Octyl methoxycinnamate, tseem hu ua ethylhexyl methoxycinnamate (EHMC), yog ib qho organic compound feem ntau siv los ua UV lim hauv ntau yam khoom siv tshuaj pleev ib ce thiab kho tus kheej. Nws muaj cov tshuaj formula C16H24O3 thiab raug cais raws li methoxycinnamate ester. Qhov sib xyaw no tau lees paub dav dav rau nws lub peev xwm los nqus ultraviolet (UV) hluav taws xob, tshwj xeeb tshaj yog UVB rays, uas muaj teeb meem rau tib neeg cov tawv nqaij.

 

Chemical Structure thiab Properties

Chemically, octyl methoxycinnamate yog muab los ntawm methoxycinnamic acid, uas yog derivative ntawm cinnamic acid nrog ib pawg methoxy txuas. Lub octyl moiety, muab los ntawm 2-ethylhexanol, muab cov compound nrog lipophilic zog, ua rau nws soluble nyob rau hauv cov roj thiab lwm yam organic solvents, yog li pab tau nws compatibility nrog cov tshuaj pleev ib ce formulations.

Octyl methoxycinnamate nthuav tawm ib qho tshwj xeeb UV nqus spectrum, feem ntau nqus UVB hluav taws xob hauv thaj tsam ntawm 280 txog 320 nanometers (nm). Qhov no yog qhov tseem ceeb tshwj xeeb vim tias UVB rays yog lub luag haujlwm rau kev tshav ntuj thiab ua rau cov tawv nqaij puas tsuaj, nrog rau kev laus ntxov ntxov thiab muaj kev pheej hmoo ntawm cov qog nqaij hlav ntawm daim tawv nqaij. Los ntawm kev nqus cov kab hluav taws xob tsis zoo no, octyl methoxycinnamate pab tiv thaiv daim tawv nqaij los ntawm cov teebmeem no.

Siv rau hauv cov khoom siv tshuaj pleev ib ce thiab tshuaj pleev thaiv hnub

Hauv kev lag luam tshuaj pleev ib ce, octyl methoxycinnamate yog cov khoom siv dav hauv cov tshuaj pleev thaiv hnub. Nws feem ntau ua ke nrog lwm cov lim UV los tsim cov tshuaj pleev thaiv hnub dav dav uas muaj kev tiv thaiv UVA thiab UVB hluav taws xob. Kev sib xyaw ua ke ntawm cov lim dej sib txawv yog qhov tseem ceeb vim tias txhua hom lim absorbs ib qho tshwj xeeb ntawm wavelengths, yog li muab kev tiv thaiv zoo.

Cov tshuaj pleev thaiv hnub uas muaj octyl methoxycinnamate feem ntau yog tsim los ua dej-resistant, kom ntseeg tau tias cov khoom tseem zoo txawm tias tom qab raug dej los yog hws. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau kev ua si sab nraum zoov thiab kev ua kis las, qhov twg cov tshuaj pleev thaiv hnub niaj hnub yuav raug ntxuav tawm, ua rau cov tawv nqaij muaj kev puas tsuaj rau UV.

Kev nyab xeeb thiab kev txiav txim siab

Kev nyab xeeb ntawm octyl methoxycinnamate tau raug soj ntsuam ntau los ntawm lub koom haum tswj hwm xws li US Food and Drug Administration (FDA) thiab European Commission's Scientific Committee on Consumer Safety (SCCS). Raws li cov koom haum no, octyl methoxycinnamate yog suav tias yog kev nyab xeeb rau kev siv hauv cov khoom siv tshuaj pleev ib ce, nrog rau cov tshuaj pleev thaiv hnub, thaum siv nyob rau hauv cov kev txwv tshwj xeeb.

Txawm li cas los xij, zoo li tag nrho cov tshuaj UV lim dej, octyl methoxycinnamate muaj peev xwm ua rau muaj kev phom sij yog tias siv tsis raug lossis yog tias qhov concentration siab tshaj qhov pom zoo. Qee qhov kev tshawb fawb tau pom tias nws yuav ua rau khaus lossis ua xua rau cov tib neeg rhiab heev. Yog li ntawd, nws yog ib qho tseem ceeb rau cov tuam txhab lag luam kom ua raws li cov lus qhia los ntawm lub koom haum tswj hwm thiab cov neeg siv khoom kom ua tib zoo nyeem thiab ua raws li cov lus qhia siv.

Environmental Impact

Qhov cuam tshuam ib puag ncig ntawm octyl methoxycinnamate yog lub ntsiab lus ntawm kev tshawb fawb tsis tu ncua. Qee qhov kev tshawb fawb tau pom tias nws tuaj yeem muaj cov tshuaj lom neeg muaj txiaj ntsig zoo rau cov kab mob hauv dej, tshwj xeeb tshaj yog nyob rau qib siab dua. Qhov no tau ua rau muaj kev txhawj xeeb txog qhov muaj peev xwm rau nws khaws cia hauv thaj chaw marine, tshwj xeeb tshaj yog nyob rau hauv cov ntug dej hiav txwv uas muaj cov khoom siv tshuaj pleev thaiv hnub tseem ceeb.

Yog li ntawd, muaj kev txaus siab ntau ntxiv rau kev tsim cov tshuaj tiv thaiv ib puag ncig ntau dua. Thaum octyl methoxycinnamate tseem siv dav thiab siv tau zoo UV lim, nws qhov kev cuam tshuam ib puag ncig tau ua rau muaj kev tshawb nrhiav ntau dua kev xaiv, xws li lub cev blockers (xws li zinc oxide thiab titanium dioxide) thiab cov lim dej tshiab uas tsis muaj teeb meem rau cov dej hauv lub neej.
