O le Octyl methoxycinnamate, e taʻua foi o le ethylhexyl methoxycinnamate (EHMC), o se faʻalapotopotoga faʻapitoa e faʻaaoga muamua e fai ma faʻamama UV i le tele o mea teuteu ma mea tau le tagata lava ia. O loʻo i ai le vailaʻau faʻasolosolo C16H24O3 ma o loʻo faʻavasegaina o se ester methoxycinnamate. O lenei tuufaatasiga ua lauiloa lautele ona o lona gafatia e mitiia ai le ultraviolet (UV) radiation, aemaise o le UVB ave, e afaina ai le paʻu o le tagata.

 

Fauga ma Meatotino

I le vailaʻau, octyl methoxycinnamate e maua mai le methoxycinnamic acid, o se mea e maua mai i le cinnamic acid ma se vaega methoxy faʻapipiʻi. O le octyl moiety, e maua mai i le 2-ethylhexanol, e tuʻuina atu ai le tuʻufaʻatasia ma mea lipophilic, e mafai ai ona solu i totonu o suauʻu ma isi solvents organic, ma faʻaleleia ai lona fesoʻotaʻiga ma mea faʻalelei.

O le Octyl methoxycinnamate o loʻo faʻaalia ai se fusi o le faʻaogaina o le UV, faʻamuamua le mitiia o le UVB i le va o le 280 i le 320 nanometers (nm). E taua tele lenei vaega ona o ave o le UVB e nafa ma le mu o le la ma fesoasoani i le faaleagaina o le paʻu, e aofia ai le matua vave ma le faʻateleina o le lamatiaga o le kanesa o le paʻu. O le mitiia o nei ave leaga, o le octyl methoxycinnamate e fesoasoani e puipuia le paʻu mai nei aʻafiaga leaga.

Fa'aoga i mea teuteu ma mea e puipui ai le la

I totonu o fale gaosi oloa, octyl methoxycinnamate o se mea e faʻaaogaina lautele i faʻasologa o le la. E masani ona tu'ufa'atasia ma isi fa'amama UV e fa'atupu ai fa'amalama o le la e ofoina atu le puipuiga mai le fa'avelaina o le UVA ma le UVB.

E tusa ai ma nei faʻalapotopotoga, octyl methoxycinnamate e manatu e saogalemu mo le faʻaogaina i oloa teuteu, e aofia ai le sunscreens, pe a faʻaaogaina i totonu o tapulaa faʻatonuga.

Peita'i, e pei o vaila'au uma o le UV filiga, o le octyl methoxycinnamate e iai ni a'afiaga leaga pe a fa'aaoga sese pe afai e sili atu le fa'atonuga i tulaga fautuaina. O nisi su'esu'ega ua fa'ailoa mai e ono fa'atupu ai le ita po'o fa'ama'i i tagata ma'ale'ale. O le mea lea, e taua mo le au gaosi oloa ona tausisi i taʻiala o loʻo tuʻuina mai e faʻalapotopotoga faʻatonutonu ma mo tagata faʻatau e faitau ma le faʻaeteete ma mulimuli i faʻatonuga o le faʻaaogaina.

Aafiaga Faalesiosiomaga

Ole aafiaga ole siosiomaga ole octyl methoxycinnamate ole autu ole su'esu'ega faifaipea. O nisi su'esu'ega ua fa'aalia ai e mafai ona i ai se aafiaga o'ona fa'alagolago ile fa'atonuga i meaola vai, aemaise ile maualuga maualuga. O lea ua mafua ai popolega i le ono mafai ona faaputuputu i totonu o le gataifale, aemaise lava i le gataifale o loʻo tele le faʻaogaina o mea e puipuia ai le la.

O le i'uga, o lo'o fa'atupula'ia le fiafia i le atina'eina o isi mea e fa'alelei ai le la. E ui o le octyl methoxycinnamate o loʻo tumau pea le faʻaogaina lautele ma le aoga o le UV faamama, o lona aʻafiaga o le siosiomaga na faʻaosofia ai le sailiga mo ni filifiliga sili atu ona gafatia, e pei o poloka faʻapitoa (faʻataʻitaʻiga, zinc oxide ma titanium dioxide) ma vailaʻau fou e faʻaitiitia ai le afaina o le ola vai.
