko ngā kupu taurite Hainamana ko te 4-Methoxycinnamic Acid octyl Ester, te 4-methoxycinnamic acid isooctyl ester, me ētahi atu. Ko ngā kupu taurite Ingarihi ko te Isooctyl-4-methoxycinnamate, 2-ethylhexyl-p-methoxycinnamate, Octyl-methoxycinnamate (OMC), me ētahi atu.
Kei roto i te ngota Octyl 4-methoxycinnamate he hononga π nui kua honoa. Mā tēnei hanganga hono ka kitea te āheinga o te matū ki te mimiti i ngā hihi ultraviolet, ka taea te mimiti i ngā hihi ultraviolet i roto i te awhe roangaru o te 280-310nm, me te mimitinga mōrahi i te 311nm, ka ārai pai i te kino o te UVB ki te kiri.
Ko ngā painga matua o te Octyl 4-methoxycinnamate
1. Octyl-methoxycinnamate (OMC)He tino arotahi te hinu ārai rā, ā, ko te nuinga o te aro ki te tiaki i te kiri mai i te UVB. He kaha te mimiti o te OMC i te 311nm, ā, ka taea e ia te ātete i te whitiki matua e puta ai te whero me te wera o te kiri.
2. He tino hototahi te Octyl 4-methoxycinnamate, ā, ka taea te whakakotahi ki ngā hinu ārai rā tūturu pērā i te konutea waikura me te titanium dioxide, ki ngā hinu ārai rā matū rānei pērā i te oxalilin, me te kore e pā ki te pumau o te hua.
3. He pai te āhua o te Isooctyl-4-methoxycinnamate ki te kiri, he wai tōna āhua, ā, he ngāwari te wairewa ki roto i ngā whakarewa waro. Ina tāpirihia ki te hinu ārai rā, kāore te octyl methoxycinnamate e whakararuraru, e whakamā rānei, ā, he pai mō ngā hinu whakahauora.
4. Nā te utu nui, te hangarau whakaputa pakari me te utu tika mō ngā rauemi mata, he mea rongonui te octyl 4-methoxycinnamate mō ngā hua pare-rā utu iti ki te utu waenga-ki-te-pai.
5. He tino pumau te Octyl 4-methoxycinnamate, ā, kāore e pirau i raro i ngā tikanga rokiroki me te whakamahinga noa, e whakarite ana i te roa o te pānga tiaki rā.
He aha ngā whakamahinga o te Octyl 4-methoxycinnamate?
Ko te whakamahinga matua o te octyl methoxycinnamate (CAS 5466-77-3) e pā ana ki te tiaki ultraviolet, e kapi ana i ngā mara pēnei i ngā mea whakapaipai me ngā rauemi ahumahi, penei:
Ngā whakamahinga matua: Te mara whakapaipai (ngā horopaki matua-octyl methoxycinnamate mō te kiri)
Ko te matū matua o te pare rā he hototahi ki ngā momo hua pare rā pērā i te hinu kiri, te kirīmi, te rehu me te tiēre. Ko te Octyl 4-methoxycinnamate e arotahi ana ki te pare UVB hei ārai i te kiri kei whero, kei wera i te rā, kei parauri hoki.
Mā te tāpiri i ngā hua tiaki kiri o ia rā pērā i te toner, te hinu kiri me te hinu kiri, ehara i te mea he mahi tiaki rā me te ārai koroheketanga anake, engari he whakaiti hoki i te kino o ngā hihi ultraviolet ki te kiri.
He rauemi mata motuhake mō ngā hua tiaki kiri, arā, ko te isooctyl-4-methoxycinnamate, e whakamahia ana i roto i ngā hua tiaki kiri hei rongoā āwhina mō te mate kiri pāwera, hei whakamamae i te pāwera o te kiri nā ngā hihi ultraviolet.
Ngā whakamahinga tuarua: Ahumahi me ētahi atu mara
Ngā mea ārai-pakeketanga me ngā mea mimiti hihi ultraviolet mō ngā rauemi kirihou me te kapia, e whakaroa ana i te koroheketanga, te kōwhaitanga me te ngenge o ngā hua kirihou e hua mai ana i te hihi ultraviolet.
Ka whakarei ake te waituhi me ngā tāpiringa paninga i te ātete ki te huarere o ngā hua, ka ārai i te memeha me te pirau i muri i te whitinga o te rā, ā, ka whakaroa i tō rātou ora mahi.
Ina whakamahia ngātahitia me ētahi atu hinu ārai rā, ka taea e te octyl methoxycinnamate te whakatutuki i ngā hiahia tiaki rerekē, me te whakawhānui ake i te whānuitanga o te tiaki ultraviolet o te hua (pēnei i te wā e whakamahia ngātahitia ana me ngā mea mimiti UVA).
Octyl 4-methoxycinnamate He tino pumau, ā, kāore e pirau ina rongoatia i te pāmahana rūma, ā, kia matara atu i te mārama. Ka mau tonu tōna hanganga i roto i te awhe pH (5.5-7.5) o ngā mea whakapaipai noa. Ka taea te whakahaere i te haumaru o te octyl methoxycinnamate. Kua whakaaetia te Octyl-methoxycinnamate (OMC) e ngā mana whakahaere i roto i te maha o ngā whenua hei whakamahi i roto i ngā mea whakapaipai. Ina whakamahia i runga i te whai i ngā ture, he ngawari ki te kiri o te nuinga o te tangata.
