UV Sefa Octyl Methoxycinnamate CAS 5466-77-3 Octyl 4-Methoxycinnamate

Octyl methoxycinnamate, inozivikanwawo se ethylhexyl methoxycinnamate (EHMC), ndeye organic compound inonyanya kushandiswa seUV sefa mune zvakasiyana siyana zvekuzora uye zvekuchengeta zvigadzirwa. Iine chimiro chemakemikari C16H24O3 uye inorondedzerwa se methoxycinnamate ester. Mushonga uyu unozivikanwa zvakanyanya nekugona kwayo kutora ultraviolet (UV) mwaranzi, kunyanya UVB mwaranzi, iyo inokuvadza paganda remunhu.

Kemikari Mamiriro uye Zvivakwa

Kemikari, octyl methoxycinnamate inotorwa kubva kune methoxycinnamic acid, inova kubva kune cinnamic acid ine methoxy boka rakabatanidzwa. Iyo octyl moiety, inotorwa kubva ku2-ethylhexanol, inopa iyo komputa ine lipophilic properties, ichiita kuti inyungudike mumafuta uye mamwe organic solvents, nekudaro ichiwedzera kuenderana kwayo necosmetic formulations.

Octyl methoxycinnamate inoratidza yakananga UV absorption spectrum, inonyanya kutora UVB mwaranzi pakati pe280 kusvika 320 nanometers (nm). Rudzi urwu rwakanyanya kukosha nekuti mwaranzi yeUVB inokonzera kupisa kwezuva uye inobatsira mukukuvadzwa kweganda, kusanganisira kuchembera nguva isati yakwana uye njodzi yakawedzera yegomarara reganda. Nekutora mwaranzi iyi inokuvadza, octyl methoxycinnamate inobatsira kuchengetedza ganda kubva kune izvi zvakaipa zvinokonzeresa.

Inoshandiswa muCosmetics uye Sunscreen Zvigadzirwa

Muindasitiri yezvizorwa, octyl methoxycinnamate chinhu chinoshandiswa zvakanyanya mukugadzirwa kwezuva. Inowanzo kusanganiswa nemamwe mafirita eUV kuti igadzire mafiritsi ezuva akafararira anopa dziviriro kubva kune ese UVA neUVB mwaranzi. Iko kusanganiswa kwemafirita akasiyana kwakakosha nekuti yega yega sefa inotora yakatarwa huwandu hwewavelengths, nekudaro ichipa kuchengetedzwa kwakazara.

Masikirini ezuva ane octyl methoxycinnamate anowanzo kugadzirwa kuti asapinda mumvura, kuve nechokwadi chekuti chigadzirwa chinoramba chichishanda kunyangwe mushure mekusangana nemvura kana dikita. Izvi zvinonyanya kukosha kune zviitiko zvekunze nemitambo, uko zvechinyakare sunscreens zvinogona kugezwa, zvichisiya ganda riri panjodzi yekukuvadzwa kweUV.

Chengetedzo uye Regulatory Kufunga

Kuchengeteka kweoctyl methoxycinnamate kwakaongororwa zvakanyanya nemasangano anodzora akadai seUS Food and Drug Administration (FDA) neEuropean Commission's Scientific Committee on Consumer Safety (SCCS). Zvinoenderana nemasangano aya, octyl methoxycinnamate inonzi yakachengeteka kuti ishandiswe muzvigadzirwa zvekuzora, zvinosanganisira sunscreens, kana ichishandiswa mukati memiganhu yakatarwa.

Nekudaro, senge ese kemikari mafirita eUV, octyl methoxycinnamate ine mukana wemhedzisiro yakaipa kana ikashandiswa zvisizvo kana iyo yekumisikidza yakapfuura mazinga anokurudzirwa. Zvimwe zvidzidzo zvakaratidza kuti zvinogona kukonzera kushatirwa kana kusawirirana muvanhu vane hanya. Naizvozvo, zvakakosha kuti vagadziri vatevedzere zvinongedzo zvinopihwa nemasangano anodzora uye kuti vatengi vanyatsoverenga nekutevera mirairo yekushandiswa.

Environmental Impact

Kukanganisa kwezvakatipoteredza kweoctyl methoxycinnamate inyaya yekuenderera mberi nekutsvaga. Zvimwe zvidzidzo zvakaratidza kuti inogona kuve ne-concentration-inoenderana nechepfu mhedzisiro pane zvipenyu zvemumvura, kunyanya pamazinga epamusoro. Izvi zvakakonzera kunetseka pamusoro pekugona kuunganidza munzvimbo dzegungwa, kunyanya munzvimbo dzemahombekombe uko kune kushandiswa kukuru kwezvigadzirwa zvezuva.

Nekuda kweizvozvo, kune kufarira kuri kukura mukugadzirwa kwemamwe masikirwo ezuva anochengetedza nharaunda. Nepo octyl methoxycinnamate ichiramba ichishandiswa zvakanyanya uye inoshanda sefa yeUV, kukanganisa kwayo kwezvakatipoteredza kwakakurudzira kutsvaga dzimwe sarudzo dzakasimba, dzakadai sezvivhariso zvemuviri (semuenzaniso, zinc oxide uye titanium dioxide) uye mafirita emakemikari matsva asinganyanye kukuvadza hupenyu hwemumvura.
